Earthquake

Earthquake - 08/06/2012 22:08

I am sure I felt an earthquake just now.
In Manilla, NSW, in a house on a concrete slab on bedrock.
Time 21:31 EST, 8 June 2012, two sharp shocks 10 seconds apart, with shaking fading over several seconds.
Time 21:33 EST, 8 June 2012, two sharp shocks 10 seconds apart, the second one stronger, with shaking fading over several seconds.
The house shook, and double-glazed windows rattled.

I tried to access Geosciences Australia's earthquake reporting website, but got: "The connection to www.ga.gov.au was interrupted."

The epicentre plots near "Manilla Ski Gardens" at the north end of Lake Keepit, but I see that the Uncertainty of Location means it could be right here at Manilla. The shocks were very sharp, like a truck running into the house.

2 distinct shakes in Tamworth, about 30 secs apart. House shook, rumbling noise like a train and every dog in the neighbourhood howling. No damage but instant reminder of Newcastle when I was tossed out of a bed in Woolongong!!!!!

The two shocks were 13 seconds apart, when I had guessed 10. And the second set was not quite two minutes later.

Re: Earthquake - 08/06/2012 23:18

4.3! That's a fair shake. Uni friends in Armidale and Tamworth are saying they felt the earthquake.
Never felt an earthquake before, makes me wish I was still up there just to experience it.

Re: Earthquake - 09/06/2012 02:07

According to this article, it is the first earthquake stronger than magnitude 4 in the region since December 1969:
http://au.news.yahoo.com/a/-/latest/13910012/two-earthquakes-shake-northern-nsw/

Relatives at Barraba felt the quake, and two friends in Uralla felt it as well.
From your report Orion and from others I know in Tamworth, it sounds like it was a fairly unsettling experience. Some were not keen on going back to bed.

EMERGENCY services were inundated with calls last night as an earthquake shook a large section of the North West.

The 4.2 magnitude quake hit just after 9.30pm and was felt across the region, including Tamworth, Manilla, Gunnedah, Barraba, Tingha, Armidale, Uralla, Inverell and Tambar Springs.

In Tamworth it was felt as two sharp tremors, about 30 seconds apart.

One resident said the second tremor felt like “something hit the house”.

A spokesman for Geoscience Australia told The Leader the quake was 52km north west of Tamworth, near Manilla, 17km under the surface.

He said it was caused by movement of rock along a local fault line and it was possible some smaller tremors, or aftershocks, may be felt in the next few days.

Australia felt these type of quakes “fairly regularly”, he said, but in the past 10 years in NSW there’s only been two earthquakes of last night’s size – one in Cowra and another in Bowral.

Police were swamped by hundreds of calls from concerned residents, but there had been no reports of damage or injuries when The Leader went to press last night.

Linky: http://www.northerndailyleader.com.au/ne...226.aspx?page=2

It will probably be the lead story on Prime and NBN Local News this evening across the New England - North West. The earthquake was the second news item on Ten News this evening.

As relatives in Barraba described the quake (with one word substituted, lol): 'Scared the living "poop" out of us. Shook us and the house.'

Re: Earthquake - 15/06/2012 23:51

Something funny has happened to Manilla's earthquake of the 8th of June.

The US Geological survey and Geoscience Australia initially agreed that the epicentre was 17 km west of Manilla and 17 km deep. A seismogram from Armidale was published showing a time of 11:31:05 UTC, with another, slightly larger shock two minutes later. This agrees with What Orion copied from Geoscience Australia, and what I observed at Manilla.
Now Geoscience Australia denies this:
http://www.ga.gov.au/earthquakes/getQuakeDetails.do?quakeId=3223789&orid=2156260&sta=
GA says the earthquake was at 11:32:39 UTC, a time between the two shocks stated earlier - a large error. It says the location is at coordinates that are 30 km west of Manilla (which could be an improved estimate) but that the depth and most other data, including seismograms, are "not available", even though the Solution is "Finalised" as of 12 June.

I feel that we ought to be told why the data is "not available".

The US Geological Survey is sticking by their analysis, which has been "REVIEWED".
http://earthquake.usgs.gov/earthquakes/eventpage/usb000aagx#technical
However, seismograms are now "not available" although the Armidale seismogram was previously published on this page, as I linked above.

Re: Earthquake - 16/06/2012 01:11

The new estimate for position of the earthquake gives a plausible link to a major fault.
It is only 13 km east of the Hunter-Mooki Fault, also known as the Mooki Thrust (the most western black line on Seabreeze's geological map).
That fault plane dips east at about 1 km depth for 2 km horizontally. So a vertical line from the estimated epicentre would meet the fault about 6 or 7 km below.
The Mooki Thrust is a very important geological boundary. All our coal is west of the thrust, here in Permian rocks. East of the thrust are older rocks that are more folded. The older rocks have been pushed up over the coal-bearing rocks, and perhaps are still moving up over them today. I don't understand the conventional diagram well enough to know whether the movement in the earthquake was in that sense.

Re: Earthquake - 19/06/2012 22:38

There was a sway from side to side before the rumble hit - it was a weird, surreal feeling.
All the dogs went ballistic; the cats shot under the tables; apparently the phone lines went down in Dandenong (area).
Waiting for an aftershock/tremor.

Re: Earthquake - 19/06/2012 22:48

Yeah , definitely felt it here ( Near Frankston ) .....

Unfortunately was dozing on the couch , but woke the whole house wife & 2 kids .

Didn't feel the intial " Sway" , but presume was what woke me up , almost rolled off the couch . ( have been in Indonesia during some solid ones , so half sleepy reaction , was to " get to high ground " , but then reality of realising was back in Aust. kicked in and enjoyed the rest of it .

I swear i could feel the rumble . see saw effect to be East to west . So was was surprised to be right that it's Epicentre was due East of here .

There's been a few more in Vic in the last ten years , than the Twenty preceding that for Sure ...

Definitely the biggest I've ever felt, and I'm up in Wangaratta. It felt different to others I've experienced - I was in my lounge chair at the time and the force moved me up and down a few times like I was in a boat going over a series of waves. It all happened so quick but I swear I saw the walls move a bit too. Absolutely freaky stuff!!

From memory the last tremor that we had in Wang was from a massive boulder falling in the warby ranges?

Re: Earthquake - 20/06/2012 09:34

There are two main types of seismic wave that spread out from an earthquake hypocentre:
P-wave: the primary (or "Push") wave that arrives first, travelling at several kilometres per second;
S-wave: the Secondary (or "Shake") wave that arrives later.
"A quick way to determine the distance from a location to the origin of a seismic wave less than 200 km away is to take the difference in arrival time of the P wave and the S wave in seconds and multiply by 8 kilometers per second."
http://en.wikipedia.org/wiki/Seismic_wave

At Manilla, the June 8 earthquake S-wave arrived about 10 seconds after the P-wave, indicating a distance (to the west) of 80 km. I am only guessing the 10 seconds. Armidale, in the "not available" seismogram, had the S-wave 13 seconds after the P-wave, giving a distance of 104 km. This agrees with the official first estimate of the epicentre location.

Obviously though, the damage at the epicentre and in other places will be more substantial.

Reposted We will rebuild image to FB - Love it. wink

Because earthquakes/tremors are faily rare in Australia the media hype went into over drive even before any offical reports had been issued.
Plenty of panic and lots of rumours etc. Having lived in PNG and having tremors on an almost daily basis in some location we lived in we too where pretty frightened when it happened but after a couple of days soon got used to them.

Re: Earthquake - 23/06/2012 08:54

If there is a volcano forming in bass Strait the pressure on the plate would be immense. Even though its not on the edge of the plate its stressing and weakening and being squeezed to the vertical.

Geologists say that the 2002 tremor at Flinders Island re-awakened the area and have identified it as Australias hot spot. Hence the forecast of larger quakes to come.

Re: Earthquake - 24/06/2012 10:09

Cheers Gabby and LQQKN.
I believe quality info is important to have under one's belt. Not necessarily to become panicked, but aware and realistic about potential hazards, instead of being complacent or too laid back.
That last earthquake was, for me, an unusual feeling. My equalibrium, with the side to side sway, was definitiely challenged. I've experienced a few EQ's in my time, but the movement of this one awakened my awareness (or lessened my complacency) about 'types' of EQ's possible.
I know my NZ friends in Christchurch had and are still nerve-rattled, even shattered, with what they have and are experiencing still. We had a small taste of this recently with our 5.3
Anyway, I am not only a bit of a weather (albeit amateur) geek, but fascinated with Mother Nature too (you could say, a geology/seismology geek smile ) .

Was just saying, earlier this week, to my cousin (the one in NZ - a seismologist) that I felt that something was building again. Not that I am a prediction wiz, but just felt it.
The first one in this lot was a 7M.
Hopefully it has released its 'energy' and it'll settle now.

Went to check on my faithful pendulum, and it was quietly moving from side to side by about 5mm both ways.

There was a 'flurry' of sizable quakes along various points of the 'Ring of Fire' within a one hour period, at one point in the last 24-36 hours.
New Zealand's North Island, halfway between Auckland and Wellington has just had another 5.7M, 10kms south of Turangi (in the middle of the island), in the last half hour.
And just another of 5M in the same spot.
And another of 5.3M.
I know NZ is a fairly active seismic zone, compared to Oz. I have friends and family there, so I suppose my interest in these happenings is of a personal nature.

Re: Earthquakes - 10/07/2012 21:58

Ok....a little spooky..but the earthquakes (all near M5's) all down the eastern side of the ring of fire today, I had predicted.
Was just saying to one of my sons an hour ago that NZ (near Christchurch) was gonna get an M5 and they just did 25 minutes ago.
Ok...not pleased with myself as people usually are poorly affected by these earthquake occurrences.
Will keep a keen eye on NZ.
Got a feeling that if there is so much M5 occurences along the east side of the ring of fire, that even the east coast (Melb.?) may experience a minor reverberation from this...will see...

Re: Earthquakes - 11/07/2012 10:13

Just thought I'd gabble on here, for anyone who is interested smile
A noticable 'trend' in the quakes involving Fiji, Kuril islands (Japan), Japan, Vanuatu, NZ, PNG and so on (all down 'left' of ring of fire), is that they have been around/above M5.
Within the last hour PNG had a couple of near/over M5's, with the last PNG and Fiji quakes being very deep.
The Greece/Turkey region has been constantly 'rumbling' with clusters of smaller quakes. As has the California area - which seems to be constantly releasing its' tension in small bursts. Got an uncomfortable feeling about these two regions.
Alaska is 'clustering' too.

Re: Earthquakes - 11/07/2012 13:12

More M5+ earthquakes happening again in last 3 or so hours from Kuril Islands - Japan, through to Solomons, Indonesia + PNG.
I am guessing Japan (northish)/Philippines will experience another very soon?
Also feel NZ may get another as well....
Posted by: Anthony Violi

Re: Earthquakes - 11/07/2012 18:36

Yeah definitely something going on in the Kuril Islands region.

Also duckweather, all the action is in this saide and the Japan side, nothing on the US side. You would think surely that something would have to give on that side with all the movement everywhere else?

BTw i think something major around Indonesia..
Posted by: duckweather

Re: Earthquakes - 11/07/2012 19:02

Hi Anthony smile
The Gulf of California (and surrounds) is grumbling away, as is the Chile/Argentina region. I think California will see an M5+ sooner rather than later, given the clusters.
Japan will be visited by a few more M5+'s too.
I knew Indonesia/Philippines was going to get a couple of doozies today.
The many M5's happening today along the left side of the ROF (ring of fire) may indicate a general similar energy/movement all along the plate being generated within a short space of time.
In saying this, I'm guessing such, it can be somewhat predicted that if one or a few M5's pop up along this line of the plate, you can almost predict that possibly (one, many or even all of) e.g. Japan, Kuril Is., Samoa, Solomons, Philippines/Indonesia, Fiji, Papua NG, Taiwan etc., will also be impacted.
But please remember, I am not an 'expert' in seismology.
So some (or many crazy ) of my predictions could be 'off'.

Haven't seen one there for a while.

Just as I thought the region between the Gulf of California and Chile is becoming more active.
Latest - Guatemala M5.3

Re: Earthquakes - 12/07/2012 21:07

As I predicted....the California region is getting up there with M4's and the regions around Turkey (latest M3.7) is rumbling and starting to 'throw up' a couple of bigger rumbles....and NZ with near M5's (M4.7's).
Have been out all day ('popped in' at lunchtime) tired so am only now catching up on what's been going on...will get back in a minute wink ..........

Kuril Islands just had an M5.6 (40kms deep)(near japan) as I had anticipated in an earlier post. I presume there will be a following tremour with a quake that size.
Posted by: duckweather

Re: Earthquakes - 13/07/2012 17:04

I could be very wrong here, as I have only had a quick sqiz at the EQ feeds - but get a feeling that Mexico/Guatemala may pop up with a moderately sizable EQ today.

Re: Earthquakes - 13/07/2012 18:46

In addition to what I said in last post, I feel that China will experience a large quake soon. Pressure is apparently building there.

Re: Earthquakes - 14/07/2012 15:53

Just as I was typing this - I was going to say that NZ was going to perhaps experience another quake - and it has.
The Kuril Islands will continue to pop up with M3 to M5 (+?), I feel , for a while yet. Every 10-12 hours or so, (very) generally speaking, there seems to come a 'run' of activity.
I feel that places like Samoa, Fiji, Japan, Taiwan, Vanuatu, PNG and NZ (the countries down the left side of ROF) will have potential for more EQ's today, given Kuril and NZ experiencing some more quakes.
Still have a sticking feeling about Mexico/Guatemala.
Argentina/Chile will continue to 'grumble', popping up the odd M5 (?).
I feel the Middle East may again throw up an M5 +, at some point. ? Afghanistan/Pakistan.
Again, though, these are just 'feelings' and please don't take these as 'predictions' wink

Posted by: duckweather

Re: Earthquakes - 15/07/2012 00:14

Looks like Turkey, Poland, Spain, Italy, Greece, Iraq areas will continue rumble and throw up the odd M4+.
The Canary Islands looks like it is starting up again - has been a little 'quiet' in last 48 or so hours.
Chile/Argentina/Peru areas will also continue to rumble, including the odd M4+.
California region will also continue to rumble, with spot quakes in a couple of surrounding US states (inland).
Left side of ROF will prob. pop up with M4+'s (seems to be a pattern).
Alaska will continue to 'rumble'.
Hawaii will occaisionally pop up with small 'rumbles'.
The country I am still watching is Mexico - leaning towards Guatemala.
All of the above are just feelings, as I have said in previous posts. The rest can be almost predictable patterns, going on current and past activity.

Re: Earthquakes - 15/07/2012 10:06

In a previous post, I mentioned I had a 'feeling' about Tibet and through to Mongolia (somewhere in these regions, and yes, this is a huge expanse of land) that something would pop up. I noticed that overnight that the top of India, below/right of the Tibetan Plateau, the Myanmar/India border region had an M5.6. This is getting close, creeping towards, to where I had a 'feeling' it would...given this EQ occurrence, I'm guessing there will be other 'rumbles' between there and Thailand, and there and Afghanistan/Pakistan....
The quakes along the out-to-sea ridges I also felt were a distinct possibility, but failed to mention last night.

Re: Earthquakes - 15/07/2012 20:03

The M4.5's near the Jan mayen region (north of Iceland) was a bit of a surprise today.
Told my daughter this arvo that the rock of Gibraltar region will see a small quake - and lo and behold - one occured some 50 minutes ago.
New Zealand has just popped up with an M4.1 (north island, near Taihape). So I am guessing they may end up with some more movement there, as well as possibly the islands of Kermadec, Samoa and Tonga. If a trend occurs there, you may see Kuril, Japan, Mariana, PNG e.g. pop up with some moderate quakes too.
As I have just got home...I'll be keeping an eye out for any other 'feelings', PE's (possible events) etc... smile

I was just about to suggest that Greece was possibly going to experience an M3-4, as I began typing this, and an M3 has just come up on the feeds.
The Kuril, Japan, NZ and PNG experienced some decent shakes overnight, correlating with that 'feeling' I had in my 2nd last post, last night.
Spain, Turkey, Syria regions may pop up with something to follow on from the latest Greece one.

Re: Earthquakes - 16/07/2012 13:35

Well...Kamchatka Peninsula, Russia just had an M5.4....now you're gonna think that I'm kidding here, I just got home and was going to note that I felt Kamchatka was going to be in for a sizable rumble. The feed beat me to noting this.

Re: Earthquakes - 16/07/2012 13:39

Just tried to edit/add info to above post, but can't seem to do it...
So, I was going to add that Kamchatka is just north of the Kuril Islands.
You could guess that the Kurils may also experience some moderate quakes as well (maybe M4/5+).

Been feeling Athens, Greece and Syria/Lebanon may be visited by some rumbles M4+. But...probably wrong (like Guatemala to date), my 'radar' has been tainted a bit today as I have had a cracking headache today crazy
Trying to regain my 'bearings'.
One thing I saw today (this is probably better for the weather section) was the strangest rainbow, south of Melbourne. It had no bend/curve and was very, very broad, from the ground to the cloud above. It didn't have all the colours of the rainbow either.... confused
Posted by: duckweather

Re: Earthquakes - 17/07/2012 09:19

Noticed that overnight Guatemala popped up with an M4.6 and has just had an M4.3 Honduras (near to Guatamala). As I said in previous posts, this region was niggling at me ('feeling') that they would experience some significant (significant because of the relatively shallow depth of the potential quakes) rumbles.

The Aleutian Islands (the islands which stream off to the west of Alaska) may receive another M4+.

Noticing that PNG has had a sizable M5.6, the 'surrounding' regions (maybe e.g. Fiji, Philippines, Tonga, Samoa, Kermadec and NZ) could experience further rumbles (M4+).

I also have a niggling feeling about Utah, US (and perhaps Oklahoma/Missouri). May not be substantial, but I feel that the US will experience more spot rumbles in their inland states.

Posted by: duckweather

Re: Earthquakes - 17/07/2012 13:07

very curious...I wonder if that colour spectrum (seemingly strange partial, straight rainbow) I saw south east of Melbourne, had anything to do with Moe's tremor today? Probably not..but it (spectrum) did leave me with a 'funny' 'feeling' after I saw it...or maybe it's my imagination, along with the ripper headache I had yesterday, running overtime. grin

Was just reading about the Washington (US) storms on another fave site. The lightning they are getting is humungous.
In relation to earthquakes, Washington has been getting M1's+.
I was wondering if these storms had anything to do with their tremors, given that plate movements, volcanoes, et., are not the only causes of tremors/quakes.

"I feel the Middle East may again throw up an M5 +, at some point. ? Afghanistan/Pakistan."
This what I had a feeling of on Sunday arvo. And as it has happened Afghanistan has had an M4.2.

The quakes of M4.4+ are interesting in the Sea of Japan, as they are not on land. I wonder if these have had an impact on the waters in this sea?

Re: Earthquakes - 17/07/2012 19:23

I also had a feeling this morning (mentioned in a previous post) that the Kermadec islands may see an M4+ today, and one has just occured there - M4.8. In addition to this I also felt that the 'nearby' islands of "Fiji, Philippines, Tonga, Samoa, Kermadec and NZ" may experience some more M4+'s as well.....will see if this occurs.
Posted by: duckweather

Re: Earthquakes - 17/07/2012 22:03

As I suspected, Kermadec has just experienced another quake - M4.7.
The regions surrounding Greece, Turkey and the south of Italy are quite active at the moment. I hope this is not an indication of a building to a larger quake.
I have had a 'sticking' feeling regarding Athens...but as always, I hope all people of the quake active areas are safe and any damage is minimal.

Re: Earthquakes - 18/07/2012 10:04

Got a few minutes to 'drop in' on WZ smile
The Chile/Argentina/Peru regions have become active again (is periodical). Peru may pop up with an M5+; Chile will continue to 'rumble'.
Interesting to see that the South East Pacific Rise had an M5.1 (west of Antofagasta, Chile). This movement (I am guessing) may correlate with movement in Chile?.
Sweden popped up with an M2.1 about 6 hours ago. There may be an odd small tremor pop up in the top if Finland, Sweden again or neighboring Norway. The nearby islands - Jan Mayen (due north of Iceland) may see a 'shift' as it did a couple of days ago. Just feelings smile

Re: Earthquakes - 18/07/2012 11:00

M's of 2.3,1.9 and 2.4 have registered in a line North of Koorda (north east of Perth) in farmland about 2 and 3 hours ago respectively.
I missed this earlier as was zipping in and out smile
With Melbourne/Moe having recorded a a couple of rumbles (which interestingly increased margenly in size from the first to the next - leaves me wondering that if there hadn't been this double 'release' of tension that there may have been another larger rumble which we had recently - the M5.3), we may see some more spot rumbles in Oz, maybe in Sth Oz and NSW - massive guess of course.

Just noting that Moe's latest M2.7 (1 hour ago)(fairly shallow at 3kms) is slightly bigger than the previous 2 tremors. One to 'watch' for further activity. Didn't think this was going to be the 'last' we felt of Moe/Melbourne's tremors.

The 'Fiji' quake of M5.9 was situated SE if Fiji and W of Tonga, at sea. Can't get any info atm on any tsunami possibility - don't know enough about it yet.
Posted by: duckweather

Re: Earthquakes - 18/07/2012 19:56

WA, north of Beacon, just had an M3.5 (depth currently registered as 0 [zero]kms) , north east of the other tremors today.
Posted by: duckweather

Re: Earthquakes - 19/07/2012 10:46

Just thought I'd add here, a little refresher of info from previous posts - saves those who may be watching this thread having to read back through everything...

I suspected that Greece (I thought maybe Athens) would experience a reasonably sized quake. Looking at the feeds with fresh eyes this morning, I noticed Crete had an M4.9. This is a little 'off' where I thought such may occur, but I had and still have a 'sticking' feeling about this region.

WA, north of Beacon, is still active with the latest M3.3. I feel there will be more to come - perhaps of the same magnitude'ish. I don't think we've seen the end of Melbourne's tremours, and may see a couple of other non-large ones in SA and NSW (Picton, Canberra????)

The ROF (ring of fire) is sporadically producing clusters of M4+ (countires involved include NZ, PNG, Japan, (Taiwan), Indonesia, Fiji, Solomons, Samoa, Tonga, Kermadec...)

Alaska's rumbles are starting to track inland. With rumbles and the odd M4+ popping up in the Aleution Islands (which stream off to the west of Alaska, south of the Bering Sea.

Chile, Argentina, Peru (down the west coast of South America) are consistently popping up with M4+'s and I feel this 'trend' will continue for some time.

The general area of California/Gulf, and occaisionally Mexico, Guatemala may produce less of the smaller type rumbles and a couple of the moderate M3/4+ types.

Chile, in general, may still 'see' a few M5's.

The US states inland may continue to pop up with spot tremors of an M2+ here and there.

Canada has been visited by a few smaller quakes, near the US border, and I feel they may see a couple of M2+ pop up inland as well.

The Middle East (Turkey, Syria, the top end of Iran/Iraq, Turkmenistan, Afghanistan, Pakistan and surrounding close countries) may see some odd rumbles, but I feel a couple of them will have an odd M4+.

Poland is still experiencing the odd rumble from the time I felt it was going to start getting tremors.

Spain might pop up with a bit of a surprise M4'ish and France (M2+?), Germany/Belgium maybe an M2.

The ocean ridges may pop up M4+'s occaisionally.

The African continent, has been 'quiet', with only one small quake at it's top coast in the last week.

Russia isn't showing up with much either at this time.

Norway/Sweden/Finland region have had a couple of small tremors, Norway/Sweden may see a couple more. These countries are due east of Iceland and the Jan Mayen Islands which experienced some sizable quakes in the last few days.

Anyway...I have added this post rather quickly between school and work activities...so I may have missed a few good points to add here.... wink

Just re-read my last post and I had said....

The general area of California/Gulf, and occaisionally Mexico, Guatemala may produce less of the smaller type rumbles and a couple of the moderate M3/4+ types.

What I meant to say was that the California region will continue to experience smaller/average 'rumbles', with the odd M4+ popping up.....and Guatamala, Mexico less of the smaller tremors (?) and tend towards more moderate quakes - M4+ sporadically.

Now that PNG has experienced a couple of M4.6+ quakes, the 'surrounding' islands may also have some moderate (M4+) ones.
The Kuril Islands/Japan/NZ/Indonesia may experience some moderate quakes as well....

Re: Earthquakes - 19/07/2012 17:35

Hi TheAnt.
Our M5.3 recently took us all by surprise a little.
It is definitely not a common occurence. In my many ( grin ) years, this was the largest I had felt. The last was some 40 years ago (have I possibly just given my age away grin ), when the arm chair I was sitting in was rattling strongly and moved a couple of inches (dang! showing my age again) across the floor. Pictures fell of the mantel piece, windows shook like the clappers and the cat disappeared for 24 hours. If I was to guess the magnitude of the one I just described, I'd say it was up-there with our recent one.

Just looked at the link for Wikipedia, which lists the more significant EQ's for Australia - Wikipedia

Re: Earthquakes - 19/07/2012 22:03

Hi GDL smile

When I was a kid, my father and I (and Mum), used to drive around the country towns in Vic.(and in Tassie and NZ) sussing out volcanic craters and regions. Gemstones/minerals/all things earthy; where they came from, how they were formed; volcanoes, earthquakes, geology, seismology etc., etc., weather events and the planets, just seemed to naturally fascinate me.
I have always been pretty intuitive, observant and 'tuned in' to shifts in nature (ok...really sounding like a flower child here grin ).
I am not always right with the 'feelings' I get about things, and am not a sensationalist, especially since talking about earthquakes in this thread, I am well aware that these natural events can adversly affect people, and am always conscious of that.

Like you, I really enjoy observing and learning about this stuff.
I am an amatuer with some of my book interests mentioned below and professional in a couple of others.
When I was a kid, my fave books were my geography/earth science/all things earthy (and the solar system), history, art and horses. Psychology and similar genre books made up the rest. And I still have all of those books - can't part with 'em.
I wish I had switched from the uni degree I was doing to earth sciences many years ago.

Re: Earthquakes - 20/07/2012 17:14

Yep...you guessed it...I was going to comment on the Kuril Islands substantial quakes. All M6+'s. They were moderately shallow too, which feeling these quakes would have been very reasonable in movement.
Japan may follow on with M4+'s, possibly even the Aleution Islands western tip may experience something too.
PNG, Philippines, Tonga, Samoa, Fiji, Indonesia, maybe down to NZ might also experience M4+'s too...will see.

Melbourne, near Yarragon and Mirboo North (not far from Moe) had two tremors, respectively, today. The ground is just slightly still vibrating.

Just as I was typing this the Japanese Volcano Islands have had an M4.9....and the North Atlantic Ocean, east of Venezuala an M4.8....

I felt that Canberra might feel a shake today (as I said in a previous post - yesterday)...well apparently some felt it in Canberra (the Melbourne M4.6) and reported it...as an M4. Sort of, nearly, just about, maybe close with that 'feeling' I had about Canberra.........
Posted by: duckweather

Re: Earthquakes - 20/07/2012 21:51

Hi Ken Kato wink

Yep, you are right. As I mentioned in an above post, Canberra apparently felt it as an M4. Interesting really, as the epicenter (just north of Mirboo North) was M4.5'ish, with a lessening in magnitude as the effects travelled north and north west, but somehow Canberra felt it as an M4......

The ground had been faintly rumbling on and off since the M2+'s today, till the M4.5...and after that too...
We may see some after shocks/tremors for a while.....

Re: Earthquakes - 21/07/2012 00:19

Just got back from being out, and have noticed that the Middle East, Georgia, Greece and surrounds have become more active.
I've had a persistant 'feeling' about a couple of these regions and seeing it increase activity doesn't surprise me.

China's M5 was interesting. My 'feelings' kept pulling me towards China, more towards the Tibetan region.

Fiji's 'now' M5.9 (deep 612 kms) I had metioned earlier as a distinct possibility when I saw that the Kurils and Japans Volcano Islands had some sizable quakes earlier. PNG through to NZ (maybe) could also see some movement of a moderate size too.

Posted by: Anthony Violi

Re: Earthquakes - 21/07/2012 10:41

Something certainly has to give sooner or later..Kuril Islands has been non stop with M5 quakes for weeks.

Duckweather i read somewhere a while back, cant remember where, that Russia was at risk of receiving a M8+ within 12 months. Have to see if if i can dig up where i read it..

Looks like we are going to see constant tremors here now, with a volcano developing in Bass Strait from now on these tremors will continue.

From the Adelaide Hills, through to Mt Gambier, then across to Gippsland, we are at risk of a decent earthquake. So its waking up, there has been talk of the western Victoria region of being overdue for volcanic activity for a couple of years now.
Posted by: duckweather

Re: Earthquakes - 21/07/2012 11:11

Good morning Anthony wink

Yeh... I read something too some times ago about Russia's possibility of a large quake. I'll have a squiz and see if I can find what it was that I read as well.
I know the China landmass is huge, but I am still drawn to the Tibet region for some reason. When China's quake occurred yesterday, it was getting close to the region (towards the lower part of Japan) I felt may feel a good old rattle. I am still drawn to the east of China as well, but the lower (SE) region, slightly inland).

Interesting about Bass Strait...I have been considering moving to Philip Island (again) or Tassie sometime in the future....or buying a small farm 'nearby' from the Dandenong Ranges/thru Wandin/into the Yarra Valley somewhere. Will postpone my 'feelings' and final thought on that one...love all of these regions.

In a previous post, I also felt that South Australia and the other regions you mentioned, will experience some 'rattles' too.

As I type this, I noticed that off the west coast of Oregon, has had an M4 (fairly shallow 10kms)....curious.

Just found this (report in 2009) re: Bass Strait volcanic possibility - interesting.
Posted by: duckweather

Re: Earthquakes - 21/07/2012 11:35

Well...the north west of China has just experienced an M4.5, the exact opposite of the region I felt may see activity...but it is interesting that some areas (regions) that have been a little on the quiet side are now popping up with some quite reasonable rumbles..

Re: Earthquakes - 21/07/2012 15:24

Well....New Zealand (as I 'felt' in a post this morning), east of Ruatoria (just off land) has popped up with an M6 (registered as M5.8 atm)...North Island.
This is quite a substantial shake, with a relatively shallow depth of between 12 and 20kms.
A quake of this size is not usually isolated to the one burst /shift of energy...so there may be more to come...perhaps not the same size...a freak of nature if it is bigger...

This quake is on the plate boundaries, so there could be reverberations/others popping up in surrounding countries/islands.

There is a possibility (a 'feeling') that Japan (and islands), Korea, PNG, Indonesia or Kurils may pop up with an M4+ ??? ROF (ring of fire)....
Posted by: duckweather

Re: Earthquakes - 21/07/2012 16:35

Just as I suspected/'felt', Vanuatu has experienced an M5.9 (mid range depth), following on from NZ North Island.

Re: Earthquakes - 21/07/2012 17:43

As I 'felt' and mentioned in my 2nd last post, the Kuril Islands (and the Marianas - which I didn't name before) are experiencing some sizable quakes.

Perhaps west of Alaska and correspondingly, the east of the Kurils may pop up with an M3 or 4+....

Out on a limb here, but Peru is 'niggling' at me atm...as is Afghanistan/Pakistan/Iran region...

Well Duck given that there was a 5.3 and a 4.3 it's not unlikely for aftershocks.

Re: Earthquakes - 21/07/2012 19:45

Yeh..it is pretty obvious...what I meant was the 'when' it could occur. We will experience more rattles.
As with the others that are occuring worldwide..it is 'feeling' when (and where) they may occur that 'twig' my 'feelings' for such.

Re: Earthquakes - 22/07/2012 11:37

Hi guys wink

I thought I’d summarize some of my ‘feelings’ (a word which I am using instead of ‘prediction’ – the two words are different in meaning) of where and when earthquakes/tremors were possibly going to occur recently (last week or so).
I have already summarized some of my ‘feelings’ (a few days ago for that moment in time) in the previous page of this thread, but for those who may only pop in for a look at this thread on it’s last page and want to catch up on or see what I have contributed (gabbled on with grin ) here; see below…..

Remember, I am an amateur, but keen observer nerd of seismology and am certainly not posting here in this thread (you probably think ‘painfully’ regularly sleep ) because I am a know-all smart alec. I pop in here and there (sometimes when I give myself some time off – I have the feeds on my screen constantly, while I do other things nearby).
I certainly don’t want to arrogantly hog this thread – it is for ‘all’. So tell me to ‘zip it’ tired if you are getting sick of me….

Summary of ‘feelings’ and actual occurrences;

*Indonesia to PNG, Tonga, Fiji, Kermadec, Samoa, Kuril, Japan/Islands regions M4+’s
*Taiwan the odd M4+
*Chile M4+’s predominantly and the odd smaller rumbles
*New Zealand M4+’s periodically, general pattern approx. every couple of days
*Alaska (mainland, sea port region) rumbling with more smaller than the odd M3+ - tracking inland, with the odd M4+ along the Aleution Islands – running to the west from Alaska
*Mexico/Guatemala The occaisional M4+ (including Peru a couple of times)
*The sea ridges – M4+’s – spot quakes, rather than clusters of smaller quakes
*California constant rumbles of M1+’s, odd M3+, with the latest M4+
*A couple/few of the US inland states would experience the odd M1+
*Canada region would experience a couple of smaller rumbles
*’China’ (my feeling tended toward Tibet) near Thailand western border
*Afghanistan/Iraq/Iran a few of moderate quakes
*Greece and surrounds (including Turkey) (sticking feeling of Athens) clusters with the odd M4+
*France the odd M2+
*Poland the odd/intermittent M2+
*Spain the odd M2+ and a less occurrence of and M4
*Melbourne the odd M2+ and the potential of an M4+ (on the day), with the under M1 rumble as they occurred
*Western Australia (after the M2+’s SW region) further M2+’s
*Gibraltar regions M4+

Missed observing (wasn’t watching) or failed to comment on;
*the Sandwich Islands
*the beginning of the Jan Mayen Islands moderate quakes
*might have only mentioned Hawaii once
*Italy only mentioned a couple of times
*England M2
*Puerto Rico region
And potentially some other places I can’t think of at the moment ….and I have got it wrong too sometimes…..

Some general patterns can be seen with some of the earthquake happenings and some pop up somewhat surprisingly…..

Cheers all wink

Go for gold DW. I for one don't think your hogging the thread & enjoy reading about your 'feelings'. My brother is in Nias near Banda Aceh right now, when he travels to the Sumatran region there is usually a sizable quake so I'm just waiting to see how well he's timed his trip this time.
Posted by: duckweather

Re: Earthquakes - 22/07/2012 13:05

blush Gee thanks Ms Milo.

I understand how you feel when your brother travels to these regions, but though there are many rumbles around the globe on any given day, many of them aren't likely to cause too many problems. Not all the larger ones will spark tsunamis and/or serious damage to person or property.

I feel that if 'you' (as I have) travelled to moderate quake prone areas, an awareness of the possibility of a quake and having a quiet plan of where you could go (e.g. higher ground or 'safe' places), just in case, can help ease worries.
Then get on and enjoy your 'trip'.

Cheers to you wink

Just got home and the plates (western side of the ROF) are grumbling again.
Watch for possible/potential 'happenings' in the Kurils, Japan's Volcanic Islands, ? western Aleution Islands, Philippine Islands, Vanuatu, Solomons, Mariana/Guam ... ???????

New Zealand Soth Island may grumble some more, and have a feeling about the North Island - north east of Gisborne (at sea)????

As far as the west coast of South America - maybe Nicaragua/Guatamala/lower Mexico and or Peru regions may come up a little later.???

The Middle East - Turkey/Syria/Iraq border region may pop up too.

Anthony (Violi)....I found a press release from the International Earthquake and Volcano prediction Centre ,dated 9th April, 2012, which you may have been referring to in your post. It is an interesting read...

Re: Russia

Also, if you click on warnings button on the left hand side of this web page (in link), you'll see they have added another warning as below;

2. July 1, 2012: Revised CGE Warning Notice 001-04-09-12 Is Issued.

A new CGE Warning Notice (CWN) has been issued for the predicted Kamchatka earthquake extending the warning period and adding an aviation communications warning.

Re: Earthquakes - 22/07/2012 21:57

Just as I 'felt' (Honduras) Nicaragua/Guatemala has come up with an M4.5,
- western Iran's M4.7 has come close to the region I suspected it may.
- the Japanese islands earlier
- the Solomons (forgot to mention PNG as well)

But there's a bit of a surprise in the Gulf of Aden, south of Yemen - M4.8. This is one of those surprise quakes I mentioned earlier. I didn't pick the potential occurence of that one.

Turkey is no surprise. I have often mentioned this region as one for possible moderate quakes - M4+'s

Posted by: duckweather

Re: Earthquakes - 23/07/2012 10:19

Those persistant 'sticking' feelings I had about Tibet were cemented overnight. Quakes ranging from M4.5 to M4.9 popped up.
My 'feelings' just kept tracking to this exact region.

Near Guatemala (near coast of Nicaragua) popped up with an M4.6 and an M5.0 as I aslo felt it would (a few hours ago).

I had been feeling that eastish of the North Island of New Zealand, at sea, there would be more reasonable quakes and just north of there (Kermadec Islands) have experienced an M4.5 and an M5. So not really in the exact region I suspected.
Posted by: duckweather

Re: Earthquakes - 23/07/2012 10:56

Just noticed PNG has experienced an M5.2. This quite a reasonably sized quake and fairly shallow at about 10kms deep. But the GeoScience Australia has pinned it as being only 1km deep - now that is shallow and could have casued PNG to really feel that one.

Maybe Indonesia, Banda Sea region, Solomon islands regions....may follow on with some moderate quakes too..

Meant to add that Kamchatka (north of the Kurils), the Kurils and Japanese islands may also experience M4+'s today.

Posted by: duckweather

Re: Earthquakes - 23/07/2012 11:14

Just as I also 'felt' last night/arvo, the western end of the Aleutian Islands was going to pop up with an M4+
Posted by: duckweather

Re: Earthquakes - 23/07/2012 17:19

The Aleution Islands (west) has certainly begun rumbling. I had a strong feeling it would.
Posted by: duckweather

Re: Earthquakes - 23/07/2012 17:52

At this stage, no tsunami is reported to have been generated by The Aleutian Islands quakes.

Back again, after a wee absence from here smile
Seeing that Afghanistan has popped up again with an M4+ is one of those regions, which if my fellow WZers have been following my gabbling on in this thread, would have seen it has been the spot that has had a 'sticking' 'feeling' for me....one of those regions I seem to be constantly drawn to as points of 'concern' for potential M4+'s.

The Aleutions have been a bit of a worry today, an yet another region I've been banging on about as far as my 'feelings' are concerned. This has been super active today.

Southern Greece has popped up with an M3+...yep...another spot I have been having persistant 'sticking feelings' about too.

So far I have been pleasingly 'wrong' about Samoa and Banda Sea today so far.

Re: Earthquakes - 24/07/2012 10:29

There have been some aftershocks last night near Moe and Melbourne. Assuming that people can't be bothered for reporting it because it just kept shaking for weeks and weeks. It tend to lead some major event? Like Christchurch or Indonesia?
Posted by: duckweather

Re: Earthquakes - 24/07/2012 10:55

Hi Mat...yeh I was aware of those..was monitoring the subtle tremors. If you were getting on with your day, busy, driving etc., you may not have noticed them in the suburbs away from Moe. I feel there will be another more noticable tremor soon.

Just a bit about the Sandwich Islands which have thrown up a couple of M4+'s recently - this is a small region dotted in an arc, with volcanos that have been active in the last million years. The reverse fault it is associated with, and which curves with the arc of the islands seems to be associated with its current activity. There may be some more rumbles there.

The Carlsberg Ridge, east of Ethiopia, which has popped up with an M4.7, may be where the Indian Plate and the Somalian Plate are spreading, apparently at a rate of 2.7cms per year.
I am guessing that this may see some rumbles pop up near Saudi Arabia south. Maybe even down toward Madagascar.
Posted by: duckweather

Re: Earthquakes - 24/07/2012 13:46

I've been flitting in and out and not paying much attention to what has popped up overnight or had much time to concentrate on the feeds. I said a couple of days ago that Canberra may see a tremor of sorts...well, though they felt Melbourne's recent M4.6, they have had an M1.5, south of Clive. Curious...see what happens there.....

Just got in again and was going to gabble on how I felt that the Philippines were possibly going to rumble again with a poss. M5 - they just had an M4.7.

Soooo....I'm feeling that Banda Sea region, or Taiwan, Mariana/Guam, PNG, or perhaps Kemadec, Samoa/Tonga regions...new Hebrides???? may experience some M3+'s.

New Zealand, I feel, may pop up with some M4+'s, maybe north east of the North Island and not sure about the South Island.

As always I hope I am wrong.

Alaska is till rumbling (not unusual atm), but feel that the Aleutions will experience another sizable quake/s.

Utah, for e.g., and some other potential inland US states may pop up with the odd M2+ (Tennessee??? Washington border with Canada???)

Hawaii will continue to rumble with M2+'s, as will the California regions.

I'll have to finish this off later...I am about to get a little annoyed with my keyboard!!!...it's goin'. I'm off to replace it..the keys are playing up frown

Back soon smile

As with the volcano thread, I have found an interesting newspaper article, dated 5th September, 1932, regarding a Melbourne earthquake, involving Bass Strait and the bayside suburbs (generally)...interesting read.
The heading is quite dramatic - though not unusual 'emotion' in those times surrounding such type events.

Right here's the rest - last bit of the 'run-down' from 2 posts earlier- before I was unkind (well...replaced) to my failing keyboard...

Mexico may experience and M4+, perhaps Guatemala region as well,
Chile may pop up with an M4+,
Poland may see an M3+
Turkey may see an M3+
The sea ridges (one or two) may pop up with an M4+

Some of the above have happened as you now in the last half hour or so....so, I've still put them up anyway as to what my feelings were earlier.... crazy

Posted by: Xavo

Re: Earthquakes - 28/07/2012 14:08

I guess unfortunately that's just the nature of the world we live in wink

Quite a lot of the earthquakes you're mentioning are located in or very near the Pacific Ring of Fire and also near major fault lines and tectonic boundaries. It's only natural that there's gonna be big quakes there from time to time.

Also my memory is sketchy, but pay some attention to the boundary between the Indian Plate and the Indo-Australian plate. Our lecturer was saying about how both were moving North (the Indian boundary into the Eurasian plate being the source of the Himalayas). Anyway, the Indian plate has pretty much stopped, or is coming to a stop (only just recently according to him), and it is now becoming apparent that the activity along the Indo-Aus plate is on the increase as ours plows into theirs. Basically, in my life time, that area is (one of) the next earthquake hotspots on this planet.
Interesting stuff when you think that both have been moving for millions of years and we are now witnessing the end of that.
Posted by: duckweather

Re: Earthquakes - 29/07/2012 11:49

Hi Xavo.

There has been some solid movement in the plates, and is not isolated to one particular region. Even inland faults are popping up with some strong activity in bursts or experiencing multiple/constant energy releases, like the California region; Italy/Greece through to Turkey/Iran/Iraq/Afhganistan general regions.
My feelings regarding PNG (last night) were unfortunately strong. I felt that the ROF west plate, at that region point, was going to 'give' quite substantially. This part of the connecting plates is on a 'fragile' bend/kink/edge.

A buoy near the Alaskan islands has sensed wave height variation/increase and is being monitored for possible tsunami (not large) affectation.

More in my diary, but will resist hammering this thread with it wink

They certainly were strong earthquakes Mat.

These quakes were very deep, so hopefully they won't have had as bad an impact as they would have if they were shallow.

Some of you might find this interesting;



California may just be in for a larger quake depending on whether the swarm of quakes continue, i.e. more smaller quakes releasing built up pressure is better than none and one big one.

Re: Earthquakes - 01/09/2012 10:09

Scientists say last year's earthquake in Japan has greatly increased the pressure of the magma chamber underneath Mount Fuji.

Based on the tectonic movements caused by the two earthquakes in March 2011, the researchers estimated about 1.6 megapascals of pressure, equivalent to atmospheric pressure of 15.8 kilograms per square centimetre, has been placed on the magma chamber.

Was in an 8.3 in Guam in the early 90's.
Mad stuff- concrete curbing rippling in a wave form with the amplitude perhaps 100 mm and a wavelength of 2 or 3 meters.

The main shock went for 60 seconds and threw me off the couch and onto my feet, which hardly touched the ground on the way out the door.

Filipinas screaming their heads off- cars jumping in the lot- two wheels off the ground on the bounce!

Over 100 aftershocks over 5 in the next 3 days - i was on the plane OUT of the place on day 4.

It sits on the marianas trench that island and you will see fossil coral benches on every hill top.

Re: Earthquakes - 12/10/2012 13:36

I was wondering how the NT would fare with this quake. Can you guess the magnitude of what you felt?
Melbourne (SW of Melbourne in Rokewood) experienced an M3.1 three hours ago.
One thing I've noticed about the recent SE of Oz tremors, is that they traveled from the SE of Victoria, up through to the NW, then into SA.
Now, they may be traveling from SA back down thru Melbourne towards the SE again...will see what happens.

Re: Earthquakes - 16/10/2012 11:21

Sometimes I think I am Ant crazy
The funny thing is when I have noticed these things, tremors are recorded in nearby areas of lower Oz and NW (Vic).
I do tend to believe though that the tremors registered SE of Vic have 'traveled' through to SA, and back again?? Or the reverberations of each tremor is subtly wandering through the rest of Vic......?
I have been sitting alot lately, thumping away at the keyboard writing my new book - so have been observing these tremors more than usual....gotta get out more? wink

Re: Earthquakes - 16/10/2012 20:57

Check out this link National Data Buoy Centre and click on the buoy (under Indonesia/Java - top right one of the two) showing 'movement' at the moment.
I've been watching this on and off today and it is registering a drop in sea floor surface (??) Initially, when the EQ occurred there the buoy register a rise and then the drop began.
This doesn't always mean tsunami, but I 'understand' that this buoy may be registering the 'distance' between it and the sea floor.
Someone please correct me if my observations are wrong.

Re: Earthquakes - 16/10/2012 21:22

The flashing diamond means the buoy is in event mode. 2 buoys in event mode..in fact? Any quakes in that region?

Re: Earthquakes - 16/10/2012 21:39

yes it is 'event mode' - I couldn't think of the name at the time of typing it - had a blank moment grin
There was an M4.3 there (approx 19.5 kms deep) at about 3am, Melbourne time today.

Magnitude Vs Average Annually

8 and higher = 1

7 - 7.9 = 15

6 - 6.9 = 134

5 - 5.9 = 1319

4 - 4.9 = 13,000 (estimated)

3 - 3.9 = 130,000 (estimated)

2 - 2.9 = 1,300,000 (estimated)

(Below 2.2 they cannot be detected by humans.)

So on any day there are thousands of earth tremors all over the world.

On a personal note I lived in PNG for over 10 years in the 1960's and 70's and experienced earth tremors on a almost daily basis and they aren't that big a deal after a while. Windows rattle, stuff falls of flat surfaces etc. The occasional big one every month or so that shifts you out of bed at night was the exception but really nothing all that exciting to write home about.

Put it this way if you lived under a highway overpass or within 5 meters of a railway track you would soon get used to the sound and vibrations of the occasional semi/train going over head and it is the same with earth tremors. Australians get up tight about them because they are rare here.

