    What's the point? Not like we can do anything about it. Now if it were an asteroid it'd be a different story, we could just send Bruce Willis and Ben Affleck to blow it up.

    Anyways. On topic, ther'es really nothing we can do is kiss our butts goodbye. You can't stop a Volcano.

    http://en.wikipedia.org/wiki/Yellowstone_super_volcano

    That’s very interesting, I remember seeing a doco about supervolcanoes a few years ago, the Discovery Channel highlighted six known supervolcanoes: the Yellowstone, Long Valley, and Valles Caldera in the United States; Lake Toba, North Sumatra, Indonesia; Taupo Volcano, North Island, New Zealand; and Aira Caldera, Kagoshima Prefecture, Kyūshū, Japan.

    The first super-eruption at Yellowstone ejected into the atmosphere 2500 times more volcanic material than the Mount St Helens eruption of 1980; the ground beneath Yellowstone could hold more than 25,000 cubic kilometres of molten rock; an eruption could send as much as 2 billion tonnes of sulphuric acid into the stratosphere; and the death toll from a Yellowstone super-eruption would top 1 billion people. And that's just for starters.

    I understand that knowledge of Supervolcanoes is relatively new to science.

    This thread probably belongs in Earth Science I think.

    How could it be 1 billion people?
    There are only around 350 million people in the US and it's not like they are all going to drop dead the second it erupts.

    Yeah The thread can be moved up there, i just find full scientific threads lack personal opinion, which can mean allot, esp with a smart audience.

    i think they were referring to world wide, not just American

    And imagin if something caused them all to erupt

    The effects would be world wide, acid rain, crop failure and a mini nuclear type winter minus the radiation.

    Yellowstone has erupted three times, 2.1 million years ago, 1.3 million years ago and 640,000 years ago, a cycle that suggests the next eruption is due.

    Susan Orr who produced the doco (Nowhere to hide) says:
    "The reaction to this information, is generally disbelief. And understandably so," she adds. "Two years ago, when this film was first suggested to me, I didn't know what a supervolcano was and once I found out my reaction was the same. Why don't people know about these things? This is something we should all know about."

    Well first off nothing would cause them all to erupt. And second, the part of the explosion that would have any sort of lethality ends inside of the united States. sure other countries may get some wierd weather, but it won't be lethal at all. It's be the US that is by far the hardest hit.

    But remember that the next eruption being due is give or take anywhere from a thousand, to ten thousand, to even a hundred thousand years. So I wouldnt be sitting on the edge of your seat waiting for it to happen.

    Actually there just might be a way to relieve the pressure in the center of the volcano by using a tunneling machine to make a tunnel to the magma to relieve the pressure of building magma before it erupts.

    Because:

    a: it may have shot its load already.

    b: examining event from millions of years ago is not exactly as simple as saying you know for certain what actually DID happen.

    but for real, how would we even be able to begin cleaning up the mess?

    But there are other effects to consider, and weird weather alone can be a killer.

    History suggests that's probably a bad idea, unless you get in shortly after the previous eruption.

    Generally, removing weight removes pressure, and makes it easier for a volcanoe to erupt (consider the 1980 eruption of Mt St Helens, for example).

    Also, consider that a Volcanoe is what you get when you have a tunnel connecting the surface to a magma chamber.

    Evidence would suggest otherwise.
    Yellowstone is located above a hotspot, hotspots are believed to draw their power from deep in the mantle, near the boundary between the mantle and inner core.
    There is still a substantial amount of heat under Yellowstone, however, there is some evidence to suggest that the magma chamber directly under the caldera might be cooling, however, this is far from being indicative of having 'shot its load'.
    The mantle plume that powers yellowstone has a diameter of 1000km, is currently centered under Dillion, Montana, connected to the Yellowstone hotspot by an 80km wide conduit - the implication being that if it has indeed 'shot its load already' which I highly doubt, then it may simply mean that the hotspot is shifting it's focus.

    From a 2009 article (not quite what I had pictured based on what I had read elsewhere, but).

    Finally found what I was looking for - it shows the relationship of the Magma resevoir under Yellowstone that's been feeding the eruptions to the plume imaged above:
