I read that the caldera under Yellowstone was several hundred times bigger than the one at Krakatoa, which erupted in 1883 and caused an explosion equivalent to 200 megatons of TNT.
Be very afraid.

Yellowstone volcano goes BOOM?

Dang, Hockey. I would have figured you more for a "look at the pictures" kind of guy.
Actually, the Yellowstone earthquake swarm is mimicing a similar swarm at Mt. St. Helens. They figure it is the result of recent subduction activity in the Juan de la Fuca (sp?) plate under the North American plate. When you get that kind of tectonic plate subduction, it generates a lot of heat (friction). That causes more melted rock which causes more magma which causes magma shifts in local magma chambers.
There is, however, a competing theory. Tracey's recent visit probably raised the local testosterone levels and consequent collective temperature levels enough to increase the magma and global warming in general.

I'll take that as a compliment. Thanks Art. :kiss2:Now that you mention the plates, I remember our guide saying something about that and if they started moving.
