Stumbled across this Youtube video.
Thought you might find it interesting or entertaining crazy

NO PERSON is 'in trouble' in this vid, it is a bag of rubbish falling into the crater.

If you're interested in current volcanic activity, I thought I'd drop in a couple of links here and there in this thread which are interesting.

This one is about Costa Rico's Rincon de la Vieja volcano , which has now been deemed out of bounds for visitors due to increased activity.

I happened across this interesting newspaper article from 28th September,1901, where Captain Ramselins, master of the barquentine, Joseph L. Eviston, spotted what he thought was a volcanic eruption (of sorts) in Bass Strait, off Victoria.
The text in the section (right), which can be enlarged for easier reading, is interesting.

"Volcano in Bass Strait"

Here's a link to a terrific site, which gives some quality updates on Voclano 'happenings' around the world.

Volcano Watch - EP

Some of the earthquake activity around the planet is directly affected by the rumblings of various volcanoes. Some volcanoes, previously thought to be dormant/extict or 'sleeping' are showing signs of renewed activity - even in small doses.

First Tongariro (N.Z.) eruption in over 100 years

LATEST: A larger, molten eruption is possible if volcanic activity continues at Mt Tongariro.

The volcano rumbled into life at 11.50pm last night, sending ash and rock a kilometre into the air, prompting a potential threat warning for central North Island regions.

The "small scale" eruption was a total surprise, GNS Science said.

GNS scientist Brad Scott said there was strong seismic activity for about 15 to 20 minutes after the eruption, however in the 24 hours prior and hours since, there had not been any significant activity.

The eruption was purely driven by the hydrothermal system, generating steam rather than molten lava, Scott said at a briefing this morning.

Hydrothermal eruptions tended to recur and could escalate into more larger and energetic molten eruptions which spewed out lava and rocks, he said.

GNS was monitoring the activity on the mountain.

There is a bit of SO2 being released... It is sub-stratospheric (just). Be interesting if this is a prelude to something bigger.

Voclano Discovery is a terrific site for info, pics etc....
If I've posted this link before....apols smile

There is a lot of focus on EQ's atm, most understandably. But 'we' need to observe the volcanic activity as well (and I'm sure many people do). I feel there may be some considerable 'issues' building in some areas. There may be more simultaneous eruptions to occur at some point.
Underwater volcanoes, in some regions are becoming more active or are surprising some with their appearance.
Like those who are monitoring these underwater mounds, I have thought for a long time now that these 'unseen' characters will start to or increase in their being noticed as an important part of how our planet is behaving atm......

Tinakula Volcano - Santa Cruz Islands

This post is relevant to the earthquake thread as well.

The above volcano is erupting. With all the quake activity in this region, I wonder how big the ultimate eruption/s will be? Or if it is just 'energies' passing through/up/by....?

Well gee wiz...I came across this article just now which discusses exactly the type of energies I have mentioned in the earthquake thread.
The mental picture that the scientist builds, as you read the article, is spot on with what was going through my scientifically untrained mind.

Nearly choked on my breakfast when I began to read this...but then discovered we may be ok for another "100 million years"...I feel better now crazy

"Extinction Level Super-Volcano growing in the Pacific"

With what has been occurring for the Santa Cruz Island regions, the content of this article sort of 'confirms' the feelings I have been having about the where particular energies may be hovering deep below.
Even though a mega eruption of this description could express itself in other regions too, I have been 'stuck' on the Pacific region (near Wallis and Fortuna/Solomons (and surrounds)) for a very long time (years) now. But hey, I am no visionary or prophet (so don't rely on my words for scientific info.), but I feel that the volcano near Santa Cruz Is. is still one to keep an eye on for the time being. Though the energies there may 'move' to a region (far WNW [of the globe] or NE and/or SE of the Pacific).

I am a bit of a fan of antipodal impactor caused mantle plumes. i.e. the seismic shock propagates through the elastic mantle (and around the liquid core) such that there is a convergence at the antipodal point - which then creates a long lasting crustal weakness as evidenced by a "permanent" mantle plume / hot spot.



I am a fan of the Chicxulub impactor causing the Deccan Traps volcanic activity for example. And we also have known antipodal volcanic activity at similar times elsewhen. See Siberian Traps and Wilkes Land Impactor and the (suspected) Bedout crater.

I know that there is lot's of poo-poohing of this on the basis that for example the Chicxulub crater was not directly antipodal to the traps...



but there is the possibility that if the impactor hits at an oblique angle, then the antipodal shockwave convergence is shifted.




There is also another possibility, where it may be that there was an impactor that disrupted the antipodal mantle earlier, created a weakness but the resultant hot spot remained sub-crustal. There was then a second nearby impactor that then triggered the volcanic activity - and this one may not have needed to be "exactly" antipodal.

For example, the Morokweng crater in South Africa is antipodal to Hawaii. Whilst we can't be sure exactly when the Hawaiian Islands hot spot started, the northern islands are at least 80 million years old. The initial lava flows must have been much older. The 2 billion years old Vredefort crater is only a couple of hundred Km east of the Morokweng crater. It is possible that one reason for the enormous mass of the Hawaiian Islands is that they formed on top of a sub-crustal hot-spot caused by a very ancient previous antipode impact nearby.

And hence we now have super-volcanic hot spots like yellowstone, sub-Iceland and others, just waiting for a trigger to blow (or a hammer to strike to be more precise)... and set up another extinction event...

That's an interesting set of information Arnost.

