Possible new volcanic eruption in Iceland

Unread postby dohboi » Mon 18 Aug 2014, 16:24:15

Possible volcanic eruption under a glacier in Iceland .....

http://www.theguardian.com/world/2014/a ... -to-orange


Bardarbunga is Iceland's largest volcanic system, located under the ice cap of the Vatnajokull glacier in the southwest of Iceland. It is in a different range to Eyjafjallajokull.



"And there is really a huge earthquake storm at the moment. Iceland met office monitor earthquakes on the following link. http://en.vedur.is/earthquakes-and-volc ... rthquakes/

This could get interesting for air travel in Europe if winds are in the right direction."

"It could also seal the fate of the Arctic Sea Ice, if not this year then possibly in the coming years, with all that extra ash landing on the MYI."

PS:

Icelandic Met Office has moved the warning level for air traffic up to Orange level (see here). GPS measurement have confirmed magma movements inside Bárðarbunga volcano and this movement is fast.

Say it three times: Bartharbunga, Bartharbunga, Bartharbunga!

In Icelandic, ð represents a (usually apical) voiced alveolar non-sibilant fricative [ð̠],[3][4] similar to the th in English "them"

dohboi,

I thought Bartharbunga was the Italian actress who used to arrange parties for Berlusconi.

So much for BBC Online as a news source.

Just saw a special on volcanoes: on any given day about 20 volcanoes are erupting to some degree.

Yeah, but how many are called Barthabunga! (Or Bardabunga, or however the hell those damn Icelanders pronounce their crazy f'n language! :lol: )

Dohboi - Actually their language isn't that complex. Years ago an Icelander explained it was something of a national prank: they intentionally made up unpronouncible words just to screw with the rest of the world. I believed him since I'm sure Mr. Sthritaichuinasm Figauegertuity would never lie to me.

I was kind of kidding. I'm kind of teaching ancient Icelandic to an eager and sharp student, who, however, is now willing so far to put in the requisite time to learn the finer points. Lot's of great lit!

Here's another piece on this potential eruption:

The risk of an exploding glacier is heating up in Iceland

Will lava soon hit glacier ice, unleashing an explosion that would spew ash and steam high in the atmosphere?

The Icelandic Meteorology Office (IMO) thinks that the probability of such an event in their country has increased. Through August 16, 2014, the risk level had been at code green – a “background, non-eruptive state.”

The IMO has upgraded the risk twice in the last two days, on August 17 to code yellow, and early in the day on August 18 to code orange, indicating that a “volcano shows heightened or escalating unrest with increased potential of eruption.

Bárðarbunga pronounciation?

Emphasise first vowel. á as 'ow' in owl. ð as th in Thine. u as oo. g as in gun. So b-OW-r-tha-boon-ga. Rolled R, like in Spanish or Swedish. “bOWr-thahr-boonga” gets you pretty close to the correct pronunciation. (Stress only the first syllable, and use an unaspirated th as in “this”, not an aspirated th as in “think”. For extra credit roll the r at the front of your tongue as in Spanish.)

Bárðar was one of the early viking settlers of Iceland and is considered the volcano's namesake, bunga means bulge or bump. So the name of the volcano translates to Bárður's Bulge. (We're talking anatomical here - i.e. ...hung like a horse... Bárðar, what a well-endowed bulge ye have)

Ah Iceland's at it again. Who needs a military when you have a volcano that can cripple the aviation industry of Europe?

Purely hypothetical question here. It's not even a suggestion, but rather a remotely possible connection between rising surface air temperatures, thawing permafrost, and subterranean magma flows/ejections. Bear with me.

We all know that surface temperatures are rising. We all know that permafrost is thawing. Most of us have heard/read that the Antarctic continent is melting, not from increased surface temperatures, but from increased temperatures in its underlying magma chamber. We've also witnessed a few hefty volcanic eruptions lately in Sumatra, Chile, and even New Zealand, and now, too, in Iceland. Pair that with the literal melting of asphalt roads inside Yellowstone National Park recently, and a near doubling of the known size of that supervolcano, and it all gets that little mousewheel churning inside my head. As the surface temperatures rise, thus melting the permafrost, that activity opens up new vents for subterranean methane, thus releasing pressures that have existed within the earth's crust for millenia. That release of pressures, therefore, theoreticaly can have unknown effects on the next layer down within the earth's crust, where the magma flows. So, adding all these pieces together, is it possible that global warming could unleash an increase in volcanic activity and earthquakes, along with increased air surface temperatures? Could we be heating up the earth, both inside and out?

