A volcano under a glacier in Iceland erupted Wednesday for the second time in less than a month, melting ice, shooting smoke and steam into the air, closing a major road and forcing hundreds of people to flee rising floodwaters.
Authorities evacuated 800 residents from around the Eyjafjallajokull glacier as rivers rose by up to 10 feet (3 meters).
Emergency officials and scientists said the eruption under the ice cap was 10 to 20 times more powerful than one last month, and carried a much greater risk of widespread flooding.
"This is a very much more violent eruption, because it's interacting with ice and water," said Andy Russell, an expert in glacial flooding at the University of Newcastle in northern England. "It becomes much more explosive, instead of a nice lava flow oozing out of the ground."

Of course I am basing this on 0% fact, and just my uneducated observation.

Then your methods are in line with Gore’s.
Here is a map of where the current eruption is located in relationship to the March’s fissure event.

I wonder if I could get a Nobel Prize too?
“we are concerned that it could trigger an eruption at the nearby Katla volcano, a vicious volcano that could cause both local and global damage,” said Pall Einarsson, a geophysicist at the University of Iceland’s Institute of Earth Science, Associated Press news agency reported.’’
In fact she was, while in the shower :)
thx much
Yes, the statement is puzzling, and no, I do not have special knowlege on the subject.
No, I cannot explain, ultimately, why a glacier would prevent a volcano from erupting, eventually. Pressure from below merely needs to exceed pressures from above, and in the case of glaciers, only enough heat needs to escape to melt the glacier as you note. No known force can “cap” volcanoes that I know of, except the crust of the Earth (with frequent enough breakthroughs), and glaciers are a poor competitor to the Earth’s crust.
Undersea volcanoes have been discovered recently, that have exploded as deep as 25-30,000 feet below the surface of the sea and have extended debris and lava fields beyond previously suspected or thought possible at these depths...the pressures to be overcome for such blasts are astronomical, and exceed anything we see on the surface of the planet. These volcanoes are true monsters. It may be that undersea volcanoes release more gas and acid forming compounds than those on the surface of the Earth, especially the deepest. We just do not have the money, the sensors, the infrastructure to do much monitoring and data gathering for the most inaccessible and possibly most powerful volcanoes. No giant volcano at great depth has ever been satisfactorily studied, during eruption, that I know of, understandably.
Two-thirds of the world’s volcanoes are undersea volcanoes, and they could be one the most underestimated sources of climate change dynamics.
Planning, taxing, regulating, carbon trading and rationing in anticipation for global warming will prove catastrophic for all on the planet if global cooling or a little ice age comes swiftly upon us, as is suspected of happening now with good evidence. Crop reductions and famine occur almost immediately compared with gradual global warming. All ice ages, as they begin, extreme rain in the spring and fall, thus drowning out crops. In ice ages, the world experienced its highest levels of C02, which in the ice ages stimulated more plant growth on the reduced planetary areas suitable for farming, and assisted in rapid regrowth as the glaciers receeded.
That climate change taxes, carbon futures exchanges, green energy efforts could even equal the Mt. Pinatubo effects alone on climate and the world’s economies is conceptually impossible from the start. There is not enough gold, technology, fiat currency on the planet to do the job.
“Ego-psychosis of functional degree”..to coin a concept, may be at the root of it all, ruling out all reason and firmly establishing political rule via pseudo-science....a clearly foreseeable catastrophe of our own making.
I wonder if I could get a Nobel Prize too?

Well, why not?
Well, maybe not. There is a major criterion you may not meet if you are a FReeper. To be nominated for the Nobel Peace Prize one must be invested in the destruction of the destruction of the US or Western Civilization in general.
Your analysis seems spot-on to me.

From this morning...!
All I get from that link is a shrunken window.
When I enlarge it, the window is blank and says “done” at the bottom left.
Sorry try this one....
Why then not in english:
Eyja-fjalla-jökull
islands-mountains-glacier
The name basically means it is the glacier on top of Eyjafjöll, which is the name of the mountain range, which incidentally means mountains of islands. I am not sure though where the name comes from, but at settlement the lowlands in the south of Iceland were far less than today (having been extended by flooding and rivers carrying mud) and some of the mountains may have been islands at the time. Also the Vestmann-islands are south of them.
I hope your sister is happy with her name, it is a beutiful one ;)
Well this sentence sounds very strange to me, as I don´t see how the lava could flow upwards and go from under the Eyjafjalla glacier to the Mýrdals glacier on top of Katla.
But it is true that in historical times Katla has always erupted sometime (months, to one or two years) after the eruption in Eyjafjallajökull. People have been waiting for a long time for that one, because there has been longer time than usually since it last erupted, some have guessed that some things may have released the pressure from that, f.e. the eruptions in Surtsey and Vestmann islands, and thus delayed it.
An eruption in Katla would threaten a town of roughly 1000 people, who would have under an hour to get away, before the wast flood would sweep the planes which the town stands on.
Tell me about it...seriously do it ;)
I say it all began with the US leaving us, everything has been going downhill since. Or was the turning point when Yoko Ono was allowed to land here and construct here ridiculous “imagine peace” tower of light here. At least since then a crisis after another has ravaged our public and political scene. I am though just fuming my irritation of that constant reminder of socialdemocratic, pacifist thinking that ravages influental power circles in my country, that hinders my view of the stars in the night sky.
We have though been a very fortunate nation and often seemed to be under a blessing, with lot of near misses when it comes to lives saved and such in big events. Hopefully we will be under God´s grace and US protection once more ;)
Thanks, it is a good relief to have something like this in the news instead of that dreary financial crisis report published on monday.
Given the apparent increased tectonic activity they might be afraid of an event like the Laki Fissure eruption in 1783 which killed 90% of the cattle, and 10,000 Icelanders, as well as causing major agricultural disruption in Europe that may have led to the French Revolution.
Thanks g.
It never ceases to amaze me, the vast intellect that hangs out on this site. I learn something new every day.