When you consider that, regarding physics dynamics, when an object scores a vertical hit on an surface, the resultant energy is displaced in a fairly uniform fashion (that's assuming the surface it hit has no deviations in its form [such as a huge mountain formation] - with the strongest force from the impact being directed down from the impact point).
But, as you mention, if the object (e.g. asteroid) hit the surface at, for e.g. a 90degree angle, the energy from the force would be generally on an angle relevant to that angle of impact. A good experiment to see a possible example of these impact dynamics, is to use an egg (or a sphere, with a breakable surface and filled with liquid or powder) an piff ball bearings at it. This was one my experiments I used to show 'force' and displacement of energies.
I believe in cause-and-effect, and what you mention in your post Arnost is very interesting.

I'd better stop here grin I just get a bit carried away when talking about physics etc..

Cheers, Duck wink

Here's a very interesting article I came across regarding an under-sea volcano blow-out in the southern Pacific.
Curiously, I noted (in blog - for March) -
Quote:
I feel that somewhere in the western side of the Pacific, that an underwater volcano mound may become more evident.

This obviously only says a 'mound more evident' and appears somewhat vague. I quietly (actually) felt that this was going to be more than a mound being more obvious - sometimes I down-play my feelings about some 'maybe' events, as I don't want to be an alarmist or scare-monger.
I kept getting drawn to this general region for the potential release of such previously 'unseen' volcanic energy.

Cheers, Duck.

Hang on folks....just checking 'dates/times' on the last post. I think this volcano may be acting up atm., but I'm finding conflicting times/dates in other articles on this region.
Bear with me. I'll try and verify some more facts on this interesting story. (Maybe I need some reading glasses as well smile )

An explosion on 17 June produced an ash plume that rose more than 4 km, and ejected incandescent tephra up to 2 km from the crater. Some of the high-temperature fallout caused small fires in grasslands on the flanks. Ashfall was reported in Tetela del Volcán (20 km SW), Ocuituco (24 km SW), Yecapixtla (31 km SW), Atlatlahucan (30 km WSW), Cuautla (43 km SW), Tlayacapan (40 km WSW), Yautepec (50 km WSW), Jiutepec (60 km WSW), and Xochitepec (70 km WSW) in Morelos state. Ash also fell in Ecatzingo (15 km SW), Atlautla (17 km W), and Ozumba (18 km W) in México state. The Alert Level remained at Yellow, Phase Two.

But anyway, here's a link to an article about a volcano in Japan that has just blown 'it's stack'. This leaves me wondering if it's sister, Fuji, may become more active too..? Between earthquakes and volcanic eruptions, what's next for the poor folks in Japan?

I don't always get time to keep up to date info on all of the sections of General Science here so, here's a link to Volcano Discovery's page regarding all of the Volcanoes which are erupting. active and so on.

Volcano Discovery - Volcanoes - what is erupting

There seems to be an increasing occurrence of volcanic activity and for quite a while now, I have been gabbling on on my blog about the potential discoveries/recognition of submarine volcanoes and vents coming to life here and there, and this appears to be happening.
There seems to be, as I felt there would, an increase in 'energy' surrounding volcanoes, in harmony with several of the larger quakes. This dynamic earth certainly an interesting entity.

Now here's a possible volcanic vent which you may not want to have pop up near an airport or seemingly out of the blue at a bit of a distance from a volcano (described as 'dormant'). I personally don't believe in 'dormant' volcanoes. I tend to think that where there ever has been any kind of volcanic activity, the old vents/exit points, I feel, are still vulnerable places. Also, it wouldn't surprise me in the least if Mother Earth (magma and associated volcanic materials) pushed their way up in new spots to surprise us all (well, some of us).

Yeh Bello Boy.
It's fascinating, but on the other hand, I think I'd be hoofin' it to test the emissions of this thing (which I am sure the Italian scientists are doing). From what little I know of volcanic vents, they don't 'stray' too far from the live activity of the related volcano. I am guessing it may be an off-shoot of some deep activity. I can't get past a feeling of a possible sub-marine volcanic origin, or it could be a release from a pressurizing land volcano (maybe one, up till now, considered inactive or even extinct). But I am not a scientist with intimate knowledge of this region, so I may be way off with my feelings here.
It will be interesting to follow the investigation of this one....
Cheers, Duck.

P.s. I have observed the tremor activity for the Mediterranean region for the last 7 days (ish) and there have been heaps of tremors, including some moderate ones, all over the Mediterranean region, and most of them have been at a fairly shallow depth - up to and around 40kms deep, not like many in the Pacific and South America regions - where many have been very deep. But that's another story for the earthquake thread.

Here's a video of that volcanic vent near Rome airport. Don't turn the sound up at the beginning. The sound 'kicks in about 8 seconds from the beginning)

Been trying to find some indication that the Rome situation has been confirmed as volcanic.

I saw speculation that it could be volcanic or perhaps just a burst pipe. I would of imagined this could have been confirmed by now.

Yeh Locke...currently I am not 100% convinced it is volcanic - 80/20 (20 being something else - pipe?) at this point.
I would imagine that it's emissions have been tested and though it seems to be behaving like a volcanic vent, it too is behaving a little like, let's say, a hot water pipe - but this in a roundabout at an airport? (Do they utilize hydro-thermals in Italy?)

The way the mud is being blown out of the hole, looks to me like it has an air blast, mixed with a heat source, combined with moisture - but not the saturation of the water bursting from a broken water pipe.....it's a bit of a mystery.

If it is a volcanic vent...I'd be looking for it's sisters, it's mother or if it is a distant grandchild of a grumpy senior member of a volcanic family... crazy

I'll see if I can get a final confirmation on this too Locke.

Cheers, Duck.

