Yellowstone Lake at West Thumb Geyser Basin
"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."
I heard one of the researchers say on the radio that he's pretty sure we'll get plenty of warning as the magma levels rise just before the next eruption. Then again, how much warning do you need for the End of the World?
