    That was just tried in a geothermally active area in northern Europe. The person who runs the company is on trial for the damage he caused when it triggered earthquakes... and his project was far less ambitious and on a tiny scale in comparison to what would need to be done at Yellowstone.

    Triggering real earthquakes, much less the type of problems that the far more massive scale attempts needed at Yellowstone would cause, seems an exercise in mass suicide.

    Even if you can't use all the energy, there must be some way to bleed it off.

    Sure; just turn it into a big geothermal energy farm. Run a bunch of pipes (tubes?;-) down to carry the heat to power generators. The current estimates are that the heat from Yellowstone could pretty much supply electricity equal to the world's current usage for several centuries. Of course, distribution to areas outside North America would be problematic. Also, we don't know how fast the heat sources might be replenished from below, so we really know how many centuries (or millennia) it might last.

    Well, if the plume is connected to the core mantle, as scientists are now speculating, then it will last "forever"

    Of course, (1) it's supposed to take the Earth billions of years naturally to cool, so it is unlikely we could ever cool Yellowstone. (2) Though cooling it's surface may slow things down, it may also create a more massive explosion when it happens, (3) we are ill equipped to deal with that type of magnitude of heat, magma and pressure, and finally (4) cooling the "whole thing" if it does indeed include the core mantle, would be the end of life on Earth anyway.

    I for one vote to leave it alone - at least till we have better technology and an idea of just how deep it is...

    Actually, I am talking about the explosive force of the last big eruption in comparison to the explosive force of nukes. I am not talking about the energy contained in the system.

    The energy contained in the system is far more vast... and if current speculation and theories are correct (that the system is actually connected to and thus fed by the core mantle itself) then the energy in the system is too vast for me to even speculate about.

    Smith says "it wouldn't surprise me" if the plume extends even deeper, perhaps originating from the core-mantle boundary some 1,800 miles deep. "

    And here is a question... considering the caldera alone is somewhere around 2000 square miles, and the TOP of the hotspot stretches over 7,500 to 10,000 square miles (with hundreds of thousands of cubic miles worth of it stretching downwards - ASSUMING it does not connect to the core mantle - in which case it's enormous.

    So... the question... how do you cool the top of such a hotspot when it is thousands of square miles big?

    Sorry, I really did spend a lot of time researching it. Scientists in this field think trying to cool it, trying to relieve pressure or anything similar is either useless, senseless and/or very dangerous.

    (2) We do have a very tight food supply in many countries - some have far less supply than demand and rely on bartering with other nations. As for this country, though we produce enough to feed the whole world, all of those areas will become infertile. The majority of food (plant or animal) producing areas in this country sit quite nicely in the area that will be devastated by a major Yellowstone eruption.

    (3) The fallout and drops in temperature will hamper the entire rest of the world's food production capabilities - after reducing ours to 1/10th of what it is from direct effect.

    (4) Unlike in past similar eruptions (Toba, being the only one), the population of the Earth has increased by a factor of around 7 thousand. For instance, in 70,000BC (around the time of Toba) the world had an estimated less than one million people. The county I live in has 3 times that - Nassau county has 3 times that and could fit in the volcano's caldera (ie: this tiny land area has 3 times the world population during the time Toba went off). Manhattan Island, a mere 15 or so square miles, has over EIGHT times the world's population of that time.

    That means a 20% mass extinction event would lead to around 1.3 BILLION deaths. Today, even a small percentage is a massive amount of people.

    Now, in the US...

    When Yellowstone went off 640,000 years ago, there were ZERO humans affected...

    Why you might ask? Because there were NO humans.

    Mitochondrial DNA and fossil evidence indicates that modern humans originated in Africa about 200,000 years ago.

    Today, such an eruption would mean the US (what's left of it) would have to import all (or to be more accurate, somewhere near 99%) of it's food, and that would be from countries that were also severely effected by the aftereffects.