Ok...I've done a quick skip around Youtube and some other sites.
I've posted two vids below which show similar behaviours to the Rome airport bubbler.

I am going to say that I am quite convinced now (99%) that the Italy airport bubbler is volcanic. Apparently these 'vents' are not really uncommon in Italy. One of these killed a herd of farm animals in a field in Italy, when they apparently breathed the poisonous gases in.

Anyway, check out the behaviours/sounds of confirmed volcanic vents in the vids below and compare them to the Itlay vid. Also, apparently the viscosity (moisture level) of the mud spirting out of the vent's hole is due to the season/water table level - according to one website (not a science one). I would need to learn more about this.

Cheers, Duck.

I've been a bit remiss in putting regular info on the volcano thread, even considering there is so much volcanic activity in the world at the moment. So here's a link to Volcano Discovery's current active volcanoes list and map

I've been quite interested in the following 'story' surrounding Ethiopia (which we have chatted about before) and here's a new article regarding a magma pool below Ethiopia that scientists have been honing in on to study currently.

"Giant reservoir of magma under Ethiopia may explain how continents break apart"

And... here are some maps/pics of the area;

There is so much volcanic activity going on in the world at the moment.

Below is a new video of a new island being 'born' off Japan's Izu Island region.

Apart from approx. 35 volcanoes erupting around the Ring of Fire at the moment, below is the best video I have seen so far of Japan's new volcanic island, which is continuing to grow.



On another interesting note about Pakistan's newest volcanic island, apparently it is reducing in size, which is frustrating locals because there is now less of an opportunity to earn income from the tourist trade.

For now, Duck.

Cheers ozone doug.

I reckon this volcanic island is going to be more permanent than the one in Pakistan, because (in my un-scientific opinion) it is spewing out lava which will harden to rock, possibly forming some firmer foundations for this structure. Unless it collapses from within and sinks at some point, due to a 'withdrawal' of the forces creating it...will see.

The Ring of Fire is one angry beast at the moment. I get a small feeling that this 'energy' (volcanic type) may creep or push further west, SW, NW, north and east around the ROF (into other old vulnerable spots - some considered dormant) or under some other coastlines of some continents and may also produce some more of these mounds in the future. The pressures, with all the volcanoes activated at the moment, seems rather highly charged - the "cup-may-spilleth-over" so to speak. (Amateur thoughts of course).

Cheers, Duck.

Yep and impressive photo DW.

For my 2 bobs, given the reference that the cloud climbs 1KM up, then the "fire pillar" is more likely to be a pyroclastic(?) lightning strike. Doesnt matter, impressive whichever.

I can see what you mean about the lava flow Rorschach...
With the comparison of the two pictures, and considering the look of the night pics orange 'glow', it makes better sense that this is a flow and perhaps not a pillar of fire.
Thanks for that wink

in the eq thread, some time ago, i mentioned my feelings about more under-sea volcanic behaviours potentially occurring as a consequence of major plate activity.

see the link below for some articles regarding this happening. the latest to be reported on is one in/near the solomon islands.

volcanic eruptions - EP

volcano discovery is a great site.

volcano discovery - volcano webcams see drop down list top left of screen to choose a volcano location/country

It's incredible isn't it Rorschach.

So many volcanoes going off, spectacular sights mixed with the problems some of them are causing for local communities.
For an explosion to be heard 200kms away, imagine the power behind that? wow
Mother Earth makes me feel like an ant sometimes.
All of the volcanic emissions must be having some sort of effect on the atmosphere.

It is real. Volcanos last erupted on the Australian mainland about 4-5,000 years ago. The local Aboriginal tribes in the areas around Mt Schank and Mt Eccles have stories of the eruption and how it changed the landscape.

I am aware of the Newer Volcanic Province and have climbed Mt Shank on a few occasions. What I am not sure about is the fact that hotspots stay in one place and the crust moves over the top of them creating a chain of volcano's such as the Hawaiian islands.
With the possible formation of a volcano in bass strait it seems impossible for the newer volcanic province hotspot to be creating this new vent. My reasons in saying this is the Eastern part of the field is the older part of the volcanic region and Mt Gambier and Mt Shank are the youngest formations and are located on the western side of the province. Either the tectonic plates have changed direction, the hotspot has moved or a new area is forming under the mantle. going from previous eruptions you would expect a new volcano to form somewhere west of Mt Gambier/Mt Shank, perhaps of the coast of the Coorong, Not in the middle of Bass strait.

Hi guys.

The following is my very, very generalized feeling regarding hotspots, plate movements and volcanoes.

I feel that hotspots have the potential to move and that some plate activity (causing EQ's and volcanic behaviour in some cases) is driven by the hotspots and upwellings.

There appears to be 'permanent' hotspots, like Hawaii, but there may be potential for others to develop if the energy conditions are right.

The volcanic activity, or general lack of at the moment, in Australia may be that there perhaps isn't enough of that driving energy affecting the Oz mainland, considering we are situated fairly central on the Australian Plate. But, this is not to say that some of the upwelling, plate and other activity causing some of the volcanic activity increase in other regions surrounding the Pacific Plate and Australian Plate may not 'splinter-off' in small ways into the edges of our plate - which may at some time cause some jitters in our volcanic plains here and there.
It could be a bit like the 'big-guy' stealthily poking at the arm (edge), sneaking a bit of that energy into our region, but not enough at the moment to cause concerns of a volcanic eruption on the Oz mainland.
I guess that if Mother Earth really got 'boiling' into overflow/overdrive with upwelling and plate movement, we may see some jitters in some volcanic regions in Oz. For this to happen, I am guessing that a larger event to the south or east of Oz may need to occur for there to be enough power to cause some of our volcanoes to react by degrees.

