    The supervolcano that lies beneath Yellowstone National Park in the US is far larger than was previously thought, scientists report.

     

    A study shows that the magma chamber is about 2.5 times bigger than earlier estimates suggested.

     

    A team found the cavern stretches for more than 90km (55 miles) and contains 200-600 cubic km of molten rock.

    The findings are being presented at the American Geophysical Union Fall Meeting in San Francisco.

    As the cycle is estimated at around 700,000 years and its about 640,000 years since the last major eruption I think CM you might be safe for a little while longer. But then we do only have two data points to compare it with so it could go soon!!!!

    Don't worry we'll catch you in the uK as you fly over.

    Doesn't work like that though. You can't set a clock. We would also expect some minor eruptions and there hasn't been any either.