Re: Earthquakes - 17/10/2012 01:23

You must have felt around two-and-a-half- to three-thousand (or more?) earthquakes SBT in half the time that I felt my 100 or less.

My rough estimate of 100 is based on recalling feeling about a handful a year over two decades in another active volcanic region. I only remember things falling off shelves about three times out of that 100.

You must be some sort of earthquake magnet...

Good chart Ken, very interesting.
10 minutes before the Canada quake hit, I was showing my daughter the map where the Pacific Islands have had clusters of M5's today and said to her, "Across the Pacific here (Canada/British Columbia) is where I feel there will be a large movement, possibly an M6+, in the next hour."
Was not feeling too happy when it did occur.

Re: Earthquakes - 03/11/2012 23:08

I would love to experience an earthquake (only a weak one of course), just to see what it is like. I have never felt one before.
The closest I've been to an earthquake was when I was in the mountains west of Christchurch early this year, and they had a Magnitude 5 quake around 2pm that afternoon, with the epicentre near the city. But I was on the train at the time, about halfway back from Arthurs Pass (would have been approx 70kms from epicentre), and wouldn't have been able to feel anything abnormal on the train.
Posted by: duckweather

Re: Earthquakes - 03/11/2012 23:22

It can be an unnerving feeling.
Friends of mine, who live in Christchurch (and some other parts of New Zealand) are constantly experiencing tremors of varying magnitudes. Some of them have told me that they wish the earth would just stand 'still' for them to feel a sense of tranquility again. One of my friends houses is so cracked that she is thinking of moving.
I would hate to experience a big one, but the larger ones I have experienced (over M4) can leave you feeling a bit dizzy, head-achy etc. The last bigger one in Melbourne, before it 'hit', had a lot of people describing an initial shock wave (P), then the ground shake following. One of my dogs has become rather 'jumpy' whenever she hears rumbles from anything now.
Cheers, wink

Re: Earthquakes - 03/11/2012 23:25

Man, it's actually quite scary - even for a small magnitude quake - for your first time. I was lying in bed having an afternoon siesta (I was actually watching a Zombie movie) and there was this massive rattling noise, kinda like an approaching truck at full speed. Then the windows started clattering and the bed was shaking and the whole ground was shaking.
I ran outside when I figured it was an earthquake, and the dogs were wandering around very confused.

Not sure if tiled roof houses get the rushing noise, I'm pretty sure it's the tin on the roof shaking around that makes it.

Re: Earthquakes - 08/11/2012 09:42

An interesting observation, regarding the buoy near Guatemala, that before their big earthquake the buoy registered a diminishing depth from the sea floor to the sea surface level.
Now, in my non-scientific/non expert observation, could reading these 'levels' prior to a quake, be somewhat of a very short term predictor (time wise) indicator that plate/sea related quakes may occur? Just a thought.
I suppose one would have to be 'glued' 24/7 to observing all such buoys, which would not be realistic really.
Let's hope that the Guatemalan communities haven't been poorly impacted by this latest large movement. Though I do believe there have been some casualties unfortunately.
As I always say in my blog, I hope for safety and peace for all communities.
I've typed this while having a cracking headache, so hope I made sense.
Posted by: Xavo

Re: Earthquakes - 08/11/2012 10:56

What magnitude earthquake was it? I guess if the buoy was pretty much on top of area that sits on top of the subducted plate it could show a bit of a decrease in height. But I think by about that time the seismometer would've picked up the earthquake, or at least some of them.

Unless it was a massive time difference, then it probably wouldn't be worth the effort.

If you look at the location of the quake on the Global Incident Map, you'll see it is closer to Oz than Antarctica.
Anyways... crazy
Posted by: Xavo

Re: Earthquakes - 09/11/2012 23:34

I wonder if the recent spate of quakes centered around the South of Australia have anything to do with the Antarctic Plate becoming more mobile, or perhaps due to the slowing down of the Indian Plate, the Australian one is slowing down as well (although there'd probably be more activity in the Indian Ocean if that was the case).

I'm keen to start 2nd year Geology next year to get more into it.
Posted by: duckweather

Re: Earthquakes - 11/11/2012 10:31

Well Xavo, I am certainly no scientist and am just very much a lay person when it comes to what is actually happening with the 'shuffling' and general movement of the plates/ridges/trenches that is going on in the world atm.
Volcanic activity is having its effect on many areas too. Simultaneous volcanic eruptions and 'waking', I feel, plays its part or is somewhat associated with many quakes/tremors.
Many areas are 'active' atm, with energy being dispersed all over the place.
There are active volcanoes in the Antarctic currently and there is energy from plate movements which seem to be affecting the south of Oz. There is a series of ridge/plate/trench 'lines', a bit like a patch-work quilt running 'horizontally (of sorts) below Oz, reaching to Tassie and one runs up to approx below SA/Vic border. The recent larger quakes in the ocean were roughly in the central area where this 'bunch' meets. The second quake was more northerly (towards Oz) running along one of the trenches/ridges? than the previous one.
I feel we may 'see' some more activity from this cluster of 'joins' and in other places between Oz and the Antarctic in the near future.
But I am just an observer not an expert in tectonics. So someone on WZ may have more info on this stuff than little old me wink

Re: Earthquakes - 12/11/2012 10:56

Don't worry duckweather, nothing wrong with being inquisitive smile There's still things we don't know about quakes or only have limited knowledge about whereas with other aspects, we do know a lot about. One thing I've always been interested in is a perceived "clustering" of shallow big quakes occurring on different & geographically distant tectonic plates but within a small time scale of days... although admittedly, it's tricky to prove statistically beyond reasonable doubt and rule out subjective interpretation.

Speaking of which, yet another significant & shallow mag 6.5 quake just off the Guatemalan coast this morning (Mon) in addition to the big mag 6.8 quake in Myanmar aka Burma yesterday morning.

Posted by: duckweather

Re: Earthquakes - 13/11/2012 12:20

I am going to put my credibility of sorts on the line here and 'test' a hypothesis I have about possibly pre-empting some plate movement or other.
Ok here goes. The buoy S/E of Bali and halfway to Oz is showing increased water column 'height'/'depth'?. My amateur hyothesis is that this kind of change has preceded some of the other plate oriented movements we have seen. Could this current 'change' be a precursor to a plate movement/quake??
Will see if I am way off or possibly close.
Anyway, the Alaskan quake region was one I unfortunately being drawn to this week as a possible M3++?.

Theres nothing is happening at the moment here in the US. Being in Utah, as close to Toledo station, theres nothing felt or observed here at all. Media here hasn't got any report of this shake up. This probably seems fake, in accordance to make the 'end of the world' stuff looked legit.

You may have noticed that Beacon in Western Australia has come up with a tremor...but also have a look at the links in my previous posts (above) for Melbourne Uni's Earth Sciences seismo (now) and the LISS link. There seems to be activity in various places (in Oz, apart from other regions/countries).

Re: Earthquakes - 28/12/2012 23:38

Offshore of Western Australia, south west of Exmouth and north west of Carnarvon, has just experienced an M3.8 (20km deep).
This is very close to where I 'felt' (in my blog) one of this magnitude would occur.
It would be interesting to see if this is anything to do with the Indian Ocean plates changes.

Re: Earthquakes - 04/01/2013 13:48

For Melbournites, if you have just felt a small tremor, go to the Melbourne Uni seimo link in above posts.
Now, the wind here today has been blustery (to say the least), and at the time (last 20 mins) my cabinet got up a short, small rattle, there was no wind movement outside.
Will see if Geoscience note anything.

SE Alaska's M7.8 (between 10 and 28kms deep) has set off all of the buoys down the Aleutians and down to Canada.
I haven't had a chance to check any tsunami messages yet.
Now, some of you may think I'm a little strange at times, but I am feeling a little numbed by this quake - I 'dreamed'/felt last night that this was going to happen in this exact location and apart from the heat here keeping us awake, I couldn't get my mind to 'dislocate' from this feeling.
I had noted my feelings about this location in my blog yesterday (location and potential magnitude).
I hope this doesn't adversely affect this region - will check any tsunami warnings.

The WCATWC has issued a regional tsunami warning for it.


EVALUATION

SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE
BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER. FOR
THOSE AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT
OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME
THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN
CONTINUE FOR SEVERAL HOURS DUE TO THE CONTINUING SEA LEVEL
CHANGES AND RAPID CURRENTS. AS LOCAL CONDITIONS CAN CAUSE A WIDE
VARIATION IN TSUNAMI WAVE ACTION THE ALL CLEAR DETERMINATION MUST

USGS downgraded to 7.5, first big one of the year.

Quote:
The January 5, 2013 M 7.5 earthquake off the west coast of southeastern Alaska occurred as a result of shallow strike-slip faulting on or near the plate boundary between the Pacific and North America plates. At the location of this earthquake, the Pacific plate is moving approximately northwestward with respect to the North America plate at a velocity of 51 mm/yr.

This earthquake is likely associated with relative motion across the Queen Charlotte fault system offshore of British Columbia, Canada, which forms the major expression of the Pacific:North America plate boundary in this region. The surrounding area of the plate boundary has hosted 8 earthquakes of magnitude 6 or greater over the past 40 years; In 1949, a M 8.1 earthquake occurred close to the Pacific:North America plate boundary approximately 230 km to the south east of the January 5th earthquake, as a result of strike-slip faulting. In October of 2012, a M 7.8 earthquake occurred approximately 330 km to the south east of the January 5th event, slightly inboard of the plate boundary, and was associated with oblique-thrust faulting. The latter earthquake was likely an expression of the oblique component of deformation along this plate boundary system. The January 5th, 2013 earthquake is related to that Haida Gwai earthquake three months previously, and is an expression of deformation along the same plate boundary system.

Check out the seismographs from various places on the planet which responded to the Alaskan earthquake yesterday -
Heliplots/seismgraphs

Also, if you are keeping an eye on the Melb. Uni seismos in Gippsland and South Australia, there has been regular recordings 'going off' with them as well (for local activity) - Melb. Uni seismo
This seismograph gives a 'picture' of a current 60 minute time frame. What is out of view now is a movement (Gippsland) which occurred over 60 minutes ago, which sent the 'needle' almost off the charts. If you have a keen ear, you can hear like a faint underground thunder as it passes through.

The Carlsberg Ridge (central Indian Ocean) is currently 'experiencing' multiple earthquakes of an M4+ magnitude. This is close, if not on, the region where the plates have apparently 'clashed' and been damaged.
Simultaneously, the Aegean Sea is experiencing multiple quakes from M2 upwards.

SE Victoria (Berwick) and Bass Strait (off the northern coast of Tasmania) have come up with tremors (M1.8 and M3.4 respectively) both at a relatively shallow depth.
I've been noting my persistent feelings (blog) for these locations for some time now, with a particular drawing to the Tassie location.
Have been observing subtle ground movements and (you'll think I'm crazy ) some deep underground tones as well. Not panic material, just interesting.
Anyways...I am sure South Australia and Western Australia (at least) have had a couple of small tremors too (helicorder and other seismo readings), but haven't shown up on the Global Incidents Map

Also; NSW, Frogmore, has had an M3.2

Noticed this and the volcano topic today and it's re ignited my interest, pardon the pun. Always been interested anyway, rather rusty tho!

Hi BlueMoon.
Can I be the first here to welcome you to WZ and this thread.
I may seem to hog the thread here just a little bit, but it is an interest of mine. I am a complete amateur regarding seismology, so your experience in this area will be appreciated by me and many others here, I am sure.
I also need to pick my cousins brains a bit more too (he is a seismologist), but unfortunately I don't see him much, as he trots around the globe a fair bit, Switzerland etc..
Anyways, cheers to you and I'd like to know what you think of the activity on Leon's seismograph I've been gabbling on about smile I've got a bit of a feeling about it, but I'll 'sit' on my thoughts for now.
Best wishes, Duck.

Re: Earthquakes - 13/01/2013 19:43

Welcomega to Weathzone Blue Moon!

Was reading on ABC that a local Tasmanian seismologist put the Tassie quake down to the Australasian plates northwards movement and a build up of stress associated with that movement.

But I wonder if there's any association with the Australian Hotspot which is somewhere in that area (in the strait I believe).
Posted by: BlueMoon

Re: Earthquakes - 13/01/2013 20:02

Hi Xavo, thanks for the welcome. I can see I have to swat up on Aus geology haha. Ummm, it's possible there's a link between the hotspot and the earthquakes, but normally they're more plate movement related.

I'm just about to start second year Geology with a dual degree of Geography.
Have you got any good books to recommend?

Re: Earthquakes - 14/01/2013 11:29

Xavo I did Earth Sciences in NZ 30 years ago...makes me an old timer now haha. It was a broader degree than geology and my interest was in palaeontology and plate tectonics. Worked for a while with coal core sampling then had kids smile Where are you studying, and is it seismology? Can't help with books sorry, you're more up to date than me!

Hey Xavo....I found an article from The Age from 2009 regarding the HotSpot you were talking about.

I am sure there is a later dated article about this region, but I'll have to go through my clogged files to find it. I'll post it for you if/when I can 'dig' it up.

Well, I dug up a fascinating newspaper article (from a site I can get a little obsessed with on occasions grin ) from the Argus Newspaper of Melbourne, dated 4th July 1885.
The article is about The Earthquake which rattled Melbourne at that time.

Re: Earthquakes - 18/01/2013 19:53

Now, before you read what I'm gonna say below, many people today and back to ancient times believe in the following;
If you look at the Melbourne sky currently (and for the last hour or so) you will see it is riddled with (laymans terms) ribbed clouds. To some this is a sign of (or precursor to) an earthquake/tremor.
Now....I keep an open mind regarding the presence of these cloud formations...and an 'on the fence' as to whether they are just a natural phenomenon due atmospheric/wind conditions or maybe signs of "geomagnetic" disturbances.
Within one section of these clouds I thought I saw a horizontal 'rainbow' as well.
So Daffy Duck (me) is prepared to be 'advised' by the knowledgeable WZ's here as to their opinion on these cloud formations. I'd like to know what y'all think wink
Posted by: TheAnt

Re: Earthquakes - 18/01/2013 23:32

I assume you mean Cirrocumulus clouds: If there are only small patches of cirrocumulus and perhaps some wisps of cirrus, it usually means a continuation of good weather and if it is seen after rain it usually means improving weather.
No I do not believe it has anything to do with that. As you posted this around he time the sun is lowering in Melbourne I assume the sun inter racted with the ice crystals at the right angle creating those 'special effects'. High clouds do this very often.
http://en.wikipedia.org/wiki/Circumhorizontal_arc you can also read this as for your sighting of a fire rainbow type of thing.

Re: Earthquakes - 19/01/2013 07:22

Thanks Ant.
I took photos of all the formations I saw yesterday. Apart from being like a kid with a new toy with practicing with my new camera ( grin ), I was interested in (and curious about) the huge spread and shape/structure of these spectacular clouds, so I took some pics. Just need to upload them to the computer now.

Anyway, currently compiling a new blog post and have noted the seismo activity on my two (local) favourite sites (links in above posts). Also watching various helicorders when I can.
There has been subtle activity, from what I can see and have noted, in Melbourne and elsewhere in Oz. Geoscience has only recorded two notable tremors in the last 7 days....?

Hi TheAnt.
Yep the west coast is quite an active zone. What I meant by "February may be a busy time for quakes/tremors, I feel." is that worldwide, not just the US west coast, may experience a busier period of tremor activity. (If that's what you were referring to wink )
Heightened volcanic activity is going to add to the mix - with bumping up the number of tremors felt in many places.
It is going to be an 'interesting' and 'busy' year I feel.

Santa Cruz Islands have been experiencing an incredible number of larger quakes recently and just now an M6.7. This latest quake has set off the buoy nearby - which is reading a 1 meter difference in height/depth of the water column.
This is, unfortunately, one of a couple of areas which I felt were going to be hot-spots of increased (magnitude size) tremors.
Lets hope (with limited knowledge of this last event, so far) that the island communities in this region are not being poorly affected.

Re: Earthquakes - 02/02/2013 10:17

Admittedly I don't quake watch too closely, but I have noticed in the last few days there have been an awful lot of quakes between magnitude 5 and 7. Solomon Islands, Alaska, Chile.. It seems to be a lot more than usual anyway, is this a prelude to something quite a bit more significant do you think? Curious.
Posted by: duckweather

Re: Earthquakes - 02/02/2013 10:20

Now...if I am reading the buoy (second buoy to go off) reading correctly, in the Coral Sea - near Australia, the buoy sensors read a short spike in height/depth of the water column before the quake struck...interesting. Could this be read as a precursor (albeit minutes) before the quake struck. Though, the challenge would then be (and painstaking), if we were looking for such precursors, to be intently watching all buoys for such pre-movements.

Hi Edgeofthestorm, The movements we are witnessing in the Pacific (east, west and in-between) are possibly displaying (in my amateur observation) a definite unrest in the plates. The Indian Ocean plate disruptions may continue as will the effects of volcanic activity around the world. The 'energies', however, all generally intertwined and somewhat related. The deep magma movements are moving energies all over the place and 'venting' in many places at the moment. The Kamchatka 'peninsula' in Russia is a good example - many of its volcanoes are simultaneously erupting, producing rivers of lava, no seen so voluminous before (to my knowledge).
I feel there are more larger movements to occur in 2013 as our planet continues to disperse such 'energies'.

Re: Earthquakes - 03/02/2013 02:02

Well you'll probably think I'm truly strange mentioning this, but (it is currently 1.55am here) I woke up suddenly a moment ago, after a 'cold' feeling of a larger EQ in Japan. I checked the feeds and to my 'shock' discovered Hokkaido (which I had mentioned as a particular area of 'feelings' I had for a larger quake - in my blog) has experienced an M6.9 (moderately deep) over 30 minutes ago...
Hope the communities there are ok. Will check more on this in the later morning.
Posted by: duckweather

Re: Earthquakes - 03/02/2013 09:42

Japan Today has a good, concise article about this mornings quake in Hokkaido.
Very interesting how the region broadcast, via TV and radio, a pre-warning about the oncoming quake for the communities....enabling them to get out of some of their buildings and maybe attempt reaching higher ground, and so on.

Also, have a look at the interesting reading from the buoy number 52406 , still in active mode near Australia.
Posted by: edgeofthestorm

Re: Earthquakes - 03/02/2013 10:17

Thank you for your explaination, duckweather. I'll keep watching with interest. With more quakes in the Solomon Islands, and now Japan, things are very active indeed. Looks like an interesting year is ahead..

Re: Earthquakes - 03/02/2013 10:56

Cheers, edgeofthestorm wink I am an amateur observer, but very interested in the physics, chemistry and overall science of things. I tend to go on my intuition mainly, mixed with some knowledge of science. Not an expert by any means smile

Just regarding the 'energies' I mentioned above, this energy fluctuates,transfers, increases/decreases, alternates and so on. I feel this is one reason why we see 'clusters' of larger tremors, sometimes, on one side of the Ring of Fire, then an appearance of a 'cluster' of larger EQ's on the opposite side of the ROF (as an example of a 'zone') at a different time. Plate 'Push/pull', plate drift, sea-fore spreading, magma movement, weakening of 'points', and so many other 'things' influence (cause) all the EQ's/tremors happening.
Cheers, Duck.

Re: Earthquakes - 04/02/2013 11:07

The Santa Cruz Islands earthquakes have been relentless recently, which is a bit concerning, leaving you to wonder when it'll all settle or what the 'end' result is going to be.
As I type this, it is all 'quiet', which I find 'interesting', but also feel like I'm waiting for the next movement. Actually, worldwide the earthquake activity has 'quietened', which also leads me to feel that this is a momentary lull in movements.
I'm trying to find the article I saw in the last couple of days which perfectly describes what is happening around the Santa Cruz Islands.
The energy expended up till now, in the west of the Pacific, has been incredible. But I feel it will rev up again in the next 24 hours (if not sooner) (Note: don't take what I say here as precise 'predictions' - I could be very wrong).

Ahh, just found one of the articles I was referring to above re: Santa Cruz Islands and plate activity

Re: Earthquakes - 04/02/2013 12:12

An interesting site to visit, which maps the latest earthquakes and volcanic activity is Volcano Discovery
Have a look at how many volcanoes are 'active' at the moment. Also zoom in on the region of the Santa Cruz Islands - many of the quakes are very close to the Tinakula volcano, which is in "minor activity or eruption mode" at the moment. The volcano is steaming and maybe 'spewing' some ash.

Hi Gazr.
It was rather strange yesterday/last night. I was 'talking' to a couple of people in the U.S. last night, and they also observed some odd things with the same EQ feeds. There was even the same 'chat' about this going on other forums too.
Some thought it may have been because of hacking or ?
The USGS site could be visualized yesterday (you could get the site up - yes) but the list of tremors 'fed' out from their site was nothing for a while and a trickle till now. It appears that a 'number' of EQ's have been 'back-dated' now.
Some of 'comments' on some sites have been that their have been many more tremors (in the U.S., for example) - in that time - but have not been 'fed' out.

AN EARTHQUAKE HAS OCCURRED WITH THESE PRELIMINARY PARAMETERS

ORIGIN TIME - 0112Z 06 FEB 2013
COORDINATES - 10.9 SOUTH 165.1 EAST
DEPTH - 33 KM
LOCATION - SANTA CRUZ ISLANDS
MAGNITUDE - 8.0

TIME - TIME OF THE MEASUREMENT (Z IS UTC IS GREENWICH TIME)
AMPL - TSUNAMI AMPLITUDE MEASURED RELATIVE TO NORMAL SEA LEVEL.
IT IS ...NOT... CREST-TO-TROUGH WAVE HEIGHT.
VALUES ARE GIVEN IN BOTH METERS(M) AND FEET(FT).
PER - PERIOD OF TIME IN MINUTES(MIN) FROM ONE WAVE TO THE NEXT.

NOTE - DART MEASUREMENTS ARE FROM THE DEEP OCEAN AND THEY
ARE GENERALLY MUCH SMALLER THAN WOULD BE COASTAL
MEASUREMENTS AT SIMILAR LOCATIONS.

EVALUATION

SEA LEVEL READINGS INDICATE A TSUNAMI WAS GENERATED. IT MAY HAVE
BEEN DESTRUCTIVE ALONG COASTS NEAR THE EARTHQUAKE EPICENTER AND
COULD ALSO BE A THREAT TO MORE DISTANT COASTS. AUTHORITIES SHOULD
TAKE APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS
CENTER WILL CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE
EXTENT AND SEVERITY OF THE THREAT.

FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT
OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME
THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN
CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL
CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE
ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

TAKE APPROPRIATE ACTION IN RESPONSE TO THIS POSSIBILITY. THIS
CENTER WILL CONTINUE TO MONITOR SEA LEVEL DATA TO DETERMINE THE
EXTENT AND SEVERITY OF THE THREAT.

FOR ALL AREAS - WHEN NO MAJOR WAVES ARE OBSERVED FOR TWO HOURS
AFTER THE ESTIMATED TIME OF ARRIVAL OR DAMAGING WAVES HAVE NOT
OCCURRED FOR AT LEAST TWO HOURS THEN LOCAL AUTHORITIES CAN ASSUME
THE THREAT IS PASSED. DANGER TO BOATS AND COASTAL STRUCTURES CAN
CONTINUE FOR SEVERAL HOURS DUE TO RAPID CURRENTS. AS LOCAL
CONDITIONS CAN CAUSE A WIDE VARIATION IN TSUNAMI WAVE ACTION THE
ALL CLEAR DETERMINATION MUST BE MADE BY LOCAL AUTHORITIES.

ESTIMATED INITIAL TSUNAMI WAVE ARRIVAL TIMES AT FORECAST POINTS
WITHIN THE WARNING AND WATCH AREAS ARE GIVEN BELOW. ACTUAL
ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE
LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN
SUCCESSIVE WAVES CAN BE FIVE MINUTES TO ONE HOUR.

Only just got in from driving all over the place since 9am...just the thing to be doing on a stinking hot day! Only just learning of the situation with Santa Cruz Islands.
Santa Cruz's situation doesn't surprise me, most unfortunately. I had a horrible feeling that the next immediate movement in this area was going to be very substantial.
I hope to goodness the surrounding island populations are OK.
Off to read more about this now....

Absolutely agree with you ... it would be great if WZ somehow stored the images associated with events (like radar / soundings etc) as well.

But it may be smart to create an event specific (technical?) thread if the event is significant, this thread is pretty much well for general discussion and I'm sure the intent is not to clog it up with dozens of pages on one single event (if it is significant).

Depth 10.1km
Time 4.35pm (Brisbane time) / 6.35am GMT
Location 10.78S 165.61E (near the Solomon Islands)

There have been at least 37 earthquakes/tremors in this area today

Re: Earthquakes - 06/02/2013 18:13

This is one of the better (info wise) articles, from the Santa Cruz Sentinel (United States), which I have been able to find so far.
There have been some lives lost and communities, some badly, affected by tsunami waves.
The EQ's are continuing and may not let up for some time. The M8 quake earlier, resonated almost world wide. Seismographs in many countries globally recorded some substantial movements on their equipment.
If I find any other quality info, I'll jot it here.
Posted by: duckweather

Re: Earthquakes - 06/02/2013 22:09

The quakes in and near Santa Cruz Islands are fluctuating in size and I am feeling that another large quake may occur again. This area is appearing to be very unstable and unpredictable.
I am wondering what it is doing to the sea floor. I read somewhere that a previous large quake (years ago) raised a reef in the region 10 metres. If I can find this report I'll post it here.
This quake series is apparently some serious subduction activity.
Posted by: Steven

Re: Earthquakes - 07/02/2013 19:58

More aftershocks in the same area overnight and during today, but none were large enough to trigger a tsunami advisory/warning. There may have been 50 earthquakes/tremors in this location since yesterday
Posted by: duckweather

Re: Earthquakes - 07/02/2013 20:54

Yes Steven, this relentless movement is quite incredible.
I found an article about this series of quakes and the science of seismology (not a long article) - Recent major earthquakes show underestimated potential for "Superquakes"

I believe (and have said for a long time now) that 'we' are in a new age of enlightenment regarding the science of tectonics.

Cheers, Duck.

Re: Earthquakes - 08/02/2013 09:55

I'm guessing that some of you guys might be feeling similar to me when I say I feel a bit sick in the stomach watching the poor Solomon region relentlessly experiencing all of these quakes.
When Christchurch's multiple quakes were happening, I felt the same way. I know how unsettled my friends were in Christchurch at that time, and I can only guess that the island communities in the Solomons region must be equally perturbed by what's going on there.
Imagining the forces at play here must be tremendous and I can only hope to goodness that it will settle down soon. I've lost count of the number of earthquakes this region has/is experiencing.

Re: Earthquakes - 08/02/2013 22:40

The USGS also has the shake map listed as an "IX - RED" - this is the second highest on their charts frown
If there isn't a tsunami of sorts generated by this one, I would be quite surprised.

Re: Earthquakes - 09/02/2013 07:40

Upon getting up this morning, I was hoping that the EQ activity in the Solomon/SC Islands region had maybe begun to settle somewhat. But this hasn't occurred.
My heart goes to the island's peoples being poorly affected (even live's devastated) by this gobsmacking series of quakes (the tsunami etc.).
That 'sick in the stomach' feeling I mentioned yesterday, regarding witnessing this change/movement happening there, hasn't gone. This is the area I have been most drawn to, for months, as being one of potentially some very serious EQ activity.

Depth 27km
Time Sat Feb 9 at 1.26am (Brisbane time) / Fri Feb 8 at 3.26pm UTC
Location near 10.91S 165.96E (near the Solomon Islands)

This did not trigger a tsunami advisory/warning

More aftershocks continue near this location
Posted by: duckweather

Re: Earthquakes - 09/02/2013 22:58

If you have looked at the Global Incidents Map - Earthquakes your eyes might be bugging out at the number of quakes down the east coast of both islands. But it looks like there is a glitch - the depths are nearly all zero, and as far as I can tell, NZ hasn't experienced all of these quakes today.
It's good to see NZ registering on the Global Quakes Map, so that 'we' don't have to look at multiple sites for info.
NZ experiences various quakes each day, but the scenario showing up today on the Global Map is apparently not quite right crazy

The Melbourne Uni seismo's have been picking up ground movement in Gippsland, particularly over the last 24 hours. The EQ in Indonesia just now may add a little to the current movement though.
The Uni's South Australia seismo has also been picking up movement yesterday, but for both Vic and S.A nothing has come up on GeoScience yet.
My daggy seismo is also noticing some mild movement too since yesterday.

Re: Earthquakes - 17/02/2013 09:30

Just realized that when this comment is posted, 'duckweather' looks like she is hogging the posting in the "General Science" list of WZ... blush (apols)

Anyway, many of the larger quakes very recently have been quite deep, which I find quite interesting.
Prior to this last group, many of them (for example, the Santa Cruz Islands' quakes) were mostly shallow. Makes me wonder if some related and 'uniform' movement has been carrying on below - meaning some firm shifting (for want of a better word) happening in the crust...effects on volcanoes?
I get a wee feeling there may be some more significant earth movements to come, including more M2+(ish) popping up in Australia.....
Posted by: duckweather

Re: Earthquakes - 18/02/2013 21:50

NSW (near Orange) has just had an M3 (an hour ago) and very shallow depth (0kms according to Geoscience).
As I said in my last post, I felt that Oz would come up with M2+'s, shortly after all of the larger quakes in the ROF in the last 24 hours.
The was some faint movement in Vic too - only picked up on seismos and there was a very small movement west/east or east/west (horizontal) too.
I've got a very mild feeling that Vic may come up with something (M) soon in the eastern part of the state - between Melbourne south/east side, along a sweeping curve (U) to the NE most point of Vic, or somewhere on a direct line from Phillip Island to the Kosciusko National Park (NSW). (But remember - I could be wrong - this is just a feeling, not a prediction) wink

Just a recap of the last 7 days for tremors reported on the GeoScience website -
Western Australia, South Australia, Victoria, Tasmania and New South Wales have all recorded several M2+(+)'s.

The seimo's on Melbourne Uni's and Leon Mow's websites are recording current movements, which may be (Leon's particularly) recording reverberations from Santa Cruz Islands earthquakes - which have revved up again in the last 14 or so hours.

Peru is currently experiencing multiple earthquakes in the M5 region.

Just thought I'd a few more EQ links to the above ones I've mentioned.
Many of the NZ tremors don't show up on the Global Incidents Map = Earthquakes

Geonet quakes New Zealand

South Australia - recent tremors

Australian EQ News - eastern states

European/Medditeranean

Current PSN Seismicity - including US states and Australia

British Isles This appears to not be showing the very latest movements (last 36 hours or so)

LISS - worldwide heliplots

I'm sure I've got some very specific regional (in various countries) links in my 'files' somewhere. When I find them, I'll add them too wink

The east of Timor just had a near M6 (varying readings of depth from 35kms to 80kms)...I am guessing our friends in the Northern Territory (particularly Darwin) may have felt that one too?
Our Melbourne seismos picked it up quite distinctly.

Re: Earthquakes - 24/02/2013 08:43

Ok..some of you may think "whatever" or "get a life" Duck grin ,but anyways - I noticed subtle ground movement in my daggy seismo and on Melb. Uni's seismo in the hours before Melb.'s SE M2.6 (near Moe) at about 2am this morning. Call me strange, but I could also faintly here 'rumbles' here and there (or was it one of my son's friends 18th's 2 suburbs away poke )
I had a gut feeling something was brewing for the SE last night, and actually thought it was going to be more of an M3+?

Simultaneous EQ's of Alaska and Hokkaido, Japan of M5+'s.
Alaska's is in the northern end of the ocean, SW of the Gulf of Alaska - can't make out an undersea volcano or a 'crustal' or trench (etc.) join atm - very curious.

Both quakes at same depth apparently.

Re: Earthquakes - 25/02/2013 12:11

Very curious...the Global Incidents map has one of these quakes registered near Alaska and nothing (at the moment near Japan), and another global EQ map has both earthquakes east of Japan in a similar region and nothing near Alaska...????

Re: Earthquakes - 01/03/2013 10:31

The quake in the Kuril Islands, 9 hours ago, has so far not been followed by aftershocks. This a similar occurrence to the one in South America recently (also an M7).
Interestingly, before the Kuril's quake was registered with various agencies, three buoys along the Aleutian Island chain (middle to the west of), went into event mode (and are still so). A minor quake occurred on the Aleutian chain, but I would have thought (to my limited knowledge) not enough to have set 3 buoys off. (it had me thinking that the buoys may have been registering sea floor movement before the quake???)
This quake was fairly shallow at between 50 and 60 kms, and no tsunami watch or alert was raised.

For our South Australian friends, check the link I put in a previous post for the tremors which have been pooping up in your state. There have been a few.

Santa Cruz is still being rattled intermittently, and I get a gut feeling that during March we may see another larger quake there, and another substantial EQ involving the Ring of Fire.

Also I get a feeling that we may see a larger inland quake in a region where the buildings are not earthquake safe (Mediterranean, Middle East..????).

Anyway, I will compile another EQ post for my blog when I get a chance.

Cheers, Duck.

Re: Earthquakes - 02/03/2013 09:24

Just re-read my last post.
Dear SA, you are not "pooping up" with tremors atm. blush grin My goodness - you would have some uncomfortable issues if this was actually happening for you.....
My friends, instead you have tremors popping up here and there.

Anyway....The Kuril Island region has come up with 'aftershocks' - big'ns.
But here's something I am sometimes left wondering.....Many a time the word/s "aftershocks" is used to 'explain' the expression/occurrence of a subsequent ground shake. Sometimes these movement are larger than the previous one. When this occurs, some say the previous (smaller [though moderately sized]) one was a fore-shock.
But I sometimes feel that in some circumstances, the related (by location) quakes can actually be 'new' events and not actually an after-niggle of the same/exact disturbed location. Though one movement in a plate/fault can trigger a neighborly agitation.
Obviously tremors/quakes and movements can also be caused by other irritation bodies, such as volcanoes, magma movements/migration, meteorite/asteroid impacts, gas and other 'substance' disturbances etc., and I feel (without proving this yet) that the Kuril's quakes are possibly volcanic related (as well as plate).

Cheers Duck....

Re: Earthquakes - 08/03/2013 01:57

Heard on the radio (havent checked geoscience - net is down) & it appears there was a tremor (2.5) off the coast of Newcastle ~1130 on thu 7/3 at a depth of 22km. Didnt feel anything here, not that I would expect to given its small magnitude!
Posted by: duckweather

Re: Earthquakes - 08/03/2013 07:53

Hi Grant,
Yep, you're right. If it had been shallower again, say 0-10kms deep, you may have felt a slight rumble (just guessing), and perhaps if it was more on land. But that's not to say no-one felt it maybe.
If you look at the "last 30 days" of the GeoScience records of tremors on Oz, it is interesting to see there are some spots which experience quite regular trembles. Then you get some areas that crop up 'out-of-the-blue'.
If you ever think the ground is moving, but are not sure, put a glass of water on a firm surface, where there is no disturbance from anything else moving (preferably for quite a distance - at least a few hundred metres from roads etc., for example), and look for ripples and sways in the water's surface. Sometimes I've picked up on tremors before, during and after they occur, that way. You can also sometimes pick up vibrations from EQ's in the Pacific and elsewhere.
As far as my daggy seimo (other gadget) is concerned - back to the drawing board, as my cat, Krazy Kelly, trashed it.
Cheers for now, Duck wink

Love your work but anything on a site called "The Extinction Protocol: 2012 and beyond" surely has to be taken with a grain of salt. Nice to see the 'and Beyond' but - assume it was added when the world did not finish on 21/12/12 smile
The world is a constantly moving and changing living planet - as such then for sure it will continue to evolve - earthquakes happen because the plates are moving - but pseudo terror stories like that one do little IMHO to actually move an intelligent debate forwards.

I always maintain an open mind with anything that is written or described in the media, internet etc..
There are so many curious articles 'out there' that one may not find in the mainstream media, and I read them then make up my own mind what I make of them.
And yes, the world is constantly changing and always will. But there are times when the physical aspect of our planet throws up some interesting events. When one reads through the various interpretations of these events, there can be some stunning reminders or confirmation (or new info) as to how vulnerable we can be to Mother Natures' behaviour and the implications for us.

Thankyou for saying your like the stuff I mention here. I wish I had more time to devote to educating myself more about the sciency aspects of this planet/EQ's. Actually I wish I had changed from one Uni degree to a science one many moons ago. I'm just a happy amateur. wink

A bouy east of Kamchatka Peninsula, western 'arm' of the Aleutian Islands, Alaska, has registered a 2 metre drop/variance in depth/height of the water column/sea floor. (EQ yet to occur, or to be reported)

Re: Earthquakes - 11/03/2013 22:36

Tennant Creek (nearby) just had an M3.5 (33kms deep).

PNG has had a cluster of M4+'s today and an associated M4+ in the Santa Cruz Islands region. This general region is still on the move and I feel there is more to come (as I have previously mentioned). I still get a gut feeling that this area may see an M5++? this month again, perhaps causing sea level disturbances.

Another region I get a gut feeling may experience a substantial movement is Japan (coast).

The Australian mainland may see some more movements in relation to the plate/volcanic issues north of the continent (a feeling only).

Re: Earthquakes - 12/03/2013 07:41

If you are watching the Global Incidents Map, you will see continuous tremors occurring (being registered) in Southern California. The region of the Anza in the Riverside country, NW of the Salton Sea and SE of Los Angeles at a depth of 7kms.
According to the USGS, the initial EQ was registered at M5.2 only to be downgraded to an M4.7.
Susan Hough, a seismologist at the USGS, has stated that the initial couple of quakes (the first a foreshock) had sent the monitoring system into a confused state and began recording multiple smaller tremors every minute or so.
As the day pans out, a clearer picture of the actual situation will happen.

Re: Earthquakes - 12/03/2013 09:56

It does seem there is somewhat of a clustering of M1+'s and M2+'s occurring around the regions west of the Salton Sea and around the Los Angeles areas.
The Global Incidents Map is still registering (from the USGS) regularly occurring rumbles. Let's hope for the communities there that this is not a sign of a bigger quake to come or reoccur.

Now, some of you may think I'm being a little morbid by posting the following live webcam link to a Los Angeles live seismograph, but it helps confirm the rumbles they are experiencing at the moment. At this point I believe there may have been over 200 tremors involving the area.

Something is not quite right with this clustering. Many residents are feeling quite unnerved. Hopefully it is similar to a cluster which occurred some months ago and settled down.

Hi Locke, just a quick one here, coz gotta dash.
Yes, you're right, re: the quake and if you are looking at the Gobal Incidents Map, you may not find all of the other worldwide quakes (generally) and the one in California, as the the Global Map only displays 100 events at a time (the latest ones).
There have been about 400+ tremors in California in the last 24 hours (abouts).
I'll post some other links when I get back later, so that you can see more of the worldwide tremors/quakes.

Re: Earthquakes - 15/03/2013 09:17

Yeh, Bello Boy. There are alot of rattled nerves in the California regions at the moment.
The fear is (according to what has been mentioned on some websites) that this is a sign of a rather large EQ potentially to come. Some are actually convinced of a potential disaster scenario for the west coast.

There are animal strandings, migrations and other unnerving animal/sea-life happenings in several parts of the US (this is also happening in other places around the world).
There are issues with gas/other bubbling up in waterways and other activity clustering in some regions.
The recent activity (clustering up and down the California regions) is being attributed (by scientists) to faults activity - horizontal slip, catch and grind.

Only time will tell what all of this rumbling means for the Californians. I feel that this movement may also involve the coastline bordering Canada.
As I have said on my blog, other movements may become more pronounced in the lower/middle central to the eastern states of the US.
Florida is having it's unfair share of issues with sinkholes, tremors, gas/other bubbling and waterway/sea edge issues. Many residents (100's) have had to relocate due to their problems there and the extent (spread) of their problems is still uncertain.

There is so much I could gabble on with regarding this subject, but I don't want to hog this 'space' wink

The general info I post here is just that, general - as I don't get a lot of time to focus on this science (EQ's) too much, unfortunately.
I sometimes miss adding extra interesting stuff and sometimes I may 'pull one out of the bag'. smile

Anyway, NSW had an offshore M2.4, NE of Ulladulla this morning. The apparent plotted position of this tremor is on a 'line' (sea floor crease) (for want of a better word) which points back to the shoreline near Ulladulla. It also (offshore) intersects with another 'crease' (at sea) which runs parallel with the coast.

There was movement evident on Melbourne seismo's and my own daggy one around and after that time.

Cheers for now.

Re: Earthquakes - 15/03/2013 21:42

An update on that bubbling river in NSW - here

Also the Indian Ocean 'triple junction' has has an M5 in the last hour - depth of 10kms. This is sort of halfway between the west coast of Oz and Madagascar - but a little closer to Madagascar than Oz.

The Queen Charlotte Islands (Canada) has reactivated with M4+'s again today. I felt that the 'movement' in California was not going to be isolated to that (US) area and it could shift north to involve Canada (in my amateur opinion).

There's been some interesting activity on the Melbourne Uni's seismo's today, at times when not much has shown up on, e.g., the Global Incidents EQ Map or Geoscience in relation to Oz - so the reason for the activity is unclear atm.

I was going through some old photos today and came across this shot, that I took about 5 years ago. I was standing on the sea wall of Lake Barely Sailable (aka Burley Griffin to non sailors) when an earth tremor mid morning caused ripples to radiate off the sea wall.



I didn't realize at the time that these ripples were caused be an earth tremor. I heard later in the day that there was an earth tremor at 11am, the time when I took the shot of what I thought were ripples that formed for no reason.

Yep, I'd say there must have been some 'tectonic' shifting and grinding going on there....the potential of a deep volcano attempting to form, but extra deep seated agitation of a different kind averted the changing of our 'landscape'. 'Energies' have been redirected - something brewing for September 14th (?) (election). It may involve just minor land/sea level disturbances, landslides or the formation of more deep fissures with the potential of swallowing individuals whole. Time will tell.....(ok, that was a bit silly poke )

Anyway, still jotting this on a friends computer - won't be up and running on mine till next week mad The t'phone co. has to disconnect part of my service (and someone elses) to rectify the issue (not our fault). Long story....and annoying.

The old techy in me managed to get my internet etc. working finally. Hope it lasts smile
Been monitoring some seismo's in Melboune this morning and have observed some faint jolts and subtle movement.
Not sure if this is related solely to Victoria or if it is reverberations from another location in Oz or to do with Santa Cruz Islands regions??
If you jump on the Melbourne Uni seismo you will see what I mean.
Nothing has shown up in Geoscience or the Global Map as yet.

The Canary Islands have been very active in the last few days - volcanic related?
Santa Cruz Islands and surrounds have been reasonably active. The PNG region may come up with another sizable quake...?

The west coast of the US (into Canada) may come up with another coastal/offshore M4(+?).

The Mediterranean region may also come up with another M4(+?) in March.

These and any other mentions of possible's (M's) are just feelings and not absolute predictions - as I always say.

The sinkhole issues in Louisiana are continuing, with one of the latest ones' swallowing an acre of farmland.....no one thankfully injured to my knowledge.

Re: Earthquakes - 26/03/2013 13:59

At the beginning of March, I mentioned (in blog) that I felt Portland (Vic.) may experience a tremor. Early yesterday evening Portland, on coastline, had an M2.9 (depth of 10 kms).
It must have been influencing some of the movement I noticed prior, during and after its movement. Tunisia is another I felt would experience a moderate EQ.
I gabbled on yesterday about Melbourne seismo's activity. In my last post I mentioned Melb. Uni's seismo going beserk. Since then this particular instrument has been taken off line - must have been a gremlin in the 'system'. Sometimes seismo's can need to be re-calibrated. But the movement prior to this (earlier in the day) was very interesting.

Re: Earthquakes - 27/03/2013 10:23

South east of Perth, SW of Kulin, had an M2.2 (5kms deep) early this morning.
The SW 'corner' of WA is probably (seemingly) the most active part of Australia at the moment.
The tremors, one offshore of WA (24th March) and Portlands' most recent tremor appear to be related/located to 'joins' (meeting) in the Australian plate. This has me feeling that the Indian Ocean central and central east plate points may come up with more movements in the near future.
The Portland movement may be followed by other movements west of Tassie and maybe north of the coastline (perhaps NW on or off the coast) of Tassie.
The point of due west of Tasmania/due south of the WA/SA border (at sea) may also show a movement.
(All just feelings - not predictions wink )

There have been almost undecernable vibrations in Victoria,perhaps due to distant EQ's and subtle movement in Vic. itself.
SA, I am suspecting, has had some subtle movement as well (for the same reasons as Vic.).
The other states of Oz have been seemingly 'quietish', with the exception of reverberations in Qld and NT/WA of EQ's in nearby countries.
Quakes (large ones) in other parts of the planet register on seismo's almost worldwide.
I often wonder with such larger EQ's, if the intensity of their movements jiggle other faults/creeping in other countries.

Below, some interesting articles;

A 'new' pool of magma has been discovered west of the Nicaraguan trench - article

A massive earth split has occurred in Brazil - article

Earth cracks in Arizona - article

Also the California coastline and inland are experiencing another EQ cluster. Maybe another M4(+?) to come.

I've been watching this list of seismograph readings which covers stations in South Australia, Victoria (Newstead - NW of melbourne) and one in NSW (Aranda, ACT).
Have a look at the bottom seismo (located near Willalooka in SA) and the vertical movement of the reading.
These seismo's update every 30 seconds or so and what you see on your screen are readings for the last hour.

California came up with the M4+ I felt it might. There may be more to come (unfortunately for the folks there).

The Ring of Fire has been quite active with M4+'s in the last 24 hours.
The Canary Islands (volcanic issue) may be an ongoing concern.

More, as I get time.

D.W. IS there a site you can direct me to regarding slip zones in N.S.W.,i ask because a friend has an acre,s in the Hawkesbury and part of a hillside slipped into his dam over the last week.
Posted by: duckweather

Re: Earthquakes - 01/04/2013 23:03

Hi GDL.
This landslip may or may not be attributed to any or none of the following;
**Water/runoff or natural water course activity undermining the hillside (can seep under-surface through cracks/splits and/or porous soils/ground base materials [e.g. sandstone etc.]
**Seismic activity destabilizing firm or fractured and/or unstable grounds [sometimes can be combined with increased water logging]
**Deforestation can contribute to destabilization of subsoil and surface grounds
**Commercial activity in the area
**Road construction above the slip zone
**Re-routing of waterways.........

The list could be endless....
Remember, I am not a professional in this science, so I can only offer limited ideas and thoughts here.

Your friend, himself, could survey the area [from where the slip occurred] and even get a professional [environmental, soil or other specialist] to help ascertain the reasons, effects/consequences [now and future] of the slip. I know I would want to learn if there were going to be any further movements and/or what could be done to prevent, combat or even predict further movements.

There seems to have been moderately consistent [and intermittent] faint seismic tremoring in Oz's lately. Combined with the reverberations of the larger quakes in the Pacific and in countries north of Oz, the Ozzie mainland is being jiggled a little (in my amateur opinion).

I'll pm you with some links which may be relevant to your friends location.

Sounds like the Dam has undercut the hillside. Or maybe over the years the runoff has done the trick. The gravity acting on the crest doesn't change but there is less material supporting the weight and it gave way.

Anyway, been watching the South Oz, Vic and Canberra seismos on another computer - and especially Vic and SA have been rattling (subtly) away today. Have observed the movement on my cave-man seismo here.

Canberra has also experienced movement of some kind - strange seismo action actually.