Just a thought,
Duck wink

Just as a matter of interest, I came across an old article, that I had forgotten about in my bookmarks, which discusses EQ's, volcanoes etc., in Australia.
I'll jot the link here, but it is also relevant to the earthquake thread;

Hi folks.

The link below to CanIndia highlights a current article about a fissure which has opened up in the earth, which is spewing "flames and hot liquid steam", akin to a volcanic behaviour.
It is located NW of India, on the southern edge of the Himalayas.

Hi perrywinkle wink

I have a small chance, finally, tonight to have a quick surf around the net to look up India's volcanic history, and so far I have found this;

* On August 7th 2009, Earthweek reported on a mountain explosion on the 27th July 2009. This blast/explosion spewed 'water' down the slopes of the mountains, into peoples homes. It also possibly contained hydro-thermal gases and sulphur. A crater of 300 square meters and 20 feet deep opened up.
This report can be seen here, including map showing location

The Times of India (6th June 2014) has stated;
Quote:
Palampur SDM Bhupender Attri said a team of geologists from state had confirmed small scale magmatic activity in the area.

As chances of this activity escalating in coming days cannot be ruled out, a GSI team has been called to study the area and check the strata. "Flames were witnessed so possibility of reoccurrence cannot be ruled out. Now we are waiting for the final report from GSI team," he added.

Former state geologist Arun Sharma said occurrence of such a volcanic eruption has been reported for the first time in Himachal Pradesh but the presence of magmatic substance is not new to the state. He said that existence of hot sulphur springs at Manikaran, Kalath, Tattapni and Vashishth confirms that magmatic material is present underneath these springs.

Times of India 6th June 2014

So...the reports of this activity actually don't surprise me. The combination of EQ activity and the nature of the geology etc. there, this possibly may be one of those 'surprises' that Mother Earth is offering up - which I have hinted at in the past.
Hopefully this activity will not increase to an extent which could cause problems for the folks there.

This may not be the only region in the future which may see some 'unusual' activity for 'their' location....

Cheers, Duck.

Hi folks.

There is so much volcanic activity occurring around the planet, it can be hard to keep up with all of the info.

Below are some links to some interesting articles and sites to provide some up-to-date info;

"Victoria's [Australia] volcano count rises" - Monash University - 26th June 2014

Voclano Discovery

"Indonesian Volcano Mount Sinabung Sends... Business Times

Volcano Live News - John Seach

Interesting times we live in.......

Cheers, Duck.

Duckweather'ays "There is so much volcanic activity occurring around the planet, it can be hard to keep up with all of the info."
Interesting Duckweather. Natural climate researchers are all talking about the high correlation of volcanoes and a solar downturn, of which is underway. The Natural cycle community is expecting increased volcanic activity including some larger events
Your independent comment certainly caught my eye

Hi crikey.

It is actually a bit of a curiosity, let alone a bit concerning, to see so many volcanoes going off or at least regenerating, and even some once considered 'extinct' or dormant showing some grumbling.

I think we may even see some more ocean based volcanoes possibly bubbling here and there. There may even be a region/location where there could be a 'surprise' volcanic behaviour. Remember the NW Indian volcanic activity recently, where there was a fissure open up and was spewing volcanic substances? That was very interesting and obviously probably a little worrying for some of the folks there.
Also the volcanic islands which have risen and fallen again in recent times. The Japanese 'sea' volcano has actually joined with part of the Japanese lands, effectively expanding the land size and rewritten the 'mapping' of the region.

I reckon that some volcanic activity may occur away from where the plates subduct (can cause nearby volcanoes to activate or be further irritated) inland on some continents....?

I think the Natural Cycle community may be quite right there (though I don't know much about the science of Solar/Sun).

Cheers, Duck.

Hi again.

Speaking of the Japanese growing island land mass, a new article has just been put up on The Watchers regarding yet more volcanic activity making a spectacle of itself...

"Growing Japanese island and volcano Nishino-shima erupts ash plume 3 km into the air" TW

Hi folks.

I got thinking about Victoria's (Oz) volcanic regions and found the quote/partial article from The Age - dated August 11th, 2008.
It is interesting info.

Quote:
GEOLOGISTS HAVE CLASSIFIED VICTORIA'S YOUNG VOLCANOES INTO THREE MAIN CATEGORIES

LAVA VOLCANOES

Lava volcanoes built the western lava plains. Very runny lava from these volcanoes streamed away, forming many of today's broad low hills.

Lava volcanoes with stickier lava created much steeper slopes. The lava accumulated in and much closer to the vents.

- Mount Hamilton, near Westmere

- Mount Blackwood, near Bacchus Marsh

- Mount Widderin, near Skipton

- Mount Gisborne, near Gisborne

- Melbourne Hill, near Lancefield

- Hanging Rock, above, near Macedon

- Camels Hump, near Macedon

- Blue Mount, near Trentham

SCORIA VOLCANOES

Scoria volcanoes are much more spectacular. Blasts of escaping gas spout out huge glowing fountains of frothed-up lumps of lava. It accumulates around the vent, producing cones.

Lakes of lava often formed in the cones, and sometimes broke through the crater wall and flowed for a distance. Breached scoria cones like this are very common in Victoria.

Many solidified lava lakes can now be seen as discs capping volcanic hills.

- Mount Elephant, near Derrinallum

- Mount Warrenheip, near Ballarat

- Mount Buninyong, near Ballarat

- Mount Moorookyle, near Smeaton

BREACHED SCORIA CONES

- Mount Noorat, near Terang

- Mount Shadwell, near Mortlake

- Mount Warrenheip, near Ballarat

LAVA CAPPED

- Mount Aitken, Red Rock and Mount Holden, between Sunbury and Gisborne.