Yes.

Locally, at least--no question about it. It happened on Iceland already, long ago. This from expert and author on the subject, Bill McGuire:

Twenty thousand years ago, Iceland was entirely covered by a layer of ice that averaged close to a kilometer in thickness. Around 15-16,000 year ago, planetary warming triggered rapid melting of the glaciers, reducing the load acting on the volcanoes beneath and on the underlying asthenosphere.

By 12,000 years ago unloading was sufficiently advanced to trigger a spectacular response. Over a period of 1500 years or so, the volcanic eruption rate jumped by between 30 and 50 times, before falling back to today's level.

This volcanic rejuvenation was in part a reflection of the release of magma held ready and waiting, within and beneath the volcanoes themselves, but mainly testament to a huge increase in the supply of fresh magma from deeper within the Earth. Such was the load reduction due to the rapid loss of ice mass, that the depressed lithosphere quickly bounced back by as much as half a kilometer, dramatically reducing the pressures in the asthenosphere and triggering a 30-fold jump in magma production.


(Thanks to ASLR at neven's forum for this quote.)

You might want to check out his book:

In his latest book, Waking the Giant,he argues temperature change brought about by global warming could release pressure from melting ice caps (through post-glacial rebound) and trigger quakes and volcanic eruptions...

Don't forget that Iceland is sitting on two spreading tectonic plates and most of the volcanic activity is magma filling in the "void" caused by the spreading.

OMFG! Fun times, indeed! I suppose it's also entirely possible that Yellowstone will erupt in North Dakota due to all of that fracking activity distrupting the pressures of the earth's crust 500 miles west of where that supervolcano is actually located. That volume of natural gas and an underlying supervolcano would make for one heck of a made-for-tv disaster movie! Volcano on the High Plains! Run southwest! As fast as you can!

Sounds like a screenplay Timo. Graeme is the under appreciated envrio who warns the townspeople of the impending doom. And ROCK is the evil oil exec. Then the scientist is killed by the oil cabal. And Graeme rescues ROCK (because Graeme is more moral) And everybody else runs to Mexico . . . except the border is closed off . . . and the Norto Americanos die.

The simple people of Sudo Americanas, the campesina and campesino, say 'told you so' and 'no fracting here' and the 'God will fling arros con pointos and you will die, Norto Americans'

Norto Americanos are generically referred to as Gringos! That goes for anyone with pelo rubio, and pelo rubio generally includes everything other than pelo negro. Where does Pops fit into this screenplay? And Tanada? MBS sounds like the doctor who tries to save everyone from the Big Boom. Doboi, aka Dough Boy, is the baker who takes advantage of the fire in the sky to make bread. Maybe Pops is the sedate old man who simply resigns himself to staying put on his lake, and putting on a happy face while we all die. Tanada is the rogue scientist who tries to figure out a way to lower a nuclear bomb into the earth's crust to kill the entire volcanic eruption. Ibon is already safe, tucked away in his rainforest in the clouds. He communicates with Agent R11 over ham radio. Agent R11 is the secret negotiator who tries to get people past the Panamanian Security Forces guarding the canal. We're all set. I'll be the director.

Isostatic rebound might have effected volcanic activity over the shot time frame mentioned. But Iceland is part of the Mid-Atlantic Ridge which has been an active source of volcanic activity for hundreds of millions of years. As far as the Yellowstone caldera it has existed and periodically erupted more millions of years. The forces behind this activity originate hundreds of miles below the surface. The huge magma chamber below Yellowstone continues to be active and occasionally still causes some uplift as it periodically swells. The recent oil/NG drilling activity occurs within the first couple of miles. The amount of energy involved in such activities is grossly insignificant compared to the forces that determine events at Yellowstone.

But yes...makes great fodder for sci-fi movies.

Don't forget the forces needed to move North Dakota to somewhere 500 miles west of Yellowstone.

Some creative minds at work(?) here.