The Geoscience site has noted a WA movement of an M1+ in the last 24 hours, but nothing else. Currently their site (info on movements) appears to be down - I think it may have crashed due a high volume of people trying to connect with it.

Willalooka (SA) and a couple of other SA seismos have shown some interesting movement. Willalooka has shown almost continual vertical (like a gentle wave) of movement.

Currently compiling another post for April for my blog. Will post it when I get another chance to use my now best friends' computer smile

Cheers for now, Duck.

P.s. how's your friends dam (landslip) situation GDL? Hope he's getting some answers/ideas there and no more of a possibility of another slip.

Re: Earthquakes - 06/04/2013 16:05

Papua, Indonesia has just had an M7+ quake (80kms depth).
I was just saying to my daughter this morning that I felt (overnight/dream) that there was possibly going to be an M7 to M9 near Australia. My feelings were tending to the north of Oz today. Feel a little numbed.
I hope that the communities in Papua are ok. There will be more info coming soon on this large quakes effect and potential damage.
The western edges of the ROF, I strongly felt were going to experience M5's following North Korea/Russia/China border region M6+ (very deep). This has occurred from Japan down through to above NZ.

Re: Earthquakes - 06/04/2013 16:53

Just to add to my post above, this large quake appears to be situated in a mountain range, above a valley which stretches west to east/east to west. The quake is not associated with current activity on the island (according to maps displaying currently active volcanoes). There is no tsunami warning (as it was on land), but the seas surrounding the island may have shown signs of disturbance.
I am guessing there may have been villages near the quake which could have been affected somewhat.

This quake may have been felt along the top of Australia.
The reverberations sent our seimographs off the scale.

Hi folks.
As many of you are aware, it has been a challenging week for my family. But I thought, in a quiet moment I'd jot some short notes on the earthquake thread.

The region including the eastern side (and down the southern regions) of South Australia - through to the western edge of Victoria have been showing (as displayed on several seismographs in Vic and SA) some interesting movements. The Willalooka seismo is still displaying what looks like a gentle wave 'movement'. I'd like to know what the folks are experiencing there. Some readings have been a 'reaction' to quakes overseas, but I am sure there is an 'isolated' (in the general region mentioned above) energy/pressure rumbling away here.

My usual focus on this thread and earthquakes in general is a bit scattered this week, but hopefully by next week I'll have a clearer perspective for the info for this thread. I have added a little to my blog as well.
To add to all that has happened for us this week, I had to jump out of my car to save a 2 year old (wandering the streets alone) from getting run over. Every parent's nightmare, especially to have a child go missing.

Anyway WZ's, thanks for your understanding and kind messages this week. Very much appreciated, Duck.

Re: Earthquakes - 12/04/2013 17:11

Today there was an M4.6 in Franz Josef Land.
Now, I don't normally make light of any earthquake, but this quake is in the region near the North Pole, an archipelago far north of Russia (Russian islands). The quake is possibly near Rudolf Island (bit hard to tell on the maps at the moment).

I find this quake (apart from what I've said above) to be quite curious. Currently I am unable to see what plates maybe involved or volcanoes. Personally, I haven't seen one pop up here, but someone else may be able to fill the details in on this one.

I said some time ago (on my blog) that we may see EQ's/tremors start to pop up in unexpected places. I still feel we may see some more 'movements' in other places too this year.

I also get a feeling that the south of Oz (SA/Vic) may come up with an M3+(+?) soon. When? not sure - maybe within the next month or so. (As I say on my blog - what I say are just feelings not predictions).

Cheers for now.

Re: Earthquakes - 12/04/2013 21:49

Just an amateur observation here (and I could be completely wrong), but these seismo readings have calmed considerably after Indonesia's EQ of M5.4 (103kms deep) 45 minutes ago.
Prior to this quake, these seismo's were displaying some jitters, about 5,10 to 20 (or so) minutes apart. My query - 'could the prior (to quake) movements on our seismo's have been an indicator (some of the jitters) to movements building up to the quake?' Just a thought........

Posted by: duckweather

Re: Earthquakes - 13/04/2013 13:45

Hi zuldjan.

This is the inkling I'm currently getting (and I could wrong here)....the pressure of various sorts may be building along the western edge of the ROF. This includes northern Japan, down to Indonesia and through the Pacific Islands (Fiji etc., and especially the Santa Cruz Islands), then sweeping down towards New Zealand. Just a feeling.

Alternatively, there may be a 'pull' along the west coast of the U.S., and/or Central America and/or South America...???
The region of the Gulf of Alaska may also be included in this (??? and the Queen Charlotte Islands too ???).

If you've noticed, the instability in the west of the ROF seems to have coincided with a mild quietening of the east of the ROF. (No science here, on my part, just inklings).

Posted by: duckweather

Re: Earthquakes - 14/04/2013 12:46

As I suspected, zuldjan, the movement (pressure) I mentioned in my last post has occurred (when I felt it would).

The large movements in Japan and Indonesia recently were a precursor (in my opinion) to this movement. The building jitters for these M5++ quakes were registering in Oz's seismo's.

This movement may continue to the east, towards the Solomons, Wallis and Fortuna, Tonga, Vanuatu etc.. They may see more M4+'s(+?) - could be wrong.

Re: Earthquakes - 15/04/2013 00:20

I knew I wasn't imagining things.
A tremor registered with me tonight (actually Sunday evening, about 11pm).
Rye in Victoria has just had an M2.7 (6kms deep).
Call me Daffy Duck if you like grin , but I could hear a faint 'thunder down under' (I like to call it) around this time.
This may be on a fault line which runs from Bass Strait and up on a NE angle. Though there are other faults which intersect this approx. region.
Will look at the fault lines in the morning to check which one it may be, as I get a hunch this may be the first of one or two more trembles/tremors - maybe.
Posted by: duckweather

Re: Earthquakes - 15/04/2013 10:17

As I mentioned in my previous post early this morning, the tremors I suspected were going to continue for Rye, Victoria, have occurred.
2 tremors have occurred - minutes apart about 108 minutes ago.
For 3 tremors to have happened with a space of 11 or so hours is very interesting. Precursor to another or more of similar magnitude (M2.3 and M2.5) maybe, or maybe one of an M3+ nature, not sure time will tell. But there is definitely some instability of sorts happening there at the moment.
Haven't had a chance to check the fault maps yet.

Re: Earthquakes - 16/04/2013 21:05

I get a feeling that a larger EQ may occur any time from now. Meaning in the western (lower) Pacific region - maybe in the region of M5+(+?) - though I could be wrong.

As I was typing this the seismo's (SA and Vic) have gone off the charts - so to speak. I'll check why and get back.

Quick check - Iran/Pakistan border has just had an M7.6 100kms deep)! Not the Pacific like I felt it may have been.
France has had an M4 and Oklahoma has had at least 4 quakes today (largest M4+).

Hi Trav Dog.
Yes, at the moment Geoscience has it at 0kms deep (nasty), the USGS has it at 15.2kms and the CSEM-EMSC has it at 100kms.

It was felt over a very wide range, through the Middle East, India etc..
A quake of this size could leave an expansive 'trail' of damage.

Near the north coast of PNG has had an M6.8 (10kms deep - shallow). Global Incidents Map

Yesterday, I mentioned in a post here that I had a strong feeling that an M5+(+?) [in my terms means a potential M7 or M8] was going to occur in the lower west of the Pacific from the time of such post.
The large quake in the Iran region occurred as I was typing that post, and thought my 'radar' must have been off. But, the feeling of a large quake didn't subside. I still had a strong feeling that another near PNG was going to occur, unfortunately.
Let's hope that this latest quake has not adversely impacted the PNG communities.
These large EQ's must be indicating some serious 'shifts' in the plates. At this stage, it seems this may be the case, unless another reason (e.g. volcano related?) arises soon.

Thoughts on a big quake possibility in Fiji region?
Posted by: duckweather

Re: Earthquakes - 17/04/2013 16:54

Hi zuldjan.
If you are asking me, I get a general feeling that Fiji may be at some distance from a major quake (meaning M7+). Fiji is SE of say the Santa Cruz Islands, which are positioned on plate 'deviations' (leading back through to PNG and Indonesia, and back up the western edge of the ROF). These regions may be more prone to the larger quakes like the one we saw today in PNG.
Generally speaking, Fiji may see some movement in the meantime, possibly in relation to the ROF misbehaving at the moment.
With my limited knowledge, Fiji may experience M4+(+)'s (meaning M4 or M5 or an outside chance of an M6) here and there when the plates become agitated/move. I get a feeling that Fiji's EQ's may be generally offshore/at sea.

But hey, this little Duck can never be sure where the next biggy is going to occur. One can possibly guess and intuit where movements may occur by following and studying daily EQ, volcanic and other things to get a general picture of possibilities. Even I don't get much of a chance to do this unfortunately. When I can focus on earth movements, I can sometimes get hunches for 'patterns' or signs, possible energy distribution and/or displacement etc.. But I just go mostly on intuition (gut feelings and other signs).

Anyone who reads my posts and gabbling's-on must remember that I am not always right. They are just feelings, not predictions.

Cheers for now, Duck.

Oklahoma has/is experienced a cluster of tremors. This info mentions that there have been at least 32 tremors in the last 24 hours or so and the scientists (geological) said that "the frequency and number of the quakes was unprecedented in Oklahoma".

Some of the Japanese lands/regions are also experiencing M5's fairly consistently at the moment.

Re: Earthquakes - 19/04/2013 13:54

The Kuril Islands M7+ EQ('s) was 10kms deep and located, according to the coordinates directly under/around the Chirpoi volcano, which has been showing signs of activity.
Though there is no tsunami warning, the buoys in the regions are showing considerable up/down movements (height/depth variations) of about 20 metres initially. There is bound to be water level/behaviour reactions to this large quake, especially considering these quakes are quite shallow.
Subtle vibrations could be felt through the ground here in Oz, and are still faintly occurring.

Re: Earthquakes - 19/04/2013 14:00

Just received this email from my brother who lives and works in Yuzhno in Sakhalin 600 odd km's west of that quake.

"Ooh we just had a pretty big earth tremor... sitting here wobbling for about 10 seconds or so.. the fan standing on the floor was wobbling from side to side.....

... a little wee came out !"

Re: Earthquakes - 19/04/2013 14:16

That's very interesting Ruckle. I would have been quite unnerved too.

If you want to 'see' the vibrations currently running through the 'ground', place a full cup of water on a table (away from any other movements - quiet spot) and watch the water surface vibrating.

I can actually hear the odd rumble, coinciding with the vibrations (I know...you probably think Daffy Duck is a little strange). seismo's Vic, SA and Canberra regions

Tectonic Summary
The April 19, 2013 M 7.2 earthquake ENE of Kuril’sk, Russia, occurred as a result of oblique normal faulting at intermediate depths within the subducting lithosphere of the Pacific plate. At the latitude of this earthquake, the Pacific plate converges with the North America plate (and the smaller Okhotsk microplate) towards the west-northwest at a velocity of approximately 82 mm/yr, and subducts beneath the Kuril Islands at the Kuril-Kamchatka trench, some 160 km to the southeast of the April 19 event. The depth of this earthquake, and its oblique-faulting mechanism, indicate that it involved intraplate faulting within the subducting slab, rather than being an interplate thrust event on the shallower seismogenic zone between the two tectonic plates

Re: Earthquakes - 20/04/2013 11:17

The M7 (+?) EQ in Sichuan, China, which is very near a populated region of Chengdu, approx. 16.4kms deep (according to the USGS) has rattled seismo's almost worldwide. But most importantly, let's hope that the communities (peoples) haven't been poorly impacted by this large quake.

Another EQ, just north of Western Australia, south of Timor, of an M5.8 magnitude and estimated to between 9kms (USGS) and 29kms (Geoscience) deep. This most certainly could have been felt along the top parts of OZ. No buoys seem to have been set of (event mode).

There have been a number of these larger quakes occurring in seemingly quick succession. I had a feeling, unfortunately, that this may happen in this period of weeks (mid April).
Generally speaking, the 'movements' are happening in the west of the ROF. But I am suspecting that the eastern side of the ROF may come up with potential corresponding movement - time will tell.

Re: Earthquakes - 20/04/2013 18:48

The Bouvet Island region (south of South Africa) came up with an M5.3 3 hours ago. I have a faint feeling that this being to the west of the Indian Ocean,possibly may translate to a movement to the east (west of Australia), maybe SE of Madagascar???.....

Re: Earthquakes - 21/04/2013 12:07

Was just about to say that something was brewing near Australia, after spending some lazy time watching the regular and consistent movements on these seismo's when Papua Indonesia came up with an M4+. But the seismo's are still quietly rumbling away - soooo I am still feeling there is some unexpended energy to be released somewhere at the moment.
This could be north of OZ.
We'll see......

Now for a while we will faintly feel vibrations (get your cup of water handy) from this movement.
Again, let's hope no communities were adversely impacted with these quakes.

Re: Earthquakes - 21/04/2013 14:45

Feeling a little like I am hogging this 'space' at the moment, but the seismo's (mentioned in previous posts) are still quietly rumbling along. This leads me to feel that just maybe that the movements above Oz are not over yet.
It's been some time (over an hour or so) now and I would have imagined the seismo's may have 'settled' a little by now (in my amateur opinion).
Maybe....the energy will travel south from Japan/China/Taiwan....???
Posted by: duckweather

Re: Earthquakes - 22/04/2013 11:34

I've been observing some movements (perhaps of a low magnitude, such as M 0.5 or less) on the Melbourne seismo (which is corresponding to the movement I am seeing on my daggy seismo here in Melbourne's outer east).
This may indicate some local settling/jiggling in the fault which recently gave us an M3. But don't quote me on that, I could be wrong.
I am guessing this, because when you look at these seismo's collectively, when the movements are universal (i.e. each seismo showing similar movements at the same time), you could presume that these movements are a repercussion of one larger EQ at a distance or nearby.
But Vic's current jitters appear to be isolated to this region at the moment. This may mean a precursor to another movement or jitters from the recent tremor - we will see.

As I felt yesterday, some movement in the regions above Australia, followed on from the movements further north in China/Japan/Taiwan. (Again - a laymans observation).

Cheers for now.

Re: Earthquakes - 23/04/2013 08:04

Just a quick note - just under an hour ago, our seismo's registered a generalized movement of what may have been a distant large quake or a local (SA?) maybe M3 or M3+, not sure - but nothing is showing up on the Global EQ Map or Geoscience.

Re: Earthquakes - 23/04/2013 09:48

I am surprised that the Iran 7.8M earthquake has completely dropped off the news cycle. The reported casualties were only from Pakistan - with reports that hundreds of homes were totally demolished:

Quote:
Roughly 1,000 of the 1,200 homes in Mashkel were demolished in the quake, said Col. Saqiv Elahi of the [Pakistani] paramilitary Frontier Corps, which has a base in the town and has been providing some aid to residents. Elahi said many of the houses that did not collapse have dangerous cracks in the walls and roofs that make them uninhabitable.


But maybe that's for the best - and there really was no major loss of life...
Posted by: duckweather

Re: Earthquakes - 23/04/2013 10:37

I agree Arnost. News turns over so quickly these days and when the eyes of the world are on other nasty situations like the Boston bombings and the fertilizer plant explosions in Texas for example, some other impactful happenings like China's and Iran's quake ramifications become less exposed in the media.
But, their stories are still out there and being followed on alternative web news sites.
Sadly it seems that nearly every day there is some new 'event' of an unpleasant nature being reported on or in press releases.
Sometimes 'you' wonder what the world is coming to.

On another note, the movement I observed on the seismo's earlier this morning looks like it may have been a response from the M4+ quake in the Kermadec Island near New Zealand. It was quite deep. As I am typing this post, the Kermadecs have just had a larger quake of M5.5 (quite shallow, being reported as being between 0kms and 10kms deep).
It appears that the deeper the quakes (overseas) the more impact their movement have on our seismo's. The shallower ones appear to have a lesser impact on the seismo's here (generally speaking).

Cheers for now, Duck.

Re: Earthquakes - 24/04/2013 07:21

Good morning folks.
About 30 minutes ago, a Melbourne seismo registered a movement in a lower range of maybe an M2(+?). Will see if Geoscience records this as a tremor for us.

Posted by: duckweather

Re: Earthquakes - 24/04/2013 16:30

Apart from PNG's M6+ EQ today setting off the seismo's considerably, Victoria (NW of Melb's seismo) was definitely rattling in small doses intermittently (sometimes 5-10 minutes apart). This activity has been steadily increasing in number.

South Australia (SW of Hawker?) had an M2ish early this morning, but with all the intermittent activity on the seismo near there and in Vic, I feel there were more small tremors which didn't show up on Geoscience site (obviously they'll have more info on this than little old me). Arkaroola in SA also had an interesting 'spike' today.

My observations above are a bit thin on info, as I have been quite busy today, but will keep an eye on our activity tonight.

The Mediterranean Sea region and the SW coast of the US is drawing me to them a little for some moderate movement (maybe M4 or M4+?)...
Posted by: duckweather

Re: Earthquakes - 27/04/2013 10:12

Hi folks.
I haven't been very focused on EQ's lately, as I have been very busy with other things in the last 5 weeks. Some of my feelings recently have been spot on and others a bit skew-wiff.
But anyway, got a short moment to have a 'look' at some general feelings about potential energies, so let's see if my radar is off or re-aligning wink

I get a wee feeling that there may be a southward pressure from the bottom of the Kamchatka region, through Japan, directly down the west of ROF. Maybe translating through to the regions around Vanuatu, Fiji, etc..
The Banda Sea region (including to the west and east of) is niggling at me a little.

The eastern states of the US have been sporadically coming up with M2's and M2+'s as I felt it would (mentioned in blog).
The western US regions has been jittery, but I still feel that from Canada down to Baja California, there may be an M4(+?) pop up along the coast at some point.
The west of (off shore) of Grants Pass, Oregon (lower SW of Oregon) and west of Eureka, California (off shore) are still sticking with me. San Diego (off shore) is another which, for some reason, is drawing me to it as well.

I am still drawn to the Mediterranean region, Crete and west of, for some reasonable movement.

Anyway, I won't gabble on any more, as my usual 'lists' of thoughts I note on my blog is extensive and to put it all here would be totally hogging 'this space'.

Melbourne's SE has had some amazing cloud (ribbed) formations this morning....??? and a NW Melb. seismo is still jittering with small spikes intermittently.
The seismo near Hamley Bridge in SA is showing some continual/regular movement, along with some smaller movements in the other seimso's , which could be an indicator of a pressure building in the west of ROF/north of OZ..?????

Let's see if my radar is off here and there still - you may yet say to yourself, "Tell here she's dreamin'" smile

I haven't seen this sort of generalized movement for a while. It will either culminate in a sizable tremor or could be a gradual release of energies (shifting in plates)...will see.
I can't get up the seismo's for the rest of Oz, but I am presuming they may be also reading similar movements as well.

Re: Earthquakes - 28/04/2013 11:23

Just as I suspected, Melbourne's NW - seismo S88Bv and Melb NE seismo (Leon Mow) have registered movements in Vic.
In one of yesterday's posts I mentioned the cloud formation in Melb. SE.. Some may not believe in the relationship between cloud formations and earth tremors, but even on the sat pic yesterday I noticed the ribbed cloud formation was stationary at one point, whilst the rest of the cloud barreled in from the SW.
This particular 'cloud' was in Vic's SW and SE.

Hi folks.
It's been 'quiet' by degrees worldwide on the EQ front.
The Mediterranean regions, spots in the Middle East, the California coastline, spots in Middle and South America and the Alaskan regions have been the main areas for either clustering of tremors (e.g. California and Alaska). Japan has been experiencing daily tremors - about an average of 7 per day.

For Australia, the total number of tremors registered with Geoscience, from the beginning of April to the time I am typing this post, is about 29 confirmed rattles;
WA = 15 tremors
Vic = 3 t's
SA = 3 t's
NSW = 7 t's
TAS = 1 tremor.

But, though I have noted the Aussie tremors, there have been reverberations from these and overseas quakes which have jiggled our seismo's in Oz. Also, though there have been recorded tremors in Oz, there have been regular periods of vibrations occurring. Just have a look (for example) at this seismo HERE , which is recording series' of vibrations of approx. 20 minutes in duration each - separated by approx. 20 minutes of settling somewhat.
Some seismograph registers have been a build up to tremors, post tremor movements; movements from distant and near plate jitters and other deep disturbances and shifts of energies. Therefore the 'vibrations'/movements are not just isolated to the time/date formally recorded as an EQ with the various agencies (e.g. Geoscience, USGS etc..).

Anyway, for now,
Cheers, Duck.

Re: Earthquakes - 30/04/2013 13:52

Just a quick note -
I am getting a feeling that Vic and/or SA are brewing for a small tremor.
Mount Rat (SA) has just had a small movement, came up as I am typing this.
If the movement I am suspecting may occur is not local to these regions, it may be that something is building (I don't mean big) offshore (could be north of Oz, south or east of Oz, or NE)
If I am wrong, I may bury my head in the kitty litter with my error of judgement here smile (sorry, a silly moment)
Posted by: duckweather

Re: Earthquakes - 01/05/2013 11:02

Ok...no need to dunk my head in the kitty litter atm. The Melbourne seimo NW has registered some small spikes, my guess they may be in the range of M1.
If you have a look at Willalooka's seimo on the above link, you'll see it is showing that mild vertical long wave movement at the moment - curious.
The western edge of the ROF is still generally very 'quiet' at the moment, but I don't think that will last for much longer - unfortunately.
The buoy, over the last 36 hours or so, under (SE) Jakarta has been showing some rather large height differences/movement. A couple of days ago I mentioned my suspicions about potential plate agitation for this region.

Cheers for now, Duck.

Just another wee note, particularly for the folks in Victoria (Melbourne to the SW and towards South Australia border?) this seismo is showing almost continual movement since the M3 in Geelong this morning.
SA, near Olympic Dam, has experienced an M3.4 today too.
(My son told me to post this, as he has been watching the seimo a little today [a bit of a distraction from other things today] and is fascinated with it. Bless him).

Re: Earthquakes - 04/05/2013 11:04

Hi folks.
Just another short post for the time being.
The Banda Sea came up with a reasonable movement (M5+) as I suspected it would, as did Victoria and South Australia. And, some activity above Oz towards Indonesia.
Below Western Australia (offshore) has had an M3+, and if you include in the picture the other tremors that have occurred in the lower regions of Oz, my feelings that the plates below Oz are possibly somewhat agitated may be correct. A guy in Japan seems to think that this energy may be emanating from energies from the Indian Ocean plates too (if I can find the link to his page again, I'll post it here - but it is in Japanese).
Yellowstone NP seems to be experiencing some moderately regular tremors (mostly small) this website gives an up to date list of tremors being recorded in the Intermountain West region of the US. And if you are interested, here is the live webcam of the Yellowstone Geyser Live
There seems to be some possible plate agitation (not sure if it is undersea volcanic) SE of Tasmania, close to the South Island of New Zealand. A buoy has registered a short time water column height difference of about over 100 metres.

For the moment, Duck.

Re: Earthquakes - 08/05/2013 17:19

As I anticipated in earlier posts, South Australia and Victoria have been experiencing tremors quite regularly (seemingly) lately. It seems that our respective faults in these regions are experiencing some jitters and I feel (hope I am wrong) that we haven't seen the end of them yet.
The earth, of course, is not a static entity and there are 'always' extremely subtle vibrations occurring every day, ranging up to the tremors being recorded officially by Geoscience Australia .
The ribbed cloud formations today have been very extensive across Melbourne (this of course doesn't prove a correlation between EQ's and atmospheric conditions).
The Japanese poster (whose site I am yet to find again) was right when he said that the Indian Ocean plates were going to be on the move again (Mid-Indian Ocean came up with an M5). He and I seem to be on the same 'page'.
I hope to get a better chance to jot more of my better posts here in the next few days.

I meant to add this video too, about an earthquake which occurred on the San Andreas fault line. This vid was uploaded in April of 2007. The movement begins at about the 47 second mark of the video and after this there is no other movement seen for the rest of the vid.
Apparently ground cracking opened up here in the days following the quake.

Southern Iran is really copping a series of aftershocks from their main M6+ today.
Here's a news article from SBS World News
Leading up to the main quake, I was feeling that such a quake may possibly have occurred today/this weekend slightly more to the east, towards Pakistan.
The Mediterranean sea coast (Libya) has come up with an M4.7, which is not far from Tunisia ('next door'), where I felt one may occur.
Let's hope, as usual, that the communities aren't poorly affected.

Good morning folks and especially best wishes to all the mums out there for Mother's Day x.

Tonga's M6+ this morning was quite deep at about 205kms (USGS).
Here is the USGS map and info on this quake. No tsunami warning has been issued.
If you notice the red lines, which indicate the edges of the plates, I have noted in my blog notes for May (which I haven't had a chance to upload into my blog as yet) that I felt this region (plate boundaries) was being squeezed by the general behaviour of the ROF. (Remember, these are just feelings). And that this 'pressure' may help produce some sizable earthquakes at a moderate to deep level in the plate boundaries in this region.

Other regions I felt (May blog notes) which may experience a larger EQ is Afghanistan, SW or E Turkey, Tanzania, southern Greece, Lower Central America, east of Madagascar, Antarctica (either due south of the South Sandwich Islands or due south of NZ), (mild feeling for) between L.A. and San Diego (offshore?) and for some reason Texas is sticking with me - just a few regions from my notes/thoughts.
(these are not predictions, just feelings)

Anyway, I'm off to enjoy some mummy-will-be-fussed-over time with my 3 beautiful ducklings (kids).
For now, Mumma Duck.

Hi TCTP. Thankyou for your compliments on my blog and info blush
My thoughts/feelings/notes are general and amateur in nature. I just have always had a fascination with all things 'earthy' since I was a little tacker.
Lately, I have been very distracted with other things and have not focused on my blog, but I hope to upload my notes for May soon.
You're more than welcome to link/refer to my blog. I had hoped in creating it that like-minded or curious others may find it interesting. Remember the contents are not predictions, just gut feelings. Sometimes I am very wrong and sometimes I am correct. Not everyone, I would imagine, is interested in this and some may even feel that what I natter on about is hocus-pocus, but that's ok.

Just briefly, I feel that the M6+ near Tonga today may still be quietly 'moving'. Just a gut feeling looking at many of Oz's seismo's. I also get a bit of a feeling that the Indian Ocean (and below Oz) may come up with another jiggle....???

'Sunny days' in her solar thread (in the lounge forum).. has mentioned a drop in solar wind inherpost tonight and is expecting an increase in earthquakes .

Here is a research study correlating solar activity with earthquakes on earth.
They have some graphs to show
-Earthquakes are more prevalent during Solar modern warming period 21st C
and again some correlation graphs to show
- less activity during long solar downturns like the Dalton and Maunder minimum.

They explain how the magnetosphere compresses and expands with solar wind intensity


They indicate they believe earthquakes occur in different zones depending on whether the solar wind is strengthening or weakening.

some quotes

"There was a clear decrease in earthquakes for the two grand solar minima examined and an increase in the number of earthquakes for the last half of the 20th
century. This increase in solar events, called the Modern Maxima, coincided with the intensification of earth-quake events in several plates.

..
Solar wind speed which causes more dynamic pres-sure on Earth’s magnetosphere is the physical mechanism which increases the number of earthquakes. Variations in solar wind during a Coronal Mass Ejection event can exert pressure, deforming and shrinking the magnetosphere by 4Re (Earth radius). The tension on magnetic field lines is analogous to the tension on a violin string.The pressure will affect the Earth surface in different ways depending of the tectonic of each region; some areas are more susceptible to release energy in a form of earthquake or other analogous phenomena (such as vol-canoes

Re: Earthquakes - 12/05/2013 22:21

That's very interesting Crikey. I often felt that earthquakes perhaps didn't occur in isolation (i.e. without the influence of other 'forces'). So EQ's possibly occurring in unison with or affected by another force of nature makes sense.
It's a fascinating topic, and like most 'things' in nature, usually the presentation of one condition has an effect on another part of nature - i.e. cause and effect - an interplay, a ramification, an irreversible or temporary effect, an alteration of states in some cases.
It's not just the chemistry of entities/objects etc., it can be the occurring and subsequent physics of it all too.

Re: Earthquakes - 14/05/2013 12:03

Mariana Islands M7 earthquake

This quake was very deep and apparently did not activate a tsunami. The quake occurred along the Mariana Trench.

These trenches, and the like, are the sort of regions/physical points which I felt may show solid activity, here and there, within the edges of the Ring of Fire. Just as I had eluded to the example regarding the 'ear-shape' junction in the plates near the Wallis and Fortuna/Fiji/etc. regions.

The well defined edges of the ROF will regularly experience the odd large quakes, because of the nature of it's being. But, the trenches, ridges and other deviations in the main plate (overall) will feel 'pressures' too occasionally and 'give' at the odd time.

As I mentioned in a previous post, EQ's as deep as the Mariana's can register some interesting, solid movement on our seismographs (as well as those across the globe). This movement is deep in the crust and though it didn't cause much surface damage or any at all (apparently), is still an interesting firm shift/movement regarding the plate/ROF.

For the moment, Duck.

Hi folks.
I've been a bit distracted with other things this week, so have not posted here in my usual gabbling fashion smile
These last few weeks have had me distracted regarding family happenings, as many of you know and just when we thought all was settling, I happened to be in the wrong place at the wrong time and experienced a potential car-jacking this week. But all's well. It shook me up a bit, but all's good now. My in-car camera excelled itself. They are invaluable things and I recommend getting one if you don't already have one.

Anyway, just briefly for the moment, I noticed Hawker in SA had a good small rattle on one of its' seimo's this morning - maybe an M2(+?), not sure 'til Geoscience confirms it.

In one of my last posts I mentioned the South Sandwich Islands (south of, near Antarctica) as possibly coming up with some moderate EQ's. Approximately 4 M5+'s came up actually east of the South Sandwich region instead. I kept getting drawn to this region, but my direction was wrong. This some considerable (multiple) movement in the plates there.

Just looking over my blog posts, many of the regions I felt may come up with EQ's (particularly what I mentioned in the March/April posts) have been occurring. I still haven't completed posting much for May, but June's post soon should be better with notes.

You can't help but think of the 'what-if's' after that. But there's no point dwelling - gotta get on with life.
A colleague of mine in Dubai asked me (and family) to go and holiday at her abode for a while, but as much as I'd love to take up her offer and see that fascinating place, I'd need a lotto win to get there and I'd may need to swim there, as I don't like planes (pathetic aren't I?).

On the EQ/tremor front, I am 'watching' the west coast of California and inland slightly atm., they are experiencing somewhat of a cluster of small tremors. Particularly from LA down to Baja, Californa. The Nevada region is a curious one too. Offshore Eureka is still twigging at me atm.

A couple/few posts back, I mentioned that I had a niggling feeling about Texas in the US. I quietly felt that there was going to be something on the biggish side there, apart from a potential tremor, another explosive type situation (explosive meaning something coming from above and/or ground level).
Most unfortunately, Texas has experienced multiple tornadoes and sadly six people have lost their lives.
Here is a CBC News report on this latest tragedy;
12 Texas tornadoes.....

I don't like it when I get those unnerving feelings about a region and my feelings just seem to 'hone-in' on an area.

Re: Earthquakes - 19/05/2013 16:48

Now...this info is more attuned to all that SunnyDays discusses in the Solar thread, but I'll take a chance and relate this for the first time to the earthquake thread this post.
Have a look at this article and especially the pictures/graphs/representations of the Geomagnetic storm.
Notice the 'red zone' in the Antarctic/below Australia and New Zealand, and the northern hemisphere (pole).
I am thinking that this just may affect earthquake activity in our region and in the northern hemisphere....just a guess at the moment...we'll see what happens.
The regions near the Middle East and towards Sumatra may also become affected by tremors.
Offshore California, near Eureka, has been experiencing tremors as I suspected it may.
Iceland may become affected by moderate quakes too.
Another may be the western end of the Aleutian Islands (Alaska).....more soon.
Posted by: duckweather

Re: Earthquakes - 20/05/2013 09:48

As I suspected they would, Iceland, New Zealand, Middle East (southern Iran), Sumatra and the western end of the Aleutian Islands (actually registering as the east of the Kamchatka (Russia) and the Kurils all came up with EQ's since my last post.
Willalooka in the far south east of South Australia is showing some rumbling currently. Hawker, north of Adelaide, has been showing the odd rumbling as well (probably in the M1(+?) range. Yet to be confirmed with Geoscience (no records of tremors on their site since the 15th of May).
Algeria, which I had in my notes for May, has also come up with an M5.
Victoria (on the S88B seismo, NW of Melbourne, and a seismo NE of Melbourne) have been displaying the odd spikes too.
For the moment, Duck.

Here's the list so far for South Australia I'm sure there is more to come.

Re: Earthquakes - 21/05/2013 13:01

Also...leading on from Arnost's post...there have been no aftershocks with this quake...interesting. This quake must have had some effect on the sea behaviour, maybe not a tsunami, but for it to have no effect at all would be a little strange. Apparently the quake was out of a land population range of approx. 100kms. Though, the nearby sea-life must have got a bit of shock/disturbance.

Kamchatka region is still unstable and, generally speaking, this region's multiple quakes remind me of the Santa Cruz Islands EQ behaviours recently - ongoing movement. There is a volcano nearby, Tolbachik. See "Bone Idle"'s comment below the article here - Kamchatka EQ's

For the moment, Duck.

It is either a Vic tremor to occur, or a prelude to a distant quake.
Posted by: duckweather

Re: Earthquakes - 22/05/2013 17:40

As I type this post, the overall 'picture' of EQ activity is eerily on the quiet side.
California, parts of the Middle East and Alaska are currently (generally) the only regions experiencing periodic tremor activity.
Melbourne's seismo (as mentioned in my last post) has settled somewhat. After checking other seismo's in SA and NSW, it seems the activity I mentioned was isolated to Vic. This may have been a subtle fault activity with perhaps no follow on tremors or maybe a precursor to some more 'shifting'. A totally way-out idea is that this movement may have some relation to Bass Strait - a professional geologist may be able to correct me or confirm this smile
Anyway, I am feeling drawn to the Mediterranean, Spain, SE United States, Madagascar, Central Indian Ocean, Banda Sea, North Arabian Sea, North Atlantic (maybe central) for movements.....but I could be very wrong.
Kamchatka and the central west coast of South America (and maybe even Mexico region, Central America) may continue to rumble....

Re: Earthquakes - 24/05/2013 10:07

Ok, back again.
Here's a short news report from NZ regarding Quake in Tologa Bay Tonga today.

This was a deep sea quake which rattled buildings, but did not create a Pacific wide tsunami. More reports will come out as to the effects of these quakes soon.
This is the region (and wider surrounds) which I have eluded to several times, as being unstable and capable of large quakes currently. The deviations in the plates in these regions seem to be rather prone to substantial movements by not only the nature and design of their shape, but also perhaps because of the apparent 'hot-spot' deep seated below the surface (plate depths/crustal regions).
There may be a possibility of some of the nearby islands, e.g. Vanuatu, offshore Fiji, PNG, north of OZ (offshore), the Solomon region, maybe down to NZ, maybe over (east) towards Easter Island and near the coast of South America (centre - down), Japan, Hawaii (smaller tremors) and central South Pacific Ocean (ridge - due west of the southern end of South America) experiencing some movements too. I could be wrong though.

If the Global Incident Map overloads and is off line at any point, you can also check out emsc-csem for current movements worldwide.

There are still ever so subtle vibrations emanating from this region, so it seems to be still settling and may produce another after shock or more.

The Mid-Indian ridge came up with an M4.7 today too, which I had said it would in one of my last posts. Info here

France came up with an M4.1, though near Spain - but it wasn't Spain as I had felt may experience a moderate tremor. I still feel that there may be one closer to Spain/Portugal.

(Remember - my notes here are not predictions, just feelings of where energies may be)

More soon, Duck

I had said that I suspected that offshore or just inland Eureka may experience a moderate quake. But, just inland near east of Eureka, near Redding, California has just had an M5.9 (0kms depth). This will impact surface structures, communities etc. by varying degrees.
Northern California

I had a niggling feeling that this region was going to experience a moderate tremor. West of this region is a jaggered plate junction (off shore). This plate junction is west of Eureka.

Brother just emailed me a reasonable shake where he is at Sakhalin in Russia. Unlike last time when he sent me an email and I posted it in here this one is not repeatable. He says it lasted longer than the one from the Kurils he reported previously.

This was a doozy Ruckle.
I just got home to see the seismo's and EQ maps.
I'm not surprised your brother's email content is unrepeatable.
Will have a look to see if this has volcanic activity relationship and any other info.
The ROF regions and the plates under Oz, New Zealand and in the Indian Ocean have been very active today. It left me with a rather uneasy feeling. There has been some serious movement.

Re: Earthquakes - 24/05/2013 16:37

3 volcanoes have a current eruption status (lava dome growth noticed earlier this week) and are spewing lava. These volcanoes are on the eastern flank of the Kamchatka Peninsula, and the M8.2 quake was on the western side of the Peninsula.
This was a very deep quake (crustal/plate movement) with the shift felt almost worldwide.
We, here, still have subtle vibrations being recorded on seismo's.
As I type this, the Southern Mid-Atlantic Ridge has just come up with an M6.5 and Southern California an M4.7.
This alot of larger movement for one day....

Re: Earthquakes - 24/05/2013 17:10

Just another note...Southern California's M4.7 is on the plate boundary - see maps/location here

Japan Meteorological Agency and other agencies have not, at this stage, issued a tsunami warning for Kamchatka, Russia.
Water disturbances can be expected though to some degree.

The southern mid-Atlantic ridge EQ (info) I mentioned earlier, has been removed from one site, bit it is still listed here.
Note: this quake has been removed from records

There are several buoys displaying event mode - Alaska, along the Aleutians and south of Kamchatka. Hawaii is also showing event mode.
I have been viewing the live cam 'from' the Sheraton in Maui for a while, and the water line there seems definitely to be higher than 'normal'. There are some surges almost into the edges of the resort there. Hopefully this is as high as it goes.

Re: Earthquakes - 25/05/2013 11:06

Just a few stats here for the last 7 days for these regions;

California has experienced over 950 tremors (including the M5+ yesterday) in the last 7 days.

Alaska and the Aleutian Islands have experienced approx. 430 tremors.

The Kamchatka's have had approx. 81 EQ's, nearly all M4+'s.

Hawaii approx. 21 tremors.....

Will add more soon, as my computer is playing up atm.

Below is a report by Erik Klemetti is an assistant professor of Geosciences at Denison University, regarding the earthquake swarm near Greenville, California.

Earthquake swarm, Greenville, California.

and...a report from the St. Petersburg Times regarding the M8+ Kamchatka EQ.

Kmachatka quake effect on Moscow

The Mid-Atlantic Ridge did come up with an M5+ today. There must have been a ghost with a premonition regarding the same size quake to register there yesterday, but the report was subsequently removed from record.

Also, Macquarie Island came up with another (10km deep) M5+ today.

The general Mediterranean region is still experiencing tremors, with the occasional 'offshoot' tremor being recorded in Poland, France for example.

Greece across to Uzbekistan (covering Turkey and surrounding countries) are experiencing mild tremors, with some larger ones occurring sporadically in Iran, Turkey, Uzbekistan and Kazakhstan.

The Global Incidents Map has changed and I am finding it harder to read, unless it is my annoying computer tossing up some strange lurgies.

For the moment, Duck.

Re: Earthquakes - 26/05/2013 18:51

As I had felt a few posts ago, near Easter Island has come up with an M5. As has the region above Australia, near East Timor (this quake was just south of the plate edge).
Eastern Uzbekistan has come up with an M6.
The California regions I have been watching are still rumbling with small tremors and spikes of slightly larger tremors (e.g. M3 and M3+).
I occasionally watch the Yellowstone National Park live webcam. On several occasions I have witnessed tremors going off there and today, at one point before sundown, the vents and geysers went off all over the place. At that point many of the people admiring the spectacle smartly moved away from their viewing vantage points. It looked as if they were concerned for their safety.
Macquarie Island has had several M5's in the last couple of days, which appears to me to be some quite consistent movement, which if it continues, it may gravitate towards Tassie and the SE + southern states (not sure - an amateur observation).
More soon....Duck.

Re: Earthquakes - 28/05/2013 10:50

Since my last post, the lower parts of Oz have come up with some interesting jitters on the seismo's.
Victoria (NW of CBD) and Hawker in SA (and near Adelaide? can't get up a visual of the seismo reading and exact location), and WA have shown some interesting 'spikes' and tremors, some of which have not shown up on Geoscience yet.

I actually felt a 'deep' slight rumble here in the outer east yesterday arvo. But you needed to be sitting in a quiet place to hear and feel it. I still feel there may be some 'energy' emanating from the plate movements below Tassie (Macquarie Island regions) and SW/WSW of WA and maybe, just maybe, Bass Strait.

I was just about to say that Georgia (Russia) may come up with an M5+, and as I was typing this post, this has happened.

Re: Earthquakes - 28/05/2013 23:24

Koorda, in Western Australia, is experiencing something of a quiet earthquake swarm.
I found this article regarding a study of earthquake swarms in Australia - with data relating to 41 earthquake swarms between 1983 and 2007. I found the information within this article very interesting and thought some of you might too.

School of Earth and Geographical Sciences, University of Western Australia

My feeling about this earth tremor swarm in Koorda is that it may be indicative of a potential occurrence of a larger tremor for this region. The largest tremor, which occurred in the centre of this cluster so far has been an M3+ (if I remember correctly) and there is a chance that this M3 may be the 'main' tremor, with the smaller tremors being 'for-' and 'after-' shocks. Time will tell.

I also get a feeling that the Atlantic Ocean region may come up with some moderate movements, maybe near the Canary Islands/Funchal Islands; west of Spain/Portugal?; NE of Sth. America? and/or the Sth. Atlantic Ocean. A timeframe maybe from now till into early next week - not sure about of this of course - they are just feelings folks.

There are more regions I refer to in the notes I am compiling for June for my blog. When I have finished these notes, I'll post them on my blog.

I meant to add this site from Japan, which displays all of the seismo stations in operation across their region.
If you click on a blue dot (station), information on the seismo is available. The red dots (stations) don't have current info to display.

NIED F-NET Japan

There have been, what I will term as, 'pulses' intermittently running in 'blocks' through a seismo (NE of Melb. CBD) in recent times, and in the last 24 hours. My take on this is that it could be due to shifting movements periodically occurring in a couple of our faults. It could also mean intermittent movements from a distance in the plates around Oz. Have a look here Some of the 'blocks' have been very distinctive as a pattern in the near past.
This subtle behaviour can also be seen on a couple of the S.A. seismo's too.

As I said once before, the earth is not a static entity and many of these pulses and subtle movements be par for the course for our living planet.

I wonder how they got that English list together - the magnitudes and depths, and even the coordinates are WAY too precise. Does not feel right.
Posted by: duckweather

Re: Earthquakes - 29/05/2013 21:38

Yeh Arnost, it surprised me a little too.
If you click on the links (dates highlighted) you can read the history of how they attained such info.
Considering that managing to gain the coordinates/depths/magnitudes with any accuracy is a fairly modern exercise, it is amazing how they can come up with such for dates such as those back to the 1400's.
Maybe they assessed the recorded info from those times - e.g. damage caused; what the structures were made of; intensity and behaviour of the movements generated; people lost; water/sea behaviours; land changes (landslides, splits, sinking etc.);length of tremors/EQ's; how far the movements were felt and so on......and then tabulated the whole 'picture' and compared such to the same or similar impact of today's EQ impacts.....just a guess.

I find it fascinating wink
Posted by: Xavo

Re: Earthquakes - 30/05/2013 11:45

I think you're on the money there Duck. Those numbers may very well be arbitrary numbers based on recorded damage, people's perception of the EQ (surviving diaries and whatnot), knowledge of where fault lines would've been around those times etc.

While I would take each of the older recordings with a grain of salt, I'm willing to bet they aren't too far off the mark. I doubt BGS would publish such things if they weren't comfortable with it.
Posted by: duckweather

Re: Earthquakes - 30/05/2013 12:23

I agree Xavo. For them to publicly declare such info, they would need to pretty sure of what they have written.
Imagine what Australia would have been like in the 1400's and what the native peoples would have witnessed regarding earthquakes, volcanoes etc.....I'm sure the Aboriginals may have recorded through stories and paintings some very interesting happenings.

Anyways, I have put up part 1/3 of my ramblings on my blog.

There seems to be a faint tremor (?) going through here atm. My dogs have been also standing on the edge of the decking looking south....
We'll see if this is a jitter emanating from the south, east or NE or north of Oz or if it is a local jitter.
Posted by: duckweather

Re: Earthquakes - 30/05/2013 16:38

The movement I referred to in my last post is still ongoing as I type. See this seismo example of what I have been gabbling on about. I can't provide readings from my daggy seismo - wish I could though smile
This movement has been going on for about 5 hours now.

Near Hawker/Arkaroola has just had what may be an M2+(??), according to this set of seismo's. The movement shown here seems isolated to this region, although Strathalbyn (SE of Adelaide) has had a jitter too, near the same time.

The Santa Barbara Channel, California is still moving intermittently with the odd M2+. The size of their tremors is fluctuating. This may take a while to settle and there may be a chance that they may feel another moderate quake yet.

Ok...I had a gut feeling that Melbourne's (nearby) seismo wasn't going to stay settled for long...the faint movement has started up again - seismo here
This may be short lived or maybe an indicator of unfinished business in a fault.

Just briefly for the moment (got work to do smile )
I'm getting a feeling that the movements which registered for a considerable time in the Vic seismo may crop up again today. The 'irritation' may (feeling only) be coming from the east to west, or south to north. It maybe plate movements in the south aggravating faults or something else...will see...could be wrong...

Re: Earthquakes - 02/06/2013 23:13

Hi Steven. The Australian (News) has put up, an hour ago, a report on this earthquake and its' impact on the community there. One person lost their life and many others were injured -
"Deadly 6.3-magnitude earthquake rocks Taiwan's capital Taipei "

Leon Mow's seismo has been showing some definite jitters today. At one point it played up and seemed to be recalibrated then continued on with some movements. I definitely noticed some very mild moments of small wobbles in the (water) surface of a cup of water I had on a solid table, a few times today.
Just to note - if I see side-to-side wobble in the water surface - I interpret this as being horizontal (e.g. east/west movement or SE to NW, or south to north - and so on) movement.
If I see a ripple effect - I interpret this as a vibration and/or vertical movement. The vibration may sometimes be from a distant quake too.
The wobble side-to-side can also sometimes be from plate movements at a distance - i.e. the land is moved sideways for example.

I haven't had much time to focus on EQ activity up until late this arvo, as we have had both of my boy's birthday celebrations all weekend. My 'babies' are growing up cry

Anyway, the western edges of the ROF ( including the Fiji/Santa Cruz Islands regions etc.) has/have been very active today. Where Taiwan is positioned on the plates meeting points - this point was 'jumping out' at me yesterday as being a potential region for a larger EQ.

I feel too that the British Isles is going to move again (Ireland, England, Wales and maybe Scotland) - I feel there is still some energy there to release on a couple more occasions from now...

.....just finally checked the Global EQ Map and lo and behold, Ireland has just had an M4....

See Geoscience record of these tremors here.
These tremors are close to the coast, with the Indian Ocean to the west and the Great Australian Bight to the south. There are plate 'trenches'/deviations pointing towards this region....