MAAR VOLCANOES

When hot magma rises into rocks that are close to the surface and contain lots of ground water, high pressure steam explosions blast magma and surrounding rocks into clouds of small fragments. The fragments build up to form a ridge around a shallow crater. These are maar volcanoes.

- Lakes Purrumbete, Keilambete and Bullenmerri, near Camperdown

- Lake Terang (dry), near Terang

COMPLEX VOLCANOES

- Tower Hill, near Warrnambool, is a group of scoria cones in a large, lake-filled maar crater.

- Mount Rouse, near Penshurst, includes a large scoria cone with several smaller craters that produced a lava flow that is the longest in western Victoria, over 60 kilometres.

- The scoria cone eruptions of Mount Noorat, Mount Leura and Mount Warrnambool have almost buried their former maar craters.

GROUND ZERO

Volcanic activity in Victoria climaxed between 360 and 370 million years ago during the last part of the Devonian period. At least six giant caldera volcanoes were active, some of them at the one time. Eruptions would have blanketed the surrounding areas in thick layers of ash, having a devastating impact on vegetation and early aquatic life. The gases and dust sent into the upper atmosphere mean the eruptions would have been felt globally.

All of this ash has long since eroded, leaving only the harder volcanic layers that filled the calderas. These remains now form Mount Macedon, the Dandenong Ranges, the mountainous region between Healesville, Warburton and Eildon (including Mount Donna Buang and the Cerberean Ranges) and near Violet Town, in the northern part of the Strathbogie Ranges.

When you tour around near and behind San Remo in Victoria, around abouts the region of the Anderson Roundabout, where the Bass Highway intersects with the Phillip Island Road, you can see some lovely rolling/mound formations. I have toured Victoria (and New Zealand) many, many years ago doing photographic studies with my father. During these trips, I learnt to become a little obsessed with landforms/structures, and especially craters of various kinds. We had several of these trips from when I was a little tacker and never got sick of them. It is a surreal experience standing in a crater (not a live one of course) wink

Anyway, for now, Duck.

Hi folks.

Just as I felt there may be (and may be rather obvious actually), with all of the volcanic activity going on, there may be some considered 'extinct' or dormant volcanoes showing signs of activity.
This article from EP is just one observation amongst several regarding several volcanoes showing signs of activity.

"‘Extinct’ Costa Rican volcano being re-examined for activity, volcano dormant for 3,500 years"

I feel we will see some more inland locations or near coastline volcanoes showing signs of very slight to moderate irritations or increased ground or lake temperatures in the near future. There seems to be enough aggravation caused by plate movements (and faults in some places) and upwelling (magma and heat) happening in the 'regular' places across the planet, that some of this behaviour (I personally feel) is bound to spread to other regions.
As for the sea volcanoes, I get a gut feeling that where the very long sea plates meet, for e.g. the trench running down the Atlantic (and possibly some other similar types of locations) may also pop up one or a few 'little surprises' in activity. I don't mean global disaster, but irritations which may become apparent in some places. The evidence for such may be discoloured waters, disturbed wave-tracking behaviour, risen land/sea forms and maybe even a small rise or dip in a local coastline somewhere.

The above are just my amateur thoughts, not scientific knowledge wink

Cheers, Duck.

Things starting to look very interesting in Iceland with significant earthquake activity surrounding the Bardarbunga not too far from where the infamous 1783 Laki eruption wrought devastation.

There have been more than 3,000 minor quakes or tremors since Saturday and activity does seem to be increasing with a 4.8 magnitude only 2.5km from the surface earlier today.

The entire area has a thick 5-600m glacier over much of it thus giving a significant flooding potential should an eruption occur.

Scientists monitoring the volcano have stated that the level of earthquake activity is an indicator of significant volumes of magma moving but there is no guarantee that it will reach the surface to cause an eruption.

Hi folks.

There are a few volcanoes in active mode or are actually erupting at the moment, as we have eluded to in the earthquake thread.

Below is a live webcam of the Iceland volcano which has produced a fissure, 600 metres in length, and is spewing steam/smoke.
Better describing the activity here is The Watchers report
and this live stream below;



Given that volcanic activity also produces earthquakes and harmonic and other tremors, this thread will overlap with the earthquake thread.

For now, Duck.

The fissure near Bardarbunga continues to pour out lava at volumes not seen in Iceland since the 19th century with no end in sight.

This has not been an explosive eruption so far with no impact on air travel and so not much fuss has been made in the MSM, but make no mistake this has the potential to be an unprecedented event for modern civilisation.

Some things worth noting:

1. Bardarbunga is Iceland's second largest volcano and its caldera is showing signs of collapse. Subsidence of more than 20m has been measured in the caldera that is capped by a layer of ice over 700m thick. There is a possibility if the caldera does collapse that we could see an explosive eruption.

2. The fissure eruption is releasing massive quantities of SO2 which can have significant health implications to those downwind. We have already seen elevated levels in Norway and Finland, whilst levels in certain Icelandic towns have also been measured at more than 10 times safe limits.

3. Following on from point 2, the lava being released from this eruption has much higher gas levels than those found in some non-Icelandic volcanoes (like Pinatubo).

4. Should the current eruption be maintained for an extended period and/or the release of lave increase, the amount of SO2 released may start to impact global temperatures in the Northern Hemisphere. It should be noted that whilst Pinatubo released significant amounts of SO2 it did so from a position far closer to the equator. Historic events in Icelands past have had a significant impact on NH temp measurements.

