The Independent : New geological data published yesterday in the journal Science looks at the behavior of seething layers of molten magma, super-heated gases and hydrothermal liquids underneath Yellowstone National Park. The magma is on the move, and so is Yellowstone.Over the past three years, according to the report, the ground in the volcanic caldera that spans about 925 square miles and accounts for much of the park’s terrain has been rising towards the sky at the rate of almost three inches per year. That is three times faster than has ever been observed before. It raises the obvious question: what is happening under the park? And what might be about to happen?
