#1 How large an explosion are they talking about here? A crater a couple of thousand feet in diameter sounds huge, who cares if its technically a volcano or not.

#2 Yellowstone sits in the two craters of two super volcanic events, one of which may have been the biggest volcanic explosion ever. The whole park continues to tilt as the dome grows, and a new eruption is going to occur, though in the timeframe of the tens of thousands of year or so.

The United States is under geologic threat from the many volcanoes along the Pacific coast that are known to be active, the New Madrid fault in the central Mississippi Valley, the San Andreas fault in California, and the Yellowstone Basin volcano. The two fault zones are both overdue, statisticly, for major earthquakes. Several of the Pacific Coast volcanoes are near to their mean eruption periods. Yellowstone is perhaps the least likely of the four for the immediate future.

I believe Ms. Morgan is underestimating the force of a steam explosion, whatever else the geology is telling us.

#3 Chuck, you omitted the Long Valley Caldera under Mammoth Mtn in California. Carbon Monoxide seeping from the ground and volcanic byproducts as well as extensive tremors indicate the same kind of activity there

#4 oops - found it in your volcano link.

#5 Frank, Long Valley / Mono Lake, in my generalization, fell into the category of Pacific Coast volcanoes. It does, however, pose as significant a threat to Los Angeles as does the San Andreas Fault. And it is due, as well.

#6 Yellowstone is pretty much one big "shield" type volcano. That's why there's so many hot springs, geysers, etc. etc. Dangerous suckers.

#7 Thanks for those links, Chuck. I now vaguely remember a show on Dicovery or TLC about that mentioned this about Yellowstone.

#8 Maybe a stupid question, but I wonder if the energy can be diverted by using this as a geothermal power source?

#9 Friend of mine used to be a high-ranking vulcanologist in USGS. His comment to me one evening at a stamp club meeting was "don't move to such and such a place - it's not safe." We were talking about moving to Idaho. Apparently, there's another hot spot associated with the Yellowstone area to the northwest - possibly a secondary hot spot or vent. There's also indication that the eastern Rocky Mountains are overdue for a major event, either vulcanology or earthquakes. Makes me feel so comfortable sitting here in Colorado Springs, also known as "crosshairs city".

#10 Okay... (scratches Colo off list of potential places to move to when US economy picks up)

So many things to consider when choosing a home! Not being vaporized, vulcanized, jihadized, irradiated, PC'd, or taxed to death - any others I should take into account?