To sum up. There are any number of scenarios from an explosive eruption to continuing massive releases of lava and SO2 that could have significant global consequences. These scenarios are now much more a realistically possibility and this is why Icelandic authorities have expressed concerns.

On the other hand if activity subsides quickly or at least continues at a reduced level then the global consequences should be minimal at this stage. Unfortunately, at the moment, the activity is showing no definite signs of ramping down.

In fact in the past 24 hrs we've seen an increase in larger tremors near Bardarbunga and tremors start to propagate out along the ridge to the West after previously being confined to an area from Bardarbunga to Askja.

Definitely a worrying situation.

I'm not sure that there will be much impact on temperatures from this. You need the SO2 to somehow get to the stratosphere. Plinian volcanoes like Piantubo and El Chichon with high SO2 in the ejecta can get the SO2 high into the atmosphere, and for them temp impact to be be global, you need them to be equatorial. If you look at the 1912 Katmai / Novarupta eruption, [the largest volcanic explosion last century *] then you will see that there is nary a blip in th temperature record...

* Novarupta had an estimated emission of SO2 in the 5,200-20,000Kt range [Palais & Sigurdsson 1989; Hammer et al., 1980] and so probably larger than El Chichon (7,000Kt) and more probably somewhere in the Pinatubo range of SO2 emission (20,000Kt)

Hi folks.

I thought I'd add a couple of interesting articles regarding volcanoes and volcanic sea mounts.
Regarding the sea mounts, the following report confirms what I have eluded to in the past re: more volcanic mounds to be discovered (which were previously unknown) which may take scientists by surprise.

Colombia-Ecuador border earthquake sparks concern of possible imminent volcano eruption

"Thousands of undersea volcanoes revealed in new map of ocean floor Posted on October 22, 2014" - EP

It does not surprise me in the least that more and more volcanoes are 'awakening' these days given the amount of plate activity and the potential of other influencers having an effect on volcanic and magma movements.

For now, Duck.

Hi folks.

There is alot of volcanic activity around the globe these days. But the flow of lava in Hawaii is strangely beautiful, even though it is causing some issues for the folks there.



Across the planet, many previously thought of extinct or 'silent' volcanoes are murmuring, some to the surprise of the scientists and some local folks alike.
Without sounding arrogant, I am not actually surprised at all that some of the regions with 'extinct' volcanic activity are showing behaviours akin to 'awakening' (various degrees). There appear to be some regions which may pop up a little surprise or two in the near future. Some of the tremor, presumed just faulting activity in some places, may actually be sneaky volcanic related activity......

Cheers for now, Duck.

Hi folks.

Some time ago I mentioned keeping an eye out for undersea volcanic activity which will present itself (in various places across the globe - but I may have mentioned the Pacific specifically).

See the below mentioned report regarding such a thing occurring in the pacific near Tonga.

Undersea eruption of Hunga Tonga-Hunga H...anuary 06, 2015

I have felt for a long time now that with all of the major activity in the plates around the Pacific, that along and near those edges there may be emergent or regenerated volcanic activity. The energy (including magma deep plumes) may also come to emerge in other regions of the Pacific, which have been silent or their position may not be currently on record as potential 'weak spot' for the potential of emergent activity.
I just feel that there is alot of stress being released in the Pacific (and some other spots- like the Atlantic etc.) over some time now, that I feel there just may be a possibility of these 'sneaky' undersea type of spots 'giving' a little or a lottle with the pressures.....

Here is a site which I must visit more, as I rarely do, to learn more about current volcano activity worldwide - Volcano Discovery

Volcano Live - with John Seach is another excellent site.

For now, Duck.

Yeah it's definitely a spectacular eruption, that's for sure! Haven't seen much night-time footage of volcanic lightning within the ash cloud yet but heard the tail end of some on the news being captured.

The 1st image below shows the latest ash concentrations as detected by multiple satellite sensors via the Support to Aviation Control Service at 12:34pm AEST.

The 2nd image below is the experimental version of the official ash advisory issued by the Buenos Aires Volcanic Ash Advisory Centre which goes out to 12:30pm Fri (the red outline indicates the potential outer edges of the volcanic ash).

The 3rd image is the result of a job I ran using the volcanic ash dispersion component of the HYSPLIT model. The higher ash concentrations are shown in purple. Probably too early to say with certainty how localised or widepsread any disruptions to aviation might be in the longer term though:

Culbuco eruption is reported on ABC tonite,to have reached 20 Km(may need verification?) which puts the plume well into the stratosphere. The effect of volcanic eruptions on stratosphere and climate in general seems to involve the injection of sulphur compounds, dust particles and perhaps other gases.

A lot depends on the volume of material getting injected into the stratosphere and in the case of dust -particle size. Also the effects may lag for quite some months.

It’ll be interesting to see what happens in the next little while - if Calbuco keeps erupting to get a handle on the volume of material thats getting pumped at this level - it may not need to reach the proportions of Pinatubo to have an effect because it has clearly breached the tropopause from it’s position >40 south. Only a small proportion of eruptions manage to do this.

It will be very interesting to see any future effects on the climate from this one. From the footage I have seen it appears as though it is pumping a LOT of particulate matter into the air so it should manage to cover a large area of the southern hemisphere.

One of the reasons why I followed volcanos so keenly was because of the correlation between volcanic events and El Nino.

So it will also be interesting to see what happens to the Pacific ENSO situation where we are hovering at the start of an El Nino. It may be that, unlike the two preceding La Nada years, this event will push the Pacific into a full blown Nino.