Also Mungindi, NSW has come up with an M3.1 (5kms deep) 7 hours ago. Info for this tremor can be found on the link to Geoscience above.

Just a quick note on OZ.
Every state/territory in Oz has come up with a tremor in the last week, particularly in regions near the coastlines.
Qld, as I suspected, came up with another tremor (M3'ish), as has Victoria SE.
WA continues to experience tremors, with the odd one gravitating towards the coast too.
SA is a place which experiences seemingly regular movements atm.
I tend to feel that our various fault lines near our coastlines, generally speaking, are being mildly irritated by distant plate movements still (and possibly a couple of other things).
Should be back to more posts with better info soon.... smile

Re: Earthquakes - 10/06/2013 12:49

Hi mysteriousbrad and other WZ'ers.
(still on friends' computer atm).
This was a good old shake for the NT, and radiating through neighboring states. It even jiggled seismo's all over Oz.
I had a gut feeling that we (Oz) was going to enter an active period. There may be the odd aftershock(s) after the main NT one.
SA and Vic may come up with some more tremors, as will WA and maybe NSW/Canberra and on the odd chance QLD.
Australia is not immune from larger quakes, through intra-plate activity. Every so often a larger quake erupts, reminding us that though we are generally sitting upon a large tectonic plate, our great land is still capable of movement in sensitive/fragile places.

Anyway, it has been interesting to observe (and feel) the movements in Oz atm and recently. There has been a bit of a strange 'feeling' in the air lately. Some of the wildlife (and domestic) have had moments of acting a little strangely (including birds in the middle of the night). Also some deep and faint 'thunder-down-under' [sounds, not what you may be thinking/relating to the water closet eek ] and the old 'water-in-the-cup' movements and slight wobbles.

Anyway, will add more very soon wink Duck.

Woken by two loud bangs at 6.15 this morning! M5.2 just off Port Vila, Vanuatu. Could hear it coming like a jet taking off! Forty five minutes later the water in the pool is still swinging from side to side! Totally different from the last earthquake which lasted longer and was silent. I did not realise that each earthquake can have different characteristics. Not sure why this is?
Posted by: duckweather

Re: Earthquakes - 12/06/2013 11:46

Hi cyclone sally,
That must have been very unnerving for you!

The general differences with earth tremors/quakes can involve the depth, composition of the structure (earth, rock etc.) of the epicenter of the quake and the surrounding land and/or sea floor; size of the 'shift'; reason for the movement; slow, gradual or sudden release of the energy (behaviour of the movement); what is powering the movement (e.g. plate shift, slip, grind, compression, spreading, ground or plate lift etc.); volcanic activity; impact (from above or otherwise) and so on.

The movement, whether it be vertical and/or horizontal can impact the nature of the resulting impact - rolling, shaking, dropping, rising, structure damage, pool water agitation, swaying, including liquefaction and so on.

The sound can come from the energy release and movements in the action of the plate, fault etc., reacting to stressors and faltering/moving. Sound is also emitted from cracks, grinds, breaks etc..
The prior noise can be sound waves proceeding, during and/or preceding feeling the subsequent movements.
Many people, including myself, have heard an EQ 'coming', as you describe like a jet approaching, taking off; a truck rumbling closer down a road or even a sudden explosion like a sonic boom.

There are what are called "P" (primary) waves and "S" (secondary) waves associated with quakes. description here Generally during the "P" wave phase (if I am correct here) one can feel a kind of dizziness or feel slightly off balance. After the "P" and "S" waves have been and gone, one can feel nauseated by degrees (some do and some don't). It can occasionally be like the effect of the 'shock' waves of a bomb/explosion going off.
This same exertion of energy leaves, for example, the water in the pool sloshing around for a while, during and after the tremor, as it has been physically moved and before it stabilizes again, the energy in the water is transferred back and forth, with the walls of the pool counteracting each bout of the side to side energy still pent up until all this energy is gradually dissipated/dispersed.

Recently, Hawaii experienced a moderated (M3++) tremor, which at first appeared not to disturb the water too much, But in the hours afterwards, I noticed sea level and current disturbances, sweeping around some parts. So after a quake has occurred, water can display various degrees of agitation, even what appears to be a 'delayed response'.

I think the loudest noises come from movements which are substantial and/or sudden in momentary release/slip/grind/break/compression (etc.).

Other 'noises' can come from magma and gaseous happenings occurring 'below', amongst other things.

Some earth movements/tremors/quakes can be 'quiet' as the movements/actions associated with them may be more 'fluid' (smoother), more 'slidy', less sudden or very deep in nature. But I don't feel I have explained this very well. I'll see if I can find out some more info...

I have jotted this rather quickly, so I may have missed some bits and I maybe wrong with my observations here and there. I may re-read this later and correct myself. wink

Cheers, Duck.

Re: Earthquakes - 13/06/2013 12:03

Just spent some brief lazy time looking up some studies/articles on the regions where the tremors/EQ's have been occurring in the NT/WA and NT/SA border regions.
One I found interesting reading and has a map of some fault lines in the NT is called "Deep Seismic Reflection Profiling In The Northern Territory: Past Work And Future Directions" - here - by R. Korsch, B. Goleby and E. Chudyk

The landscapes of these regions is very interesting. Visually, you can see a distinct east - west structuring (ridges) of the land form/escarpments.

"The Origins Of The Intraplate Stress Field In Continental Australia" [Earth and Planetary Science Letters 133 (1995) 299-309] is fascinating reading. I am going to re-read this article again to get the full gist of it.

If you like maps, like I do, here's a site with multiple maps of Oz, including a map on the Cratons of Australia - Global Security (dot) org - Australian Maps

The tremor/activity in Oz seems to have been on the increase lately......

I hope you find this post interesting smile

The M6.7, near Christmas Island and south of Java, "...is a shallow outer rise tensional event due to plate bending into subduction zone. This Oceanic plate is bending and the stresses in this plate have triggered the earthquake." source - The Watchers

If you have a look at the buoy in event mode on National Data Buoy Centre's website, click on the 'flashing' diamond below Indonesia and you will see that before the quake the readings were very jittery. I was watching this and felt that it was a prelude to a considerable EQ.

Another buoy in event mode is east of New Jersey, USA east coast. This weather system may have something to do with this buoy response - Severe weather US east and Atlantic

Re: Earthquakes - 15/06/2013 00:21

Gee..thanks for your lovely words Fyweather wink
I try, when I get time to post info, links and my own feelings (pre and post events) about EQ's and related stuff, which I hope others may find interesting and informative.
There is also alot of info I don't get to post here and on my blog, due to lack of time.
Nature/Earth never ceases to fascinate me.

I feel there are 'things' going on in the geological world (EQ's, etc.) which are 'unknowns' currently, and as you say - joining the dots, perceiving what the unknown is/maybe and marrying this with the 'known' is the challenge sometimes for scientists and amateurs (like this daffy Duck). Much of my thoughts run on intuition, rather than in depth knowledge - sometimes I can be wrong.

I feel that there will be recognition of some newer fault lines in Oz, or this could be old ones being discovered. I also get a gut feeling that what is/maybe happening 'below' with some of Oz's tremors, may begin to show surface/land signs here and there (meaning maybe observable minor ground lift or drop; fissures (cracks) and maybe inland water table/salinity issues). Now....these are feelings only, not predictions of actual events.

Good morning folks.
Overnight (our time) Crete and Nicaragua have experienced substantial quakes (M6's [+]).
The Nicaraguan quake, off shore, generated the need for a tsunami warning (potential watch only), as it was deemed that this quake may have the potential to spawn a small tsunami. I am quite sure there would have been some water level/behaviour disturbances of a minor nature.
Crete has been experiencing multiple aftershocks since their M6.2.
More news on these quakes will eventuate during today.

I get a feeling that Hawker in South Australia has just had an M3? about an hour ago. The seismo's in SA have registered what appears to be a 'local' movement, which I am guessing the culprit may be in the region of Hawker.

Hi folks. I've been busy today and am now catching up on what's been going on on the EQ front...

So for the moment, I'll jot a link to an article, titled " High-Speed Geology: Violent Seismic Activity Tearing Africa in Two" By Axel Bojanowski , which is very interesting reading and quite curiously 'answers' or confirms some of my feelings (and silent questions) I have had regarding this region.
This article is dated January 20, 2011. Though it is a couple of years old, I will see if I can find some more up-to-date info or an update on this report.

For now, Duck.

Re: Earthquakes - 17/06/2013 16:45

Geoscience has just put up on their site that EQ/tremor I mentioned in Hawker, South Australia (in a previous post) that I suspected had occurred.

Crete is still experiencing subtle then substantial EQ'/tremors. It might take some time for this region to stabilize.

Kamchatka and Japan may come up with some movements very soon.

Bit more later.....

Re: Earthquakes - 17/06/2013 20:38

Hi T.C. T/P

That is an interesting site - as it goes further than I do (a different approach) to tie in solar happenings with potential influence on EQ's. There is alot of merit and practical application in this perspective.

I am always interested in these kind of correlations and admire the work these people/bloggers put in and their focus (and the results on many occasions).

Call me an old flower-child, and some might grin , I try and stay true to my intuitive perspective regarding EQ's etc.. with a definite interest in the science perspective and the perspective of those who 'think-outside-the-square' - trying to piece the signs/signals and observable 'behaviours' of our beautiful planet (and solar) together.
I wish I had more time to be more thorough and focused on my EQ interests.

I too believe (my good old feelings/intuition) that we may be in a 'beginning' and/or continuing period (length of time??? - maybe over the rest of 2013) of some substantial and maybe impactful earthly activity. As I have mentioned in my blog, I feel that maybe water issues, meteorites, emissions from volcanoes and some powerful EQ's may be on the rise and/or intermittent features for May/June (and spaced over 2013).
There may be lulls in 'activity' which may leave many to become 'complacent' by degrees about further potential happenings. Then an event may occur to stun many or raise intense interest. (I am being deliberately rather vague here, and I don't like being a dramatist..)
The earth (and other reaches) have always done their own thing, of which we are at their mercy mostly. So what I mention is probably fairly predictable in the scheme of things anyway....sometimes I am accurate (if I may say so myself...)

Cheers, Duck. wink

Inland on the Californian coast, Mammoth Lakes (Long Valley area) in the mountain ranges, is experiencing a cluster of tremors between M1 and M3 atm.
Nearby is the Yosemite National Park and the tremors are quite shallow and not occurring near the major plates in the region.
Global Incident map - Earthquakes

This activity, which has been going consistently for the last 2 hours or so, could be a prelude to a moderate EQ/tremor or a situation similar to a recent cluster in another part of California where the behaviour settled after a day or so.

There are also the occasional small tremors happening over the border into Nevada to the east.

Hi GDL...there seems to be a few places in the US which are proving to be a bit troublesome. Some regions along the west coast, including some near shore islands; some points along the Mississippi, central south-east US and so on, are continuing to experience happenings such as sinkholes, landslides, water issues for example.
Though, there are also many other regions around the world which are experiencing interesting, horrible and some unnerving, issues too.
It all makes me feel pleased to be on what I think is fairly firm ground, even if it seems a fault line in Vic points in my general direction eek
I feel for all those folks around the world who are losing their homes (and some lives) to the issues mentioned above.

Yeh GDL...there are some amazing things in places like Ethiopia and so many others that generally we don't hear about unless we research them, like the rift zones, active geological changes and so on in Ethiopia, and the effects of such on surrounding countries and seas too...

Another thing I am discovering, when I get the time to look, is the amount of mining and sourcing of earth's riches which goes on in the world...astounding.
For information's sake, I found this blog (article dated in 2010) about the The Geology of Ethiopia - interesting..

Another interesting net info find was the Afar Rift Project - HERE . Have a look at the Y/T video which is near the top of this page - "Fast and Furious: Witnessing the birth of Africa's new ocean" - uses GeoVisionary software by BGS (good description under Y/T video on Y/T itself)

Also, I mentioned Japan may become more active again, and HERE you can see there has been a little lull movements there for about 24-36 hours, and now is quietly starting up again.

Melbourne's M1.? was sharp, short and with a 'bang' as it has been described by some...
If you are in this region, look at the sky. The clouds are very interesting and there have been some trails of sorts originating from/to that general direction.
You're probably going to think Duck is going dippy or the freezing temperatures have numbed her brain smile but here's a couple of obscure thoughts...and I am probably completely off the mark here...apart from this movement being more than likely a tremor (there has been a thought that it may have been a quarry blast), I can't get the word 'meteorite' out of my head atm. Just a left-of-centre, crazy, loopy idea, yes...
We'll see what caused the 'bang'...I may be completely wrong here...

Re: Earthquakes - 22/06/2013 10:28

Yesterday, Melbourne's outer east had an M2.2 (upgraded from the M1.5 originally reported) emanating from the Lilydale region.

As many of you may know, I usually observe clouds formations before, during and after tremors/EQ's.
Now, what I noticed from yesterday's clouds were;
1. a large fanning out of cloud from a pivotal point towards the Lilydale region,
2. A few 'vertical' clouds dotted over/near the Dandenong Ranges, due east from here, and some in the general east region, after the tremor.

For me, these clouds caught my attention. I do also understand that some may think this is a lot of hocus-pocus, and that's fine smile
This and a couple of other things I noticed dissipated as the day wore on. This cloud behaviour is reminiscent of the same sort of things I have observed before, during and after other tremors/quakes here, in Indonesia, Japan, China, Haiti, the US and so on. (My observations of the overseas countries have been mostly through photos and reports by locals and scientists on the net). I have personally seen some in New Zealand, Australia and Fiji, and when flying over the oceans towards the islands mentioned.

I am going to do a new post, with pics and info from around the globe (including from scientists + other observers), for my blog, regarding EQ/tremor clouds/atmospheric conditions before, during and after such.

Cheers, Duck.
Posted by: duckweather

Re: Earthquakes - 22/06/2013 11:51

To add to my last post, I thought I'd clarify when I saw the various cloud formations yesterday....
Lilydale's tremor occurred at about 7am. I didn't see what preceded the tremor, cloud wise. But after the tremor for many hours, there was a fan-shaped cloud formation (similar to my photo below) with the point originating in the region of Lilydale.



The cloud emanating from the 'horizon-point' were more shaped like arms, rather than feathered.

During the afternoon and late in the evening I noticed vertical clouds like in the picture below forming (a couple before my eyes) and staying in the one loctaion - not moving.



Photo below - courtesy of www.earthquakesignals.com - Zhonghao

The clouds, similar to the ones in the second photo, occurred in the direction of north to south/south to north towards/leading away from the tremor epicenter. There were also 'horizontal' strips of cloud 'pointing' to a vertical one east of here.

Now, make of this 'info' what you wish, but I feel (with absolutely no scientific qualification or proof) that the latter may have been post-associated with the Lilydale tremor. I do have further thoughts on why (fault line jitter), but I don't feel I am qualified to say so and I may be wrong with my observations.

Cheers, Duck.

Re: Earthquakes - 23/06/2013 12:20

G'day folks.
I've been watching this seismo on and off since early this morning. Why? you wonder smile Well, I had a strong feeling that Melbourne was going to continue to experience jitters in one or a couple of faults, due to the nature and number (2 so far, in moderately quick succession as registered with Geoscience, and in the general regions I have been 'observing' in the last day or so).
I had a feeling that there was/is more to come on the tremor front (even small jitters). At one point I felt that Vic may be even in for a moderate tremor maybe in the east and/or in the SW of Vic and/or on or near the border (either side) with SA.
Anyway, will wait and see if any more jitters do occur in the next 24 hours or so.

Cheers, Duck.

Got home just in 'time' to witness Benalla's tremor happen in the east - Geoscience
As I said in my last post, I felt that the east of Vic was possibly going to experience another tremor - I felt the 'signs' were there.
The ground here was ever so faintly moving (extremely subtle rocking) just a few minutes ago. You had to be in a very quiet place, watching the surface of a full cup of water.

Another thing I noticed this arvo, was a huge expanse of ribbed clouds to the SW.

There may be a chance that we haven't seen the end of tremors in Vic. Just maybe.....

Sorry South Oz and Canberra/NSW blush I meant to add in my last post that you too have been experiencing some movements as well, particularly Mt Rat, Robe, Strathalbyn, Adelaide and a couple of others which have skipped my mind atm.

It appears that this EQ registered slightly on our seismo's in Oz...example here

Re: Earthquakes - 26/06/2013 22:10

There seems to be a notable increase in tremors in the general California regions, Nevada and down to near Brawley (lower California) - 100 in the last 24 hours as recorded by the USGS

I have noticed that there has been a subtle increase in tremors in the mountain ranges, into Nevada for example.
The San Andreas Fault (between Los Angeles down to east of San Diego) has had (and is) a 'cluster'; then sporadically dotted up the coast, inland and further east (an increase here) associated with other lesser faults.
This increase may be a precursor to a larger movement for California or Nevada. The youngest tremors being NW and west of Las Vegas (into California) - 4 at time of typing this post.

Tasmania, WA, SA, NSW and Vic have been quietly (and a few noticeably) rocking away in June. As I said in a recent post, I feel that further movements may occur in these regions and we may see a moderate movement (M3+?) in the very near future. I have a feeling this could be in the south east of OZ, but could be wrong. Just regarding my region, I have heard some very low tone sounds emanating from down under (ground) and the faint vibrations here and there.
There maybe a moderate movement west of Tassie and maybe west or SW of WA (offshore for both states).

For the moment, Duck.

Couldn't edit the above post...
Was just watching Yellowstone webcam HERE and saw the camera rocking around quite a bit. Seemed like a moderate movement - will wait for the USGS to see if an M3(+?) has registered there.
From my understanding (general), after you see this kind of rocking occur, the geyser lets fly with an awesome 'spout', and several others nearby...

Posted by: duckweather

Re: Earthquakes - 27/06/2013 20:00

In noticing Indonesia's M6 tonight, it got me thinking again about how and if large EQ's can trigger other tremors or quakes locally and even worldwide.
I personally believe that they can, if in the moment of the large quake, a region or location (fault known or unknown) is positioned or ready to absorb or be triggered by the energy emitted by the large quake.
The ripple effect or waves (energies) thrown out and beyond the large quake can trigger further destabilization of a location just needing a kick (of needed size and power) to set it off. The resultant movement may be unnoticeable to us, or could range through from slightly felt to definitely noticed. Where the nature and amount energy is dispersed may depend on what this energy travels through, e.g., water, type of earth, rock etc..
I also think that one quake may cause destabilization of a known/unknown fault on the odd occasion.
But like with an atomic bomb going off, the atmosphere above the epicenter and below (underground) the epicenter are also affected.
Though having said all of the above, it doesn't mean that every time a large quake goes off that every fault is affected.

Here's an article from September 2012, which discusses the M8+ earthquake that rocked Sumatra last year - "huge Earthquake Triggers Other Quakes Worldwide" - Live Science

But here is another obscure thought...some quakes, even seemingly distant from one another, may also be connected geologically/physically...and/or when one side of a plate (for example) moves away or 'pulls away' from one region, that its opposite side may also be affected by a push or squeeze...or maybe put increased pressures on the dynamics of one plate sliding under another.....?
I also never discount the possibility that one end of a fault line experiencing a jitter/movement - causing a tremor/quake, may correspond later or simultaneously with movement at the other end (or along the line of the fault). This is appearing to be happening on occasions along the fault line(s) running up and through California as an example.

With Victoria's recent tremors in the NE/E, I have a gut feeling that these two tremors (which happened in fairly quick succession) were somehow related to each other....but folks...I could be wrong...
I am also going to go out on a limb here and say that I feel that a fault running south from the Lilydale tremor region may have been niggled slightly....? I am happy to be corrected here by someone who knows a heck of a lot more than me about Geology wink

Gee I rattled on a bit...

Posted by: duckweather

Re: Earthquakes - 28/06/2013 22:33

grin Petros, cheers to you.

There are some scientists (in several genres) who think the cloud theories are just hocus pocus (as I eluded to in another post). But there also a good number of those in the science field and those, like myself, who do feel such natural signs exist. The 'art' is in trying (well for me at least) to differentiate between the various normal cloud formations and those that seem to behave in a different manner. Nature does 'give off' many signals and the other 'art' is in recognizing, observing and reading them.

Such observations of the natural environment have been 'around' for possibly thousands of years. It is not 'new' science...and I love a challenge and am one of those characters who likes to think beyond the square (of the 'known' vs or complementary to the 'unknown').

Just maybe, what currently for some may be dismissed as not feasible as true science or within the bounds of current teachings, may one day be a part of natures messages which is like the unopened letter from that person whose mail you didn't want to read in the past.

Thanks for lurking Petros and commenting wink

Thought for others who may be worried for friends and/or relatives is an ever present awareness of mine whenever I discuss EQ's. I too have had friends caught up in situations where problematic EQ's have occurred and when getting in touch with them is difficult to begin with.

EQ clouds?? Currently there is a rather large stretch of these (maybe) types of clouds from just NE of Port Augusta - to the Vic border to the east and down the border with Vic/SA. In other words, the SE corner and into Victoria SW.
If you watch them on a moving sat pic, the clearings between the cloud 'ribs' is somewhat stationary....
Here's the EQ cloud idea in visual experimental mode for the moment.
A Chinese scientist believes that these sort of clouds may indicate future tremors from 'now' and for (?) the next couple of months....we'll see...
I have been getting a feeling anyway, that SA will continue to experience small tremors - I feel that this region is somewhat unsettled.

Re: Earthquakes - 05/07/2013 20:55

I've been watching the buoy readings for the buoy situated under Java, Indonesia, in the last few days.
As I said a couple of posts ago, I felt that this exact location was possibly going to experience a moderate EQ and unfortunately it did an hour ago.
The mid-Indian ridge also came up with a moderate EQ too 4 hours ago. SE of Yemen and maybe more south of the Mid-Indian Ridge EQ location may come up with some movement too...could be wrong.

The far NE tip of Vic/far SE corner of NSW came up with a small tremor off shore today too. There are sea floor 'deviations' here, before the shelf drops down to the deeper ocean. If I am correct in my observations here, I think that a Vic seismo is still 'niggled' slightly (showing subtle constant movements) since this movement and the EQ in the Solomons. Leon's seismo - Vic

California - Los Angeles had a cluster of continuous small tremors today. This may be a precursor to a further movement (M3+?) maybe towards San Diego and/or Baja, California....?

For the moment, Duck.

Good morning folks.
As many of you are aware, New Ireland PNG experienced an M7+ this morning and there was a subsequent M6.5 just west of this location in New Britain PNG one hour later.
The first EQ was very deep, and though no tsunami warning was issued, there must have been some sort of water disturbance. In my mind, if 'it' rocks the ground, it also disturbs everything else by degrees.
To look at the USGS info on both quakes (and others in the world), scroll down the list to the left and click on the locations for info - here

I had mentioned on my blog, that I had the number 7 (and multiples of, e.g. 7/7, 777, M7 and so on) sticking with me on 6/7 (our time). Maybe just coincidence...

There may be aftershocks from the PNG EQ's or transference of energies to some other regions near this part of the world.

For now, Duck.

The south of Java, Indonesia's M5.8 (51 kms from a volcano) has set off a buoy- see the National Data Buoy Centre It is showing a reading 'drop' off 150 metres.

There have been a succession of larger quakes since PNG's M7+ - maybe this was what was inkling me 2 days ago as to the multiple '7's I was getting a feeling for (obviously they are not all 7's). Hope this doesn't mean too that the eventual count of these quakes is 7.

Posted by: duckweather

Re: Earthquakes - 08/07/2013 21:55

I had a gut feeling TC that there was going to be a kind of global effect set of movements.
The depth of the PNG movement and the like, are like rattling the foundations of a building - the rest of the structure may be impacted to some degree - degrees depending on points of vulnerability, obstacles (perhaps absorbers and/or deflectors of waves of energy, composition etc.)
Vulnerable points maybe 'sensitive' faults etc..
By composition I mean for example, in an earthquake, soil/land composition can mean the difference between mild to severe damage. If I remember correctly, areas of softer soils (or of varied composition) for example can experience more damage to structure/surrounds/peoples than an environment composed of, for example solid rock. (I may need to re-read the science on this one).

In a rough relation to the potential of a really deep rattler like PNG's M7+ - the dynamics of the movement (causes and subsequent action) may also be indicative of a non isolated (to this region) set of energies being released on somewhat on a scale beyond this region. An energy of any kind has a driving (or pulling) force somewhere...

One earthly dynamic which can interplay with movements of course, are volcanoes/magma movements. I wonder if a large movement like PNG's, is a trigger (by degrees) for increased volcanic activity?
The SW Pacific region (and NW and north of the Australian land), for example, has thrown up many larger movements in recent times and it makes you wonder what is going on down there - meaning I wish I could actually see (get a first hand look at) the changes happening (just my curious mind).
Obviously there have been other regions, like Japan, which have experienced dramatic movements too.

Anyways...with all the movements today, I'm starting to wonder of the Gulf of Alaska or the coast of California or the region of off-shore Canada may experience a larger movement too.....?

OOps, I've rattled on again smile

Earthquakes, Headaches, Human and Animal Behaviours

For this post, I thought I would do something a little different.

Around the world, many individuals report disturbances in hearing/ear tonal noises, headaches, equilibrium issues, feelings of vertigo and even various levels of anxiety. Some have also described mood changes and an odd feeling of impending doom in a hand full of others.
One thing, which some find difficult to dispute and others may discredit as reality, is a basic natural, instinctual intuitiveness to sensing changes (many unseen) in the environment. If one is not absorbed with constant clang of daily life continually, which can be difficult depending on your personal circumstances, and is able to take a step back from ‘life’ and connect with and observe the natural environment, combined with our own natural instincts regarding shifts in energies, various subtle or obvious signs and signals around us can be observed.

Another observation of the ‘natural’ environment, which many has discussed in many parts of the world, is the reaction of animals to change in the environment. Some species have emerged from below their underground havens on mass, to the amazement of us humans in some cases. Some sea-life beachings have appeared to coincide with earth and under-sea movements and many dogs, cats and wild creatures’ behaviours have seemingly become erratic, unusual and some have displayed distinctive anxieties before the occurrence of an earth tremor or quake. Have you noticed the bird chatter in the air become almost silenced before a nature change occurs? And, sometimes animals migrating locally or to a distance prior to changes in the environment? There are many and varied reasons why fauna behave the way it does, but unusual behaviour is usually a signal of impending change, which if one is attuned to such can recognise in the moment.

But what is it that possibly causes all of these varying degrees of human and animal emotional and physical disturbance and altered behaviours?
I personally have always believed that the earth emits its own signals, such as electromagnetic fields, the odd stream of condensation from fault line disturbances, atmospheric disturbances, sound and energy waves and so on. Earth’s creatures are usually the first entities to register such changes and it can be our inadvertent or focused recognition of such behaviours which may, in some cases, warn us of a tremor, or at worst a larger earthquake scenario. Being tuned in to our own physiological ‘signals’ can add to an overall perception too.

Apart from this topic being avidly discussed on forums and elsewhere on the internet, scientific studies have been done on this phenomenon. Examples of such research papers can be found in the International Journal of Biometeorology, such as;
“Disturbances in equilibrium function after a major earthquake”
link http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3475992/ (by multiple Japanese authors)

“Headaches prior to earthquakes” – by L.L. Morton
link - http://link.springer.com/article/10.1007%2FBF01044909

Another interesting article is;
“The use of animals in earthquake prediction” - by Dr. George PC (China study)
Link - http://rense.com/general61/use.htm

Sometimes I experience the kind of feelings of ‘pressure’ in my ears before large earthquakes in or near Australia. Before, as an example, PNG’s M7+ a couple of days ago, my ears had that feeling of pressure (like the ‘ear-blocking’ sensation-change in altitude) in the hours before this quake happened. I have experienced this on several occasions, though I don’t claim this to be absolute proof of an impending earth movement of course. Vertigo, on occasions, adding to the equation has left me with headaches (like the one I have now).
Before, during and after our Melbourne (Australia) M5.3 some time ago, I experienced all of these things, as well as a dizziness as the “P” shockwave passed through just before the rattling of the quake (“S” wave) began.

Anyway, I hope you found this post interesting and it is certainly only a brief chat about this topic.
Cheers, Duck.

Posted by: duckweather

Re: Earthquakes - 11/07/2013 20:04

Well, so far Geoscience hasn't recorded anything for what I thought may have been a Gippsland movement.
The seismo which has been showing these interesting movements is based in Narracan, Gippsland - here - the NARR c readout.
This reading has shown some prominent spikes, with movements building up to the main spike, then tapering off in decreasing jiggles post this movement. So if nothing is coming up with Geoscience (and Petros didn't feel anything wink ), I am a bit tossed with what caused the spikes. Generally, they didn't seem to correspond with a non-local movement.

For now, Duck smile

re: sonic booms and supershear earthquakes
This sentence I found interesting and 'confirms' some queries I had in a discussion with someone recently regarding the ends of fault lines behaviour when stressed.

Also, I've communicated with Ms. Milo and her brother was safe and sound in Indonesia after the big quake recently wink

I have been feeling in the last few days that Between Vic and South Australia (either one) a moderate tremor may be brewing....don't take my word for it though...it is just a feeling only. When (and if one occurs) - I'm not sure....the feeling I am getting is of an energy running east to west (from Vic to SA) and south to north (east of Melbourne)....we'll see...

Well folks, here is the energy starting to go through our seismo's (in the last couple of hours) which I mentioned, yesterday, could begin/occur soonish - seismo's s88U c and NARR c
My gut feeling seems to be right about such.
What is creating it could range from Vic fault tensions or tensions in a plate boundary or trench, for example.

Re: Earthquakes - 14/07/2013 20:01

I came across an article on news.com.au which discusses fracking, EQ's and how distant large quakes which may disturb fault lines at a great distance from such. Much of the article 'confirms' my long held suspicions about man's actions in sourcing the earths' resources....
In one paragraph, mention is made that fracking induced tremors are not strong enough to feel. Now, I don't get into the 'politics' of things like this, but I tend to disagree with this - just ask the folks, for example, of a few of the southern states of the U.S....
Anyway, here's the link to the article, which is dated July 12th 2013

Also, on my blog, I have added earlier today some more 'notes' for July. I noticed Alaska has had a couple of moderate quakes - which I have mentioned as a region for a potential moderate EQ.

Re: Earthquakes - 15/07/2013 13:50

On the odd occasion a negative magnitude (e.g. M-1, M-2 etc) is recorded here and there.
I often wondered (being an amateur) how the heck could a tremor register a negative reading?
Well, I found this explanation of negative readings by a blogpost on the Pacific Northwest Seismograph Network site -

Quote:
Back in the day (1930s), magnitudes started as simply the logarithm of the amplitude of the largest oscillations written on a specific seismograph at CalTech (a Wood-Anderson torsion seismograph measuring horizontal motion, if you must know!). The instrument Charles Richter used was the standard. Really for no other reason than that he had it and so he used it. He used the logarithm of the amplitude because there was such a large range of amplitudes that the compression of scale you get from taking logs made things easier to plot. Some darned earthquake that was 100 km away, made a trace with a peak displacement of 1 mm on his seismograph and he called that the standard earthquake--magnitude 1. An earthquake at the same distance that made a displacement of 10 mm was a magnitude 2, 100 mm was magnitude 3, and so on. "Smaller" earthquakes closer to the lab or "larger" earthquakes more distant might produce the same peak amplitude, so the formula includes a distance correction for earthquakes not at the standard distance. This explains an enduring mystery to many folks--negative magnitudes. An earthquake that wrote a record with a peak displacement of 0.1 mm would be a magnitude 0, right? And if that earthquake were farther away than 100 km, well ... it would have a negative magnitude. Remember: Magnitudes are a relative size estimate. Nothing absolute about them (but, perhaps, Charlie Richter's arbitrary "standard" earthquake and seismograph); no physical units ascribed to them.



Interesting....

Well, well...I have just got back from driving for 2 hours. Just before I left, I was honing in on King Island in Bass Strait on Google Maps, as this region was niggling at me for a tremor today. And, an M3+ has come up 117 minutes ago.
I mentioned this on my blog yesterday as an area (Bass Strait) which may experience a tremor. That energy I kept harping on about was emanating (resonating with me) was from that region - the south to north I was gabbling on about.
I could feel it in my bones you could say - here is the link to Geoscience for this tremors' details

Curious, and will see if this affects any movement in the Selwyn Fault...will have to see....

Japan region - Southwestern Ryukyu Islands hit by 4.8 and 5.4 magnitudes

Just in - Samoa Islands region reported in with a 5.5 magnitude near Apo

And finished up with a 5.1 mag onland in the Dominican Republic and a 7.2 magnitude off the South Sandwich Island region
Posted by: duckweather

Re: Earthquakes - 16/07/2013 11:58

Yep TC, there has been a 'run' on this activity.
The Sandwich Island M7+ was a strike/slip movement at a fairly shallow depth. This is apparently near where the South American, Sandwich and the Antarctic plates interact in a varied behaviour of movements. It doesn't appear to be volcanic related. The nearest volcano, if I remember correctly, is about 171kms from the epicenter of this quake.

Most of the quakes in the last 24 hours have been plate related. Though there are many tremors emanating from volcanic activity atm, in their local vicinities, as well as fault jitters.

I still feel that Alaska is unsettled, as may be the west coast of the U.S. (California). Offshore Canada (maybe near the Queen Charlotte Islands) may show some activity too....?

The north-of and south-of regions of the Himalayas are sticking with me little atm. I get a feeling of a north 'push' up the the India region from the Indian Ocean (northern reaches), into China, Afghanistan etc..

Re: Earthquakes - 16/07/2013 18:05

What appears to have been 'going' all afternoon is a vibration (with slight variations in intensity) running through Vic and SA.
I was watching the Gippsland seismo's movements on an off for a while, then it went off line (Peeking Duck must have cooked it smile ) . So if you have a look at this Morphett Vale (South Oz) seismograph readings , you can see the 'energy' I am referring to also going through Vic. If you refresh this seismo, it updates - or it appears to auto update on this website - here. Also on this page, there are many other seismo's dotted around Australia, which you can observe.

I am not sure if these movements are reverberations from the South Sandwich quake or whether Bass Strait/Great Oz Bight is gearing up for some sort of movement...time will tell.

Cheers for now, Duck.
Posted by: Petar @ Sdny

Re: Earthquakes - 16/07/2013 20:51

Hi Duck,

I agree with the movements are reverberations from the Sth. Sandwich Islands quake. In the last 6 hours we have seen moderate quakes/tremors in areas not notable for tremors:

3.8 in western Lithuania
4.3 in Western Sahara

Just had two stronger shakes in the last hour, 5.9 mag near Solomon Islands/Bougainville and a 5.3 magnitude onland Taiwan.

Uptick in progress
Posted by: duckweather

Re: Earthquakes - 16/07/2013 21:50

Hi TC wink

My radar may have been off regarding where a possible 'energy' was coming from...maybe the M7+ rattled the 'house foundations' (earths' crust) and the vibrations (which are still happening) are also related to the movements in PNG and Taiwan.
It almost feels like that anything (tremors) can pop up anywhere (like remote detonations) at the moment. We've seen some big quakes lately and it makes me wonder if another big movement is just around the corner - as in this beautiful planet has some unfinished business....(not meaning to be dramatic here).
I still have a feeling that Bass Strait may jiggle again. But with the headaches I've been getting with sinus lurgies at the moment my radar (as I mentioned above) may be misfiring crazy
We may see some more tremors pop up in unexpected places and some new fault lines will be discovered in some places over the next few months around the globe.
I am guessing that some of these moderate to larger movements may even create a few occurrences of new sinkholes in some parts of the world too.

For the moment, distracted Duck....
Posted by: duckweather

Re: Earthquakes - 17/07/2013 21:35

There have been a number of moderately sized tremors around the globe today.

Peru's M6+ was in the vicinity of a volcano and apparently several people were injured and about 20 houses were reduced to rubble.

Northern Alaska experienced the moderate quake I felt it would today.

Algeria's M5 was quite shallow and may have caused some damage/problems for the folks there and their dwellings. It is a well populated region and info may come out on the possible damage this quake has caused...hopefully little. Some people have reported strong shaking, some saying up to a minute/some less.

One earthquake I was drawn to today, was the M5.7 In the Shetland Islands (off shore), not far from Palmer Station (an American research station, which may only be currently populated by about 20 or so people, and has very established buildings). This quake followed on from the quake near the South Sandwich Island regions, along the same plate edge. All of the islands in the vicinity felt this quake - registering with the USGS a level "shake map V".

Japan had an M5.3, which is a reasonable size and near a subduction zone.

My info above is moderately sketchy, as I have been quite busy today, so haven't had much of a chance to look into any of the quakes with much depth.

For the moment, Duck.

Re: Earthquakes - 18/07/2013 11:43

Given that my daughter has friends in Arkansas, I have been watching this region of the U.S. for some time now.
Arkansas (and nearby Oklahoma) have been experiencing moderately regular smaller tremors recently. Today an M2.4 and M3.3.
I stumbled across this article referred to on one of my other fave sites - The Watchers. Here's the article on Arkansas fault line of concern (article dated March 10, 2011).
Without any prior knowledge of the info in the above article, I have long suspected that this fault line is longer than it was previously thought to be. I also get a feeling that this region may one in the U.S. which may produce their next moderate tremor/quake this year. Let's hope I am wrong.

(Your gonna get sick of me saying this) Some of the Melbourne and S.A. seismo's are showing increasing subtle movements on them, for example;
Melbourne Uni Earth Sciences
Morphett Vale
In my limited chance/time to check some other Oz seismo's, this seems to be somewhat concentrated to the southern portion of Oz. Though, a couple of other seism's in Qld and WA seem to be agitated too - this may be because of the north of Oz (Indonesia for e.g.) plate movements and the SW and Indian Ocean (and NW of Oz) activity.

In the short term, I feel the moderate (M5+) movements across the globe may continue to pop up.

Hawaii's tremors may be due to volcanic activity and I also feel that this region may experience an M3(+?) soon. Today they had a small run of minor tremors which may indicate the possibility of further tremors....

There are some problematic volcanoes at the moment. For example Japan, Ecuador, Alaska, Guatemala, Mexico, New Zealand, just to name a few, are producing associated earthquakes/tremors in clusters and some intermittently.

For now,
Duck.

It is interesting mysteriousbrad. Tennant Creek is considered to be an earthquake hotspot by Geoscience - here's an article regarding considered hotspots in Oz - Here

Now here's a curious thing too - last night I was reading through a text on Captain Cooks' voyages in the Pacific, where he had set off from New Zealand. At the same time I was honing in on Cooks Strait, between the North and South Islands of NZ. This is where I was not only drawn to this region regarding tremors, but this correlated with the text I was reading how Captain Cook was the first European explorer to sail through this Strait. Maori legend has it that, according to Wikipedia,
Quote:
Cook Strait was discovered by Kupe the navigator. Kupe followed in his canoe a monstrous octopus called Te Wheke-a-Muturangi across Cook Strait and destroyed it in Tory Channel or at Pātea.

Anyway, my reading of the text and honing in on Cook Strait on Google Maps, and Cook Strait having experienced an M5+ today may have just been a coincidence and maybe not some premonition.

Well this'll be my third post for today smile

That M6+ in Iceland is a bit of a mystery. I have done a quick check in the Icelandic news sites and elsewhere, and I can't find any further info on it...curious.

So far in the last 7 days there have been (according to the USGS site) 71 M4.5+ earthquakes around the globe. This does not include Australia's M4+ recently and probably a couple of others registered by other agencies.
There has been (and is ongoing) a real uptick in the number of moderate to larger EQ's lately. Mother Earth has been doing some serious re-arranging of the furniture (including volcanic activity).
See the USGS map here and refine the list to 'past 7 days - M4.5+'.
Much of the larger activity has been on the western side of the ROF (near Australia, Indonesia, up to Japan, Malaysia and down to New Zealand, generally speaking.

With all of this activity, I get a gut feeling we may see an M6+ (maybe an M7+) somewhere...not sure where yet.

Island life is so unique and different to 'city' life. There will be many things you may miss about Vanuatu when you get back to Gladstone.
The earth movements 'up' your way have been quite consistent and, as you say, you do get used to something if it happens often enough. This is also how some of my friends in NZ, the U.S. and the Mediterranean/Middle East regions feel too. Though, quietly, some may rattle or unsettle the nerves a little.
I have a couple of family members in the Galapagos Islands at the moment - a region which is experiencing sporadic movements lately. I must admit, though they are on an expedition which I wish I was on too, I'll be happy for them to come home to the relative terra-firma of Oz. Two years ago they were in the Antarctic - and they 'forgot' to take me grin
Anyways, The energy from the ROF (west) seems to have traveled south (past NZ), near the Tasman Sea and may or may not shift west to way below Tassie...not sure.

For now, Duck.

Obscure feeling for today - Scone region, NSW.
I was discussing a Canberra seismo with a friend today and I kept getting drawn to the region near Scone, west of Newcastle for some reason. Now, don't take this as a prediction of a tremor for this region. As I always say, my jottings are just feelings only. But I do get a small feeling that a fault line there may or may not be sending off some 'signals', maybe for a small movement. I may be wrong folks.
SE of Port Augusta, S.A., is another spot too....
Also, I was going to say Papua, Indonesia, was a distinct possibility and it has just come up with an M5.2.....

Re: Earthquakes - 21/07/2013 12:04

York in WA came up with an M2.6 today. Yesterday, this was one of a few regions I was suspecting may experience a tremor and didn't mention it here. From now on, so I don't look like I am mentioning these feelings for regions after the fact (after they have occurred), I will jot them here as I may begin to suspect they may occur (for credibility reasons smile )

Cook Strait in New Zealand is still presenting as a bit of a problem, with deceasing in size and increasing intermittently with tremors/quakes. The Seaward Kaikoura mountain Range (and the ranges further inland) run SW to NE along the South Island, towards Cook Strait. A valley, running parallel between the ranges leads almost straight to where these earthquakes have been happening in the Strait. The plate edges run through the Seaward Kaikoura Mountain Range and comes out into the sea, with the EQ's being about 50-75 kms north of the plate edges/trench. The trench near the quakes is associated with the Kermadec Trench.

As I am typing this, Italy has come up with an M5 as I felt it would (blog).

I'll gabble on some more later. I've got a cracking headache (ear) atm and will catch up with some more jottings soon sick

For now, Duck.

Funny you mention that, there's just been a big quake just off the northeastern coast of NZ's South Island at 3:09pm AEST, prelim mag 6.9 and depth 10km.

Unknown yet whether a tsunami was generated but here's a precalculated scenario run by JRC modelling:

Re: Earthquakes - 21/07/2013 18:04

Hi Ken.
As I mentioned in a previous post, I felt there was possibly going to be an M6+ or M7+ in a region in the very short term and New Zealands' Cook Strait has produced a doozy for the folks there. I was thinking to myself (through the fog of a rotten ear problem) that with the Cook Strait playing up that this may be just the region for the M7'ish that was irking me.
Here's a couple of links to responses from the NZ folks and other info on the quake;
Responses and info

Info from the USGS

When you consider the relatively small gap (the Strait) between the North and South Islands, I can't help but think of the impact or result of these movements in the sea floor...as to what has happened down there? This is some serious movement...

For now Duck.

Curiously, about 40kms NE of Newcastle and Scone has just come with an M3 in the last hour. Last night I mentioned my feelings for a small tremor occurring in the region west of Newcastle and near Scone. I was 40 kms off in the wrong direction, but I suppose fairly closish, with this tremor being near Tea Gardens (40kms approx NE of Scone/Newcastle).

Hi Duckweather

I live in Tea Gardens and i can honestly say i did'nt feel a thing at the time, but did hear a unusual rumble like thunder at the time, but didnt take too much notice and put it down some fighter jets playing out to sea!!

Its all over Facebook and all comments so far there are that no one else seems to have felt either!!

I will keep you posted if i hear anything else!!

That's interesting EddyG.
Thanks for posting what you noticed about this tremor. I personally always like to know what people actually experience when a tremor is registered - just my curious mind.
I will be interested to learn more about this 'M3' too.
Keep us posted wink
Cheers, Duck.

Ooh, hang on a minute, just had another obscure thought (and I mean really obscure)....I wonder if possibly no-one felt this movement beneath them, that could this be in any way related to New Zealand's larger quakes today (geo-sound waves perhaps)...?????
Posted by: duckweather

Re: Earthquakes - 22/07/2013 08:38

Just following on from my way-out obscure thought about 'geo-sound waves' as maybe a reason for the registering of an M3 in Tea Gardens......
If this was at all a possibility, here is some more obscure thought....it takes about 3 hours (?) to fly to NZ from Sydney. Cook Straits' M6.9 yesterday occurred 3 and a bit hours before the Tea Gardens 'tremor' registered. Could a sound wave travelled below or above sea level from NZ....???
Maybe I have got too much time on my hands at the moment nursing my ear problem sick maybe I should sign off here as 'Dippy Duck' smile
Anyway, Cook Strait is experiencing almost continuous aftershocks, some nearly every few minutes and many are between M2 and M3 (some may be smaller). This region is a little on tender-hooks at the moment - some are wondering if there will be another large EQ to come. This region is quite unstable at the moment.

For now, Dippy Duck.

Just looking at Geoscience website and now they have positioned the epicenter of yesterdays tremor in Muswellbrook, NSW. This is exactly the location where I had mentioned my feelings (a few posts ago) of where a tremor may pop for NSW.
So...maybe my 'theories' in my last posts can be disregarded.

Re: Earthquakes - 22/07/2013 14:09

It's a bit of a day off for me, so I may bore you with a few posts today smile

A seismo, just north of Melbourne has registered a small spike (maybe an M1+ (M2?)), and the Gippsland seismo has slightly jiggled with this also. So we'll see if Geoscience registers it as anything notable.
Last night, whilst standing on my decking gazing at the moon (it looked big and beautiful), I turned to go in my back door and the door shook/rattled for about 1 second. It is a heavy glass door with a security door as well. It stopped me in my tracks, thinking we may have had a small jolt, but there was nothing on the seismo's. Even the dog was looking at me bug-eyed. I still don't know what it was, as the whole house was quiet and I was the only one home at the time...

There has been a lot of larger movement around the globe - "Mother Earth's unfinished business" as I said in a previous post. I get a feeling we may have a few more larger movements to come - some of the recent movements (EQ's) have been quite strange...

Cheers, Duck.

Re: Earthquakes - 22/07/2013 21:35

We have now had 5 lots of 6.0 magnitude + in 48 hours. I am thinking Kermadec Islands region may get a even bigger quake next few days with the asymetrical migration northwards along the Kermadec trench.

The 6.3 mag off Prince Edward Islands is a eye opening one too.
Posted by: duckweather

Re: Earthquakes - 22/07/2013 22:00

I agree TC.
Some 'energy' may move towards the Gisborne region (i.e. NE of the North Island) and onto the Kermadecs. and maybe SW of the South Island (near the Tasman Sea). Then maybe before or after this possible movement, Tonga/Fiji/Samoa region/s and maybe back west through to PNG/Indonesia. Now, maybe only two or three may come up with a moderate tremor (maybe an odd larger one). And a northern one of these spots may come up before a southern'ish mentioned one.
Macquarie Island may experience a movement too.
Across the Pacific (eastern side). I am also wondering if Easter Island may experience a movement too.
The South Sandwich Islands may even come up again too...???
Just some quick thoughts for the moment....
Posted by: duckweather

Re: Earthquakes - 22/07/2013 23:22

Mmm...I had a wee feeling that the energy from the M6+ in the Prince Edward Islands region may travel up towards Madagascar. An M5 has occurred in the south Indian Ocean, SE of Madagascar.
I was quietly hoping it wouldn't, as a couple of my family members are in/on this region atm...

