Hi Matt. Hope all is going well for you in the States.
I'm glad someone over the Pacific from us can post some extra info on WZ as to how the ground rumbles are fairing there.
I think there may be some other visitors to WZ from the States, and it would be lovely to hear from them too about what they are experiencing.
Cheers, Duck.

I am here to confirm that any significant quakes as you mentioned is totally fake. They made a script to create chaos of the end of the world or doomsday 2012 bullcrap kind of stuff. There are no crazyiness going on. It just normal living life day of activities. Same for the 21st as well.

Goodness me...south west of Thousand Oaks (California, U.S. offshore) has just had an M6.4. I mentioned this possibility (exact region) in my blog, unfortunately. Will check to see what the ramifications of this is....

so far... current notice re: any tsunami

Restless awakening: Iceland shaken by 1,500 earthquakes in November

Here's an article regarding Iceland's tremors. If you're one for keeping an eye on live feeds (earthquakes), many regions' tremors such as Iceland's, are not seeing to show up on the feeds.

Cheers, Duck.

Melbourne University Seismic Station - School of Earth Sciences

For those in Melbourne (Gippsland and Castlemaine) and South Australia (not sure of the exact region of the seismograph here) who may be interested in the above links up-to-the-minute seismo readings, have a look at the link for the current activity (tremors) - interesting.

I have only just discovered this link (can't believe I've been so slow to find it) and confirms some of my suspicions about today's activity.
Hope you find it interesting wink

Nevada, U.S. west coast, is experiencing 'constant' rattles of M1's and M1+'s at the moment.
Global Incident Map - Earthquakes
So many in a short space of time. Hope this is not a prelude to something bigger for them.

Vanuatu's M6.8 (208kms deep) is hopefully deep enough not to cause any sea disturbances. No buoy's going off yet. Global Incident Map - EQ's
Would have been felt though.

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).

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.

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.

Edit; just one other wee thing, if I may blow my own trumpet here blush it is my b'day and the little cake with the candles, which usually shows up next to my 'name' isn't there frown It's ok...I'll be alright smirk

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
BE MADE BY LOCAL AUTHORITIES.

NO TSUNAMI THREAT EXISTS FOR OTHER COASTAL AREAS IN THE PACIFIC
ALTHOUGH SOME OTHER AREAS MAY EXPERIENCE SMALL NON-DESTRUCTIVE
SEA LEVEL CHANGES LASTING UP TO SEVERAL HOURS.

Just on a local note, the Melbourne University Seismic Station (Gippsland and South Australia) is rumbling away currently.

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.
(so says this daffy Duck smile , you make up your own mind (ear) of course wink )

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.
I've added another post to my blog regarding this. Also some info regarding the asteroid which is going to do a fly-by on February 15th, 2013.

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