Hi Michael (ozthunder).

That's a great question and if I was to give you my opinion, I'd say that there is a good chance of some activity occurring in the next 2000 years. But....we may see some very minor niggles sooner than that. With the incredible number of volcanoes going off around the world in the current time/s, the percentage chance of Australia, possibly in our volcanic regions, has risen by a small percentage. (Remember; this is just my amateur opinion).

In my 'books', no volcano is extinct. Every recognized volcanic mound, mountain on land or under the sea has had varying degrees of magmatic pressure in the past to have created these formations in the first place. It is a matter of time before some of (or many) these 'weak spots' could reactivate....or new presentations of weak spots in the earth's crust (or in plate edge regions) may occur. That's just going on the large number of volcanic activity on the planet atm., and what has occurred as volatile times in the past (even before 'modern' man kept records).

I feel that there are old worn 'tracks' (historical and possibly new ones being formed here and there) of where magma has come to the surface or run around under the crust, and the connections between them may become more apparent as science discovers their extent. I feel that man is yet to get a complete picture of the actual deposits and locations some of the 'tracks' and the linkage between many of them...remembering it is awfully difficult to 'see' some of this possibility and 'we' have to use the best technical instruments currently available to build the best picture
'we' (man and science) can.

I have put a couple of links below regarding past reports on our volcanoes and the thoughts of scientists;

"Volcanoes 'due to erupt' Date July 6, 2011 " - The Age - regarding Victoria's volcanoes

"Australia: The Land Where Time Began A biography of the Australian continent "

We may see what may be some harmonic tremors in the future (when I don't know)....some activity on the seimo's in the past in our (SA and VIC regions) have displayed what looked like a smidgen of harmonic tremors - BUT - my observation may have been very, very wrong folks.

I don't discount seeing some minor(?) activity in my lifetime...we will just have to wait and see....

Cheers, Duck wink

The reason I ask is that 20 years ago I visited that western Vic area and was amazed at how recent some of the geology and landscape looked.

I suspect that the last eruptions 4-5k years ago were no random dates. That coincides too much with the flooding of Bass Strait after the last ice age.

Hi ozthunder.

I only have a basic knowledge of volcanoes in Victoria (or any where else for that matter), so I can only offer up some links which may describe 'current' knowledge of such activity wink

Note in the following link there is a mention of'
Quote:
Love et. al. (2004) have suggested that they may be generically related to the volcanoes in the area.
which refers to an image in this link which shows various earthquakes in the western side of Vic - in proximity to some known volcanic formations;

Volcanoes & Earthquakes in SE Australia - Uni of Western Aust. 2004

"Volcanic eruptions long overdue in SE A...lian Geographic

30 June, 2014 11:37AM AEST New volcanoes spotted in south west Victoria By Georgia Westgarth

Science in recent times is realizing/discovering more old volcanic formations, which if you travel the lands of Victoria, it is not hard to see some curious little volcanic sites poking at your eye - as you have mentioned regarding what you have observed ozthunder. I don't mean to be a 'smarty-pants' here, but some of the formations science is now recognizing as volcanic features - I saw as old volcanoes, as kid, many moons ago...

I can't help but think that volcanic activity, even very, very minor in size and type, has occurred later than the 5000 or so years currently thought to be the last notable volcano activity in Victoria/South Australia (and perhaps even elsewhere in Australia).

Regarding Bass Strait, we used to have a house on Philip Island and would travel all over the place, photographing scenery, and I always had a strong feeling about the volcanic connection with the Strait, the islands and the vast regions near San Remo and even further SE to towards Wilson's Prom. I am still drawn to these regions (particularly near San Remo) and may move back down that way - amongst the rolling mounds/hills down there. I was always fascinated with the land formations/geology down there.

Cheers, Duck.

Wifey took me along to see san andreas movie last night. Realism was never going to be a strength but effects were. Two highlights , first was seeing s waves rolling through san fran flipping the entire bay area about 30 to 40ft up each wave ( outstanding that ) , the 2nd was the actress who plays the daughter , not sure who she is but oh boy , she gave me an M5.

Hi Kazz63.

It is interesting. The undersea mounds (volcanic) can be made out on satellite images. I reckon these sea mounds are not too distant cousins of some of the volcanic provinces which run up/down the eastern regions of the Australian mainland.
These are the sorts of reports (discoveries of undersea volcanoes), which I mentioned quite a while ago will start to become news and noted.

I will be interested in seeing what other info the scientists present in the future about Australia's volcanic regions.

Cheers, Duck wink

Hi Knot.

Yeh, I have often wondered what the heat produced from 'thermals' in the oceans does or contributes to warm pools traveling around the oceans, and how it may affect localized or event distant climate.....?

Cheers, Duck.

Hi Knot.

Yes it is all very interesting. Volcanoes can cause climactic changes. Other natural occurrences also can cause such changes. The number of volcanoes on land and under-sea must be having some sort of effect on parts of the Earth's climate...?

Cheers, Duck.

Here's the full text from the alert I received earlier re the undersea Caribbean volcano:


Potential Kick ’em Jenny Activity (Orange Alert) and the Associated Tsunami Threat Statement from the Pacific Tsunami Warning Center and US National Tsunami Warning Center

Kick 'em Jenny is an active submarine volcano or seamount on the Caribbean Sea floor, located 8 km (5 mi) north of the island of Grenada and about 8 km (5 mi) west of Ronde Island in the Grenadines at roughly 12.30° N, 61.64° W. Its summit is approximately 200 m (600 ft) below the surface of the ocean.