Posted by: duckweather

Re: Earthquakes - 23/07/2013 11:15

Yeh T.C...and i reckon that this region will take some time to settle. I do get an irking feeling we may see another (or a few) more moderate EQ's there unfortunately.
The SW of Liberia, Africa, which is experiencing multiple M5's is the exact region I suspected would move (blog - June notes). These quakes are situated along plate boundaries which involved yesterdays' big quake much further south. The 'energy' seems to have run up through to here. Maybe following up through the Atlantic, there may be more to come. West of Spain may be a region I'll be keeping an 'eye' on and maybe the Gulf of Guinea.

The 'energy'/movement translated up the west of the ROF beginning a little further north than I had mentioned it may. The Pacific islands (regions near Fiji/Vanuatu/etc..) may yet feel some movements too.

Kamchatka, Russia, and west of the Aleutian chain may also experience some movements soon.
The west of Eureka, California, is still sticking with me a little too.
We'll see....

For now, Duck.

Re: Earthquakes - 24/07/2013 13:59

And the movements begin in earnest along the Southern Pacific with current and recent action. Notable 5.8 magnitude followed by a 4.9 magnitude South of Vanuatu and recently a 5.6 magnitude off the Fiji Islands.

Solomon Islands also showing a rise in activity too.
Posted by: duckweather

Re: Earthquakes - 24/07/2013 14:29

Hi TC.
A quick note-
This movement is actually occurring in a sequence as I thought it would (previous posts). Meaning, that the large movements (and ongoing rattles) in New Zealand, and involving the ROF, could follow on with movements popping up in northern reaches before the 'central regions' (Fiji, Vanuatu etc.) may be triggered into moderate movements again.
I agree that the Pacific Islands regions ('central' section) have revved up again. The Santa Cruz Islands, being a region that was recently (months/some weeks ago) behaving like the Cook Strait in New Zealand is now - large, moderate and smaller quake clusters - may show some aggravation related to these newer movements in the 'central' parts.
There are some quite vulnerable (to being affected by larger movements) areas on the planet at the moment. The Atlantic, Mediterranean, Indian Ocean, Japan, western Pacific (side of the ROF) for example, and even the lower central regions of the U.S., may be vulnerable to being problematic this year/month/anytime soon.
But, there has been a noticeable uptick in earthquake and volcanic activity, with such activity having increased by approximately 10% (I need to confirm this with another site that is full of great stats) in some regions since 2012.
Anyways, for the moment,
Duck.

Re: Earthquakes - 24/07/2013 21:01

A buoy near the Dominican Republic is in event mode. There have been tremors there, e.g. M3.2, but you may think that this movement possibly wouldn't be enough to set a buoy off. There is a tropical depression heading their way and a forecast for 120 hours out from now, this will impact the Dominican region.
See NOAA here

Another buoy is in event mode west of the Gulf of Alaska, but unless I've missed something today, I don't think there has been a tremor in this exact spot today. It could be movement that hasn't registered yet. See same link above.

Re: Earthquakes - 26/07/2013 21:22

Ah, I was waiting for you to reply Petros wink
This movement on the seismo happened at about 9.30 am (roughly) this morning.
There was also a small jiggle on a seismo north/east of Melbourne this arvo.
Sometimes spikes on seismo's are due to distant quakes (but I checked for other movements on other seismo's here and afar, and there were no reported tremors to correlate with the Gippsland seismo movement). Sometimes it can be other things affecting them like re-calibration, thunder/lightning, explosions amongst other things. Sometimes too, it can be earth movements not registering as earthquakes/tremors.
Still nothing has come up on the Geoscience site, and I'm sure that if it was a bone-rattler, we would have seen it talked about on Facebook etc.. But I'd like to know what caused this considerable action on the seismo - it looked like a tremor (type of behaviour) to me....

Just for interest sake, I found an article titled "A Detailed Assessment of the Korumburra Earthquake Cluster, 2009" which mentions;

Narracan Block, an uplifted block between the Bass-Almurta Fault and the
Kongwak Monocline (Figure 1). Both faults are considered to be

I have been rattling on lately regarding some jiggles, jitters on various Australian seismo's and some feelings of where movements may have occurred. I generally rely on the Geoscience site to verify any of my suspicions of movements in Oz. But, unfortunately I can't check the above at the moment, or there haven't been any tremors since 19:34 on the 23rd of July, as nothing has been recorded there. So bear with me folks, and when I get more info as to whether there have been any tremors in Australia for the last 5 days confused .....I'll jot them here. wink Duck.

I have been watching some cloud formations across New South Wales today and there has been a huge spread of 'ribbing' from the far west of the state, right across to the coast (encompassing the regions around and below Sydney). Now this may mean nothing on the tremor front and may just be a weather phenomenon, but I do feel there may have been/is some fault line (maybe just minor) jitters, here and there, right across the lower half of the state.
Victoria has had a faint 'energy' running through it in the last couple of hours too. There have also been some awesome 'ribbed' clouds to the east of here too this arvo.
I hope Geoscience updates their registers (tremors) tomorrow. I've got a gut feeling that many states (not including Qld. maybe) have had some jitters in the last 5 days....

Re: Earthquakes - 29/07/2013 19:39

Hi Petros wink
That's interesting. All I know (with my limited knowledge) is that they put a seismo in the Narracan region near a fault line which was showing activity some years (?) ago, to monitor it's behaviours. Unless it is a super dooper sensitive instrument, I am very curious about this seismo's rather regular moderate spikes recently.
I personally think (if this hasn't already been done) a couple of other seismo's could be dotted along the north to south regions, say from the Lilydale general region, dotted down towards the south. This would be east of the Dandenong Ranges. That's just my amateur thought/opinion....I wish I could have a proper registering seismo at my place, but I think I may be too close to a main road for it to be accurate at certain times of the day.

Anyways, Geoscience is starting to put up some readings for tremors around Oz for the period of the last 6 days. The NT had an M3+ today and, so far, only one other tremor in WA has been put up on their site. I'd be gobsmacked if there actually hadn't been any other tremors in the last 6 days...will see if Geoscience put up some more recent ones soon.

The western side of the ROF has been quite active in the last couple of days (including the NE of the Indian Ocean/NW + N of Oz mainland - Indonesia and near India).

The central/southern states of the U.S. are still popping up with M3's and there may be more to come.
Yellowstone seems to be feeling the affects, sometimes, of semi-distant tremors. I get this feeling that Yellowstone has 'energy' passing through it from other regions and only occasionally is getting a little upset on a local basis. Though, I do get a sneaking feeling that this region may come up with an M3(+?) in the near future.

The Mediterranean is still experiencing quite a few smaller tremors with the odd M4 or M4+ popping up near Crete/Western Turkey and potential other spots.

Japan is experiencing quite a few tremors daily, though these don't all show up on the Global Incidents Map.

New Zealand's tremors are occurring, as I said in another post, generally along the associated fault lines of the Cook Strait quakes. I feel this region may feel another moderate tremor again soon. Near Christchurch (west'ish) had a decent rattle and I hope this doesn't set off the faults nearer to Christchurch region.

Hawaii, I feel, may experience an M3(+?) at some point soon, as may the west coast of California.
The region near the Queen Charlotte Islands experienced a moderate quake recently, like I felt it would. I don't think the potential for another movement has ceased there.

Alaska has been rattling with quite a few smaller tremors lately and I feel there may be a moderate one on the horizon soon, maybe in the north of the Gulf and/or along the Aleutians.

Woops, I have rattled on blush

I'm getting a sneaking feeling that we may see an M6+(?) occur very soon either from Japan down through to Indonesia somewhere or to the east of Oz (well away from our mainland - well overseas perhaps). 'Water' or just offshore somewhere is sticking with me.
I suspected the Banda Sea region may experience a movement post the Ceram Sea (Indonesia) movement and it has. I've been out and haven't had a chance to jot much today.
SE China, SE Greece and SE Italy are resonating with me for some movements, but again folks, these are just feelings, not predictions, I could be very wrong.
The south of Jakarta (off southern coast), south of Padang and the Sulu/Celebes Seas may experience some movement.

For now, Duck.

extra; eastern Kasmir, east of Islamabad, has just come up with an M5.4. Very recently I mentioned the possibility of movements like this along this curve of these mountain ranges. In my mind it may be because of northward pressure from south of these ranges (Himalayas) - just a thought.

Just observing a glass of water on a table atm. It is showing some faint movement. Instead of just a slight vibration (when energy travels through from a distant tremor/quake) there is a very slight wobble in the water. This usually has me suspecting that this is localized to Vic and it may be one of our faults moving/jiggling slightly?? Building to a tremor?? not sure, but it is reminiscent of movements past.....time will tell...

Re: Earthquakes - 04/08/2013 14:34

Sometimes I find it a little creepy that I jot info or notes on a particular region (mainly because it may be on my mind or twigging my intuition for that moment) and the region/s mentioned may come up with a substantial movement.
Japan has just experiences a near M6 in the last hour or so. And, my last post was about an article on Japan - see previous post.
My general feeling is that if we start to see some M5+ movements regularly along the western edge of the ROF (within a period of approx a week or so), meaning if we may see M5+'s start to pop up from Kamchatka, all the way down through to even NZ (and maybe over to Easter Island and Chile {and maybe the Gulf of California - near la Paz}), there may be an outside chance that a substantial EQ may be on the horizon in a 'vulnerable zone'. This just a lay persons' hypothesis and is not based on scientific knowledge.

I hope this latest quake in Japan hasn't caused damage or concerns for the peoples there.
This latest M5.8 is in the general region impacted by their 11/3/12 M9 quake.

Re: Earthquakes - 05/08/2013 11:50

This video is not related to EQ's, so sorry to put it here, but I found it fascinating (and a bit creepy [that word again]).
It is a longish video (about 14 minutes) about a time lapse of all the nuclear explosions between 1945 and 1998. It is an artistic impression, by Japanese artist Isao Hashimoto with sound and animation, which is amazing and quite numbing to watch.


And, while mentioning Japan in a previous post, have a look at this vid, which gives a timeline in 2011 around their terrible quakes. Not meaning to be morbid here, but the 2011 quakes put into this perspective is also a reminder of what the folks of Japan had to contend with then. Let's hope we don't see this activity again.

Re: Earthquakes - 05/08/2013 17:24

Hi Jax.
I have, on occasions, wondered what 'life' the fallout has post an explosion. Meaning, how long does the radiation last for before it can be deemed 'safe'.

Just regarding EQ's today, some regions in/near Chile, Indonesia so far, have come up with some reasonably sized quakes, as I felt they may. The islands maybe, offshore e.g. PNG across to Samoa/Tonga may feel some movements too this week (if not in the next 24-36 hours). Taiwan and near Davao maybe too.

Before the Owen Fracure Zone region M4.8, SE of Yemen, off shore, a buoy NE of this location was showing some jittery readings.

California has had a cluster and an M4+ and this region seems to be a little jittery still, even though regular small tremors are not unusual here. For some reason, as I mentioned in blog (June/July?), I felt there may be a 'water/sea issue' for San Francisco region or somewhere along Cali west coast where there is a large bridge (i.e. water passing pylons in a strong current)....just a feeling.

For now, Duck.

Some 18 days a go, I mentioned how surprised and pleased I was for WZ that the view count for this thread had reached 100,000. Since then we have amassed an extra 14,600 views, fantastic.

Anyway, Samoa has experienced the M5+ I said it might within a possible 24-36 hours from the time of the last post. Chile regions also had a run of M4+'s too.

The Californian coast is seeming to show intermittent bursts of M3's and an odd M4. The energy here seems to come in such bursts and to me, feels like a little more agitation along the fault lines there, and feeding back in or from the mountain ranges to the west of Yellowstone and surrounds. Yellowstone also came up with the M3 I was expecting and I still feel there may be another on the horizon. This 'energy' may also be translating to the Canada/Washington border.

Alaska has been experiencing rather a run on tremors too. This may be a sign of another moderate (M4 [+?]) movement in the very near future.

One thing I noticed after Japan's, M6 the other day, was that the Mediterranean region followed on almost immediately with multiple tremors. This may not be related though....?
I am getting a feeling that there may be an M4+ for the Mediterranean region brewing - either Crete or maybe Turkey.

The Himalayan region is still experiencing the odd M5...and may continue to do so sporadically.

Australia -
The gold medal for number of tremors in Oz goes to WA.
Silver goes to NSW.
Bronze goes to SA (which, along with WA is usually top of the list)
'Runners up' have been the NT and Tassie/near.
Victoria has been disqualified from this list for being very uninteresting so far. confused
Here's Geoscience records for the last 30 days

For the moment, Duck.

I didn't think I was imagining things...Tasmania came up with an M3 near midnight, 3/8/13, which didn't show up on the "Australia - last 7 days map"...
It was just offshore on the SSW of the state where various 'deviations' in the plates all point to this spot. Link to Geoscience record here...

Shakey night in Vanuatu with a M5.9 followed closely by a M5.7. Both earthquakes were quiet with no loud bangs or jet noises like the ones before.The roosters started crowing in the dark for over an hour and the hens joined in, making a hell of a racket! Not much sleep.

Re: Earthquakes - 07/08/2013 09:00

Hi cyclone sally.
The islands can be an interesting place to be. I remember when I was in Fiji, many moons ago, I was watching some beautiful coral sea snakes on the waters' edge, when a fairly regular tremor (at sea) for the region occurred. The snakes (like in suspended animation) stopped still for a moment, then got on with wriggling around quite happily. I remember thinking, I felt happier when they got on with playing in the little waves. That may sound silly, but animals are such a good indicator of what's happening in the environment.
Just like the chooks/roosters you mentioned, they are terrific sensors of changes and happenings around us.

No matter what though, feeling the ground move is quite unnerving. These EQ's in Vanuatu were quite close to the islands, but didn't raise any alert for a tsunami. There may have been a little water disturbance, but the mechanisms of these movements were not apparently the type to cause concerning water disturbances.

I hope there weren't any structural or other issues for you and the islanders.
I know you are coming back to Oz at some point, and though there are the odd tremors/EQ's occurring, I'm sure you'll miss Vanuatu in many ways - the people, the climate, the sea and the food. Great place - you lucky thing smile

Cheers,
from the Duck.

Re: Earthquakes - 08/08/2013 10:21

A couple of days ago, I mentioned that I felt since Japan's M6, that the western side of the ROF (Indonesia, Aleutians, the Pacific Islands generally etc.) and Chile, Easter island...may come up with movements in concert with the NW movement (Japan). Unfortunately they did, but thankfully not too problematic for the regions, as far as I know at this stage.
Central America was another region I thought may be affected, but didn't mention it here.

Greece and Turkey also came up with some moderate movements, though I thought the SE of Greece may show some reasonable movement, but it was more west of this location. In the last few minutes, Crete has experienced an M3.1.

There may be some more moderate EQ's towards the Himalayas region, Northern India, Myanmar etc...

I still have a feeling that we may see an M5+ in the Pacific region, maybe north or north east of the Australian mainland (another country) and/or approx 800 kms west of Nikolski, Alaska, which had an M4.2 (8/8/13 US time) - co-ord's 50.205N:179.96E. Now that last possible location is just a feeling - for some reason I am being drawn to this region (and I may be quite wrong here).

The fault line running through the San Jacinto Mountains in Southern California, from approx east of L.A. and to just west and NW of the Salton Sea has been experiencing several smaller tremors. This fault line splinters off in a SE fashion from the San Andreas Fault (I call the San Andreas, in relation to these smaller faults - the Parent Fault in this region [California]). There may be a moderate tremor for this region, anywhere from L.A. down to near Mexicali...will see.

For the moment, Duck.

Just as I suspected for NSW, an M3.3 has just occurred.
It happened about 50-100 kms SE of where I said it would, in the Maitland, Hunter region.
Here's the Geoscience record of it.

Taiwan has also experienced an M4, like I felt it would too.

It was a strange'ish feeling. It was as if an elephant had hit it's head underneath the house. Ok, that sounded a bit silly smile. But it wasn't like a quake/tremor with build up and a tapering rumble. It reminded me of the suddenness of Lilydale's EQ recently.....without explosive sound.

No buoys are currently in event mode.
The Pacific Ocean north quake is an undersea quake, seeming to be located near 'trenches' and a semi-circular (of sorts) undersea mass - old volcano??? Maybe not, but looks a little like an old half rim of a volcano??

For the moment, Duck.
Posted by: duckweather

Re: Earthquakes - 13/08/2013 09:57

At the time I posted that info on the north Pacific Ocean M6+, I was a little suspicious that it may have been a glitch, because the USGS, Geoscience and some other agencies didn't immediately register any movements there. So, this quake can be disregarded.

The Atlantic, west of Spain/Portugal is a region I have quietly been watching for the potential of M5's/M5+'s. One has come up in the middle of the Atlantic (Mid-Atlantic Ridge) today, as have a few other smaller EQ's west of Spain/Portugal (and very close to this region) in the near past, as I felt it may.

Another region which is moving like I felt it may, is the central, lower group of the U.S. states - Oklahoma, Tennessee, Arkansas etc..
There is a feeling that not only fault lines may be unsettled there, but that there is a possibility that the Gulf of Mexico waters are infiltrating an undermining the lands in Louisiana (sinkhole related issues). A combination of these two things (faults and water), I am guessing, may not be a good thing....?

Here's an obscure thought (nothing new for this daffy Duck...), could some of the sinkholes/land drops be because of old and new fault line activity???? I am getting a feeling that some of these occurrences may be the land giving way in splinter (off the parent fault) faults activity - some maybe previously unknown/mapped minor fault lines.....??

Anyway, the Solomon's have experienced an M5 today and I feel that some of the other islands in the region may follow suit with some movements too.
I also get a wee feeling that Japan (and region) may experience another run of moderate tremors in the short term. There may even be a considerable movement there (hope not).

Hawaii experienced the M3+ (actual M4+) yesterday. Felt that one was brewing.

For now, Duck.

Also meant to mention too, on the local front, that I have observed some ribbed clouds forming and disappearing in the NE and eastern regions of Vic this morning.

Re: Earthquakes - 13/08/2013 16:19

6.3 up in the Banda Sea yesterday was clearly felt in Darwin. A little bit more prolonged than most of the recent shakes up here too.
Posted by: duckweather

Re: Earthquakes - 13/08/2013 19:38

Hi Orebound.
With all the activity (EQ) in the regions above the NT (and Oz in general) that occurs on a fairly regular basis, I reckon that where you are, is one of those regions where the effects of EQ activity is the most felt in all of Oz. Though the movements are usually not on Australian land there, except for the odd one, it must still be a strange feeling to feel the earth move as a result of another country's tremors.
The region where this quake emanated from, predominantly experiences quakes at a reasonable depth from about 70kms down to the deepest depths (many hundreds of kms). A lesser percentage of their quakes are nearer the land surface - from my memory of their EQ history.
I am only guessing that if the larger quakes there were any shallower than the one recorded recently (M6 at 92kms deep), the impact of such a movement may have been more serious.
Most of the quakes in this region occur on and/or north and NE and east of the land of East Timor (including the Banda Sea). The tectonic plates there are, I believe, a more complex group, than the general Australian Plate near this region. I may be wrong here, but that's how my memory serves me for the moment smile
(I've gabbled on again blush )

Anyways, the more prolonged movement you felt may have been because of 'gradual' behaviors or a movement of an extended time vs a sudden jolt. To be recorded as a '6' though, it must have been a good old movement - better 'down stairs' than on the 'first floor' (near surface) I suppose.

For now, Duck...

I wouldn't worry about "gabbling" on, I find your postings very interesting reading. Intrigued at how your "gut feeling" seems to be able to predict quakes fairly well.

Last tremor I felt was back in September 2011, in SE Germany. Thought it was thunder at first (thunderstorms had been forecast) until the bed began to move, then I realised what it was. The lady at the front desk confirmed it next morning.

Hi Werner.
Thanks for your kind words. I was a 'nature child' as a kid and was quite attuned to changes in nature - probably more so than these days due to having a pretty busy life (family, work etc.).
I wish I could focus on this particular interest of mine 'full time', making my posts more thorough and probably more accurate too. I do miss some things, but that is because of my daily distractions and that I am certainly not always right with some of my observations.

I think near Mt. Rat in South Australia has just had a tremor - M3 or m2...

Oh hang on, I just checked this too and this may be associated with this movement (visible for the next 45 mins from now) this set of seismo readings

and...there was an M5 in the Philippines 45 minutes ago, but at 80'ish kms deep I wouldn't have thought that it may 'upset' our southern Oz seimo's as much as the link to seismo's above...

Re: Earthquakes - 15/08/2013 10:03

The Norwegian Sea has come up with an M4.5 (25kms deep) in the last hour.
Now, not only has this region been one I have been quietly observing for the last 12 months and feeling that the volcanic vents there may become an issue since being noted and written about by scientists in 2008 (though I had a strong feeling that that volcanic activity was present and would become active there, well before the 2008 discussions), I have noticed there have been several articles being written on this location in recent times, maybe for it to be potentially recognized as a nationally protected (status) region.

Here's a blog post which is succinct and nicely put together about just this topic - the volcanic vents.

Re: Earthquakes - 15/08/2013 19:39

Now there's a coincidence...2 minutes after my last post, an M2.4 occurred NE of Bonnie Rock in WA.
I still feel though that we had a faint movement here at that time too, but nothing has come up on Geoscience as yet or may not at all.

Cook Strait in NZ has moved again with an M5, with probably intermittent movements to continue there.

California is still jittering with a range of tremors and may feel another M3+ this week. I'm wondering if this may occur near Los Angeles or San Francisco regions...?

Maybe near Samoa and Fiji could also experience some moderate movements too.

Obscure note for tonight...
About 500kms east of Newman in WA, I am wondering if there is some sort of fault activity/jitter there for a period of time today.
At this point (halfway between Newman and the NT/SA border) imagine an elipse shape of about 350kms wide (east to west).
This location is well ESE of the M2.8 on the 13th of August near the Pilbara, WA.

Cough, cough, clearing a furball and to carry on with EQ watch...
Bali Sea just came up with an M5 (deep at 298kms) and was followed on by Kepulauan Talaud, Indonesia with an M4.4.
We may see Japan experience a moderate tremor next (or maybe Taiwan), then maybe PNG and/or near Kamchatka/west Aleutians.
Sometimes a corresponding tremor can occur down Central/South America. When NZ experiences such large EQ's like the one/s seen today, you can expect 'neighboring' and/or an opposing region to 'react' too.
This is just a feeling, as I always say, not a scientific opinion or prediction....

Re: Earthquakes - 17/08/2013 10:45

Here's an article on The Watchers site, which gives a succinct account of EQ stats, videos of the NZ EQ dynamics and other info regarding the Cook Strait series of EQ's.
"Severe, damaging and shallow earthquake...ocks" by Adonai

As I mentioned in my previous post, there may be subsequent moderate EQ's post the NZ quakes. Vanuatu and Tonga were two regions which I left out as potentials for M5's - which were rather obvious locations for potential follow on EQ's after NZ's movements. I usually add those in the 'list' but forgot to yesterday - (roll eyes).

A couple of posts ago, I mentioned that a buoy was in event mode in the Bay of Bengal (near India). I found a notation of an M4.7 which had occurred in ESE of Port Blair, India - USGS
This may have been the trigger for the buoy, but I'm not 100% sure atm..

I am getting a wee feeling that there may be an offshore movement between the west coast of southern Canada and down to west of Eureka, California soon. This feeling seems to 'marry', in my mind, with the potential of movements yet to occur in the Pacific....?

For the moment, Duck.

Re: Earthquakes - 17/08/2013 14:20

NW and west of Renmark in South Australia may be showing some fault jitters.
Now, I know when I mention these regions (re: jitters), they may not always come up with a tremor in the short term or one that is notable enough to be recorded by Geoscience formally; alternatively I may be wrong too, but when I feel I observe potential 'jitters', I feel there may be a possibility of a movement in the future - (from 0 to approx 55 days [according to a Japanese scientist]) from noting my feelings.
Sometimes tremors have occurred in the day/s I have noted certain regions and weeks for others...some not at all. So take what I say as just thoughts only, not predictions (sound like a broken record, don't I? smile )

I think near Roma in Queensland may be showing some faint jitters too.....

Re: Earthquakes - 17/08/2013 17:46

That buoy in the Bay of Bengal is very interesting. Have a look at the current 'stats' for it - here.
It seems that since the first quake at 0522hrs (US time), the buoy reading depth has not regained the loss of depth reading. It has gone on from 3792'ish metres and stabilized at about 3768 depth reading, post the second quake (just on the other side of the plate edge) M5.2 - WSW of Banda Aceh.

Question - Has the sea floor risen, indicating (maybe) the potential of another serious movement there, let alone a sea floor change.....?
Posted by: duckweather

Re: Earthquakes - 19/08/2013 11:55

Hi folks.
The western side of the Pacific plate (intermingled with other smaller plates etc.) has been misbehaving as I thought it would, following on from NZ's recent M7. From NZ, up through the Pacific islands, across to Indonesia, up through the Philippines, Taiwan and Japan. The western end of the Aleutians came up with a moderate quake too, as I felt it may. But, the Kamchatka region hasn't so far.

The quakes in northern India, Gengqing/China and Afghanistan are all 'near' the Himalayas. This is another region (long spread) which I felt was going to show 'spot' quakes recently/currently. The 'energy' here (and regarding the movements near Banda Aceh and the NE of the Bay of Bengal) I feel is emanating from the Indian Ocean central, north and east.

One region my mind is sorta 'stuck' on is the west coast of California, and up through Washington and into the Canadian west coast (near the Queen Charlotte Islands). Not saying anything catastrophic will happen there, but maybe an M4+ may come up in the near future. Equally, the U.S. inland may feel an M3+ (+?) in the general regions of western Nevada, Baja and maybe in the 'T' shape region of Oklahoma/Arkansas/Tennessee/down to Louisiana. But I could be wrong.....just feelings.

For the moment, Duck.

Re: Earthquakes - 20/08/2013 11:05

Another great article by Adonai (The Watchers) explains how experts in NZ are concerned for another large quake in the Cook Strait. This article coincides with the feelings which have been niggling at me regarding this region and the folks who are dealing with living with the threat and the recent/current fault movements there.
"Deep sea oil drilling raises concern as...s, New Zealand"

Geoscience has started putting up tremors registered in Oz in the last 5 days. I was wondering why nothing had been registered recently, as I was sure there have been movements in WA and maybe SA and NSW...(not just reverberations from quakes overseas/neighboring countries)...will see if any other tremors are added to the Geo site soon.

Re: Earthquakes - 21/08/2013 10:11

The M4.7 - 129km SSE of Chipinge, Zimbabwe - (Mozambique on the Global Incident Map) is very close to the M7 they experienced on Feb 23 2006.
This region is not immune to EQ's of a moderate to larger size, as the notable EQ's of this region describes.

Quote:
Relative Plate Motion

The magnitude 7.0 Mozambique of February 22, 2006 occurred along the boundary between the Africa and Somalia plates. The relative motion perpendicular and parallel to the Africa and Somalia tectonic plate margin is a combination of convergent, divergent and transverse relative motions. Divergent and convergent relative plate motions would be expected where plate motion is normal to the plate margin. Transcurrent or transform faulting would be expected where relative motion is parallel to the plate margin.
USGS

Africa is one continent which I have eluded to in the past (blog) as being one which may experience some moderate/maybe larger quakes in 2013.
Tanzania and the DR Congo, the Gulf of Guinea, SW of Liberia (at sea), the region between Eritrea and Somalia, and the north coast of Africa (Egypt, Tunisia/Algeria, north of Morocco) are places I have felt for some time may be prone to moderate movements. The sea space between Portugal and Morocco is another region I am sometimes drawn to for potential moderate movements. (All just feelings folks).

The vast spread from west to east of the Mediterranean is experiencing regular smaller EQ's/tremors, with the odd moderate movement. I generally feel that from the central locations out to the eastern regions of the Mediterranean Sea may be more vulnerable to some moderate movements.
Some general regions which I am almost constantly drawn to are Turkey, Crete, Italy, SE of Yemen, Karachi (Pakistan), Islamabad....just to mention a few. (This may have no significance regarding EQ's).

The northern Mid-Atlantic ridge just came up with an M4.9 (fairly shallow depth).
Now, when you see EQ's come up in the Atlantic, keep in mind this report - "Atlantic Ocean Floor Unexpectedly Pumping Iron" Aug 20, 2013 11:39 AM ET // by Tim Wall The location for this happening is south east of the M4.9.

The extent of this iron expulsion is unknown by the scientists - the size and area coverage.
There have been reports too, one, if I can find it again, discusses massive whirlpools which form near there (this may be a weather/warm*cold current event)
This general area of the Atlantic has quite a few fascinating naturally occurring events.

I had to think about whether to put this next gabbling on here – as I had a vision of some of you thinking “whatever” or “Duck really is daffy” or “that’s it..Duck is deranged”, but…what the heck, I shall cover one eye, whilst peking out from the other (as Duck’s do) and jot this note.
Though, the end of the following jumble of thoughts alludes to particular general regions of two countries. So, on a serious note, the following is not a prediction or an intended warning for a large EQ for these regions. The following is a curious account only of a sequence of events/numbers which occurred and tumbled through my mind yesterday. .

While driving to my son’s school to pick him up yesterday (23rd of Aug. 2013)…at 2:37 pm, the car camera screen display began scrolling with red numbers – 141 and 23 ( these numbers were actually 141 and 53 – petrol price display nearby in the camera’s line of sight)
After being out, driving for 1 hour and 23 minutes, I sat down with a coffee and the laptop to look up these numbers – 141 and 23/35 – on the net,
141 is in the sequence list for centred pentagonal numbers.
In this list of numbers, the closest previous 'date' to 2013 is 1891.
The first record of an EQ which came up in a new search for ‘1891 earthquake’ on Google was the great quake of Mino-owari ,Japan on 27th October, 1891, at 21:37. http://earthquakes.findthedata.org/l/2264/Japan-Mino-owari
Out of curiosity, I looked up the coordinates of 141 and 23 (bottom blue marker) and 141 and 35 [reverse of 53] (top blue marker) found these locations on a map below. Ignore the red marker.

The coordinates of 141,53 is near 300 kms north of Sapporo, Japan: Russia/east of Russia: west of Sea of Okhotsk.
As I alluded to folks, this may just be an unfortunate ‘play’ on numbers and an example of how the mind can wander for a misguided 5 minutes.

Re: Earthquakes - 24/08/2013 12:11

Just a short note;
The west coast of California (near LA particularly) and Washington (amongst other locations) have experienced the quakes I felt were brewing unfortunately.
The video of the seismograph reading of the off shore Central California (near LA) can be viewed here; Shaking caught on abc7 (US) newsroom camera - seismo

The tremors/quakes in California/Nevada occurred in fairly quick succession - seemingly generalized movement with moderately shallow depths.

Re: Earthquakes - 24/08/2013 17:10

Fiji's 2 EQ's today have been very deep. I am guessing that 'follow on' tremors may occur in the surrounding regions - some also deep and some closer to the surface.
The movement gravitated south from the first quake and the magnitude was slightly greater.
This/some movement may translate further south again - ? and maybe west over to New Caledonia, Vanuatu, Solomons, PNG...?

For the moment, Duck

Re: Earthquakes - 25/08/2013 18:20

For this post folks, I am going to do something a little different to what I normally post on day-to-day ideas/feelings on where EQ’s may occur and post event information.

As I have said in my blog and here on WZ, since I was a child I was ‘tuned in’ somewhat to changes in the environment, whether I was on land or sailing on the sea in our homebuilt sailing boat – the Albatross. Cloud formations, environmental changes, animal behaviour and so on, nearly always seem to captivate my imagination.

Many of you have read in my posts or ramblings about cloud formations, ribbing and deviations, which may be precursors to potential tremors. Some of these formations are very subtle and some are profoundly obvious and expansive. Many a time I ‘read’ satellite pictures to gage potential near-locations of possible/maybe movements. This is combined with unexplainable feelings of being drawn to certain locations I get on occasions. On a local level, the odd cloud formations, post an earth tremor/quake can indicate the location of a jittering fault line, or a release point of stress generated moisture , producing a vertical, sometimes jaggered cloud. I have observed these formations after the Lilydale, for example, short-sharp tremor this year. Three of them appeared along a north to south axis, and lasted for a range of time being several extended minutes to up to 30 minutes. Some Japanese and Chinese observers/scientists have also observed these vertical clouds post some earthquakes in their local regions. (I have mentioned this in a previous posts/s).

You may have also read about me rattling on about the stillness and silence, even if momentary, of the ‘air’, with an absence of bird sound, strange animal behaviour and an eerie feeling of impending possible ground movement or other change.

A friend asked me how I concluded as a kid, through my ‘observations’ of cloud formations, for instance, a potential earth movement may occur. Well below is what I wrote as a child about my then basic thoughts.
* There are regular gaps, lines, in the clouds.
* The earth gives off electric/magnetic vibes up through the atmosphere.
* The clouds part and clear in the places these vibes travel through them.
* The earth is affected by solar activity.
* The animals sense this (e.g. electromagnetic) activity and faint ground shifts before humans.
* The air is still, usually, because of these (earth) momentary changes.
* The sea can also change its behaviour and appearance when the earth is giving off signals of (pending) change.
* Changes below, whether at sea or on land, some can’t be seen, but a keen observer and those sensitive to change can feel them.
* Positive ions and negative ions.
* It is like the earth is sending up vibes like a heat haze to part the clouds, from cracks in the earth.

I wrote the above notes in a diary I occasionally tended to when I was 8 years old. This diary was lost in a house move (unless I find it in the roof of my house in that big box shrouded in cobwebs, next to the possum ‘bed’ – which I ain’t venturing into to investigate eek ) But I remember word for word some of what I wrote back then.

As an older adult (ol’ Duck), I still believe in what I noted as an 8 year old, but these days there are more scientifically correct words to describe these elements.

I wish I had studied science at uni (I tossed up between graphic design, psychology and the sciences), then not only would I have followed another innate passion of mine and had all the right words to describe my observations for myself and the good folks here on WZ. But I try with the limited time I have. Sometimes I find some great info, which speaks with greater clarity on the geo-sciences than I can, such as the article mentioned below.

I found a great article by the USGS, which applies these better scientific expressions and words regarding some of what I felt happens here and there with the earth as a kid and much more. Just briefly, much of this article discusses electromagnetic, moisture, physical behaviour, electrical output/activations (charge dispersions), effects of interacting physical properties of rock/surrounding elements and so on, and potential precursor signals (and during and after effects) of earthquake activity and the equipment and studies to measure such.
It is an interesting read, and, if I may, I would like to consider in relation to and add the observations of this paper to my own general observation of some atmospheric moisture/cloud effects/geo-electric/magnetic and presentation, to assume and suggest that they are related to some degree. (This may be to the disdain of some scientists and not others).

Re: Earthquakes - 26/08/2013 08:12

Just a quick note-
In regards to a previous post of mine, which show the location of a couple of potential quakes near Japan's volcanic islands and the east coast of Honshu, Japan, after I gabbled on about some numbers which resonated with me...these quakes came up - one in the exact location of Honshu and the other just east of the other blue marker on my map example.
Now this was probably just a coincidence. The Honshu location is not an unexpected region for tremors/quakes.
California is still 'moving' with some tremors in the M3(+) range, which I felt it may and I think we may see some more to come unfortunately.
Anyway, gotta dash,
Duck.

Re: Earthquakes - 28/08/2013 13:55

Well blow me down...
I have been out all day till now and not able to jot the notes I wanted to.
I was wanting to mention the strong feelings I was getting, since last night, about the Pacific regions - near NZ (north of) and the regions and the north Pacific.
Also I was circling with a finger,on a mobile phone map this morning to my son, the region of the Atlantic which has just come up with an M5.
The Pacific region of the Kermadec's has come up with an M6.
The M6 (North Pacific) also listed on the Global Incident Map may be a dubious location at the moment, it needs further verification.

We may see more moderate quakes (M5 or M5+) in the Pacific - maybe around the Pacific west island regions, e.g. near Fiji, Solomons, Vanuatu, PNG and maybe along and up to Japan.

The west coast of the U.S. will continue to experience smaller tremors and a bit of an intermittent experience of potential M3+'s and maybe an M3++(?). Baja, California, has experienced the M3'ish I felt it would and this maybe a region which may experience another tremor...
There are some other regions I will note too when I get a chance...

For the moment, as I've gotta dash again...

Re: Earthquakes - 29/08/2013 10:11

Finally folks, I can grab a bit of time to post some info on quakes.
Below is an image of our continent and some neighbours, regarding the earthquakes/tremors in the last 30 days (August mostly). Uploaded with Imageshack.us and the image courtesy of Geoscience.
Sometimes it is good to see an image rather than just words/stats.



On the local front, I felt another, but very small, jolt yesterday. Strangely enough though, it corresponded (time wise) with NSW's tremor...

I'll add another post later.

For now, Duck.
Posted by: duckweather

Re: Earthquakes - 29/08/2013 17:47

I keep getting an irking feeling that Vic or SA (also slightly drawn to Qld) may experience an M3 (maybe M3+). The 'air' here has been quiet in some moments (no bird sound and still air) and, unless my senses are playing up with that annoying damaged ear drum of mine, it feels like there is an energy in the air and a faintly audible rumble occasionally and ever so faint ground vibration (this may just be weather/atmosphere related - given some mild looking instability atm)... Or...I have had too many coffees on this gorgeous warm day smile and need retreat to a pond to paddle aimlessly in circles crazy .

I also get a feeling that there may be a sizable EQ brewing somewhere (dry/arid region and/or coastline), which will be maybe, and unfortunately, newsworthy.
Remember - these are just feelings and I may be very wrong...

For the moment, daffy Duck.

Re: Earthquakes - 29/08/2013 20:49

Just to follow on from my last post, there has been a report on Earthquake Report.com website of an as yet unlisted M2.9 in Melbourne, around 8pm this evening...will see if I can verify this.
Posted by: duckweather

Re: Earthquakes - 29/08/2013 21:09

Ran out of time to edit above post, but it looks like a short, sharp spike was registered on a seimograph NE of Melbourne and a small 'grumble' after that. But I will wait for Geoscience to formally register any movement on their site.
I too thought I felt something but am not sure if it was a wind gust, as I was moving my car at that time (playing musical chairs [cars] with the youngin's rearranging the parking places in my driveway).

Re: Earthquakes - 30/08/2013 21:25

Along the west coastal and inland regions of the U.S (California and Washington/Oregon), the tremors they are experiencing are generally the west coastal regions, and east into some of the inland regions – considered to be in hazard zones for tremors and fault activity. A few tremors have ‘ventured’ into some regions, for example near Spokane, which are considered by the USGS as lesser expected hazard zones. According to the USGS fault line mapping, most of the tremors have been near/along fault lines and a few aren’t.
It appears to me that there has been an uptick in tremors in these hazard-zone regions, which, if you look at the USGS mapping, the tremors seem to be occurring generally around the greater west and SW edges of/near the state of Wyoming (which mostly ‘houses’ Yellowstone National Park).

Offshore, west of Eureka, northern California is a region which I feel may be vulnerable to a moderate tremor/quake. As maybe offshore of SW Canada.
I get a feeling that an ‘unusual’ location for a tremor/EQ may come up very soon (days).
Other regions I may keep one eye on are Italy, eastern and south central states of the U.S., Seddon (NZ, near Cook Strait), Chile (central coast), Santa Cruz Islands (and surrounding regions), Afghanistan (Middle East) and Sumatra. There will be other regions/locations which may come up with tremors/quakes which I will try and jot here later - too many distractions atm.

By the way nothing has come up on Geoscience at this stage for a Melbourne M2.9 yesterday. But I feel that NSW and SA may have had tremors today. Vic showed a strange spike at one point, but Geoscience hasn’t noted anything yet.

Similar to the U.S., the locations of the Alaskan tremors surround the general region of Anchorage, also what the USGS considers to be hazard zones – to the north, west, SW and a couple east.
If you want to look up the hazard zones and their considered degree – go here http://earthquake.usgs.gov/earthquakes/map/ and click on the ‘cog-shaped’ symbol to bring up options to change the appearance of the U.S. maps.

Re: Earthquakes - 31/08/2013 08:26

Hi folks.
This ol’ duck has been awake since the Alaskan M7 occurred. I didn’t know that this EQ had occurred at that time, but awoke (right ear drum ringing like a church bell) and felt the need to check the EQ maps… I wasn’t surprised to see a large quake had happened (my waking at the same time), as this has happened on many occasions in the past. So far, luckily, it appears the Alaskan quake has not been too problematic for the folks there.

See the Earthquake Report.com site here for;
Xizang-Nepal border region – EQ reports from folks there
Andreanof Islands, Aleutian Islands, Alaska – M7 (depth between 10 and 33 kms approx) – ongoing aftershocks
New Zealand tremors, Vanuatu EQ and so on….

The Himalayan, Alaskan, Japan, Pacific island’s, Indonesia and a few more, are some of the regions I have mentioned here and there in past recent posts as ones which I have felt may be ones to watch for potential movements – some maybe sizable. My suspicions were of a building energy and ‘shifts’ which may culminate in an active period of EQ’s, increased volcanic activity and ‘pulling/squeezing’ of some land surfaces/sea floor structure displacement/movements.

As I also mentioned in a previous posts, I had an irking feeling that there was going to possibly be a newsworthy, sizable EQ (maybe more to come) which may be near a coastline or in an arid/dry area. Though the Alaska (Aleutians) large quake has occurred, I still have a feeling that we may see more in the M5+(+?) region in the Pacific (coastline, islands, offshore in some locations). We may see the odd moderately sized quakes dotted around the world, including a few of the oceans.

The (lower) eastern states of the U.S. , on and around Tennessee , Alabama etc., have experienced tremors (actually 3 in close succession) , which I had a strong feeling would happen within the last 48 hours or so. This ‘section’ of the U.S. covers part of that “T” (right top part of ‘T’) shape I was talking about a couple of posts ago, as being possible locations for tremors and maybe a moderate EQ soon.

I’ll add more a little later,
Cheers, Duck.

Re: Earthquakes - 31/08/2013 11:26

Mallacoota in Victoria (Geoscience record here) has come up with an M2.7 at about 9am today. (Maybe my suspicions about potential movement in Vic [and the old musical ear drum] were 'good' this time)
There have been a couple of tremors come up in relation to the Tasman Sea in the last 24 hours or so. Movement has been recorded to the western side of NZ South Island and to the south of this island.
The far eastern end of the Himalayas (China) also came up with an M6 and an aftershock of M5.1 today.
The western end of the Aleutians (towards Russia/Kamchatka) may yet experience some movement too...
One EQ I find somewhat interesting is the M4.7 to the west of Honshu, Japan. The east of Honshu has been experiencing M5'ishes and this is translating to the west as well.

For the moment,
Duck.

Re: Earthquakes - 31/08/2013 19:10

Twin tremors for Vic today in the E/SE - north of Moe, about 10kms NNW of the Blue Rock Dam/Lake and the M2.7 near Mallacoota.
There is still a stillness in the air (around here anyway) and given that we have had 2 tremors today, I am getting a bit of a feeling that we may see another in the next 24 hours. It feels to me that there is still an unsettledness around Vic...could be wrong.
I also get a feeling that WA, SA and NSW may been in the same boat (regarding unsettledness) as Vic. Time will tell.

The Aleutian EQ's are continuing and fluctuating marginally in size, though still generally in the moderate to larger range of magnitudes. This, like the recent Cook Strait movements, are substantial and not 'settled' yet, as I felt it may.
The first of the ocean tremors I feel may happen today/tomorrow(Pacific) has come up, west of Central America.

Egypt has come up with an M4+ I suspected it might (mentioned this possibility a little while back).

As I usually say on my blog, peace and safety to all.

For now, Duck.

Re: Earthquakes - 01/09/2013 22:28

At this stage I am guessing it may have been a subduction quake...no info on Tsunami advice/mention yet. I am also guessing it may not have produced a worrying tsunami but may disturb waters to a smaller degree, but we'll have to wait for some formal information on such.
This was a decent sized quake and quite deep.
Let's hope it didn't cause problems for the islanders. Being so 'close' to the NT, it may have not caused damage to Oz, as such, but rattled a few things and maybe a sway (and/or rocking or jolt) feeling.

There maybe aftershocks Orebound...bib on...

This quake registered as a "shake map level 5" (USGS), which is a reasonable rumble for the folks on the islands nearby. Reports on any damage/problems for the communities will filter through soon...let's hope all's well there.

No tsunami warning/advice has been issued for Oz or other regions currently. The waters around the affected islands may have been a wee bit though...

Re: Earthquakes - 01/09/2013 23:10

Cheers for that Duck. Always enjoy reading your analysis of events.

Living on a second floor apartment we generally feel most shakes over M 5.5 in that region. Some stand out more than others. Obviously those in the still of night are those we take more notice of but this particular shake was noticed by several guests at a BBQ tonight for whatever reason. Most agreed with the M 6.5 or thereabouts analysis before Geo released the details so happy with that.

Keep up the good work.

Re: Earthquakes - 01/09/2013 23:23

Cheers to you too Orebound and thanks for the kind words.
Luckily (if you can call it that), I can get preliminary EQ notifications almost immediately after they occur. This is usually before some agencies place them on their maps. This can be handy for helping with 'early warning' of potential water issues (if I am sitting at my computer in the moment).
Cheers, Duck.

For the moment, here's the Volcano Discovery site lists of reports from Aussies and Indonesian folks on last night's big, deep quake.

I feel there may be more movements, maybe not as large as last night's (?), in the vast surrounding regions (left to Sumatra; across the top of Oz [overseas]; across to PNG and maybe up through Philippines, Davao etc.). Time will tell.

More later, Duck.

Finally got a small chance to jot some stuff here...
The image below (uploaded with Imageshack.us ) was from the USGS image of the Russian region which had an M6/5.4 today.
I zoomed in on this location as far as I could and a satellite image came up (below). I believe this was the sat pic for the region where the quake occurred (notice the star pinning the location of the quake). In the image there are the type of clouds (I gabble on about) I refer to as possible earthquake clouds.

Re: Earthquakes - 03/09/2013 12:06

Ok, just re-hashing some of my feelings regarding approx where some more moderate movements may come up,
The Indian and Pacific Oceans have experienced a couple of ocean quakes;
Afghanistan has had a near M5;
Texas an M4.1, Missouri and Arkansas smaller quakes each (in that "T" zone I've been rattling on about);
Canada, (Vancouver Island) an M4.1;
Kamchatka, Cook Strait (Seddon) and the Aleutians (location of recent M7....to name but a few, have also come up with quakes as I felt they would.

One region I was watching, but failed to mention here recently, is the British region. I had an irking feeling that Scotland/Ireland/England may experience an M2+ and they had an M3(?) in the Irish Sea. I felt that the 'energy' causing France and the Pyrenees tremors was gravitating towards the UK. Belgium/Germany/Holland may also have the chance of experiencing a smaller movement (just a feeling).
The Czech Republic and Poland may also experience some movement (M2+?).....

For the moment (and more later),
Duck.

Re: Earthquakes - 03/09/2013 15:48

Texas actually had two EQ's - an M4.1 and an M4.3. Here's an article which discusses such - " Two earthquakes rattle East Texas"

Two locations close to each other in location and size - near Perisher Valley (NSW) and near Corryong (Vic) - occurred yesterday (Melbourne time). I had a feeling that this part of Oz was still emitting an 'energy' and 'grumbling'. See Geoscience here

Just waiting for 'maybe' tremors to be recorded as having occurred too for SA and WA...will wait and see.

