My BS meter is getting warm...As the continent slides over the Yellowstone hotspot, the former caldera cavities can be seen in a line going into Idaho. Judging by the distance between them and knowing the rate of continental drift, the eruption cycle has been estimated at 600,000 years.

When
Toba blew 75,000 years ago, only 2-5,000 people worldwide survived. The death from the 'nuclear winter' effect from Toba can still be seen in the human genes.
BTW, even the Mormons with their one year 'stash' of food will not survive.

Yeah, I know. That was after the Park Service had a fit about it. I don't think anybody actually did do that, but they were afraid somebody might, because they'd already had other incidents.

Cool site. Here's a quote from one of the links there:
There is no evidence that magma beneath the enormous Yellowstone caldera is directly involved in the recent changes at Norris or Nymph Lake. Though magma as shallow as 3-6 miles beneath Norris does provide the heat for the geothermal system, the current activity is very unlikely to reflect magma ascent or increased likelihood of volcanism at Yellowstone Park. If magma were to rise to shallow levels beneath the ground it would be accompanied by intense swarms of local earthquakes and extensive displacement (deformation) of the ground surface around Norris. Thus far, caldera-wide seismicity and ground deformation have remained at typical background levels beneath Yellowstone and Norris.

Oh, please! What a crock of used food. This guy never heard of the inverse-square law Yes inverse quare applies ... but they will still die. IF this thing blows .. cancel the US.

Must be a lot of hits right now on Yellowstone's web site. It's not responding. . Maybe it's halfway to the moon and the noise hasn't reached us yet. :^)

"There's a site in I believe Iowa or Kansas in which hundreds of large animals such as camels, rhinoceros, etc were found buried in many feet of ash." It was six feet deep in Nebraska the last time it blew.

What is a supervolcano?
The term supervolcano has no specifically defined scientific meaning. It was used by the producers of a British TV program in 2000 to refer to volcanoes that have generated Earth's largest volcanic eruptions. As such, a supervolcano would be one that has produced an exceedingly large, catastrophic explosive eruption and a giant caldera. Because Yellowstone has produced three such very large caldera-forming explosive eruptions in the past 2.1 million years, the producers considered it to be a supervolcano.
How many supervolcanoes are on Earth and what are some examples of supervolcanoes?
Because there is no well-defined minimum size for a "supervolcano," there is no exact number of such volcanoes. Examples of volcanoes that produced exceedingly voluminous pyroclastic eruptions and formed large calderas in the past 2 million years would include Yellowstone, Long Valley in eastern California, Toba in Indonesia, and Taupo in New Zealand. Other "supervolcanoes" would likely include the large caldera volcanoes of Japan, Indonesia, Alaska (e.g. Aniakchak, Emmons, Fisher), and other areas.

I guess we should hope the park service people are better informed than the CIA and FBI.

I'm not saying that the area is not geologically interesting, I am saying there will be a buildup of quakes above background levels before the thing blows.
Frankly, if you wanted to worry about a gelogic event which could occur without warning and kill millions, start sweating about another major quake (also 'overdue') in southern Missouri.

But why has the park service closed Norris?
And what about my trout?

Or you're just unfamiliar with what has happened the previous times Yellowstone has blown. Such an eruption now would have a major worldwide effect. It would dwarf the volcanic explosion in the Mediterranean in the 2nd millennium BC and that affected the entire planet.

Its in Eastern Nebraska, I cant recall the name of the town though.

I think that's how a lot of the animals in Texas died the last time Yellowstone blew, from lung desease.

I'm not sure, but wouldn't it be something like inverse-cube law here?
Energy can spread out vertically as well as horizontally. Thus, the energy density or pressure wave at 20 miles would be 1/(2 to the 3rd power) or 1/9 of the values at 10 miles from blast source.
(There might be some edge effects away from the blast due to the massive earth. That might might make the blast effects slightly higher than predicted by inverse-cube, but still way below inverse-square.)

You know what's really disturbing? The fact that an eruption of that magnitude would probably neutralize our land and most of our air based nuclear deterrent...
