Time to ecacuate USA ?

Head to Mexico, Canada, or Mars ?

The good news is that only 30% of it is molten.
Overdue by 40,000 years might indicate that it is cooling off ?

If you drilled for geothermal energy, it might cool it off more.

I find it hard to take a site seriously that links to a bible code site.

What if you weakened the area too much, might that not set it off early?

The Same company that gave us the Space Odyssey mini series has also created another called super Volcano about the eruption of the Yellowstone park Volcano. It will air on the BBC in late January and probably in the US in march.

Yup heard of the island that blewup the impact of the dust in the atmosphere lowering temperatures and making for some of the best sun sets.

I'll get my camera, I like photographing sunsets!

I'm just pleased I don't live in areas like that, though I suppose you get used to it, I like to watch from a distance (a few thousand miles). I wonder what the dust would be like in England if Yellowstone went up?

There is a lake above and the water seeping down cools it via the http://www.yellowstonenationalpark.com/ … tm]geysers.

You could try to release the pressure by tunneling into it with nuclear blasts. Inside a long tunnel complex, the gasses would separate and escape, leaving the hot rock behind ?

The Yellowstone website is a collection of good geologic information assembled by an amateur, I think. One can't refer to a volcano as "overdue" or even as "regular." They are rarely regular and therefore can't be defined as overdue. There is a magma plume rising from the mantle under Yellowstone today. North America is steadily drifting westward relative to the plume. Ten million years ago the plume was under Idaho, which it buried under a few thousand cubic kilometers of basalt. Before that, the plume was under western Washington state. We can roughly predict the rate of drift of North America away from Europe and we can roughly predict the rate magma rises from the mantle. That means we know the volcano will blow roughly every few hundred thousand years. The alternative is smaller and more frequent eruptions, and they happen as well, even at Yellowstone (which has not been volcanically dead for 600,000 years).

All you have to do is go to Yellowsotne Park and hike Mount Washburn--a tall peak near the center of the park--and look at the big tableaus at the visitor's center at the peak, which shows you which peaks and ridges are the old caldera edge. It's hard to visualize from the top of Mount Washburn. But the information is all there, available to any tourists who visit the park. The various eruptions are all mentioned in park publications also.

You must go see Yellowstone sometime in your lifetime; it is truly spectacular. I even managed to see Steamboat erupt (it's mentioned in the website as erupting four times in the last eighteen months, which is the sort of frequency it keeps). But don't lose sleep over the entire park blowing up; it won't happen in your lifetime. There are similar features on the island of Java, and if any of them blow, they'll kill 100 million people in a matter of minutes.

I am trying to fugure out megawatt years that yellowstone would provide in cooling the magma to a solid.

There are a lot of links to geothermal energy.
And could geothermal be the next energy source after the depletion of oil ?

Energy while defusing volcanoes is a viable option ?