Re: Earthquakes - 04/09/2013 07:38

M6 SW Canada , with aftershocks.
On the 30th August (in a post) I mentioned that I felt (unfortunately) that SW offshore Canada may be an area which could experience a moderate EQ. The one that has occurred is a bit more than moderate, but apparently hasn't caused a tsunami (according to USGS). It was a very shallow EQ at 1km - 12kms deep (though the Canada Resources has one register at 212kms).
Will wait for more info to come out.
For the moment, Duck.
Posted by: duckweather

Re: Earthquakes - 04/09/2013 10:52

Boy are we seeing some considerable movements today.
Izu Islands, Japan M6.5 is near where I had that blue marker on a previous post's map. This one is a deep EQ at 404kms approx.
Queen Charlotte Islands is very unsettled though shallower in quake depth.
Mindanao, Philippines is also quite deep at 137kms.
Hawaii has responded with an M3.
Romania (as I also felt would) has come up with an M3.
Indonesia has been quite active too, just to name a few of the movements I was anticipating today (within last 24 and future 24 hours).
The activity in the Mediterranean has increased slightly in coincidence with the Pacific movements.
A couple more of the sea quakes I was suspecting may occur have happened too...

The deep quakes in the Pacific, generally speaking, seem to indicate some serious movement in the mantle. Because of this, we may see some more M5's (?) in the Pacific regions associated with the Pacific plate.

Japan's deep quake concerns me a little too, as I feel this may translate north to the Japan coast...but I may be wrong folks.

Canada, Queen Charlotte, will continue to rumble until it's movements have slowed and stabilized (I suppose that is pretty obvious). There is a buoy in event mode at this location. The readings have maintained curves relevant to the seas current wave/depth up and down curve, but the latest curve is accelerated in the time it has registered, in response to the quakes there.

More soon, Duck.

This is a rather active period with new corresponding shakes 4.7 Finland and just now a 4.2 Rat Islands, Alaska region

Great reporting in duck.
Posted by: duckweather

Re: Earthquakes - 04/09/2013 14:20

Cheers T.C.

With Alaska (Aleutians) revving up again with an M6.5, it has definitely been an active day. Buoys in this region (2 of them) are in event mode, but like Canada, no tsunami alerts or warnings have been suggested.

Not feeling any movement in Seattle is interesting. You would think with a quake that size and being not too deep, and being not far from the epicenter, that at least some vibration or jiggle could have been felt. Maybe the energy from this quake/s was very isolated and the inland regions were somewhat shielded by the land masses between the quake and Seattle for example. Still rather curious.

Holland has come up with the M3 (M3.2) I felt it would. France and Switzerland may still experience the odd M2 (maybe even an M3? for France) and maybe the Atlantic Ocean near Spain/Portugal, west of the British Isles and maybe SE of New Foundland (and maybe even further north than that) may experience movements too...will see...just feelings folks.

Central America (west coast) and maybe near Baja, California, may also experience movements...?

Hi AaronD.
Thanks for reporting on what you are feeling with the tremors/EQ's in Japan.
I, for one, will really appreciate what you can tell us of your experiences and observations of/from where you are.
There have been some sizable movements in the Pacific region today/yesterday and I'm sure many folks have been a little unnerved by these movements, though they appear to not have impacted anyone/place adversely, thank goodness.

Cook Strait seems to be reactivating again. Also areas along the west coast of North America are in for more movement/large shakes
Posted by: duckweather

Re: Earthquakes - 05/09/2013 19:43

Hi TC.
My feeling about the Cook Strait is that it will and has rumbled (nearby in/near Seddon) with smaller tremors and the odd moderate EQ. There may be a chance that it may experience a larger EQ at some point. Because this region is still rumbling, 'you' can't rule out the possibility of the larger movement.

You're right when you feel that the west coast regions of the U.S.(in spots) may be vulnerable to moderate EQ's, given the movements jittering along the coast (and inland), and the energies/movements around the Aleutians and Canada.
The east coast may also not be immune to some movements. For some reason I can't get Virginia and new York state out of my line of sight, as well as that "T" zone of the central/southern states. But this only means that I am getting a slight feeling about Virginia...so it may mean nothing.

The M6 in the Atlantic is just a touch south of where I felt a reasonable EQ may occur. Maybe the SW and/or SE of Liberia (and maybe in the Gulf of Guinea) may follow on at some point with movements (off shore)...maybe not. And maybe west of the Azores Islands.

The South Sandwich Islands region may experience some movement.

More later..my computer is starting to play up atm. Hope this post loads...Duck.

Re: Earthquakes - 06/09/2013 11:33

Hi perrywinkle.
Just looked at a seimo not too far from you and a movement was registered about 40-50 minutes ago (or there abouts)...need to verify that further. It wouldn't surprise me if you felt a tremor, NSW has been quite active along the SE and Sydney (very general region - inland) down to the Vic border.
If it was a tremor, my guess it was between M2 and M3.
You are also near a major highway and hopefully nothing has happened there.
For the moment, Duck.

Re: Earthquakes - 06/09/2013 21:53

For the moment, I can't find any info on the tremor perrywinkle felt...but that's not to say it didn't happen. Will see if Geoscience enters a register on their site.

If you WZ's want a bit of a brain-teaser, have a look at the following links I stumbled across tonight.
One is a blog post on poleshift.ning.com and the next link is (which is referred to in the previous link) ANF (Array Network Facility) (University of San Diego, California) . ANF does stipulate that after they review registers of quakes and are subject to change after analyst review.
On reading the blog post (on poleshift.ning.com), I found I was trying to nut out the time differences in the quakes he discusses. The Hudson Bay quake was seemingly the last quake to be recorded, and the quakes to the west had earlier times registered...I am wondering if this was because of a time difference between the regions??

Curiously, an M5'ish has registered in the Canada region at "08:43:54 September 6th, 2013 UTC" with no other quake corresponding with this on other maps, the ANF map etc...

I get a feeling that (and I may be wrong) the quakes removed from formal records may be because the main quake was registered, along with registrations in 'neighboring' regions. Now...maybe the other 'registers' were dropped because the epicenter was isolated to one region only. As I said, I may be wrong in my suggestion here and maybe the blog poster knows alot more than this ol' Duck.
I thought this was very interesting, all the same.

A few of these 'rogue' quakes have popped up on the Global Incident Map in the last few months, then have been removed. The last one I remember (?) was the M6 in the north of the Pacific Ocean.....

For the moment, Duck.

Re: Earthquakes - 06/09/2013 22:42

Perhaps this mornings shake was caused by blasting? Would blasting in a quarry or tunnel cause that much movement? I heard/felt it was possibly sourced somewhere to the south of Warrawee/Turramurra... The shake/jolt really was quite distinct underfoot - I was standing on a concrete slab driveway at the time.

Re: Earthquakes - 06/09/2013 23:07

Hi again perrywinkle wink
Quarry blasts, (fracking), fault splits/shifts and several other obscure things can cause 'under-foot' shudders, jolts etc..
One of our recent tremors felt like something had thumped upwards under the house...it was a bit disconcerting.
Have there been any reports in your local news about what possibly caused this movement you felt?
My guess is that it was something produced under ground level, and if you don't happen to have a quarry/tunnel blasting exercise going on within approx 5kms (just a rough guess), there maybe an outside chance it may have been a fault jitter, unless otherwise formally explained by an authority (gvnmt, mining co., or other).
Curious, isn't it?

Cheers, Duck.

M6.5 Guatemala (and aftershocks) on land and has the potential to be problematic and damaging for the communities there. Though it is about 64kms deep, it still is strong enough to have caused issues.

Re: Earthquakes - 08/09/2013 10:31

Ok...getting a little time to jot some notes here.

There is still some moderate (M5 region) plate movements in the Pacific. This, to me, is a sign that the plate has unfinished 'business' currently and we may see some more M5's popping up along the western side of the ROF and the odd one dotted down the west coasts of Central America, Chile, some of the islands NE of Australia, the Aleutians (Alaska) and New Zealand (particularly the South Island) . Note on the NZ link that the region around the Cook Strait is still active.

The Banda Sea has also come up with another M5+ (M5.7 to be exact, 137kms deep), which to me shows some deeper plate movements are still possibly going to produce more movements in the M5 region. To the NW of OZ (Indonesia) has also come up with an M4.6 (fairly shallow), with maybe another to occur in this general region.

Fiji's M4.6 at 507kms deep, has me feeling that this deep movement over a short time may go on to produce some other movements in the islands regions.

Arkansas and surrounds have been experiencing fairly regular tremors in the last week (those which have been included on the Global Incident Map). Apparently there have been a few more tremors than these recordings and what concerns me is the effect these movements may be having on the Louisiana sinkhole (this problem is still increasing in size).
The New Madrid Fault Line and the San Andreas are being closely watched by the folks in the U.S.. The minor fault lines experiencing small movements may be indicators of a parent fault jittering...?
I still get a feeling that L.A.. down to San Diego; San Francisco and west of Eureka, California, be vulnerable spots regarding possible (maybe) moderate tremors...just a feeling.
Yellowstone has had a couple of tremors lately and I feel there may be another to come. Yellowstone seismo's do show moderately regular subtle (and some not so subtle) movements. Given the nature of Yellowstone being what it is, this is not to be unexpected.

That region of the Mediterranean, including Western Turkey, Crete and the surrounding seas, have rattled like I felt it would with a couple of moderate (M5'sh) EQ's.
Italy has had smaller ones intermittently though I still feel they may experience a moderate tremor in the near future (maybe wrong).

The far ends and south of the Himalayas is jittering with moderate EQ's and I feel this will continue. The northern reaches of India are sticking with me regarding the potential of landslips, ground cracks (ground level alterations here and there). They have had some water issues which have added to this problem.

I get a feeling that SE/SSE and central'ish China may experience some movement too.

On the home front, I reckon SA, Vic and NSW may get the odd rattle (M2+) in the short term. WA (SW) will feel more small tremors.

Anyway folks, as I always say, the above are just feelings not predictions, and I'll stop here (even though there is more I could jot here) as I don't want to 'bla-bla' on smile

For the moment, Duck.

Re: Earthquakes - 09/09/2013 13:29

Okey dokey...a small wrap-up of what's been going on on the earthquake front...and those I anticipated...

Yellowstone has come up with the M3 I was suspecting;
Afghanistan has come up with the M5's I also anticipated;
The regions around Greece, Crete and the Mediterranean in general have been consistently rattling with small and moderate tremors;
The Tasman Sea NE of Tassie has come up with an M3 yesterday, to tie in with my suspicions regarding movements in the Tasman Sea from NZ to the east coast of Oz;
Can't work out perrywinkle's tremor felt a couple of days ago, though a Facebook page of the Hunter Valley Police may have mentioned a tremor (can't access this Page as I don't have Facebook);
( Geoscience is starting to put up tremors from the last couple of days on their site)

The west coast of Central America has produced a couple of M5's (+'s);
The western side of the ROF has come up with M5's from the Kuril Islands down to Indonesia (near top of Australia);
The California coast, particularly near west of Eureka (M3), has been continuing to rattle with tremors;
Chile and surrounds have been coming up with M5's and lesser EQ's.

Lower Australia - these seismo's and these seismo's representing some of the seismo's and movements in lower Australia, have been showing movements, some quite distinctive, and I'm waiting to see if Geoscience records any tremors in relation to these movements.

Puerto Rico has been rather unsettled, as has the Alaskan mainland. The Aleutians have calmed for the moment....

That "T" zone in south/central of the U.S. is still drawing me to it for more issues with tremors. Still not discounting the eastern side of the U.S. too.

I'm getting a feeling that we may see another substantial EQ offshore somewhere and again on land, maybe involving villages/hillsides/forest-jungle kind of area...?

I also get a feeling that the Atlantic may 'play-up' in the very near future...?

Anyway, I know I've missed some 'bits', but for now,
Duck.

Re: Earthquakes - 11/09/2013 09:36

"Scientists study Gippsland earthquake hotspot" - ABC News - reporter Jenni Henderson Posted Tue 10 Sep 2013, 3:01pm AEST

This report caught this ol' Victorian Duck's eye.
As many of you know, I have often rattled on about 'feelings' regarding tremors and other movements in the east and SE of my local homeland. My gut (intuition) has led me to believe or suspect there is more to the 'story/ies' than meets the 'eye', regarding what may be going on underfoot (and afar influence).

Now, we are one of many regions worldwide who are feeling the effects and sharing experiences regarding earth movements, and some regions have some fairly serious issues with this. Currently, for example, the Mediterranean general region, Alaska and the U.S. (to name a few) seem to be constantly rumbling with tremors, unlike Victoria.

Since the 1/1/2009, it is reported in the above ABC article that there have been 700 tremors/quakes recorded in Victoria alone. Nationally there have been 2355 to date (data retrieved from the Geoscience data base/records) . Now, if my calculations are correct, Vic has had a 29% 'share' in the total of these national figures.

Please note though - the figures were representative of quakes in the "Australia region" of Geoscience data. Some of Tasmania's records may come up on a different search for "Australia and region". If I did this search, Australia's neighboring countries EQ's, such as Indonesia and others, would have been included in the figures too. So, the actual % of Vic's EQ's, of the whole figure set, may be slightly out).

General possible causes of tremors and quakes worldwide??

Stress fractures (strain on sections and ends of faults)
Plate edge pressures on the main plate (distressing faults and ‘weak’ points)
Upward, sideways and other angle pressures from shifts in energy released from plate/crustal shifts;
Volcanic activity (including gaseous releases);
Magma pool movements;
Explosions, natural and manmade;
Forces on land, example – the Himalayas (e.g. mountain building)
Vent releases (of varying degrees, maybe from pressure build up from ‘parent’ source)
Water/tidal pressures on vulnerable ‘spots’, including faults;
Fracking/resource demands and operations (as may be an issue in the U.S. for example)
Lunar/solar influences……and so on.

As far as Victoria goes, my (amateur) feelings are that the article mentioned above may relate to the scientists possibly finding that the tremendous number of larger earthquakes in the last 6 years or so worldwide, have had the effect of placing extra pressures on all of the world’s plates, which leaves Australia generally not immune to fault issues, land deviations and earthquakes of varying magnitudes.

90% of my own theory of why the regions, mentioned in the article, have seemingly increased activity on the EQ front, is that a majority of this may be due to plate movements and pressures emanating from the Pacific, Bass Strait, Tasman Sea and the below/surrounding the plate edge south of Bass Strait/Tasmania/South Oz, as well as the effects of the nearby and worldwide major quake activity. The other 10% of my amateur theory is written in an email to self, dating back to early May 2013. I would actually like to run this mini theory past a seismologist/geologist/scientist before I jot them here. My ‘10%’ ideas may be wrong. Other reasons could be minute %’s of a few of the other reasons for EQ’s mentioned in my list above….?

South Australia, NSW and Western Australia, Tasmania (and even the NT by degrees) show earthquake activity on a seemingly regular basis, as does Victoria.

As always, I will be very interested to see what the scientists conclude in their investigations as to the reasons for increased EQ activity in Victoria (as per the ABC article) and I wonder if any of my amateur theories hold true in any way. Will wait and see.

For the moment, Duck.

Re: Earthquakes - 12/09/2013 23:24

The general region of the western side of the ROF has, as I anticipated (unfortunately) been quite active today (last 24 hours). I had a feeling that, as I said in a previous post, that the ROF (and Mother Earth) has some unfinished business in the Pacific in the short term.
The Pacific/Antarctic Ridge which came up with an M4.8 four hours ago, is situated on a 'ridge' (for want of an appropriate word) which runs in a westerly (NW) fashion directly up to where the near Fiji M4.5 occurred two hours beforehand. This 'line' and quake in Fiji may be not connected though...just a curious positioning of the two quakes (in my mind anyway).

On the home front, and if I have read the local seimo's correctly, there has been a fair bit of minor activity showing up on such in the last 24 hours or so. I actually felt one of the 'vibrations' registered on the SE Vic seismo today. Could this be a precursor to a 'felt' tremor? Will wait and see...
I'm guessing the folks in Darwin may have felt a bit of a rumble with the Banda Sea EQ today?

The Chile/Argentina regions have continued to be active too.

Italy came up with the moderate quake I felt it might today - M4.4.

Afghanistan is still reverberating with tremors in the Hindu Kush region.

I get a feeling that some 'energy' is creeping toward the British regions again. The English Channel is sticking with me a little for a smallish tremor, but could be wrong. Scotland is also drawing my thoughts to it a wee bit too.

Anyway, it's been a long and busy day today, so I may be more focused tomorrow folks.
Cheers for the moment, Duck.

Re: Earthquakes - 13/09/2013 18:27

Some folks in the U.S. are currently wide awake and watching the seismo's around Yellowstone. See here - multiple seismo's Yelowstone region to see current activity (it is about 3am in this region atm (?).
They feel there may be a new swarm (including in the number of small tremors, what they call ghost tremors. These tremors don't show up on the Global Incident Map necessarily).
This perceived new swarm corresponds with the swarm, up till now, occurring at the Long Valley Caldera (Mammoth Mountain) to the SW in California.
These swarms may only be indicative of temporary 'jiggles' or they may (?) indicate the potential of a moderate tremor...will have to wait and see. Yellowstone appears to have experienced a few M3'ish tremors recently (a little more than usual??).

Arkansas had another M2+ today, to add to the recent collection of this region and its neighbours. This, to me, seems to be more than the 'usual' number of movements. This is a region (part of the "T" zone) I am continually drawn to for the potential of a heightened number of tremors. As with Yellowstone, for example, there are more smaller tremors not always noted on the Global Incident Map.

Melbourne's SE seismo's have been jittering intermittently still. SA, NSW and WA are also experiencing similar movements.....

For now, decrepit Duck (slipping lower back disc crazy )

Re: Earthquakes - 14/09/2013 19:28

Had a nice bang down here near Wanaka yesterday.. which doesn't really mean a lot in the mainstream, but combined with Seddon which is still setting my phone off with every shake in a moderate range (ie: 3.5+) it is giving me a little concern. The quakes have been propogating south along the Alpine fault (NZ if you haven't already guessed) and after going through Christchurch.. whatever happens will happen I suppose.
Posted by: duckweather

Re: Earthquakes - 14/09/2013 21:28

Hi Dale.
The movements in NZ are not surprising (I feel) considering the recent larger movements near/in Cook Strait.
As you said, considerable fault line running NNE to the SSW of NZ, and near you SSW, will be unsettled for some time to come. It is understandable that the movements you are feeling and the other M3'ishes continuing to crop up along the fault line can leave you a little unnerved.
The quakes which tend to 'make' the mainstream media (very generally speaking) are the ones which have 'notable' impacts in communities and the nearest major cities tend to be in the news a little more than smaller or more remote communities, unfortunately.
The whole of the Pacific is somewhat unsettled and is activating in series' of movements. I get a feeling still, that a considerably sized EQ may occur in the Pacific in the short term.
Anyway, for the moment this ol' Duck is a bit dopey today because of a rather sore back, so I haven't been very 'tuned in' today. I'll jot more when the ol' brain fog has cleared wink
Posted by: duckweather

Re: Earthquakes - 15/09/2013 12:39

As I suspected last night, the ROF on the western side has fired up again. I failed to mention (brain fog) that I was honing in on the whole western side of ROF for some M5 and M5+ movement.
The Yap region which came up with a substantial movement a day or so ago got me thinking that the Pacific plate 'meant business' with short term future (now) movements, as this region is slightly east of the main edge of the Pacific plate. It is also a region which I envision as a 'delicate' or susceptible part of the western part of the plate, which I feel if it moves there is some serious energy to be expelled along the greater western edge of the Pacific plate. The current quakes are the follow on from this movement. (My amateur opinion folks).

I feel there is more to come in the islands around Fiji, Samoa and other island nations.

The west coastal regions (maybe Chile - vast region) and the west coast of America, Central America and Alaska) may also experience the odd moderate EQ's too.....will see.

For the moment, Duck.

Posted by: duckweather

Re: Earthquakes - 16/09/2013 09:57

The ROF has been playing up quite substantially recently and up till now.
As I felt may happen, the energy seems to have translated through to the south of China, traveling west through the Himalayas (one region I feel is susceptible to movement from the Pacific energy and from the Indian Ocean/India movements).

I am still 'watching' Yellowstone. A small tremor has occurred not far to the NW (in western Montana) of Yellowstone, which to me is a signal that this region may feel some more movement (apart from the usual 'background' rumbles of Yellowstone).
The coast of California, particularly near Eureka and down through to southern Cali, may still feel a couple of rumbles of maybe M3's (outside chance of an M3+).

The Aleutian Islands have rattled considerably to with the shuffling of the Pacific plate.

I am feeling that these considerable movements in the ROF may further energize some of the volcanoes around the Pacific region.

Central America, namely central on land, came up with an M5, as I felt it would, unfortunately.

The Mediterranean followed on suit from the many shifts in the Pacific, directly after this activity - another instance I felt may occur. Watch for movements in the Mediterranean when the ROF acts up substantially.

Hawaii seems to respond with tremors when the rest of the ROF has moderate to larger movements. Hawaii is somewhat 'connected' all the way over to Kamchatka, via a volcanic/and other chain, and is also seems to be influence somewhat by trenches/sea floor deviations which travel east to the American (including Central American) west coast.
Though, Hawaii being a set of sort of self-contained volcanic islands, can organize its own sets of tremors/EQ's through its own volcanic activity.

The Dominican Republic regions have been quite active lately and may continue to do so.

The Canadian west coast has been relatively quiet lately, but I feel they may experience some movement in their islands offshore from Prince Rupert down to Vancouver somewhere.

Remember all of the above feelings are not predictions.

For the moment, Duck.

Re: Earthquakes - 16/09/2013 13:48

Hi Duckweather, and a good day for it where I live!
It is good that you mention Western Canada as I was planning to ask you your opinion about coastal British Columbia. I grew up there and from time to time there was talk about The Big One. Earthquakes you can feel are not that common there. Don't know if that makes any difference regarding pressure build-ups and the like.
Always thought we were on the same fault line as California but is that true?
Anyways, the last area I lived in, the buildings were mostly erected over bog ground, which makes for a potentially disastrous scenario.
Posted by: duckweather

Re: Earthquakes - 16/09/2013 17:34

Hi Juno.
The western coastline of the British Columbian regions is a unique region where there are several types of plate movements all in one 'package'.
This means that the plates in this region can in some spots subduct (one goes under another), grind past each other, pull apart from each other and/or push against each other.

The Queen Charlotte Islands' large quake, not so long ago, and all of the aftershocks (continuing movements) were testament to the fragility and potential for such movements in relation to the various plates behaviours there.
For some really interesting info on the western coastal region, have a look at Natural Resources Canada "Background on Earthquakes in Western Canada".

Also, have a look at the image below, where you can see the plate edges (long red lines), and the complex plate zones of Canada - offshore, which continue on from the United States major fault lines, and up through to and around Alaska. (Cascadia Fault Line)
The small hair-like red lines are 'smaller' fault lines.
The coloured areas are graduated from blue through to red, meaning potential hazard zones (red meaning considerable hazardous areas). Obviously the colours are representative of the U.S. states and not Canada, but you can see where the levels of hazard can overlap into Canada.


This image uploaded with ImageShack and the image courtesy of the USGS maps

The 'big one' for Canada (west coast) may have been the M8.1 in 1949, where a 500 km long part of the Queen Charlotte fault fractured (this info can be found in the link to the Natural resources Canada link above).

Building homes on 'soft' ground in earthquake prone areas has always unnerved me a little. Liquifaction, subsidence, landslips, amongst other things, are some potential scenarios which I may be a bit wary of.
Though, even on 'solid' ground, the impact of an earthquake can throw up these potentials too (depending on the area), as well as ground drops/rise, cracks...the list can go on...

I grew up on the land of old farms. We thought it was good old solid clay and rock 'soil'. One day we remembered there was a natural waterway beneath our property, when a very busy bob-cat (big digger) started to sink and tilt a bit. The vibration of the digger brought the water table up (liquifaction) and, needless to say, the digging work had to stop until the water table went down again; an engineer checked the building structure (for subsidence) and we all got over our nightmares of being sucked into the "centre of the earth" (quote from the then 6 y.o. Duck(ling))

Each ground base, whether it be rock, clay, sand, bog, reclaimed land (from the sea), or other mix (geologically speaking) has its' own response/reaction regarding earthquake movements etc..

Anyway, my amateur and un-scientific feeling about the west coast of British Columbia is this....

Considering the above bit of info and adding a few of my feelings to the mix, I reckon that Canada west-coast is less likely (in number) than regions like Japan, Indonesia or the Pacific Islands (NE of the Australian mainland), for example/s to suffer very regular moderate quakes. But, this does not mean it is immune to tremors/quakes (not many places in the world are).
Since the recent (in last year) major movements in the Queen Charlotte Islands, Canada west-coast has been rather passive compared to many other regions surrounding the Pacific plate.
There may be intermittent tremors (M2, M3), with a slight chance for a moderate to larger tremor/EQ in relation to the recent/current heightened activity with the ROF. But this is just a feeling not a prediction.

The Pacific plate, in general, has rather regular locations for the larger and moderate quakes to occur. Sometimes a surprise region/s crops up with an EQ, which can draw to our to and remind us that the oceans and some lands have pressure points quietly waiting to 'give' when that pressure is too much to withstand. Some weaker spots are known to be (exist) and I feel there are others to be discovered.

Oh Duck has gabbled on again blush
Remember, I am not a scientist - I am just a lay-person, whose words should not be considered prophetic when it comes to earthquakes/tremors and when they may or may not occur.

As I usually say - peace and safety to all.
....Duck.

Re: Earthquakes - 17/09/2013 01:48

Hi Duckweather, wow thank you for your thoughtful reply.
First off, that 8.1 was before my time, but strangely enough my mom mentioned this to me the last time I visited. She was walking up the lane by her house and suddenly the ground began to move in waves, just rolling and rolling toward her. She still vivdly recalls her terror and incomprehension. Many years later I went down into my grandparents basement for the first time and their floor still bore the damage of that earthquake, like it had been caught in a moment of rolling and just froze that way. Built on bog ground. Thank you for putting that perspective on it.
I never knew it had been that high up the scale.
I take your point about ground reactions---whatever we build on will be affected. Personally I hate the idea of subsidence, it just seems like a stealthy and overwhelming force. I would love to live in a pole home on the side of a hill but that idea of soil losing its cohesion scares me. Of course here in Australia the danger is from too much rain rather than EQs.
On that map you provided, it is fascinating to see the hotspots, and wonder, for instance, how such a huge population like LA can live with frequent tremors. But it is a gamble, isn't it?
People do take EQ preparedness a lot more seriously now in Vancouver and Vancouver Island. But who knows? You may be correct in saying the Big One has already come and gone, and I will take some comfort in that idea (and maybe share it with my family).
Obviously Duckweather you put time and effort into studying the subject, and in a wholistic sense you may be strengthening your intuition, through observation.
I just stumbled on this thread lately and it is good to see people try to make sense of EQs.

Re: Earthquakes - 17/09/2013 10:31

Cheers to you Juno.
The super quakes from our histories offer many interesting (and some horrible) insights, info and local stories about how a community can be impacted by such.
Mother Nature/Earth can be a very powerful force and we humans can only perhaps gain greater awareness and preparedness for ourselves, our families and community, regarding what may or may not happen to our lands and our peoples.

Many who have lived through large earthquake events (and some of the moderate ones) can be left with fear of when the next one may occur. If one has experienced personal loss and hardship following a large quake, this experience can be carried in the psyche for a lifetime, in varying degrees and subsequent effect.
PTSD (post traumatic stress disorder), again in varying degrees, can be a fairly common response to a major, life changing event. Many folks today, who have experienced such an event, can feel an anxiety (ranging from subtle to very obtuse) and an uneasy anticipation that a troublesome EQ event may happen to them again.

But, regarding future larger EQ events, I feel that no one can say with absolute and undeniable certainty when and where another quake like the Alaskan great quake of 1964, Japan's M9 in 2011, Canada's 1949 8.1, Chile's quake, for example, may occur again. We can presume that certain areas may be vulnerable, given past experience, but maybe cannot conclude that the same disaster will revisit known past problem regions.
What the scientists and many other folks aim to do is keep an eye on current 'behaviours' of the planet (and other possible influences), combined with past knowledge of events, and try to anticipate where potential problem areas may be brewing or have potential to arise.

There is definitely greater awareness of the impact of earthquakes 'these days' and many more people are tuning in to what may or may not happen in their respective regions.
Awareness is important, but so too is not to live in fear. Preparedness is important, but not let fear dictate how you live and carry on with life.

Whenever I 'talk' about EQ's here, I am constantly aware of those communities which are poorly impacted by such. I can only hope that whatever I note in this thread is viewed as perhaps interesting, informative and by no means intended as prophetic (as I said in last post). When people's emotional and/or physical well-being is at stake, one does not play on or create fear and anxiety. I value awareness, education and care for all communities.

For the moment Duck.

Re: Earthquakes - 17/09/2013 17:15

Just a quick note for the moment...
Have a look at this link to the National Data Buoy Centre's map of all the buoys deployed around the world. The red diamonds represent buoys that are not currently giving readings and the yellow ones are 'live'.

Is it my imagination that there seems to be many more live buoys deployed (extra ones)? The U.S. eastern states and up through Canada; some spots in the Pacific; the west coast of the U.S. and Canada, and the British region, for example.

Curious....just a little.

Hi Duckweather, in my opinion the most traumatic ongoing EQ event was begun with Japan M9 in 2011.
We were talking about planning and knowledge about faults, and how this should be incorporated into structural planning. As far as I can glean, some bypassing of commen sense (not to mention engineering experience) may have occured in Japan and Fukushima in particular. What a mess. Talk about suffering...we can only wait and see how catastrophic this will turn out.
A lot of aging infrastructure around the world vulnerable to EQ.
Sometimes I am amazed to read about ancient buildings which have withstood all nature can throw against them.
I don't know what to make of all those yellow live buoys. Is that unusual?

Re: Earthquakes - 18/09/2013 08:09

Hi Juno.
The ongoing effects (aftermath) of Japan's quake and the Fukushima 'fallout' especially is constantly in the news (and elsewhere). And, because this fallout appears to have the potential of affecting many communities and sea-life, apart from Japan, it has the world community on edge.
Just on the subject of Japan, I stumbled across an article dated September 13, 2013 on Space Daily - "Japan deep sea drilling boat casts off to find quakes" .

The ancients, who built the amazing structures, for example the beautiful structures like the Acropolis and other solid wonders, I imagine would be very proud of their engineering/architectural feats if they were able to see how these amazing things have stood the test of time.
Even when the Pyramids were constructed, the land was surveyed for geological soundness by the Pharaohs and those charged with building these incredible structures.
Modern man may (in some places) have made some errors regarding building various types of structures over particularly major fault lines or in 'known' vulnerable locations....

The buoys seen on the National Data Buoy Center maps, are representative of live (yellow) beacons, which record local conditions such as;
* water column height (buoys in oceans and seas)
* wave regularity and height
* buoy location
* winds
* atmospheric temperature
* air temperature...and so on.

They are mostly positioned in water/sea, but some appear to be inland and/or near coastlines in some countries.

Now that I have looked at the map again, there are definitely more live buoys being added here and there.
This may just mean that there has been a decision to activate some and deploy some new ones to monitor the conditions for these areas. In my mind, I feel that the new activations and deployments are due to an increasing focus on conditions in these regions.
Where I 'see' new ones being deployed, for example, are near the regions of NW Alaska, east coast of South America, some in the Atlantic, NE of New Zealand, from Norway-through and down to Spain, and those places I mentioned in a previous post.
Some of these maybe newly activated existing buoys and some definitely seem to be new deployments.

For now, Duck....

Re: Earthquakes - 19/09/2013 13:55

Koorda in Western Australia has been experiencing an EQ/tremor swarm in the last couple of days. see Geoscience records here

The Mariana Trench (Islands) region has been a bit of a central point of deep movement (Pacific plate subduction to the west under the Mariana), as I felt/said in a previous post that if this region moves deeply then some equally deep'ish and some shallower EQ's will appear from the PNG region (up past Taiwan to the west) and up (through Japan) through to Kamchatka. There may be the potential of more M4+'s occurring in this western Pacific/ROF region.

I haven't had much time to focus on EQ's since yesterday morning - maybe tonight I'll get time to add some more bits and pieces of info....

For the moment, Duck.
Posted by: duckweather

Re: Earthquakes - 19/09/2013 22:22

The general region near the Mariana's is still showing that movement I anticipated and have been gabbling on about.

L.A., California caught my eye yesterday (and recently, generally speaking) and is on of those regions I have mentioned recently for potential tremors. San Francisco is another I have been watching a bit too.
L.A. was jittering with some tremors in the last 48 hours or so and there was even a mini cluster at one point. I had a gut feeling that this region was brewing for a potential M4, and is now experiencing some rumbles, a couple so far just a bit under M4.
These EQ's are very shallow and the folks there will definitely be feeling these movements.
The most recent (last 5 or so) tremors in the whole of the California region have been/are near L.A., meaning the energy has 'focused' there. This is near the San Andreas Fault. About 10 of the smaller tremors today have been in this general region (and on, or on either side of the San Andreas).

For the moment, Duck.

Re: Earthquakes - 20/09/2013 10:33

Hi folks.

The M5.1 which has registered in northern Quinghai, China 2 hours ago has actually occurred, even though no other agencies (re: Global Incident Map usual several agencies) apart from the Chinese seismological agencies and the European CSEM-EMSC agency have recorded its occurrence.
Here is a brief news report from xinhuanet.com Chinese News which confirms the quake.

The western side of the ROF is still coming up with M4+'s as I anticipated and Alaska (Aleutians) is also responding to this movement.

My feeling is that there is the subduction movement (westerly energy) going on in that region west of the Pacific (involving Japan, Mariana's, affecting Taiwan, Philippines and so on) and a NNW energy running up the top of the Pacific Plate (affecting Alaska, Aleutians). Corresponding with this movement, the west coast of the U.S. (San Diego, California, up and through to Washington) seems to me to be experiencing the eastern part of the plate moving in moments to the NNW/N towards Alaska (involving the San Andreas Fault generally).

I get a feeling the east coast edge of the Pacific Plate is being pushed/pulled in this direction (like sliding in small ways up the coast) and maybe being slightly pulled west as it goes.

Canada west coast may not be moving too much currently, because this energy (mentioned above) may be mildly bypassing this region for the moment.

In my mind, the quake in China may (or may not) be (?) associated with the pressures emanating from the Pacific...and maybe energy coming up from the Himalayas.

Tonga and the surrounding Pacific Islands may come up with some more tremors/EQ's M3++(?), maybe one of the islands/or off shore may come up with an M5+.

If you look at the plate deviations/edges on the world map, the Tonga and surrounding islands regions are, what I call, on part of the Pacific Plate that looks like an ear. I generally feel that with the current movements in the Pacific Plate, I've mentioned above, that this region may be somewhat vulnerable to the plate movements (whatever the reasons for the quakes there, e.g. subduction and/or other types of movements).

Anyway, what I have jotted above (and below) are just thoughts and I maybe wrong in my observations. They are not predictions or of true scientific knowledge.

I get a feeling that we may see a sizable EQ in the Pacific soon. I'm hedging my feelings there along the western ROF, but a part of me is not discounting the eastern side - from the centre-east to the lower east of the Pacific region....I am probably wrong....

For now, Duck....who's had too many coffee's this morning...

The above image (uploaded with ImageShack and image courtesy of the Global Incident map) shows the Austria (M4.5), Greece (M4.3) and Central Turkey (M3) earthquakes which occurred within minutes of each other. I personally feel the energy to produce these tremors is connected, even considering the many kilometers between them. I get a feeling that this is a 'central' (or two) source of energy that is filtering through the Mediterranean and up through to regions like Austria and possibly over to the eastern side of Spain.
The Atlantic may be playing its part too, but I tend to feel that it is emanating from around the Greece/Italy/Western Turkey regions....?

My suspicions about the lower east coast of the U.S., possibly feeling a tremor were actually correct when South Carolina came up with an M2 some hours ago. Maybe another eastern state could also come up with a tremor (Atlantic related).

You guys know me...I'll probably add another post (a third for today) a little later... smile

I didn't think that California, below L.A., near San Diego, had finished with its movements. It is currently experiencing a significant earthquake swarm.

Christchurch has had an M4.1 and Seddon is till moving fairly regularly, with the odd tremor to the SSE. See here - Christchurch M4.1 and here - Geonet other quakes

See here - Earthquake Report for other quakes/tremors global

Kyushu, Japan has just had an M5 and the centre/east of the ROF, and Chiapas, Mexico has come up with two moderate quakes.
Chile has also come up with several M3+'s.

If you want to keep up with California's many tremors (updating map as they occur) go to the USGS page and refine the "Latest Earthquakes" map using the tools in the top right of the map, after you have clicked on the "Latest Earthquakes" on the main page, to refine the map down to the Californian region only.

Re: Earthquakes - 21/09/2013 12:53

The sizable and deep quake of the Flores Sea, Indonesia, may have been the larger quake I was feeling may occur in the west of the 'Pacific'. I felt something was brewing.
USGS info on this event
Not sure of what affect this quake has has on communities nearby yet.

The folks in the north of Oz will have felt this movement. Thank goodness it was not more shallow. This deep movement is indicative (in my mind) of that deep crustal movement occurring in the western ROF around the Mariana's to the NE.
There may be some more shallower quakes to come, perhaps in the M4+ region in the surrounding areas and perhaps further up the west of the ROF. Maybe the NW of the OZ continent, travelling west along the Indonesian countries may also experience some movement....as may the Pacific Islands/PNG to the east....will see.

As many of you have gathered, I mention Yellowstone a fair bit in this thread. It is a beautiful and one of my favorite places in the world.
Now...the M5 which just occurred in Wyoming, SE of the Yellowstone region (and close to the Rocky Mountains), does not surprise me that it has happened. Utah also experienced an M4 1 minute before the Wyoming EQ.
Now some of you may think I am strange or you can believe me or nay wink , but I felt that there was an 'energy' which was to be expended away from Yellowstone to the SE or SSE not far from Yellowstone. I found, though I was following Yellowstone's records of it's rattles, I was being 'drawn' away from it and to the peripheral regions (SE/SSE) for a moderate movement...(that's enough bla bla from me).

Anyway, here's a link to the Earthquake Report's EQ list with reports from locals in Wyoming and Mexico on their respective EQ's today.

For now, Duck.

Re: Earthquakes - 22/09/2013 12:41

Well Canada received a wee bit of a surprise with 2 reasonable EQ's occurring at opposite ends of their country.
The Queen Charlotte islands movement was, unfortunately, not a really surprising movement, considering all that has been going on in the Pacific. As I mentioned in a previous post chatting with Juno, who has family living in the western part of Canada, the west had been quite quiet for a while, but I felt that was somewhat temporary, with the Queen Charlotte sitting in/near that Cascadia faulting region, that it would soon respond in some way to the pressures/movements in the Pacific.
The east of Canada's EQ in the Gaspe Peninsula, is about 200kms east of Rimouski, where some time ago - and to the west slightly of this community, was a region which had experienced some tremors and I had been 'watching' for a while (and back towards Montreal). Further east again, towards the SE of Newfoundland and Labrador (towards the Atlantic), was another region I had been watching for movements back 'then'. Having said all that, I would not be surprised if another movement (maybe smaller) may occur along the waterway back to the west from the Gaspe Peninsula...?

The 'energy' from the general Mediterranean region is still occasionally splaying in a 'curve' to the W/NW up through the France, Poland (and other areas). This is just my feeling, not a factual scientific observation.

Lower Australia, along the southern states, are experiencing some movements, which I feel is relevant to the Indian Ocean, The Great Australian Bight and potentially Bass Strait. I still feel some sort of influence from the Tasman Sea (which is between NZ and the east coast of Australia) in any coastal related movements in the lower half of the east coast of Australia.

Japan is still experiencing movements in those regions which we don't want to see such happening - for the Japanese folks and others.

I get a feeling, now that the Queen Charlotte's have moved now, that the Gulf of Alaska and surrounds may come up with a moderate (M4+?) at some point soon...will see.

A tremor (M2.3) has been recorded in Victoria in Glenmaggie, SE.
I noticed activity on the seismo's before this 1am tremor (23/9) and was not surprised to see one of the movements recorded.
There is still movement happening on the Gippy seismo and I wouldn't be surprised if we see another tremor - something doesn't feel 'right'. The seismo has been showing some fairly regular movements in the last few days.

There have been some 'interesting' EQ's since my last post on the Vic weather thread at 1am this morning (the temperature seemed to be rising here instead of decreasing - 21+ degrees celsius...).

The regions north of the Australian mainland, namely PNG and a couple of Indonesian regions experienced M5's and an M5+ (New Ireland PNG) - all reasonably shallow at under 100kms deep. I had a feeling (as I mentioned in previous posts) that there would be the possibility of some shallower (than the several deep quakes recently) EQ's in the short term)) following on from the deep quakes in the west of the Pacific (e.g. the Mariana Islands and near Guam).

Yellowstone has come up with another smaller movement; Lone Grove, Oklahoma has had several movements (one recorded at M3.2 at 5kms deep); Bonin Islands, Japan has had a very deep M4.8; White Island, New Zealand had a fairly deep (200+kms) tremor (volcanic?); New Zealand remains reasonably active in several places and many of the quakes around the planet have been shallow predominantly between 0 and 50kms deep, others between 51 and 100kms deep (roughly).

The west of Canada (off shore) had an M3.5 (Pacific Ocean side) at 196kms deep.

The best I can offer here for the moment are links to some sites with updating info for the moment.

USGS event page

page 2 of Earthquake Report

Main page of Earthquake Report

This is not about me of course, but the buoy below Pakistan was what was bothering me, apart from being strongly drawn to this general region. The EQ on the Carlsberg Ridge is on a 'fault' (plate edge) which runs (continues on) directly past where this Pakistan quake occurred.

Let's hope that there have been no casualties, but the potential impact of this quake; it's shallow depth and strength is enough to have definitely cause some potentially serious issues I would imagine.

A tremor registering M2.8 (USGS) in Alabama today was caused by a mining explosion - here's the USGS record of this incident/tremor

To keep up with how the Pakistan quake/s has affected communities there, refer to the "page 2" link in my above post, re: the Earthquake Report site.

The region near Eureka in California (which I mention a fair bit) has experienced an M3.5+ tremor. This one was just inland and just south of Eureka. There was another, an M3, just off shore and just SW of Eureka.

The earthquake(s) in Pakistan sent reverberations almost around the planet. Many of our seismo's responded with movements, some which looked like a fast heart beat and some registers on some seismo's looked like electric shocks. I wonder if this movement will 'upset' some 'vulnerable' zones/faults?

Maybe I've had one too many coffees already this morning, but while standing on my decking, looking east (beyond the Dandenong Ranges), I observed a hazy cloud transforming continually (but smoothly) through various presentations of gridding/ribbing. The grids formed in one direction (NE to SW) and then changed to a N/S angle. Several stretches of 'lines' formed, then dissipated. The top of the cloud formed some points, then hazed out.
Ok..you probably think this ol' Duck is delirious with caffeine/coffee...and you may be right smile But it caught my eye and may mean zilch regarding a potential tremor for this region (towards Gippsland)....

Hopefully no more casualties reported frown.

But also this quake has provided an unusual chance to study ocean sediments & the seafloor with much less expense and (presumably) at a higher resolution than before (depending on how deep it is at the location.

Posted by: duckweather

Re: Earthquakes - 25/09/2013 11:55

I agree with you Xavo.
Though the epicenter of the quake/s was on land, for the sea bed to respond tells me that the Carslberg Ridge quake before the Pakistan quake may have been a 'sign' or the precursor for the latter quake (and/or related). For the sea bed to rise, and this is where it becomes more interesting (if I can say that), the focus of studying this quake/s will not just be where the epicenter is. The energy force surrounding this activity must have been incredible. And, it appears to have been northward (?) bound.

Generally speaking, we humans being predominantly land dwellers, may tend to observe the land for cause and effect of earthquakes as they occur.
There is tending to be a greater included focus on the ocean beds 'these days' and how what goes on off land (at sea) is very important in providing info on what can occur on/in inland/offshore/coastal regions' quakes in some places.

As I mentioned in a previous post, there have been quite a few more buoys deployed in some ocean/sea (and onland) regions recently. This, to my mind, displays a perceived need to monitor the potential correlation between land and sea movements and inter-relationships.

This emergent land mass in the Arabian Sea is a reminder of these potentials' and that there can be more than meets the eye with on land EQ's.

I feel there may be more of these fascinating sea-born mounds and even volcanic vents to be discovered or could emerge in the future. The Atlantic, the western Pacific and possibly the Mediterranean regions (very general, large area) are a few examples of regions which, I feel, may have the potential to produce similar sea-bed occurrences.....

The death toll in Pakistan is terrible. And, I too hope that there will be no more loss of lives to be reported.

For now, Duck.

That M2.8 in Alabama may have been mine blasting and not an explosion...the U.S.G.S. still has it listed as an explosion, but after searching for information on this event, I can't find anything on any news channel which describes it as a local disaster event. Some locals, leaving comments on their local news sites, are not mentioning any industrial accident, but some are suspecting mine blasting in the area.

The SE of the Pacific Ocean, Tonga, Santa Cruz Islands and the Fiji regions have all come up with M4+'s. The SE Pacific was an M5.4 at 33kms deep. I suspected that some 'vulnerable' regions (including NE of Pakistan - Hindu Kush Afghanistan) may come up with some moderate EQ's. There may be more to come in the Pacific and the eastern side of the Mediterranean.
I am also still watching the Himalayan region.

between Bordertown and Renmark in S.A.,
NW of Victoria,
south (100 or so kms) of Griffith NSW,
near Cleve in S.A..

Re: Earthquakes - 26/09/2013 13:52

This the first chance I have had today to sit down and catch up on what's been happening on the earthquake front....

Peru's M7 caused landslides, house collapses and there may be miners trapped in a copper mine. Here's an article which is quite thorough in its description - "Peru to rescue copper miners reportedly trapped after quake" - Reuters

The Earthquake Report's listing of quakes/responses

USGS event summary

Some areas, apart from Peru (within that lowerSE section of the Pacific), which I felt may experience tremors/quakes within this general time frame (48 hours or so) - Near Gulf of Alaska; Canada east - near Rimouski and Montreal; The Atlantic; the general eastern Mediterranean region, west of Spain/Portugal, shallow'ish quakes in the Pacific Island regions and others.

Most of the quakes (about 95% roughly) have been on the shallower side of their depth - between 0 and 100 approx.
My feelings suggest that when we witness very deep quakes occurring, such as the Mariana's and the large quakes like Pakistan for example, that shallower quakes may be triggered (for varying reasons) globally, and particularly in vulnerable places.

As an unscientific comment and feeling, I think Canada's west coast is partially releasing some of the pressures being built up by all the movements in the Pacific and maybe the energy being exerted by the California plate movements (San Andreas as an example).

There may be a couple more M6's to occur, perhaps in the Pacific region and maybe related to the Atlantic, yet....? Even Iceland may come back into the picture (or within its general region) with a moderate tremor...will see.

