Rumblings on the Edge of Yellowstone National Park
Thursday, 06 January 2011 09:18
A year since a swarm of earthquakes hit an area right outside Yellowstone National Park, sensors have detected a series of small (under 1.7 on the Richter scale) micro earthquakes in roughly the same area over the last week. Is this just a burp, foretelling of another swarm, or more?
I think the chances are about 0.001%, you probably have more chance to see a flying pig.
oh... and the last full scale eruption was what... 640,000 years ago? You are probably just better off forgetting about this place for the rest of your life because it will never blow, probably for atleast another 100,000 years or more.

If that super-volcano pops, life itself would get very interesting. It wouldn't be pretty.
On the other hand, we wouldn't have to deal with that silly global warming debate any longer.
