No farm land available and once all that ash gets into the atmosphere it would travel around the world and block out the sun. Sort of like a nuclear winter for around 10-20 years global wide. I think if it blew while I was alive, I just as soon be standing right next to old faithful and have nothing to worry about the aftermath.

    So you all can keep score at home, the eruption of the caldera is preceded by a slow inflation of the magma bubble that eventually reaches a point where the earth cracks open and then collapses, spewing the magma and ash. The current belief is that the elasticity of the mantle above the caldera is such that the rising dome (it is rising a few inches a year) will reach an elevation of about 1 mile higher than its current position before the ground cracks under the stress.

    So... 1ft of elevation takes ~ 4 years so 1 mile elevation rise will take ~ 21,000 years, give or take. There will be plenty of warning.

    Re: Beneath Yellowstone, a volcano that could wipe out the US.

    There are six known supervolcanos worldwide. Not to mention the Ring of Fire which could see multiple volcanoes erupting. We do have a better sense of what is happening with Yellowstone warning wise these days. We've developed tech that allows us to see the size, shape and movement of the magma chamber below.

    And then there are precipatating events, like the geomagnetic reversal. Our electromagnetic field reverses from time to time. In the past this has happenned roughly every 450,000 years or so, but it's been 780,000 years since the last one (though we had a minor one 40,000 years ago). We are a tad overdue. This could easily cause one or more of the supervolcanos or the Ring of Fire to erupt.

    A team from the University of Utah have told the American Geophysical Union Fall Meeting in San Francisco that Yellowstone’s magama chamber is 2.5 times larger than previously thought.
    It is an underground cavern measuring some 55 miles by 20 miles and containing between 125 and 185 billion cubic miles of molten rock.
    If it blows it will wipe out America – and have enormous impacts on the rest of the world.
    The university researchers described their discovery as “astounding.”

    Old news and it will be the planet that is wiped out. Also it is due for an eruption, not 500k years from now. Guessing the NYPost is having a slow bash Obama day...

    I think if Yellowstone did erupt, it would throw mankind back into the stone age for those who survived.
    This Reform Party member thinks it is high past time that we start electing Americans to congress and the presidency who put America first and their political party further down the line. But for way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.

    Actually, that is one of several supervolcano calderas that exist in the world. Any one of them could be a major problem, not only for the regions they are located in, but for the world in general. Think nuclear winter here.

    Declining underground mine insurance? Good idea.
    Declining liquid hot magma insurance? Maybe not the right call.

    Geological time eventually meets historical time. And I wouldn't put much stock in that 500k figure, could easily happen tomorrow we're finding out. There are certain crystaline conditions that form presaging an imminent eruption (in historical time). Studies are being actively done now on Yellowstone because the magma chamber has been acting 'wonky'.

    Somebody might want to check the math on this.

    Sorry shrub, that has already been pointed out. Of course it was to be 50,000 years.