Re: Earthquakes - 26/09/2013 17:53

At about 1.30 this morning somebody from Croydon in Melbourne's outer east, reported a deep ground rumble (on the Earthquake Report site) and appears in the ER section as ??M2.9.
Last night we had heavy rains and storm like conditions ripping through Vic and multiple flashes of lightning near the Croydon and outer areas.
But here's a funny thing. I too heard an explosive sound, like the clap of thunder after a lightning bolt....but there was no flash of light (I was awake at that time). The sound was strange (and just may have been electrified atmospheric phenomenon) and sounded like something 'rushing' (wooshing) past under foot and then an explosive boom.
Now...this may have been purely weather related, but it was rather different to any electrical storm activity I have experienced.
I will be interested to see if Geoscience notes any movements from down under, or whether it was just a weather effect.

Anyway, Mexico came up with a near M6 earlier, which may have been one of the M6's I was anticipating may occur today in the Pacific (re: last post). Click a previous post link to the Earthquake Report site for info on today's quake.

Hi GDL wink .
With the crazy weather we had here last night, I really couldn't say with any certainty that what I, and possibly the Croydon folks, heard early this morning, was a fault boom or an electrical atmospheric happening, but it was a weird sound.
We have had some interesting sounds emanating from 'below' in the last couple of years, and when the Lilydale fault boom occurred not that long ago, amongst other fault jitters, I actually wouldn't be surprised if there was some sort of movement last night. Even our 'local' seismo's have (and are) registering some continuing vibrations, the source of which may be continuing subtle reverberations from the major quakes occurring and/or the odd atmospheric conditions and/or the planets current plate agitations quietly affecting many lands and/or other subtle land/sea plate/faults gearing up for more small or other movements.
So, to be more succinct, the source of the noise 'we' heard last night is a little unclear (to me anyway).

Im not sure if people will laugh at this, but im going to write it anyway, I have been taking photos of these weird clouds that seem to happen about 2 weeks before an earthquake, people have even been ringing me up (word has got around that they seem to correlate) anyway, just thought it was an interesting, perhaps coincidental point to share!
I managed to find an article a few weeks ago by Ken Ring ( he, also mentioned these clouds and earthquakes too?) I had a photo of the biggest one ever and I know it sound like a cliche, but lost it when my house got struck by lightning and the computer blew up and I lost my hard drive) anyway it was 2 weeks before the Japan Earthquake and Tsunami, I have at least 6 people who can attest to this, as they saw it (the photo and the cloud that is), it stretched the whole length of the horizon form East to West and wide too it was like a barrel roll across the sky, does anyone no anything about these? Maybe it sounds a bit superstitious to scientific minded people.

Hi CaptainCirrus.
I, for one, would not laugh at what you have said in your post here.
As many who follow my posts, (and probably get sick of me saying such) talking about possible earthquake cloud appearances as potential precursors to earth movements, have gathered - I am interested in the possibility of anticipating some tremors/quakes observing the behaviours of the atmosphere (cloud and various vapor puffs/shapes).
Some tremors/quakes may occur from a general period of between 0 and 55 days from the appearance of some types of clouds.
Of course, all of this I cannot prove or guarantee, but I do believe in their existence in some circumstances.

There are scientists in China, Japan, Iran and other countries, who have described their observations of cloud formations in the shapes of long "snakes"; or waves (which are stationary, whilst other clouds glide on past them); or formations like leopard spots, strips, rainbow (vertical or horizontal or other angle) and so many other presentations.
Some of their observations have successfully predicted the occurrence of even some major earthquakes.

Here are just a couple of links with some info from the above-mentioned scientists/persons;
Bam Earthquake Pediction
Earthquake Clouds and Short Term Predictions

Also, look up "earthquake clouds" on Google Images and some of these clouds, as described by persons interested in and some who study the cloud phenomenon, can be found.

On another note, we just had a distinct vibration running up and through the floor of my house, which lasted for about 5 seconds. It is calm and quiet outside and we have no storm activity happening here yet (some due later tonight). And, this maybe a coincidence, but one of the seismo's movements in Vic seemed to correspond with us feeling this vibration.

Anyway, for now....Duck wink

The Times of India - "Pakistan gets three new islands following earthquake"

The emergence of small volcanic mounds in this part of the world is not uncommon, and some just wash away with tidal forces etc.. But these gaseous rocky formations may stay a little longer. I wonder what the sea bed looks like, to have been pressurized enough to lift the sea bed like this...?

Re: Earthquakes - 28/09/2013 15:10

The Lake Argyle region of the Northern Territory has just had (at about 2pm Sydney time) an M3.4.
Now you may think that I'm a bit weird or sometimes too 'left-of-centre', but I had a dream last night that from this approximate region and travelling east along the top of Oz, that there may be an M3 (from that NT region) across through the top of Qld., with a possible M4+ in the middle of this range across to the east coast.....
Now....I am more than likely wrong and a dream is just a dream (probably too many coffees before I went to bed last night) crazy

NT tremor here

Re: Earthquakes - 28/09/2013 18:03

Pakistan's EQ problems aren't over. I had a gut feeling this would be the case as the region just isn't stable yet.
They have just had an M6.8 at 40kms deep. There will be more movements to come unfortunately.

This movement has registered on our seismo's.

Re: Earthquakes - 28/09/2013 21:35

There's some substantial movement showing up as reverberations on our seismo's. My guess is it's NE or north of Australia (other country).
More soon, Duck.

Re: Earthquakes - 28/09/2013 21:50

extra; Just checked the Global Incidents Map and the Earthquake Report site and Tonga has had an M5.7 at 54kms deep.
And White Island, New Zealand has had an M4 and Hawera an M4.7.
The NZ quakes happened at the same time - Earthquake report

My direction of north or NE was a bit off with my suspicions (last post) of north or NE of the Oz mainland looking at the movements only on the seismo's.

Re: Earthquakes - 29/09/2013 10:16

Some posts back, I mentioned that there will be a possibility of more volcanic vents/mud volcanoes and similar protuberances emerging from the sea or land (also mentioning this is my blog some time ago).
This new article on EP is exactly about what I suspected we will see occurring, particularly as a result of what I feel is a wide spread stealthy movement happening with plate and volcanic activity in the Mediterranean regions and across to where Pakistan is experiencing their issues.
Regions where there are substantial energies being displaced or received, in my amateur opinion, are potential locations for emerging natural occurrences such as these mentioned in the article below.

"New volcanic eruption reported off the coast of Lazio Italy" -EP (has pics and a video)

I realize this post should be in the Volcano thread, but many of these occurrences can be related to earthquake activity.

Cheers for now, Duck.

Re: Earthquakes - 29/09/2013 18:56

As I type this, there is a new flurry of tremors occurring in California, with the largest so far being an M3+ in Southern Cali. Will be watching this...

No sooner had I put up that info about Italy in the previous post, a small series of tremors began around this region.

Another flurry of EQ's occurred north of Australia (Indonesia) today, with the quakes M4+'s occurring almost one after the other. This was some considerable movement.

More later, Duck.

Re: Earthquakes - 30/09/2013 11:13

A new sub marine eruption has occurred in the Red Sea - see here - Volcano Discovery for info.
Any future volcanic info I will put in the volcano thread, but I've decided to note this one here for today as this event seems (to me) curiously linked to the volcanic/EQ activity in/near Pakistan.
I have often 'felt' a deep energy spreading across the region from Pakistan and all the way over to the east of Spain. In the middle - the Mediterranean (remembering Italy's fumaroles) and the considering the whole picture, there seems to be a considerable amount of activity and energy moving all around this vast region....
Which, I feel, also involves the Arabian Sea and somewhat the possibility of the Upper/Middle Indian Ocean.


Anyway, for now (gotta go out) Duck.

Re: Earthquakes - 30/09/2013 13:37

Cheers CaptainCirrus wink

Another 'thing' you can look out for are cloud patterns on the satellite pics. But there needs to be cloud on these pics to see what may be going on down below with any activity in faults/plates which may be giving off 'signals' as to potential activity. (There are no guarantees of accurate observations with this method).
Using the satellite pics (for the moment in time - of a given day), I have managed to pre-empt some EQ's in PNG, Japan, New Zealand, the Pacific islands and Indonesia for example. Combined with this sometimes, the buoys off some locations show jitters pre some EQ's.
The bulk of my feelings regarding where EQ's may occur on the planet overall originate from pure gut feelings.

My 'methods' don't guarantee accuracy and I am no prophet and if and when I am correct with my observations - the challenge to myself of hopefully helping others with awareness of potential hazards, is worth anticipating some of the EQ's.

When you set up your blog, add a link in a future post and in your signature space which shows below your posts permanently.
I'm looking forward to seeing it wink

A short note on the Indian Ocean - there have been a couple of moderate quakes occurring in relation to this ocean (as a whole). From up near Pakistan (watch the Himalayas for movements), all the way down and sweeping around to under Australia (SE of Indian Ocean). Plate edges and trench involvement here. Maybe SE of South Africa (at sea) and maybe again south of Australia (at sea) could see some movement along the edges/trenches....?

Cheers for now, Duck.

This registered noticeably on our seismo's.

A tsunami message of "no expected tsunami" has been issued for now. But I feel there may be water disturbances.....

I had a horrible feeling that a larger quake was going to occur east of Australia.

Re: Earthquakes - 01/10/2013 00:00

The EQ activity has been happening all over the place today - the Atlantic, the Pacific, the Indian Ocean, the Southern Ocean, and some largish quakes at that.

It almost seems like a 'ping-pong' effect across the globe with the larger quakes and there has been a feeling of unsettledness all round.

With submarine and other volcanoes added to the mix, it's been a rather busy period lately.

Currently and since New Zealand's (Kermadecs) large quake and the quakes around (offshore) Australian regions, our seismo's appear to be still affected by these movements. Though, as far as Vic and SA goes (the seismo's I have been watching mainly at times today) there has been varying 'irritations' running through them, but we have severe (on and off) weather conditions at the moment, so this may also be having an affect of sorts on them too. Currently in Vic, a seismo north of Melbourne is showing a fairly consistent movement (like an almost constant vibration movement) which I can see in a glass of water. There have been some small sways and vibrations.

I still feel that the regions from Pakistan and over to Spain (and to the west, NW and SW of Spain too) are rather unsettled and we may see the odd M3+ in a few spots there. I also get a gut feeling that we may see an M5 (or 2??) in this vast region as it continues to be unsettled.

The general Chile region seems almost constantly active currently and we may see more M3+'s there (maybe an M5) and Central America (around Guatemala/Costa Rica/Mexico somewhere) we may see an M3+? at some point.

The "T"zone of the United States is still coming up with small tremors and may continue to do so sporadically. I'm getting an inkling that there may be an M3 (maybe M3+) in this region soon.

Anyway, I'm still watching San Francisco and the L.A. regions for movements around M2, M2+ and maybe an M3+ at some point...
Yellowstone may also come up with an M2 or maybe an M3 (+?).

All of the above are just feelings, not predictions.

Cheers for now, Duck.

Re: Earthquakes - 02/10/2013 10:50

A short note for the moment (been busy),

Iceland came up with an EQ in the last 24 hours, I was suspecting would occur. But this was not the only one. Here is an article I found this morning about not one quake/tremor but 1000 tremors in 6 days.
"Intense earthquake swarm offshore North Iceland - 1 000 quakes in 6 days"

The Atlantic is another region which has come up with the EQ's I was suspecting would happen. That general region of the Atlantic, down to and including the Spanish region, British region and up from Spain appear to be a little vulnerable atm. There seems to be a combination of 'energies' coming from the west/NW of Spain and neighbours - and from the east (Mediterranean).

The Mediterranean (and across to Turkey) will continue to rumble, and I feel there may be sporadic moderate quakes there - from M3 to a 'maybe M5.

Australia had mini run of tremors, ranging from smaller to an M3.5+ in lower WA. The most active regions in OZ in the last month have been SW of WA, SE of NSW/bordering with Vic and Victoria (SE and E). I will put up a "last 30 days" of OZ pic later.

NZ continues to rumble with tremors/quakes, some registering as weak on the 'felt' scale (GEONET). Cook Strait has had an M4'ish and I feel that this region (including Seddon which is still experiencing several tremors each day) may produce a couple more moderate tremors/EQ's soon.

More later folks,
for now, Duck.

If you follow the USGS earthquake site registers, you will now see on their site - this message -
Quote:
Due to a lapse in Federal funding, the USGS Earthquake Hazards Program has suspended most of its operations. While the USGS will continue to monitor and report on earthquake activity, the accuracy or timeliness of some earthquake information products, as well as the availability or functionality of some web pages, could be affected by our reduced level of operation.
- USGS

Though they have placed this message on their site, the USGS seems to be still be effective and timely in noting many EQ's/tremors as they occur.

There are several other agencies whose earthquake notations are contributed to the Global Incident Map - Earthquakes

Apart from the above Map, there are other agencies around the globe, who register many other tremors for their respective regions which don't show on the Map.

Those links mentioned in my 'signature' below and,
RSOE EDIS - include EQ's

Japan Meteorological Agency

Icelandic Met Office

British Geological Survey

...just to name a few.

The Gulf of California has come up with an M4.3. This quake is located on the plate edge/'fault' which runs north, through and past Los Angeles and San Diego - slightly to the east. Many of the tremors around these two regions seem to be associated with this plate edge/'fault'. Other small tremors have occurred along this 'fault' all the way up to and including the west of Eureka, California in the north. So, this plate/'fault', though it is not unusual to see tremors along its stretch, seems to be renewing energy in some spots (e.g. the Gulf of C.) at the moment.

Anyway for the moment, Duck.

Re: Earthquakes - 03/10/2013 18:40

So many moderate tremors/quakes today....
Sikkim, India had an M5.3, very shallow at 2kms deep. Has caused panic in the community and buildings to have cracked in many places. Note this is so close to the Himalayas, where I had an irking feeling that larger/moderate movements were going to occur along the vast spread of the Himalayas.
For reports from some folks there, see here.

France has been rattled by a series of tremors/quakes, the largest so far an M4.9. Last night I had a feeling that France may have some 'issues' today - for some reason the letter "J" for Jeune, Jersey (near NW coast) was sticking with me for a moderate quake. These movements are reminiscent of my feelings of those 'energies' I mentioned previously, emanating from the west and the east.

The Owen Fracture Zone, SE of Yemen, is still active (M4.8 today) and this region (again, the upper part of the Indian Ocean/Arabian Sea) is one which I suspected would keep producing M5's (+'s). Maybe the south of Pakistan and perhaps towards Djibouti and/or Eritrea (leading into the Red Sea) may see some corresponding movements (?).

The western side of the Pacific has been active still with M4+'s, as has Indonesia - north of Australia - and to the NW of OZ (Indonesia). This whole general region may continue to crop up with more M5's.
NZ is still feeling small to the odd moderate quake/tremor, and this will continue. White Island is also active. The major plate/fault running through NZ will continue to throw up tremors and the odd M4+ in the near term. I get a gut feeling that this plate may produce a moderate quake, perhaps in the Cook Strait and/or north of the North Island.

Africa - Zambia came up with a moderately surprising EQ. I have been suspecting that Tanzania/DR Congo may have come up with a movement (there is a volcano in this region).

I get a feeling that Puerto Rico may come up with a moderate tremor/EQ soon. Maybe too, near Barbados/Trinidad & Tobago, perhaps a less than moderate movement.

Central America may continue to experience tremors down the coast.

The Gulf of Alaska may yet come up with a moderate quake.

Will continue this post a little later...have to dash.

For the moment, Duck.

Re: Earthquakes - 03/10/2013 22:22

For those of you who have followed my posts, you will remember that I have had a fairly constant feeling that that vast Mediterranean region, from Turkey over to Italy, and further over into Europe, Spain and curving up through the northern countries (France, Poland etc..) was going to (and has) keep/kept catching my focus for increasing and ongoing movements.
Just in the last 24 hours or so, the number of moderate tremors (M3 and 'up' in size) have been in line with my general suspicions for this vast region.
I still feel there is an inter-relation between most of the quakes, in regards to the core of their cause, especially from the east of Spain and all the way over to/including Turkey. Pakistan (also to the south and SW of) I somewhat add to this whole equation. Maybe even the activity in the Owen Fracture Zone (SE of Yemen) and other nearby activity, could be related.

Generally speaking, the greater intensity of 'tremor' activity has been in the above-mentioned regions today. The other 'region' which has produced substantial movements in mostly 'single' moderately sized bursts, is Asia (Japan, Indonesia, China, China/India border, Philippines...+ some of the Pacific Islands).

The U.S. regions I also watch have just slightly de-energized, but this may not be for long...the tremor activity may pick up a little there from now'ish, maybe once the first mentioned regions (Mediteranian etc..) settle somewhat (?)

All of the above are amateur and unscientific feelings. (I know I sound like a broken record, but I like to mention this occasionally..a bit like a disclaimer if you will wink )

For now, Duck.

Re: Earthquakes - 04/10/2013 18:14

If I am correct, I think SA, near Hawker/Arkaroola may have just had an M2+. Nothing is showing up on any EQ maps, but I'll hedge my bets that this may have just occurred.....

More later, Duck.

Re: Earthquakes - 04/10/2013 18:31

Just as I suspected, near Hawker has had an M2.4 at 1km deep.
About 5 minutes after my last post, Geoscience put this tremor up on their site.
I have been anticipating movements in this general region over the last couple of days, using the 'cloud' on the satellite as a guide and the consistent mini pre-movements on a seismograph.

Re: Earthquakes - 04/10/2013 21:16

Another short post for today...

South of Timor's M5.2 at 10kms deep (40 minutes ago) was a double movement. There was the initial moderate quake, then a subsequent one of approx the same size a few minutes (about 5) later. Therefore 2 quakes in quick succession; this probably was double movement of the same plate shift (same spot).

Sorry for the short posts today, but I am in and out of the house every 5 minutes (or so it seems)...

There is a buoy SE of Tasmania/SW of the South Island of NZ in event mode. There appears to be a drop/variation in depth/then corresponding rise of 200 metres. The reading is water column depth - this doesn't mean a tsunami necessarily, but more than likely the buoy has read an increase in the distance between the buoy and the sea floor - if I am correct????? I am still learning about these readings, so have a look for yourself at the link below;

Re: Earthquakes - 05/10/2013 10:38

Here's an interesting article on "The Watchers" website regarding the seismic activity in Romania currently. Seismologists and locals alike, are somewhat confused about the earthquake swarms, the sulfur smells, cracks in the ground and so on....see here -
"Mysterious earthquake swarm and big earth cracks reported in Galati, Eastern Romania"

Here's a webpage from the National Institute For Earth Physics - Romania Romanian Seismicity

Below is a snapshot of the European/Mediterranean region (today/now), showing one of the tremors in Romania and how this general region (as shown on the map snippet) is being rattled by tremors/quakes till now. I personally feel that the movements in this vast region may be interrelated [as I've mentioned previously] and Romania's faults may be responding to such. The sulfuric smell and "boiling water gurgling sound" is curious and I wonder if it is related to what has been going on in that vast region from the east of Spain all the way over to Pakistan..??? Just an amateur thought folks (with no scientific conclusion or proof in this idea on my behalf).

map snippet courtesy of Global Incident Map and image uploaded with ImageShack

If you have a look at the first map in this article from Live Science - "New European Earthquake Catalog Offers Clues to Future Risks" there is a black line representing a "first order fault" running through/near Romania's current tremor location.

The Gulf of California is experiencing moderate quakes, as I felt it may, and the general coastline of California (U.S.) is starting up with regular tremors, again, as I also felt it would in the current time.

There was a doozy of an M6.4 on the Mid-Indian Rodge today., which may lend us to seeing some more movements in the Indian Ocean in the short term.

The waterway between Quebec and Rimouski (Canada) came up with another tremor. This has also been a region which I suspected would possibly come up with some tremors too.

As usual, there is so much more I could gabble on about here and so many other locations which could be mentioned, but I don't want to overdo posting here, so,

For the moment, Duck.

Re: Earthquakes - 06/10/2013 00:25

Maybe this is not unusual, as I haven't followed this EQ map for very long, but there have been 6 quarry blasts registering tremors from approx M1.5 to M2.3 in the U.S. and one in Canada (all near the west coast), within a time frame of about a couple of hours in the morning time (US time). Several were in rather close succession; a couple near minor fault lines and one in a port region.

Locations are;
M2.3 near Princeton, Canada;
M1.5 Port Ludlow (between 2 fault zones), Washington;
M2.2 near Dayton, Oregon (Mount Angel Fault);
M1.7 near Philomath, Oregon;
M1.2 near Springfield, Oregon;
M1.6 near Shady Grove (near the Sky Lakes fault zone), Oregon'

The above-mentioned fault zones appear to be noted on the USGS map as minor faults.

I don't think I can see anymore on the USGS Map

This post is just for information's sake and as a matter of interest (I just thought it was curious). I haven't seen that many diamonds (designated blasts/recording tremors) in the shortish time I have observed this map.

Re: Earthquakes - 07/10/2013 10:26

Didn't get a chance to jot any more notes after yesterdays' post.

Interestingly, west of Macquarie Island (south of Australia/SSW of Tasmania) came up with an M4.7 (10kms deep) 5 hours ago.
From this region and directly north running from here, there is a trench/fault which leads up almost to the southeastern corner of South Australia/SW corner of Victoria. This 'line' intersects east/west running 'faults' west of Tasmania, and which all point to the far SW corner of Tassie.

South Australia and Vic (haven't checked other states yet) are experiencing small intermittent movements, and I get a feeling that Geoscience may even put a couple of tremors up on their site for S.A., maybe near Canberra, W.A., and an outside chance for Vic (though, the movement I suspected may not have been decent enough to register/warrant a formal notation).

As I suspected, the west coast of the U.S. Eureka down - and particularly near L.A., revved up again with a few more M2+'s than we have seen in clusters for a little while. I feel there was energy heading north from Baja California/Gulf of California up into/influencing this region.
Canada has had a couple of coastal jiggles/movements following on from California.

Mexico is another general region I felt would come up with M5's, as with the Chile region and offshore. I meant to mention previously that west of Los Angeles (Chile), offshore may come up with some moderate movements too...this has occurred, but I didn't get time to jot this yesterday.
This may (or may not) lead to another movement closer to shore between Santiago (Chile) and Los Angeles (Chile).

The words Galapagos, 'rocky', loch, san-, atoll, ridge, laken, Santa/Saint, green and bay have all stuck with me over the last couple of days for some reason....may mean nothing.

There are three buoys in event mode currently.
That one SE of Tasmania/SW of NZ Sth. Island is showing 'stable' readings (level) but is still 'flashing' on the NDBC site
There is one NNE of Dampier, Australia/south of Indonesia, showing 'event mode', as is the buoy in the Bay of Bengal (interesting movement there).

The Mariana's M6 today at 127kms deep, and a couple of others in the west of the Pacific, has me feeling that there may be more movements near Japan, north of PNG, maybe towards Ternate/Moluccas region - Indonesia, or near Davao (Philippines). Not predictions, just feelings.
Fiji, Samoa and some other Pacific Island regions, may also (but not all) come up with the odd M4 (+?).

Back a little later...Duck.

post note; no sooner had I finished the above notes, Santa Cruz Island has just registered on the USGS site with an M5.

Posted by: duckweather

Re: Earthquakes - 08/10/2013 11:00

Hi folks.

I feel that near Canberra today (about 2 hours ago) has had an M2. Nothing has come up on the Geoscience website so far, or for the last 4 days actually confused
Will see what is noted for WA, SA, NSW at some point.

Yesterday in noted;
Quote:
The words Galapagos, 'rocky', loch, san-, atoll, ridge, laken, Santa/Saint, green and bay have all stuck with me over the last couple of days for some reason....may mean nothing.


...and San Francisco (-san, bay), Scotland (loch), Santa Cruz Islands (Santa/Saint) coincidentally came up with quakes/tremors....and laken, 'rocky' also were relevant to other locations' tremors. Sometimes out-of-the-blue I get words like this sticking with me for some reason. This has happened on several occasions and sometimes they are poignant and other times they mean nothing.
So far 'Galapagos' hasn't been a relevant 'word' regarding the above.

Near Davao, Mindanao - Philippines came up with the M4+ I anticipated, as did Japan and some of the others in the west of the Pacific. PNG's M4+ was east, not north as I had anticipated.

New Zealand, South Island, had an M4.4, registered as strong by GEONET

14 hours ago. The general region near Seddon/Cook Strait is continuing to experience daily tremors. The fault running through all of NZ is still unsettled, and we may see another EQ south of the Sth. Island; to the north of the North Island and at some point in the near future (time-line? next couple of weeks???) perhaps near Cook Strait....feeling, not prediction.

The Mediterranean, Spain, Turkey, through to Pakistan/Arabian Sea, Bay of Bengal - general regions - are continuing to rattle occasionally. I feel that these regions may keep producing a majority of the smaller tremors to the west and maybe the east could produce less of the smaller and a couple of the moderate tremors/EQ's. The western end of the above mentioned regions may intermittently produce an M4(+?).

For the moment, Duck.

Ok, just checked the Geoscience website and they have just put up multiple registers of tremors for the last 4 days.

There is a reading on 2 international EQ recorders here of an M6.1 which has occurred in the northern Pacific region, SE of Japan (way at sea).

An M4.5 has just occurred off the east coast of America - see here for preliminary details.

Now, maybe I am just weary atm., but I could have sworn I felt a distinct deep vibration under the floor/underground.
Looking at this seimo set - here my feeling is telling me there has either been a large quake somewhere O.S. or the lower half of Oz is brewing for or had a deep grind/slight shift or something.....
I know that sounds a bit dippy, but that was a strange feeling....or i just need a headache tonic wink

Re: Earthquakes - 08/10/2013 19:02

Ok, maybe I should have downed the cat-worming pills instead of a headache tonic grin
The vibration I felt may have just been reverberations from the EQ of M4.6 in the Banda Sea....
I'm glad, actually, that it wasn't a big quake. They aren't very nice.
An obscure part of my thoughts (whatever cogs are still turning in my brain atm) is that I hope that vibration is not a sign of an M5+ EQ beyond now for the Banda Sea area or this general region....I am more than likely wrong anyways....

Daffy Duck.

Re: Earthquakes - 08/10/2013 19:39

Petros, you are too kind...cheers.

I am not always right though. Also, I can't cover every movement (EQ that is) that occurs because of other commitments. But when I sometimes notice or feel something (EQ that is, again smile ), I like to jot it here or in a diary, if I am home to do so.
I just hope you guys aren't getting sick of me sometimes, especially when I overdo my posting some days blush

Anyway, the only movements I wouldn't want to share my feelings on would be those if I grabbed those cat-worming pills instead of the h'ache tonic - what a cat-astrophy that would be....

Anyway folks, for now....Duck.

Re: Earthquakes - 08/10/2013 21:15

This was the strange feeling I have been getting tonight - the Banda Sea initial quake was not going to be the end of the strange vibration 'movement' I felt. It felt like there was more to this quake and that there was a greater shift happening in the Pacific....

Another Banda Sea quake (M4.5+) then,
Davao Philippines, M4.7 just then,
and straight after this;
the Central East Pacific Rise M4.4.

This may be a mini flurry of movement, and I hope I am wrong (probably am) that there may be more to come.
At first I felt that there may be a larger quake, but this may be actually panning out as a series of plate related quakes...will see...

Duck (sorry for the multiple posts tonight).

Re: Earthquakes - 09/10/2013 08:03

Just a quick note for now,

If you want to keep up with the EQ's in the Pacific and elsewhere, the Earthquake Report has quick updates of current quakes.
The Pacific is still rattling, with the lastest moderate quakes being PNG, Vanuatu, the Kuril Islands...to name a few.

Cheers, Duck.

Re: Earthquakes - 09/10/2013 15:53

There seems to have been another double movement earthquake/s, but I can't find anything on it at the moment, but I am guessing it was the Banda Sea, possibly an M4+....will see

Duck.

Re: Earthquakes - 09/10/2013 18:07

Well I'm tossed...I can't find anything on the movements I mentioned above (looked in most 'places' in the short time I have had today).
For some reason the number 9/13 or 9:13 or 9 and 13 (in whatever combo) is sticking with me today. And...as I always say, "this may mean nothing". (This may relate to Indonesia, or elsewhere...???)

Unless it has been a moderately quiet day on the EQ front or my computer has developed a 'personality', it appears that some of the EQ monitoring sites haven't recorded too many tremors.I suppose thankfully it has been a less EQ rattling day so far.
One site didn't record a tremor for 2 hours, which I thought was a little unusual.

The Oklahoma region has had a bit of an EQ swarm today.
Japan has registered several EQ's/tremors too.
The west coast of the U.S. has been rattling along with small tremors today.
Our seismo's are still showing the odd jitters/irritations, some of which are localized movements and others reverberations from distant quakes. I still feel that the south of the Oz continent (considering Macquarie Island movements) is not completely 'settled' yet.

Our neighbours in NZ are still feeling fairly consistent rattles on both islands. White Island may become an issue again.

For now folks,
Duck.

California has been enduring another tremor swarm in the last couple of hours.
The Middle East/Mediterranean regions may experience a couple of moderate tremors in the short term, i.e. some raised activity. An M4 has already come up in Iran and a couple of smaller tremors in Turkey.

The Pacific has not eased up much and continues to throw up a seemingly continuous M4+ here and there. For the moment, I can't shake off the feeling that a larger (moderate +) EQ may occur in a Pacific region. I may be wrong.

For the moment,

There was a paper published in 2009:

Hi cosmic (naz) and all.
I have no internet at home atm. I have called in to annoy a friend for 5 minutes just to jot this note smile
Not sure when I will be adding more bits and pieces here, hopefully soon.
Cheers for now,
Duck.

Re: Earthquakes - 10/10/2013 20:45

Finally got this internet of mine to work (hope it doesn't crash as I type this... crazy )

Anyway, Cosmic (naz), The avenues of consideration and thought regarding the cause, signal and even possible prediction of earthquakes is expanding. Some sectors of science are skeptical of some other sectors of scientific thought and/or study and/or observations.

What I feel would be the ideal, would be for a collaborative consideration and gathering of all ideas (even those considered left-of-centre - like cloud effects theorists) and application of all related sciences (e.g. understanding of electrical, hydro-, thermal, geo-, physics, solar, lunar, chemistry and so on) to perceive how all or many of these elements/areas may interrelate, co-effect, contradict, annul, unify, influence (and so on) each other in parts or as a whole - regarding earth/geo activity.

I have always believed that 'nature' and its' behaviours in various forms are or can be effective of the other.
As an axample, if you remove an element in nature, let's say water from a water table, then the compensation for nature might be in the form of a land collapse? -> earthquakes/tremors?

There are several known causes of earthquakes, as well as possible precursors. Marrying the science, hypotheses, observations surrounding such, I believe will serve to benefit us all. Though Mother Nature can be mysterious at times, I feel that future scientific knowledge may unite the many ideas for a collective understanding and reasoning as to a fuller understanding of the dynamics of this beautiful planet of ours.

Just revisiting some observations of my own after the Lilydale 'explosive' tremor this year, I observed several vertical clouds immediately in the hour after the tremor.
My belief is that these were vapor expulsions at various points along a fault line.
'Ribbed clouds' also observed at other times, I feel were signs of geo-electrical emissions given off by the agitation of a fault line (underground friction). I am not sure about this, but this could also (the spaces between the clouds) be heat streams being emitted from this agitation.

Now...I must mention here (yet again) that these are not scientific conclusions on my behalf...I am not a scientist. They are just feelings or suspicions only.

Anyway, I hope I made sense with the above jottings...I could bore you for hours with my thoughts on this stuff grin

Got a wee feeling that the NW and SE of the Pacific may 'act' up with moderate+ EQ's.
I have already mentioned that I feel that from the Mediterranean over to near Pakistan may increase activity, and Turkey has just had a mini cluster of small tremors. When I see clusters, I feel there may be signs of fault irritations (maybe associated with volcanic activity in some regions ?????) gearing up for a more moderate movement.

I won't gabble on any more for now. I may have already put you all to sleep by now blush

Cheers, Duck.

Re: Earthquakes - 11/10/2013 10:54

Being one (a nerd) for interesting curiosities, on the Earthquake Report site - for October 9 , there was an interesting report from a person in Key Largo, Florida, regarding his/her observation of "long sets of swells" (after an M4 in the waters of the east coast??) as they ventured out to sea in a boat. They felt it was unusual and these swells just may have been a repercussion of the EQ on that day.

Kamchatka has been quite active (volcano related) and I'm wondering if my suspicions of a potential larger moderate EQ may emanate from this region or somewhere along the north or NW of the Pacific...?

For the moment,
Duck.

Re: Earthquakes - 11/10/2013 20:54

A few areas which may come up with tremors/EQ’s could be;
SW of Eureka/NW of San Francisco – offshore/coast (and inland slightly east in the mountain ranges near the border with Nevada)
Halfway between the NW coast of Australia and SW of Bali – at sea
SW off the coast/at sea of the Sth. Island off NZ
Some others I'll note later if I get time.

There has been a noticeable uptick in the number of moderate quakes in the Pacific and elsewhere today.
After somewhat of a lull in these larger tremors, a cycle of M4+’s has renewed today, with Pakistan coming back into the picture –maybe more activity to come in this region.
Although many regions, - the U.S. west coast (including Yellowstone); Mediterranean; Middle East ; Pacific edges have all been active, instead of seeing a region or two being active, then another at an alternate time.

The NW and north of the Pacific and SE (South America) has become active, also as I felt it may.

Puerto Rico (or surrounding region)is still a region which I'm still feeling may come up with a moderate EQ.

For the moment, Duck.

Post note;
After I had finished typing this in Word, the California tremor of M3.4 in the ranges east of San Francisco (near the border with Nevada)came up, which I had a gut feeling it would.

Re: Earthquakes - 12/10/2013 08:50

Our neighbours in New Zealand have had several moderate tremors today - an M5.4 (NE tip of North island), and strongly felt M4.8 and M4.6 also in the North Island near the east coast (on land). Unfortunately, I feel there may be a few more to come in the short term.
See GEONET here

Brittany/NW France has also experienced an M4+ and another lesser tremor, which is near Jersey (remember I mentioned that word "Jersey" as one which was standing out to me in my mind a couple of days ago?).
See here - for reports/comments from France (mostly in French)

California has been, and will be, quite active in bursts too.
I am really only repeating myself when I say that the Pacific plate (and associated volcanoes) is not in a very good mood at the moment. Many M4+'s to be seen and felt currently.

Indonesia, NW of the Australian continent, began serving up M5+'s again and another may occur in the region I mentioned in my last post (way SE of Bali?).

Anyway folks, for the moment,
Duck.

Post note; no sooner had I finished typing the above and posting, the Kermadecs have come up with a "severe" M6.3.

Posted by: duckweather

Re: Earthquakes - 12/10/2013 10:41

An M5 has occurred WNW of Eureka, California at 10->15kms deep.
There is no tsunami warning issued and this is just north of the region I refer to a fair bit for the possibility of a moderate EQ.
The fault this quake appears to be associated with is the Cascadia Fault line (described on the USGS site as the "Cascadia megathrust' fault zone.
This fault zone continues northward and 'parallel' to the Canadian coast. Having said this, I get a wee feeling that this quake may influence movement up the Cascadia (Canada).
There will be and are aftershocks happening near Eureka, which are dwindling in size, but one a little bigger than the little ones may follow on (in the mix of aftershocks).

See here for comments from the folks in California regarding their experience of these quakes.
The M5 involved 2 movements - the first was a shifting/grinding movement, then the second was the movement that let loose the M5.

More soon,
Duck.

Re: Earthquakes - 13/10/2013 01:35

I've had an unfortunate sneaking suspicion for a while now that the Mediterranean region (towards Greece/Turkey west) was going to experience a sizable EQ and they (Crete)have just had an M6.4, quite shallow.
USGS info
Earthquake Report info and community responses/comments
Don't know what damage has been caused yet or injury to the folks in this region.

Another region I had mentioned that I was keeping an 'eye on' was Puerto Rico "or a surrounding region". This too came up with an M6 (offshore Venezuela) today.

Crete will endure aftershocks. This EQ occurred near a fault/plate edge which runs from Pakistan, all the way through Iran, Iraq, Turkey then west past Crete.
Let's hope no-one in the above quake regions has been poorly affected, though I am guessing there will be/have been water/sea disturbances in these areas.

For now, Duck.

Re: Earthquakes - 13/10/2013 11:24

Good morning folks.

Well what an interesting last 24 hours or less it has been. There have been many M4+'s, and up, dotted around the globe. It almost seemed like a ping-pong effect. I would guess that there was a 'generalized' shifting/movement in many of the plates, instead of sectional behaviour - i.e. localized (in a couple of places) versus a global agitation.

In Crete, there were reports of the movement lasting up to nearly a minute of shaking/rolling/wave-like motion, which is an unnerving amount of time and a considerable unsettledness of plate behaviour.
A couple of people even described a strong gust of wind preceding the EQ, which I thought was curious.
One older lady injured herself trying to jump out of a window and supermarkets had their shelves rattled sharply, knocking supplies on the floor. Luckily it seems that no-one was killed and structures managed to stand the movement. The aftereffect of the quake left many people feeling sick, some disorientated momentarily and others dizzy. The sway/boat-like movement that several folks felt, left them feeling sea-sick.

The initial "P" waves associated with the production of a quake can make you feel like your equilibrium is 'off' and can have the effect of feeling you have moved side-ways (even if the subsequent "S" wave movement does move the ground sideways). This can be very disorientating and can leave some feeling like they need to gather/right their equilibrium again. It can also sometimes feel like sea-sickness, dizziness and maybe even induce nausea in some....

Some folks in California's M5 yesterday, described the feeling of being lifted up during their EQ.

Luckily it appears with all of the EQ's so far that the movements haven't created disasters for related communities.

For the moment, Duck.

Re: Earthquakes - 13/10/2013 20:21

Hi folks.

A great majority of the quakes (predominantly M5 and +) have been along plate edges. Generally speaking also, the smaller quakes have been mostly along faults.

The folks in Fiji definitely felt the M5.1 near Suva in Fiji. Some reported fears of a tsunami being generated, feeling side to side sway and rattles.

Iceland's M4.8 and a follow on tremor/s have also rattled locals there.

The number of M5's (and +'s) has been quite incredible in the last couple of days. I would imagine that there is not a nook on the planet that hasn't felt at least a vibration of any degree from these quakes. I sometimes wonder what the sea-life and land creatures 'feel' when all this sort of movement goes on. I wonder what it does too, for example, the sonar sensitivities of many sea creatures.

Also, I'd be fascinated to see an computer representation of any electrical (etc.) activity given off by (from the earth's surface and below) all of this activity...if any of you know of such a program, can you point me in that direction, unless I find one on the net in the meantime...

For the moment (gotta cut a birthday cake for an excited birthday boy) smile ,
Cheers for now, Duck.

Below is the current "last 7 days" image of Australia and surrounding regions - image uploaded with ImageShack and the pic snippet courtesy of Geoscience.



Macquarie Islands' quakes date from the 9th October (yellow circle) to today's EQ (red circle). Notice how the 'energy' had traveled north or this latest EQ may be an indicator of some generalized/intermittent instability (by degrees) of the plates/trenches in this region. Pressure coming from the east and/or south (Antarctic) ??? Could be wrong here.
I'm not implying a disaster scenario here, but I wonder if another tremor (smaller?) may occur towards Tasmania (SW? ish) or a moderate one perhaps central/south or SSW of the Australian continent?? Will see.

The above map doesn't show New Zealand's many EQ/tremors.

For now, busy Duck.

Re: Earthquakes - 14/10/2013 16:14

Central and southern California are off and running with tremor clusters again. A few folks there may be feeling that "not again" given their recent experience of a cluster, then an M5 off the coast of Eureka. Hopefully this is just a minor 'adjustment' and not a build up to a moderate quake. Interestingly, though, Mount St. Helens came up with a small tremor.
Hawaii has been feeling small semi-regular tremors too, corresponding with movements in California - this may just be a coincidence.

Northern California near Eureka, has been sneaking up with small movements during South and Central California's tremor cluster.
There may be an M3 (+? or ++?) to come for the Cali region.

For the moment, Duck.
Posted by: duckweather

Re: Earthquakes - 14/10/2013 18:45

3rd post for today blush

Anyways, I have had a closer look at where the bulk of the California clustering is in the south. It appears that there is a concentration of continuous small tremors occurring in the Salton Sea, NNW of Brawley. A couple of years ago (and perhaps at a time I haven't looked into yet) Brawley had a moderate EQ, which displayed movement which was 'sliding' side-to-side in motion, as well as the associated rumble. This EQ was an M4+.

Running up from the south towards Brawley is the Imperial Fault (quite sizable) and from the Salton Sea -> NW, is the San Andreas Fault. There are other 'minor' fault lines scattered in this general region, but the current tremors seem to be a the conjoining 'sections' of the two larger faults mentioned above.
A couple of other tremors have occurred to the west of this region, inland from the coast.

Global Incident Map - Earthquakes
Have a look at the list of tremors the Salton Sea region is experiencing (showing as "Southern California" on the Global Map).

For now, Duck.

Re: Earthquakes - 14/10/2013 23:20

As I type this note, there is somewhat of a lull in general EQ activity, except for the odd small tremors and the Gulf of Aden M4.7 and Indonesia, Sulawesi M4.8...which is a good thing. But I don't think the 'quiet' will last for too long unfortunately.

I'm a bit distracted at the moment, as my pair of budgies clutch of eggs have started to hatch. I'm going to be a granny grin Well....sort of...

Re: Earthquakes - 15/10/2013 12:23

I had an awful feeling over the last few days that a major quake could hit the west or NW of the Pacific. I couldn't shake it iff.

USGS event log

Earthquake Report - indepth report

This was a very nasty quake with some serious ramifications.
My thoughts to those poorly affected and/or lost their lives with this EQ.

Some of the aftershocks are also going to be quite sizable and will add to the problems there.

Just an additional note; the geomagnetic absorption from the solar issues (Mclass Flare etc.) was focused on the Pacific, tending (edging)towards Australia east coast and Pacific region to the north, NE, and east of Australia.

For the moment, Duck.

Re: Earthquakes - 15/10/2013 21:41

What an horrendous day for the folks in the Philippines. The landslides, seemingly constant movements, house/building collapses, sadly - fatalities of 28 and 150+ injured, and a small tsunami.
Many folks felt sick, dizzy or disorientated by the powerful effect of the shock-waves and movements associated with these movements. Many folks, for some time to come, will be feeling very jumpy and possibly anxious - perhaps for fear of the ground moving again. Some will feel the effects of PTSD. And, obviously, some will be grieving for those folks they have lost. It will take some time for all to regain a sense of peace again.
This could be a similar situation to the after effects of, for example, the large quakes in Christchurch, Japan, Chile and so on.

Did you notice how the western side and coast of the U.S. (including near Yellowstone) appeared to be triggered into tremoring, including M3+'s, after the M7+ on the opposite side of the Pacific? Now, this could have been a response of sorts or even obscurely (and only in my mind's thought) the pull on the west coast, or agitation, which was all that was needed in that moment to set the U.S. west off with tremors again. Or, there may have been an energy simultaneously affecting the east and west of the Pacific.

I wonder if today's large quake and ongoing aftershocks may 'upset' the recent moderate EQ locations in, for example, Indonesia, Banda Sea, Taiwan, Japan, PNG and maybe as far as the Mariana's.....maybe wrong though.

For some reason I keep getting drawn to the North of NZ (away from the North Island) and down (south) for a moderate (or +) EQ. Water/sea is the main feeling persisting here....and, yet again, I say this is (and all my suspicions/thoughts are) just a feeling and certainly not a prediction.

Alaska has, similarly to the west U.S. coastal region, experienced 'extra' tremors after the M7+ too.

For the moment, Duck.

Re: Earthquakes - 16/10/2013 19:31

Hi Nerd65.
It is sad to see familiar and interesting places (including those visited) destroyed or so badly damaged. Let alone remembering the people you meet there and now knowing that they have endured this horrible situation.
The Earthquake Report - still updating with new info on the Philippines EQ's, shares some video and pictures of some of the damage there. Sadly approximately 107 folks have lost their lives, but authorities feel this number may rise as they continue to search through the rubble and landslide locations.
The aftershocks are still occurring, and I felt they may, they are still of a considerable size - similar to what Christchurch experienced.

The west of the U.S. and the Mediterranean->Pakistan have experienced slightly increased activity too.
As I also felt may occur, are the EQ's dotted along the countries north, NW and NE of the Australian continent.

Also I meant to say "electro-magnetic" instead of "geo-magnetic" in a previous post.

For now,
Duck.

Re: Earthquakes - 16/10/2013 21:49

The Solomon Islands has just had an M6.7 at 10kms deep (preliminary).
Did anyone else feel the ground vibration just before this occurred??? When we felt it here, I said to the kids (x4 teens) that something is going to give any minute - meaning a large quake. And, just checking Earthquake Report (quick notifications) there was the quake in the Solomons.

More info as it comes in.

Keep an eye on the Earthquake Report here

For the moment, Duck.

Update - M7.1
2nd update - also being pinned as PNG (see the Earthquake Report link above)
Posted by: duckweather

Re: Earthquakes - 17/10/2013 08:48

Good morning folks.

There is still little info coming out, so far, on PNG's large EQ.
Now that it is daylight, more should come to light as to any adverse impact on the communities there and any reports from the locals there. I would actually find it hard to believe that nothing was affected by this large quake.
Aftershocks are more spaced (time-wise) than the Philippines quakes - due to the differences in activity, nature of movement etc..
I do feel, though, that there were water disturbances, perhaps a higher tide/waves affecting the island surrounds - maybe not to inundation level, but noticeable agitation.

Another location/region which I felt my come up with a moderate EQ is south of the South Island of New Zealand - which has done so this morning (our time) with an M5.2, WSW of Invercargill - off the coast.

The large movements in the Philippines and PNG, I feel display some 'angry' movement in the Pacific plate (generally speaking). I also feel that because of the close timing of these two quakes, there may be some more movements, maybe of a bit of a smaller nature till all is more settled.

I'm sorry to say that I knew there was going to be another M7 yesterday to the east of the Philippines (in another region). But, I don't like to make grand statements regarding these feelings, as I think that would/could be irresponsible of me and if I was wrong, I could unnecessarily panic and upset people. So sometimes my jottings here are just general or sometimes a little cautiously cryptic.

Anyway, there may be more M5's to crop up in the Pacific regions.
The Mediterranean may feel an M3+(+?)
Maybe near the Arabian Sea....
Over to Spain and France, for example, may feel a couple of M2(+'s).


For now, Duck.

Hi folks.
For my first post today, I thought I would like to mention how my thoughts and prayers are with our fellow Aussies who are enduring the terrible fires in NSW.
Having been associated in various ways with the Black Saturday and Ash Wednesday and Ferntree Gully Fires in the past, I understand how traumatic these terrible fires can be.
Thank goodness there appears that no one has lost their lives. But to see your home burn to the ground and livelihoods lost is just awful for those folks.

I will post on EQ's a little later.

Re: Earthquakes - 18/10/2013 13:26

Here's an interesting article on The Watchers website about a potential newly discovered fault line which may have been the cause of the Philippines large quake.

"Newly discovered fault line may have been source of M 7.2 Bohol earthquake"

My feeling about this situation is this;
The pressures emanating from the Pacific Plate to the east'ish and the presuures from the Australian Plate from the south, and just maybe pressures from the SW - Indian Ocean, have possibly combined to put a 'squeeze' on this general region. Similar to if you put 2 fingers on either side on the top of the other hand and gently push 'in' (from sides inward), you will see the skin creasing with the pressure of being pushed. (My non scientific opinion only). But given that the 'objects' being possibly pushed/pressured in this fashion are actually earth's plate edges (and associated structure), these more solid objects are going to experience less fluidity/flexibility (maybe) than the skin on your hand, and the outcome may be more destructive and solidly felt by varying degrees.

