I looked to see if Katla was a supervolcano, like Yellowstone. http://answers.yahoo.com/question/index?qid=20100417003940AAxFAe4 Apparently not. Or should I say: apparently not yet :( Speaking of Yellowstone: The last full-scale eruption of the Yellowstone Supervolcano happened ~640,000 years ago and ejected a cubic kilometer of rock and dust into the sky. This does not imply that another one is overdue, but could it be triggered by Katla and/or the other seismic events of the recent months (Haiti, Chile, China, Baja Mexico)? Short answer: probably not. Wiki sez: The upward movement of the Yellowstone caldera floor between 2004 and 2008-was more than three times greater than ever observed since such measurements began in 1923... By the end of 2009, however, the uplift had slowed significantly and appeared to have stopped. In January 2010, the USGS stated they "see no evidence that another such cataclysmic eruption will occur at Yellowstone in the foreseeable future." That pronouncement may actually be a disappointment to a persistent number of Doom-and-Gloomers out there ...
