+joc Posted December 12, 2013 #1 Share Posted December 12, 2013 It’s the awe-inspiring pride of the United States – and it harbors a deadly power that could kill us all. Yellowstone National Park is pristine wilderness, full of scenic landscape and iconic hot-pools and geysers that attract tens of thousands of visitors every year. But it’s what lies beneath that has scientists scurrying. We’ve long known that Yellowstone is merely the skin on top of a supervolcano – a giant pool of magma sitting just under the Earth’s surface. Exactly how giant has been the subject of much speculation. Until now. 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. Link Link to comment Share on other sites More sharing options...