What?
The Seismic Research Centre (SRC) of the University of the West Indies has issued an Orange Alert for the underwater volcano Kick ’em Jenny1. An Orange Alert means “Highly elevated level of seismic and/or fumarolic activity or other unusual activity. Eruption may begin with less than twenty-four hours notice.”

Why?
Instruments monitored by SRC recorded strong, continuous seismic activity from the volcano between 1:25 am and 3:00 am, local time, July 23, 2015 suggesting than an eruption could occur with less than 24-hours notice. Signs of elevated seismicity (earthquakes) began on July 11th and continue to the present.

What is the tsunami threat?
An undersea volcanic eruption can displace the overlying seawater, generating tsunami waves. The amplitude of the waves and area threatened depends upon many factors including the size, depth, and nature of the eruption. Should a tsunami occur, waves would reach Grenada within just a few minutes. If the tsunami were large enough to expand further, it would reach St. Vincent within 10 minutes, Martinique and Tobago within about 30 minutes, and Barbados within about 40 minutes. A very large tsunami could reach the northern coast of Venezuela to the south and the Leeward Islands and Puerto Rico within an hour and a half. Any tsunami hazard would be confined to the Caribbean region.

What is being done?
Kick 'em Jenny activity is being closely monitored by the SRC and further updates will be issued by SRC as more information becomes available. The Pacific Tsunami Warning Center and US National Tsunami Warning Center are also following the situation closely and will be monitoring seismic and sea level data from the nearest seismic and coastal sea level gauges. Should an eruption be confirmed and/or tsunami be detected they will issue appropriate messages to their respective areas of responsibility in the Caribbean region. Citizens are reminded to follow all instructions from their local emergency management. Some rules for tsunami safety and response can be found at: http://www.nws.noaa.gov/om/Tsunami/
SRC recommends that vulnerable communities be advised of evacuation routes and transport be put on standby. SRC indicates that local radio stations in Grenada, St. Vincent, Barbados and Trinidad have been placed on alert. SRC recommends that the public listen to their local radio continuously for updates and visits the Seismic Research Center website if possible..SRC instructs that shipping vessels should stay outside of the first exclusion zone - 1.5 km from the summit of Kick ’em Jenny and that non-essential shipping, such as pleasure craft, should stay outside of the secondary exclusion zone – 5 km clear of the summit.

There's been a big volcanic eruption of Mt Manam in PNG a few hours ago with the ash cloud up to 65,000 feet (20km) high.

There's already an aviation colour code red (the highest) on it.

Wouldn't be surprised if it caused some disruptions and/or diversions to flights whose routes lie near the area and maybe some spectacular sunsets in the region.

Below is the output from the HYSPLIT ash dispersion scheme showing where the higher concentrations of ash could spread to by Sunday morning - this assumes a worst case scenario though (continuous eruption for 48hrs and no ash reduction) so the actual outcome might be different:

It looks like Cotopaxi in Ecuador could be gearing up for a major eruption. The government there has declared a state of emergency for the whole country. If this does go bang and the aerosols ejected into the stratosphere are sulphur rich this eruption has the potential to have global impact on temps, given how close to equator the beast is. This could bring more snow to our Alps or is too late for impact. What do others think?

Hi all, Cotopaxi is a worry, being one of the largest volcano's around & has had a very long repose . Has a history of VEI3 -VEI5 eruptions.
Seems to be a fair bit of activity around the world atm !

Hi all.

Just thought I'd drop in here to add a couple of links to interesting articles regarding volcanoes in NZ and off the coast of Oregon/Washington in the U.S..

Rotorua Geyser erupts after 35 years of inactivity By Moana Tapaleao 2:59 PM Wednesday Sep 9, 2015

I remember filming the geyser just before it stopped being active...did I jinx it smile It is an interesting one to see and the bubbling mud pools are fascinating too.

You may remember I pointed out some of the under-sea volcanic mounds (I was drawn to) in this general location (U.S. and Canada) quite a while ago. See the following report about an eruption west off the coast of Washington/Oregon recently (April 2015)...

Axial Seamount eruption of April 2015 confirmed, US Posted by Elena Ugrin on September 11, 2015

To catch up with other current volcanic activity, have a look at the Volcano Discovery website

Cheers for now, Duck.

Hi logansi and all.

Here are some interesting articles;

World's longest continental volcano chai...tember 15, 2015

Mexico’s Colima and Popocatepetl volcano...tember 12, 2015

Notice how many volcanoes have been going off in recent times, and near some of the locations where there is quite concerted EQ activity (generally near plate edges)? Interesting to say the least.

Japan's volcano activity is not surprising. This is one of the regions with some solid plate activity. Watch the U.S. for sneaky volcanic behaviours (even if minor). Not only will known volcanoes (some of them in various spots around the planet) will show and are showing activity, some more volcanic behaviours may crop up in locations considered 'dormant' or 'extinct' in the future (globally).

Cheers, Duck.

Was watching a documentary on ABC some time ago (this year), about the mechanisms governing one of Africa’s Savanna Volcanoes. Apparently there is a huge plume of upwelling magma, on the continental scale, creating changes in the surface landscape of Africa. In due course (on the geological time scale) this plume is said to “sink” Africa, forming inland lakes and eventually seas in the far future.

I can’t find any specific references to this information, but there probably are some if one knew where to look [I’m not an expert in this field].

I think, judging by the documentary evidence, it's having an impact now -- some of the wilder beast herds are on a massive scale at a very specific area downwind of the Volcano in question, because whatever the volcano is emitting (however regular/irregular that may be) it's impacting the chemical composition of grasslands (and presumably soils) in that location making them very fertile and suitable for grazing.
