Isn't it About Time for Another Iceland Volcano? (Bárðarbunga dude)

On April 15 we posted "You say Volcano, I say Eyjafjallajökull (Volcano could mean cooling, acid rain)":
Here's the BBC's Guide to Icelandic Pronunciation. Pity the poor newsreaders.

As best as I can make out it's something like:

Ewe-gotta-be-fcking-out-'o-yer-skull

Which ended up being fairly popular.
Répétez?
Here's the latest, from FromTheOld:

Iceland's Bárðarbunga volcano shows more activity lately

Sunday, September 26, 2010 - 14:21

Bárðarbunga is a powerful stratovolcano in Iceland and is located under the ice cap of Vatnajökull glacier. With a massive high of 6591 feet above sea level that makes it the highest mountain in Iceland it also makes for some powerful volanic activity when it erupts.
Iceland's Bárðarbunga volcano is said to erupt every 250-600 years if scientists are correct. What many dont know is that the most powerful volcano eruption on earth happened at Bárðarbunga some time ago....MORE

HT: ZeroHedge, prop traders and volcanologists.

That last statement re: most powerful is incorrect.
The eruptions that created the Yellowstone caldera were a bigger bang, something like 2000-2500 times as powerful as the Mt. St. Helens eruption in 1980.

Here's a list of some other biggies.
