OK, so I'm not usually one to worry about mega-disasters. Though I suppose a big hurricane hitting New York qualifies in some senses. However. . .

My brother just got back from a trip to Yellowstone. (Great trip - saw elk, bison, coyotes, wolves, and all sorts of cool geological features.) During the four days he was there, he reports that there were five hundred (500!!!) small earthquakes. Additionally, patterns in the geysers were changing - some becoming more frequent, some less, and some erupting in places where non had been previously.

I've always assumed that an eruption of the Yellowstone Caldera would qualify as a Very Bad Thing but never gave it too much thought.

So, for those who have done more research, is this something that I should be more concerned about? Is this change in seismic activity out of the ordinary? Any thought on what it means?

Jesselp, feeling a bit apocalyptic.