I also feel that there was an existing 'weak spot' in the area of the large quake, which gave way under the strain of the pressures endured. Equally, I feel there are many more of these sorts of characters (undiscovered faults/potential weak spots) around the world, who given enough of a 'shove' could produce future earth movements - where maybe least expected.

The energy in the Pacific, I feel has dissipated a little, for the moment (though M4+'s may still pop up here and there) and the Mediterranean, Atlantic, Indian Ocean, Middle East general regions may be the focus of some raised activity (number of tremors/quakes - not necessarily on the scale of the Philippines and PNG quakes).

The west coast of America, South America and maybe Central America may continue to jitter with;
* smaller M1=s, M2's + M3's (maybe M3+) U.S. coast/inland
* M3+ and maybe an M4+ ('s) - Central America
* M2+'s, M3+ and maybe the odd M4+ - South America

I also meant to mention that New Zealand is continuing to experience M2's, M3's and the odd M4+'s. This may continue, but I feel there may be a moderate quake to come - this maybe White Island or further down the plate edges...

For the moment, Duck.

Posted by: duckweather

Re: Earthquakes - 19/10/2013 12:47

Hi folks.

A couple of buoys have shown or are showing interesting jittery readings.
The first one I suspected, because of it's jitters, may be a potential for a series of quakes, was the one below Pakistan. Since I noticed this buoy's behaviour several quakes have registered in Pakistan and even north of these EQ's in Afghanistan and through to lower west China (involving the west of the Himalayas).

The second buoy catching my attention now and in previous days is the "Tasman Sea 2" bouy, just west of the lowest tip of the South Island of New Zealand. A general observation (of mine) is that this may be an indicator (as well as my feeling of 'pressure' occurring there) that there may be more movements to come in this region (between the lower east coast of Oz and New Zealand).

Here is the link for the National Data Buoy Centre to see the buoys I have mentioned above.

All around the Pacific Plate edges came up with many tremors/quakes in the last 24 hours - not long after a lull, which was after the M7's prior to that.
It almost seemed like after the big quakes 'relieved' the tension build - then a lull - then reverberations spread across the Pacific, jiggling vulnerable spots around the Pacific. Or possibly the effect of the big quakes in the west, effected a slight 'pull' in some spots and/or allowed freer movement to occur in other spots. (Just a feeling, non scientific and maybe completely wrong here).

As I felt, region surrounding Spain has felt some EQ's/tremors, the Mediterranean (quite predictable atm), Middle East, Yellowstone, west of Eureka U.S. west coast, New Zealand etc..including parts of the Atlantic, Indian and Pacific Oceans.

Britain may experience a small tremor or two soon and I keep getting drawn to the sea off the east coast of America. Africa, lower east central, is also sticking with me for the moment. May mean nothing As does the Bay of Bengal and near Sumatra.

I have a feeling that Hawker (or general region) in South Australia had an M3'ish (maybe 2 tremors) last night/evening. Will wait to see if Geoscience puts anything up on their site.

Puerto Rico is still feeling small tremors with the odd M3. I still get a wee feeling that this general region (maybe a neighboring island) may come up with an M3+ (maybe an M4+).

For the moment, Duck.

Now here's a strange thing...
I just woke up half an hour ago and couldn't get back to sleep. So went outside on my decking. Had the word "California" stuck in my dippy Duck head; came back inside - turned on laptop and discovered that the Gulf Of California has experienced an M6.8.
Now, don't know much about how this large quake has impacted the communities in this Mexico region, and I hope not adversely.
Earthquake Report for more updating info
USGS records

For now, Duck.

Hi Duck,

California has had a few big ol' Oarfish (or ribbon fish if you prefer) wash up on its shores of late.

http://www.news.com.au/technology/sci-te...b-1226743256041

Which in turn got me thinking about the relation between big quakes & animal behavior. Apparently the Japanese and Taiwanese people view the appearance of the oarfish as an omen / harbinger of an impending quake. I highly doubt science will back this up however it's interesting to say the least.

Re: Earthquakes - 20/10/2013 10:37

Well after an 'interesting' night, the Gulf of California has come up with a moderate quake as an aftershock (I feel is a continuation of the movement there).
The initial large quake and the subsequent M4+ seems to be related to the San Andreas Fault system.
This has got many folks in the U.S. a bit on edge regarding a possible flow-on energy traveling up north through to the U.S. west coast. Looking at the 'design' of the fault edges from Mexico through to the far northern parts of the U.S., within the Mexico region itself, the fault zig-zags up until it gets up to near the border below San Diego. Perhaps because of this configuration, the substantial energy/movement that triggered the Mexico quake may have been 'absorbed' (for want of a better word) along these zig-zags.
But this doesn't mean that the movement/energy hasn't reached or could still impact the west coast, maybe in the form of M7's, but lesser M's (maybe up to M5'ish) in the short term.

The general Pacific region is still rather a hot-bed of movement at the moment, all around the 'perimeter' is still producing M5's and it appears that because of the continuing odd large EQ, that we may see the instability continue for some time.

Several of the Pacific Ridges/trenches etc., may also respond to this agitation. The central-east Pacific Rise has already responded with an M4+.

As I mentioned in a previous post, I 'felt' (feeling only, not factual opinion/knowledge) that there was a 'pull' on the eastern side of the Pacific (the America's) following the large quakes in the west of the Pacific. Because of this, and as I mentioned in my last post, "California" stuck in my mind and I kept getting drawn to the Central American coasts.
The nature of the San Andreas in Mexico and up is that the western side travels north, whilst the eastern side of it tends 'south'. So logically you would think that Mexico's fault line just went north/south, and you would probably be right. But, I still reckon that what went on (and still is) in the west of the Pacific effected the east.....

New Zealand is still rattling with quite a number of daily M2's, M3's and the odd M4's and M4+'s. I get a wee feeling that there may still be a more moderate quake near the Kermadecs/White Island and an outside chance further south (probably off shore).....??

As I mentioned Yellowstone is one region to watch for potential M3's etc...

For now, distracted Duck.

Ah Ms Milo, I observed that too.
When I heard about these amazing creatures come in to the surface from the deep, I thought, "Oh, oh..." not a good sign. Something is wrong for these not usually seen creatures escaping 'something' from so far down in the ocean.
Animals/sea life/birds are such important indicators of what is happening in their respective environments. Unusual behaviour is a sign of change - whatever that entails.

We humans should take notice of these kinds of behaviour, whether it be frogs surfacing from underground and crowding guttering in the Middle East; unusual sea life behaviour; bird distress or unusual migration; sea-life strandings (some); strange animal deaths and so on....

I'm always seemingly banging on about particularly clouds; sometimes wildlife behaviour; sea and buoy disturbances and a few other things, but I find these important gauges of change and sometimes warning signals....which sometimes with our busy lives, many may miss.

Cheers to you sis wink

Fiji just had an M4.7 at a very deep 534kms.
Can still see in a cup of water the reverberations from this quake and realized 'something' was filtering through the ground when I heard a very faint grumble - then checked the water in cup - then checked the EQ maps.

Interestingly, Geoscience for the Australian region only has only registered one tremor (NT M3.4 0n 15th October) for OZ.... confused I reckon there has been more.

For now, on a lazy warm afternoon, Duck.

Re: Earthquakes - 21/10/2013 12:47

Hi folks.

Well I wasn't imagining things when I felt there had been some tremors in Oz. And, I think another has just registered on the Arkaroola and Hawker, S.A., seismo's - maybe an M3.
Here's Geoscience's records of the tremors in W.A., S.A., and offshore SE of Esperance, W.A. - which is an interesting one.
The offshore one associated with the Great Australian Bight, which I have eluded to in the near past as a region I felt was going to crop up with a tremor/EQ. Perhaps pressures from the south and west (Indian Ocean) there.

Adelaide's seismo is looking like a wave motion atm - interesting.

I prattled on about the Galapagos Islands recently, as being a potential region for M4+s, and it has rattled with several of these in the last 12 hours or so.

The regions in the west of the Pacific won't let up with moderate EQ's and I see no real end in sight, in the short term at least.

Hawaii has had a few tremors, volcanic related (mostly) and I feel that they may feel another M3+ in the short term.

The action in the Pacific has revved up a few volcanoes and harmonic tremors are occurring in many locations too. The general peripherals of Yellowstone, and the odd one in the park itself, have been feeling some M1's, M2's and an odd M3. More to come for this region.

Oklahoma is still having the odd M2+, felt in surrounding regions.

An M3+, yesterday, in/near Pembroke, Canada, has been described as an explosive sound before the associated rattle.

The Marianna's (Guam) came up with an M4.6, as I felt it would (Marianna region), in reaction to the continual movements in the Pacific west, NW and SW. This EQ produced a "thump and sway" as one local described it. Apparently no damage.

For the moment, Duck.

Re: Earthquakes - 23/10/2013 09:18

Hi folks.

As I type this, PNG has just come up with another considerably sized quake - M5.8 at approx 65kms deep.
The western side of the Pacific Plate just doesn't seem to want to rest at the moment.
I get a feeling that there may be the chance of another M6+ in the near future...will see.

All through the Mediterranean regions (including from Spain/France and east across to the Middle East to Pakistan and India) have and will continue to spot with M2's, M3's, M3+'s and the odd M5's (and M5+'s).
The energies over on the Atlantic side of Europe may in bursts travel up the western countries (British, Swiss, Dutch regions and curving up and around to Poland and sweeping round to the regions like Romania) in the form of the odd M2 and perhaps the odd M4 (maybe '+' in perhaps Poland, Romania, Spain, Turkey, Afghanistan, Pakistan, Greece, the northern coastline of Africa, the sea/coasts of Saudi Arabia, Kuwait and a few other potential locations in this general region. These are not predictions, just feelings.

The west coast of the America's (north, middle and south) are still popping up with M's ranging from 2 to 5. This will continue. The west coast of the U.S. is intermittently cropping up M2's and M3's. The fault system associated with the San Andreas is still jiggling with smaller tremors here and there, but that is not uncommon. The region west of Eureka on the California coast is one region which has and seem to continue to be associated with some moderate type tremors/EQ's - it is at this general point that the fault running up from the southern regions, juts west away from the coast and then up again - stress point? The Cascadia Fault system continues on from where the previously mentioned fault heads west.

This post has taken me from the time of the PNG quake to finish...some interruptions (understatement) crazy

Re: Earthquakes - 23/10/2013 10:23

As I type this post, there has been nothing showing on any EQ register regarding this substantial movement on the South Oz/Vic seismo's. If I was to hazard a guess as to what this is, it could be a larger/moderate quake north of Oz or something in S.A....? It could be an aftershock in PNG or something else....
This movement occurred about 55->60 minutes ago (Sydney time)

Snippet from SA Minerals EQ registers
Posted by: duckweather

Re: Earthquakes - 23/10/2013 14:22

Just regarding that EQ register/image I posted above, there has been no record applied to this movement.
Now, when I see these seismo's behaving this way, it usually means that there has been a larger movement near the Oz coastline (other country perhaps, like Japan, Philippines for example); or a large quake in New Zealand, Indian or Pacific or Southern Ocean or Great Oz Bight etc...
Or...South Australia has endured a tremor/EQ which has effected a considerable area (felt wise).
Another thing is that a Vic seismo didn't register this movement. If Vic had - I would have suggested the movement may have come from S.A. or other region.

My guess is still that given the nature of the movements on the seismo's above, the energy came from above Oz and filtered immediately down through the centre of Oz, through to South Australia. I've seen this happen before, as I feel the lay-of-the-land in this 'central' region is more of a conductor/receiver of this sort of energy than Victoria, which between it and the due north of Oz, are landforms and structures (deep and shallow) which help preclude or somewhat block a direct line of energy passing straight down to Vic.....?
An M5'ish, for example, from PNG or eastern Indonesia can produce this kind of seismo display/effect on the group of seismo's displayed in the post above.

Then again, Daffy Duck could be wrong....but maybe not smile

Re: Earthquakes - 23/10/2013 16:35

4th post for today blush

Okey dokey folks.
That seismo reading (s) I gabbled on about in the previous posts was South Australia possibly.
Geoscience has just put up an M2.6 (10kms deep) for Spalding on their site, which seems to correspond with the time of considerable movements on the seismo's.
Funnily enough though, the size and number of the registers on the seimo's seemed to be indicative of a larger quake in a neighboring country...?
Anyway, I won't prattle on anymore about this one - might bore you to tears smile

These are not predictions, just feelings.

These regions, apart from Afghanistan/Pakistan regions so far, have come up with tremors/quakes in the general pattern I felt they may.

The Oceans, also apart from the Indian Ocean so far, have also come up with the quakes I felt they may.

The Pacific is still continuing to produce quakes in bursts, and the north of NZ and the South Island have had some EQ's I suspected may occur too. As with the west coasts of the America's.

The regions between and down from Taiwan, through Philippines, to Indonesia/PNG and across to the general island regions of Vanuatu, may come up with the odd M5. There may be a chance of an M5+ in the middle of the above-mentioned regions.

Along Sumatra and perhaps towards the Bay of Bengal, there may be an M4+ or two. This may be the region more towards the south of Bali in the seas/coastal region above the Oz mainland (not on the Oz coast).

Here's the link again for Geonet New Zealand quakes

Posted by: duckweather

Re: Earthquakes - 25/10/2013 16:40

Ok..finally got a chance to reflect on today's EQ's.

There has been a run on M5's in the Pacific and some of the oceans. The largest being the Fiji region, South Sandwich Islands and that one in/near the Bay of Bengal (Andaman Islands, India region). The Banda sea and Tonga, amongst several regions, have also rattled with larger EQ's.

The number of M5's and above appears to be quite numerous these days. As was my feeling about the Pacific, in particular, regarding the massive pacific Plate not being a happy character at the moment. The western side of the Pacific is continually active at the moment and I feel that there may be another larger quake or two in the short term.
I get a feeling that near Davao or Cebu in the Philippines may come up with another moderate (maybe ++).
I also get a wee feeling that the energy grumbling away in the Tonga/Fiji region may translate south towards NZ. This could mean that the Kermadecs and White Island may be agitated by this, and perhaps further down to NZ North and South Islands.

The South American western coastline and the regions incorporating the U.S. coast, Central America, Canada and Alaska may come up with an M4+. I am drawn mainly to Alaska and the west coast of South America....but could be wrong.

Hawaii may feel an M3 (maybe +).
Japan may feel an M4+
The English Channel or country on either side is drawing me to it for an M2+.
Germany maybe for an M3.
The east of Canada maybe for an M3.
The Mediterranean for an M5.
South of Jakarta/Bandung in the ocean - NE Indian Ocean/west of the Timor Sea.
Naha, NE of Taiwan maybe for an M3++.
Jeddah, Karachi and Aden are also a few locations which I am drawn to for tremors.
The seaway NE of Athens is another region which may feel an M3...M3+?
(Remember folks,,,these are just feelings - not predictions).

Australia has revved up a little with tremors cropping up in NSW, S.A. and W.A.. The regions experiencing tremors are fairly regular places for movements at the moment, even if 'regular' for Oz means one tremor in these regions every few days or more.
It wouldn't surprise me if the the north-western area of the Northern Territory and maybe the SW of Alice Springs (100's of kms away) came up with a movement of sorts.
Victoria may come up with an M2 towards the SE or east coast at some point...?
(again...just feelings)

For the moment, Duck.

Re: Earthquakes - 27/10/2013 11:35

Hi folks.
As I said yesterday, I have been distracted with the incident which occurred at midnight in our street. Unfortunately one of the cars associated with us was hit and we spent yesterday organizing various things regarding its repair.

Anyway, Mt. Etna has endured more than 20 (?) harmonic tremors surrounding its latest eruption. The following link on Volcano Discovery has great info on all of this action;
"Etna volcano (Italy): new paroxysm from New SE crater & video"

Something I find a wee bit of a pattern with is when the Pacific west is very unsettled - then calms somewhat, the Mediterranean region activates (or increases activity). This seems, again, to have been possibly the case currently.

The day before Japan's large quake, I had another horrible suspicion that a quake of this magnitude was going to possibly occur near Japan and that "water disturbance" was heavily sticking with me. Thank goodness this quake was some distance off shore and that the energy expelled was of a lesser extent than the M9 in the past. Even though it was a 'lesser' quake, the folks in Japan had about 6 minutes warning of an impending quake and were able to evacuate many areas near the coast, and Fukushima was evacuated.

The buoy halfway between the central north coast of Western Australia and the Indonesian coast (SSE of Bali), is showing very jittery readings almost constantly. This may be an indicator of further EQ movements yet to occur.
National Data Buoy Centre

New South Wales has caught my attention a little with their moderately regular tremors, the last one being an M1+ near Boorowah. There may be another tremor near the east coast or Canberra in the short term. I also feel that South Australia may have had a couple of rattles in the last 24 hours...
Geoscience

The seismo's on this display (Vic, S.A., NSW/Canberra) showed semi-simultaneous jitters before the Indonesian quakes. A similar 'pattern' is emerging currently and Vic is showing a little more (number of) slight movements too. We (Vic) may be in for a wee tremor in the short term..?

Good morning folks.
As I was out and about this morning (6am), I saw a beautiful (almost vertical) rainbow emanating from what appeared to be the location of our Police Academy (which used to be the theologate [seminary] of the Corpus Christi). This property is a magnificent place on top of the highest hill in Glen Waverley in outer eastern Melbourne. The curious thing was (well for me anyway) that the sun hadn't risen above the mountains yet to cast direct light on the area. But, perhaps rainbows don't need much light to form....?

Anyway, Japan has come up with another M5+ near Honshu. I found it interesting to observe that link to Japan's live seismo readings (link in last post) and this region was definitely jittering and triggering the odd minor warning signal when multiple small (M1+) tremors were being felt/recorded....warning of a potential for larger M's.

Indonesia (Banda Sea and surrounds) has been quite active and Taiwan came up with an M5 as I felt it would.
At the moment, Pakistan hasn't come up with tremors/EQ (that I am aware of) as I felt it might as hasn't SSE of Bali.
Obviously I don't wish for my feelings to be confirmed regarding the occurrence of EQ's as they usually are unwanted 'visitors' in many regions. Though, I am still not convinced that that region SSE of Bali/NW of Oz is settled.

Anyway for the moment,
Dawn Duck.

Hi folks.
Sorry haven't had a chance to jot a post since my last one...been very busy.

The Balleny islands region has just come up with an M5.7 - info here - list for today so far - all M2.9+'s - as has Sulawesi Indonesia and M5. several other regions have also felt M5's (in list in link).

The Prince Edward Islands region finally came up with an M5'ish I felt it may (below South Africa).

I felt a vibration/hum/movement go through here this arvo (mild) and quickly checked the S.A. and Vic seismo's, and there had been what may have been an M3 movement on the S.A. seimo's. Will wait to see if Geoscience puts up anything tomorrow....

and...hi Cosmic (naz) wink
yes and sometimes different approaches remain separate confirmed 'ideas' by a small number of persons and may not accept the concepts/hypotheses of some others. Generally speaking though, many people worldwide are open to lateral thinking and alternative ideas as possible sources of explanations for some of the natural happenings (EQ's etc..) in comparison, or in addition to what is 'on the table' as confirmed knowledge. (Hope that made sense)
Some natural occurrences never thought to be related in the past are increasingly being observed and considered as interrelated/inter or counter-effective to some degree. This emergent or increased understanding can only help in the human knowledge of the natural world.

As I type this the Macquarie Loop/Balleny Islands have gone 'off' again, with an M6....

Hopefully tomorrow I will have a better post to jot here folks.

Cheers for now, tired Duck.

Re: Earthquakes - 30/10/2013 09:58



The above pic is the current image (as I type) of the Absorption Map - Space Weather Station

The reason why I have put this up is, that I keep an eye on this sometimes in major Flare events and see if this has an impact on any regions which experience moderate to larger quakes. Sometimes there appears there could be a correlation with the occurrence of quakes and sometimes there appears not to be. This, apart from my own intuition, is the only map I follow - not to conclude where I feel tremors/EQ's may pop up, but as a small adjunct to my feelings. As you know, my intuition is sometimes right and sometimes wrong.
I see sometimes what feels to be a 'drag' in energy on some locations where the higher readings (re: the Absorption Map) have moved over/past some EQ locations. A bit like a delayed effect on some regions.
Now this map's readings may have little to do with EQ's, I really am not sure (not a scientist), but it is a curiosity when reflecting on where EQ's have occurred....

Also, notice where the Ballany Islands/Macquarie Loop M6's were, is where the image above show a concentrated absorption rate...?

The Aden (Gulf of Aden) region came up with a moderate EQ as I felt it may.
The California coast started up some rumbles of an M3 range in the last 12'ish hours. This I felt may occur after the larger EQ east of Honshu, Japan.
The east of Honshu has been jittering with M1's and M2's since then (though regular small jitters are not uncommon for Japan) and have had flutters of bursts of successive M2's (east Honshu). There have also been 'spot' tremors in the far north and far south of japan too, with the odd ones inbetween. It is almost like the the whole of Japan is experiencing constant very small movements with the odd small cluster of M1's + M2's in certain spots.
I feel that Japan may go on to feel another M4+.

The Arabian Sea is still catching my attention, and up into the coasts of Pakistan, India and Oman. The Gulf of Aden and up into the Red Sea (near and past Eritrea) may come up with another movement yet.

For the moment, Duck.

Re: Earthquakes - 31/10/2013 10:40

I thought for this post I'd focus on New Zealand's fault lines and quakes, in the current time. As well as jotting some thoughts on other regions.


Image - "Marlborough Fault System - Wikipedia"
Uploaded with Imageshack

In the last 14 hours or so, New Zealand has experienced 30 tremors/EQ's.
The strongest being felt near 20 kms west of Christchurch - M4.2 and a moderately felt tremor of M3.4 in the same location.
Other tremors, not all noticeable generally, have been dotted from the north to the south of New Zealand (both islands).
Generally, a majority of the tremors appear to be occurring in the northern regions of NZ and a couple beyond the North Island, in the direction of the Kermadecs.

I get a general feeling that New Zealand, not unlike Japan, will quietly rattle on in various locations for some time. The odd M4+ may crop up down the Macquarie Fault Zone, past the South Island (including towards Macquarie Island); In the Kermadec region; near Christchurch may feel an M4 (?); the NE coast of the North Island, in the general Gisborne region, may feel an M4 (?) and the Cook Strait may come up with an M4(?) also.

I get a feeling, along with the Indonesian/PNG/Japan/Philippine/Pacific Island general regions may go on to be rather unsettled for some time. With the odd M5 and perhaps an M6(?) occurring into November.

The numbers, for some reason, of 23, 3, 10 and 8 are sticking with me for some reason for November. (may mean nothing).

As I type this post, near Leinster, WA., has just come up with an M3.7 at (currently) 0kms deep. This is one of the larger tremors for Oz in recent times. NSW has had it's share of tremors in October, with a similarly sized tremor cropping up near Appin (NSW) and several other smaller tremors (not quite a cluster, but reasonably active in a fairly short space of time).

I get a feeling that Oz may feel an M4 before long (perhaps in Novemeber), as the general activity surrounding Oz (and in some spots on the mainland) has been substantial and may have provided/ing enough pressures on fault lines (?) to increase the likelihood of a larger tremor for Australia. This maybe the NT, NSW, VIC, SA or WA.
The NE of the Coral Sea has shown some interesting subtle buoy readings lately, which may be due to the plate activity (causing EQ's) north of this region.

Yellowstone grumbled with an M3+ yesterday and may crop up with another in November.
The California coast, also in November, may feel an M5 where the plates deviate. Mexico is sticking with me for some reason, as is still Puerto Rico.

The Mediterranean, in the short term, may 'fire-up' with tremors and the odd M3+, maybe an M5(?)....?

I have some other suspicions about some other regions, but I have to dash at the moment and will try to jot those later.

My jottings are not predictions - just feelings wink

For the moment, Duck.

Re: Earthquakes - 01/11/2013 00:08

Taiwan M6+ info here

This is the general region (between Japan and the Philippines) that I suspected may experience an M6(?).
The Philippine Sea plate (east of Taiwan) moves in a convergent fashion towards the WNW. The epicenter of this quake appears to be at a rather vulnerable point (just my feeling) where the plates meet. Let's hope that the folks there weren't poorly affected by this shallow quake. There will be water/sea disturbances - maybe not a tsunami in the true sense though.

This quake displays the considerable pressures I have mentioned suspect are being imparted in the west of the Pacific. There may be more M5's and maybe (?) another M6(?) to come in the western Pacific (maybe not Taiwan again).

Till tomorrow, Duck...

Re: Earthquakes - 01/11/2013 09:52

What an interesting last hour and half driving, with views all around Melbourne.
Nearly each direction I looked, there were swathes of ribbed clouds, some huge expanses of very defined ones. Some appearing 'before my eyes' and strangest of all was something I caught on camera (car) was 'something' leaving a smokey (?) trail then doing what appeared to be a sharp turn (45 degree angle direction change), a further trail then nothing. It looked almost like a perfect Nike tick.

Before all of the above, I have had an irking feeling that there is a 'strange' feeling in the 'air'. Almost as if it is a calm before....something...maybe a tremor here or something somewhere else. Maybe I am wrong.

A seismo in NW Victoria (Oz) has been showing some definite small intermittent jitters in the last hours, and what I saw today (cloud gazing) didn't surprise me. If Vic's gonna have a movement, that wouldn't surprise me. But these may be just this ol' Ducks' hay-fever affected brain cells in over-drive smile

Anyways, the east of Canada came up with a couple of movements as I suspected it would.
The Flores Sea, Indonesia has come up with 2 x M4's in the last couple of hours, but haven't shown up on the Global Incident map. They have been registered with GEOFON and EMSC - see here.

For now, Duck.

For info on the Chile M6+ see here - earthquake report

The above quake was near the coast and apparently hasn't produced a tsunami, but will have caused coastal water changes, maybe a minor sea level and wave behaviour changes.

Geoscience Australia has just put up on their site an M2+ for Victoria, SE of Omeo. Regarding my last post where I gabbled on about cloud formations and that irking feeling about 'something-in-the-air', this tremor may be a part of all of those hunches...?

For now, Duck.

Re: Earthquakes - 03/11/2013 11:34

Hi folks.
Finally catching up with the movements in the last 24 hours.

I thought I'd put some pics in this post to show how many substantial, M4+ and Australian tremors/quakes have occurred during October/last 30 days (this includes tremors/quakes which have occurred till now).

The first image (courtesy of Geoscience ) shows that last 30 days of tremors/EQ's in Australia only.



Queensland's M3 was not a surprise. Though I don't often mention this state as a potential area for regular tremors, they are not immune to such. Here's and interesting pdf by Kevin McCue - CQU Rockhampton QLD - "Historical earthquakes in Queensland"

The next images are 1) EQ's around the world as noted by the USGS for the last 30 days - in the ranges of M4+



2) is the image for the substantial EQ's M6+'s (except the US M4 also noted on this image) for the last 30 days.



These images above may not also include aftershocks which have been numerous after the large quakes.

Below is an image of the sea temperatures for the globe as at 17/10/13, which is only very slightly different to what it is 'today'. I thought I'd add this as a curious comparison to the regions (generally) which are experiencing sizable EQ's.



Thank goodness, it appears that none of the large earthquakes in the last week'ish have produced damaging tsunami's.
I still get a mild feeling that there may be a larger quake to come which may produce a water level issue though - unfortunately. I have this irking feeling that 'something' is brewing this year - and I hope I am very wrong here and probably will be.

This morning I woke up sharply at 3am, approximately the same time as the start of today's larger quakes beginning to occur. My ears were ringing like church bells. Couldn't get back to sleep, so the dogs and I watched the sun come up smile Oh and my beautiful baby budgies thought it was great to have 'granny' to talk to so early in the morning...

All above images uploaded with Imageshack and other images, apart from the Geoscience snippet, were courtesy of the USGS site info

Anyway for now, Duck

Re: Earthquakes - 03/11/2013 15:46

Cabargo, NSW, has come up with an M3.5 about an hour and a half ago.
NSW has been quite active and one region I have been watching and anticipating more movements for. I said in a previous post that we may see an M4 (possibly an M4+) in Oz in the short term.
The NSW region appears to have been more active than 'usual' lately.
If you look at the pic below of the Global Plate Motion - Wikipedia , and think of the quakes which have occurred off the OZ coast (neighboring regions etc.), one may get a general 'feel' for the pressures being expelled from the quakes, and stressors possibly building in various areas around Oz.
The Tasman Sea (as I have gabbled on about a few times before now) is one region which sticks with me for potential activity regarding the eastern states coastlines. I, personally, get a feeling that 'energy' is possibly being referred from New Zealand toward our way. (not a scientific opinion).


uploaded with Imageshack

The plate edges running across the top of the Oz mainland (under Indonesia) is active at the moment. Leading into and around the Indian Ocean and maybe incorporating the Southern Ocean (beneath Oz). The west-Indian Antarctic Ridge (Southern Ocean and due south of the SW corner of W.A.) came up with an M5 a few hours ago.

I feel that maybe the Mediterranean may come up with some tremors in the next few hours, and maybe from the west and eastern China, through to Turkey. Italy, Spain, Portugal, Jersey, (Belfast - Ireland; Plymouth or South Hampton - England) and France (amongst some other regions) are sort of sticking with me for maybe M2's, or a couple may feel M3's or the odd one may feel an M4.....just a feeling, not prediction.

For the moment and I'll probably be back for a 3rd post later blush ,
Duck.

Re: Earthquakes - 03/11/2013 20:33

3rd post for today...

Been watching the west of the Pacific and the Indian Ocean (in a couple of spots) throwing up EQ's one after the other, or so it seems in the last 10 hours or so. This is the considerable energy converting to movements I've been gabbling on about.
Global Incidents Map - Earthquakes
This is similar to what happened after Japan's M9, if I remember correctly.

I was watching Japan's seismo's when it's last quake went off. The movement/energy rattled the northern half of Japan, from Honshu up.

The east and western regions of China came up too, as I felt it would today.

There is also a buoy in event mode SE of Tonga - National Data Buoy Centre

The west coast of the U.S. may come up with some movements...

What next...?

Re: Earthquakes - 03/11/2013 21:38

I noticed on ninemsn places in China had a sun with reflections from ice crystals that made it look like there were 3 suns... So that area might be in for another big weather system. Just seems to link up with all the seismic activity, which might be from strong solar flares.
Something big could be on the cards?
Posted by: duckweather

Re: Earthquakes - 03/11/2013 22:03

Hi Steve O.
I tend to agree with you.
I also saw an ice crystal halo around the sun yesterday.
Including the solar flares, there has been alot happening in 'nature' in the last couple of days, which has left a feeling in me that something is not right at the moment...whether this means there is something substantial to come on the EQ front or something else I am not sure.
As I said in a previous post today, I woke up sharply at 3am and haven't slept since, as my ears were ringing like mad. I sat outside with the dogs for a while from 3.30am and there was a distinct (in my mind anyway) strange feeling in the air. It seemed electric'ish and/or as if 'something' was to show how unsettled it was becoming. As it has turned out so far, this could have been the ongoing moderate to larger EQ activity today.....?

Let's hope that my uneasy feelings earlier don't amount to anything and that the considerable EQ activity will peter out soon...

For now, Duck.

Re: Earthquakes - 04/11/2013 17:25

As I mentioned on the 30/10/13;

Quote:
The California coast, also in November, may feel an M5 where the plates deviate. Mexico is sticking with me for some reason, as is still Puerto Rico.


....off the coast of California, west of Eureka, where the plates deviate, has come up with that M5 I was suspecting would occur, unfortunately.
The Puerto Rico/Dominican Republic region also recently came up with a moderate tremor as I felt it would.

I have been watching Oklahoma lately as I feel this region may come up with an M4 (or an outside chance of an M4+), a bit of a feeling I can't quite shake off at the moment.
Here are some links to;
"Oklahoma Geological Survey Records 16 Quakes Around OKC"
and
"Fault Line Runs Right Through Oklahoma City" - November 2011

I dunno whether it is just me, but there seems to be an annoying current/slight vibration of some sort running through here this arvo. I have been noticing some jittery movements on our local seismo's (Vic., S.A. and NSW), which were evident before the EQ's north of Australia, in Indonesia and surrounds.
Or the energy, of sorts, is coming from the south of the southern states...or another thought is that it could be emanating from the east - New Zealand. This may even translate to a tremor in S.A., Vic. or NSW...? Will see...

The M5 I was anticipating may occur in the Mediterranean occurred as well as the south of Africa.

There is another volcanic island emerging in the Red Sea, see "Another new island formed during underwater volcano eruption in Red Sea" - The Watchers

For the moment, Duck.

Re: Earthquakes - 05/11/2013 08:53

Good morning folks.

Countryside, Illinois in the U.S. central-east has had an M3.7 (changed from a depth of 0kms to 1km). This, according to the USGS site was a quarry blast, the effects of which was felt by many in the nearby districts. It may have been felt as far away (approx. 400 miles) in Toronto, Ontario, Canada, to the ENE of Chicago.
It appears the history of Illinois' EQ's/tremors is generally focused in the southern general region of the state, which is closer to the New Madrid Fault region. There are faults (some unknown) which run around and through the Chicago region. I always wonder if quarry blasts and the results of other man-made activities, set off or have the potential to set off some of the faults....?

Will pop back in here later with another post smile
Cheers, Duck.

Re: Earthquakes - 05/11/2013 22:14

Hi folks. It's been a long day (beautiful sunny day) and have been watching Oklahoma, Ozzie seismo's and a couple of maps from a 'distance' (with a phone I am currently learning how to use like the youngin's smile ).

Anyway, I got up off the couch just then to check the Melbourne seismo, as I felt a strange sort of subtle vibration running through me and the floor - The seismo NW of Melbourne is showing movement which corresponds with this niggly feeling.
For the next couple of hours you can see this on this link - "750 S88b v"

Regions sticking with me atm, are West coast - US, Oklahoma still, Japan, from Taiwan down the east Timor, Chile, between Italy and Cyprus, Afghanistan and the Arabian Sea...for the moment...possibly for M3+'s and maybe M5's. Could be wrong.

For the moment (gotta play taxi),
Duck.

Re: Earthquakes - 06/11/2013 10:07

I was right last night when I said I felt that strange sensation/vibration running through me and the floor.
SE of Sale had an M2.5 at 3kms deep. Geoscience record
Apart from generalized (across these seismo's ) movements, there have also been localized movements registering on the Hawker and a couple of other S.A. seismo's. The seismo near Canberra also showed a localized movement yesterday.

Will add some more bits here later.
Cheers, Duck.

Re: Earthquakes - 07/11/2013 00:42

Gidday folks.
Finally got a chance to jot a post after a rather strange day.
First off, this morning, whilst driving my son to school, a car 'escaped' from a car park and took off backwards across our 3 lane h'way - mounted the centre strip and through the other 3-laner on the other side. All of us had to slam our breaks on (both sides - 6 lanes) - none of us hit each other or the car, and it ended up near a bus stop, in a garden bed. it was nothing short of a miracle that everyone/thing was unscathed crazy
Other strange things happened too, but I won't gabble on here about them, they are probably more suited for the "What the..." thread.

Anyway, W.A. came up with a tremor, as did the regions I felt would last night/24 hours - Vic., S.A. and N.S.W..

The U.S. west coast has been intermittently jittery. I am wondering if it is building for another M4+. It's behaviour appears to be a little temperamental.

The M4 off the coast of Oregon occurred along the same faulting line as the M3.2 ESE of it previously. In other words, the energy/movement travelled slightly northward towards Canada - parallel'ish to the Cascadia Fault Line off shore of the U.S./Canada border coast/off shore. Offshore Canada may come up with an M3+ (?)..??

Hawaii may come up with an M3 (+?)

India experienced an M5.4 - which is approx 6 days from the time I mentioned India may feel such. This appears to be associated with the Himalayas - a region which sticks with me alot.

I was just about to mention Colombia for an M4+, and as I am typing this post this region has just had an M4.5.

Japan is still a region which is strongly sticking with me for another M5 or maybe an M5+?. I have a suspicion that this region (e.g. perhaps near Honshu and the Volcanic Islands region further south) is still unstable. This might be an obvious statement to all, given Japan's EQ history, but this region/s along with Indonesia, the Arabian Sea, east Atlantic, western Pacific, PNG and east of, from Italy to Crete.....and a few other locations, are amongst some of the regions which may feel moderate quakes (some maybe substantial).

For November there may be another EQ which causes a water/sea issue; more meteorites and sonic booms; 'transformer/hum' sounds in Europe, U.S. and near the north of Australia - maybe NZ too. A region not usually noted for EQ's of a moderate size may come up with an M5...e.g. if we are looking west - we may need to swing our gaze to the east...or if we anticipate something in the 'north' look south....

I'll continue this post on Thursday....too tired atm.

Cheers for now and peace/safety to all.

None of the above are predictions...just feelings.

Re: Earthquakes - 08/11/2013 13:50

HI folks. I have been a little busy and haven't posted as much as I normally do (some may say "Yay" wink ).

Anyway, Canada came up with some EQ's as I felt they would, after EQ's in the off-shore region of California. The Queen Charlotte Islands region may respond to these movements with an M3(++?)
I feel that the California coastline/offshore is still brewing for an M4+.
The other regions I mentioned in a previous post have also come up with EQ's/tremors.

The region associated with the New Madrid Seismic Zone (regions including Oklahoma'ish, Missouri and so on) is still active and will continue to be so. As I said previously, this region may come up with an M4 (+?). There are faults running off the edges of this major faulting region, which I feel are 'sneakily' and sporadically showing signs of movements. It may be one of these pesky things which may produce a moderate quake.

Interestingly there was a tremor recorded in/near the La Pine graben fault section, which was listed with USGS as a quarry blast - M2.2 at 0kms deep.
Another quarry blast was recorded at Kalama, Washington State - M0.7 at 0kms deep.
Something I find interesting with some of the recorded blasts, is that they can be on or near recognized fault lines... confused.....

On a side-line, I mentioned some 'numbers' which were resonating with me recently (and still stand).
Quote:
The numbers, for some reason, of 23, 3, 10 and 8 are sticking with me for some reason for November. (may mean nothing).

So far, for November, the 3rd and the 8th have been days (incorporating Sydney time frame for the 3rd and 8th and future..) where there has been noticeably raised numbers of moderate to larger quakes. In mentioning those "numbers", my meaning or reference is to date or time).

For the moment, Duck.

Re: Earthquakes - 08/11/2013 23:05

Hi folks (and some U.S. visitors who are referred from my blog to WZ)

The location of the west of Eureka, California, is the exact location I was referring to in my previous post regarding the potential of an M4+ today. I have been observing the 'behaviours' of the tremors there and strongly felt that this quake was brewing, unfortunately.
See the Earthquake Report and USGS for further information.

Worth mentioning here (in conjunction with the info SunnyDays and other WZ's provide on the Solar thread) is the X class flare which has an Earth directed component, which may 'graze' past this planet sometime on the 10th or 11th of November. But as this topic is not one I am very good at, see here - The Watchers article and links for further information. I feel that once this has passed, there may be an influence on the potential for larger quakes in the zones day lit, as it sweeps past. Though I am not predicting such, I get a wee feeling that this may have some sort of a trigger for some quakes. Remember - I am not a scientist, so I could be wrong here.

Canada, I strongly feel, will experience an M4+ following the California M4+...

More soon, Duck.

Gee, I just checked the EQ map after I typed this post and saw that Canada has just experienced that M4+ I was suspecting may occur...hope all is well.

Re: Earthquakes - 10/11/2013 09:03

Good morning folks.

On the National Data Buoy Centre's site there is a buoy in 'event' mode NW of Samoa. It is reading deviations in water column height of 20 metres (approx) above level and approx 20 metres below level, and is still currently showing such. This seems to correspond with the general timing of the Kermadec Island's (many hundreds of kms SSE of American Samoa) EQ's 6 hours ago.

A few hours ago, the EMSC and GEOFON have both recorded an M4+ in Vancouver Island, Canada, but this has not shown up on the Global Map (EQ's) as yet. See one of the records here
I have noticed that some EQ's, even the occasional moderately sized EQ are not showing up on the Global Incident Map - EQ's.
Particularly many of the tremors/quakes in New Zealand;
Links - NZ statistics
All quakes/tremors for 10th November so far
Earthquake Report - including all NZ quakes/tremors over M2.9

The western California general coastline is still jittery and may come up with a few more M3's and maybe another M4+.
San Francisco Bay area tremors appear to have slightly increased in size (e.g. from the odd M1+ to e few more M2+'s) lately. Not only has the coast line been popping up with tremors, but the mountain range slightly inland is showing a few more tremors from San Diego through to Redding in the north (east of Eureka) of California.
(the U.S. western coastal region tremors are not uncommon generally).

The eastern states (including from the region of the New Madrid Seismic Zone, which is a little more central of the U.S.) of the U.S., e.g. Virginia's M1.9 some 10 hours or so ago, is coming up with a couple of tremors here and there.
But one thing I have noticed is that not all tremors/EQ's in the central regions for example, are showing up on the Global Incidents Map (if that is the one you follow).
For example, see Leonard Geophysical Observatory Oklahoma Geological Survey
Earthquake Track - Texas region (you can look up other regions here too)

Alaska, like the Cali coast, has been rattling along too with similarly sized tremors/EQ's to the U.S. west coast.

The east and western regions of China have been experiencing the EQ's I felt they may.


I'd also like to express my sympathies and prayers for the communities/folks in the Philippines who have not only had to deal with major earthquakes recently, but now, in some parts of their country, are dealing with nearly being wiped off the map by that super typhoon. Peace and safety to all.

I'll add a little more later.
Duck.

Re: Earthquakes - 10/11/2013 09:51

2nd post for today.

If you are interested in live seimo's from Canada, see Natural Resources Canada for current readings.
You can also look up other seismo stations' data on this site.

Vancouver Island region has come up with an M4 at a fairly shallow depth of 10kms. For 2 moderate'ish (M4 and M4+) to come up in a fairly short space of time) leaves a feeling of this being a region to be watched for maybe further consistent movements there.
The quakes are occurring between the major fault lines/plate edges there off the coast. The two latest quakes have occurred near where these two point meet - a vulnerable spot?

This is the energy I was talking about some posts ago, of some of the energy from the west coast of the U.S. translating into the offshore Canada region. So these M's occurring in Canada are, unfortunately, of no surprise to me.

From Canada's 'history' of quakes, most of their quakes are fairly shallow - within the range of 0kms to 70kms - which, in my amateur opinion, shows a fair chance of more movements near the surface than deep in the crust - the driving force being perhaps affected more readily by the 'top-layer' of EQ activity in the NE and E Pacific regions...(?) maybe being driven by energy from the SSE...? as well as other plate movements already known.

For the moment, Duck.

Re: Earthquakes - 10/11/2013 17:52

3rd post for today blush

Just squizzing around Australia's states and territories, and noticed some interesting cloud formations;
* from east of Cunnamulla, Qld. and SE down to west of Armadale in NSW,
* The whole of the west of Victoria, through to Adelaide.

These are just curiosities and not predictions of tremors, but the seismo's across these regions (particularly SA and Vic are showing intermittent, though consistent small movements. Sometimes this jittering precedes quakes off shore of Oz in Indonesia through to the Pacific Islands.

I get a feeling that some 'energy' is moving west across the Mediterranean towards Spain/north of Africa/France.

Japan's M5.6 may be one of a few to come soon. November may see another M6 in this general region, though I hope not and may be wrong.

There may be another M4+ west'ish of Eureka soon and the western Canada region may keeping popping up with tremors.

The region SE of Yemen and Oman is ticking with me for an M4+ in the near term.

The M5.2 in Tajikistan is not far from the region in Afghanistan, which I felt may have come up with a moderate quake. But it was not Afghanistan, so I was wrong so far with the country.

For the moment, Duck.

Hi folks.

SunnyDays, on the extensive Solar thread has probably posted a link to this animation of the Sun's behaviour - re: it's latest outburst , but as far as the influence on potential EQ's go, I thought I'd jot the link here too.
Apparently, any possible effects or ramifications on our planet will be notable from approximately late 12th November.
There is a video on Youtube here , which shows the Indian Ocean in daylit times (associated with the flare)???
I happen to feel there could be an effect on EQ's numbers and in some places intensity. The overall feelings I get of being a little unnerved by this flare activity and silent observation hoping for the best (hoping for no major EQ activity) is where I am at at the moment....will have to wait and see.

But, having mentioned the above and as SunnyDays is heaps more informed about this Solar action - head over to the Solar thread for her in depth posts on this subject wink

Victoria came up with an M2+ after midnight this morning. The location of this tremor, in Bairnsdale, is slightly north of the last noted tremor in Sale on the 5th of November.

The east of PNG -> towards the Solomons may come up with an M4, as may the south of Japan (?).

For the moment, Duck.

I couldn't agree more Petros.
They (Philippines) have endured horror conditions on both the EQ front and with the typhoon. What a terrible series of events for the communities there. The loss of life there is terribly sad.
I get a feeling that a majority of movements in the western Pacific may be from Naha region (near Taiwan) up through Japan and Kamchatka, swinging along the Aleutians...and around the regions incorporating countries NW of Oz, Indonesia/PNG and across the Pacific Islands intermittently. I am hoping the Philippines gets a long break.

Re: Earthquakes - 12/11/2013 10:21

There have been reports on the New Delhi TV website - here - that there have been several tremors in this region, around 4 hours ago (not sure of the exact times). This news report says there have been two, but the many locals are reporting several tremors. The estimate of the size of these tremors is around M3+.

There was an M4.4 in the Kashmir-xinjiang Border Region 9 hours ago, but this was north of Delhi, about 500kms away, over and beyond the Himalayas. I believe the two episodes of quakes (this one and the Delhi reports) are separate tremors (obviously the time frame is a little different) though feel the 'energies' that I have prattled on about before surrounding the Himalayas is still causing movements in intermittently all along the stretch of this magnificent mountainous range.

I get a feeling that the 'energy' coming up from the Indian Ocean, through India and involving the Himalayas, will continue to influence registering EQ's/tremors and the Arabian Sea, Red Sea, SE of Yemen, near Karachi (which I meant to mention yesterday....since yesterday some folks in Karachi have mentioned the feeling of movements there), Mid- and North Indian Ocean (and some other spots), maybe near Madagascar and possibly the Southern Ocean (south of the Indian Ocean) may experience movements.

Oklahoma is still experiencing moderately regular M3's (not showing up on the Global Incident Map). Actually some tremors even some moderately sized ones are not showing up 'immediately' on the Global Map. The Earthquake Report (link in my signature space below this post) is pretty quick at registering quakes as they occur...so you can check this along with the Global Map for current info.

Anyways, for the moment, Duck.

There are some odd spots popping up and some zones which are quite active.

Re: Earthquakes - 13/11/2013 09:11

Good morning folks.

A buoy SW of New Zealand is in showing event mode - [url=]here[/url]
It is showing a reading drop/deviation of 200 meters.

Unfortunately the Philippines had an M4+ at a reasonable depth yesterday, so hopefully because of the depth, it may not have caused too many issues for the communities there - they don't need any more troubles.

More tremors are tracking east, inland in
