Around the end of '08 beginning of'09 there was tremendous seismic activity at Yellowstone. Back a few months ago there was another set of quake swarms, that the USGS says was larger than last years.

The floor of Yellowstone Lake had been lifting in the past. What is happening now, I'm not sure.

Though not in a subduction zone, should something start this thing up, it could make an eruption in Iceland seem like nothing more than a burp.

Yellowstone has “end of civilization as we know it” capability certainly.
