Yellowstone super volcano is even bigger than first thought

Yellowstone super volcano is even bigger than first thought - ABC 4.com - Salt Lake City, Utah News: "Here's the short version of what would happen If such an eruption happened today: The explosion and pyroclastic flow (think a tsunami of superheated gas, rock and ash) would level the park and surrounding communities. A few inches of ash would fall on Salt Lake. Add a little rainfall with that ash and some roofs would collapse. No harvest would be possible in America's bread basket. And of course, there would be that volcanic winter lasting years.

Scientists are not only giving us a clearer picture of a super eruption, but also what fuels it. Using a new technique that makes images with electrical and magnetic fields in the earth, scientists at the University of Utah have been looking deep into the earth. Michael Zhdanov, professor of geophysics said, 'Now we can see the unseeable (sic). Now we can see through non-transparent media like rocks.'

The result: the magma plume below Yellowstone is even bigger than first thought. The plume looks like a tilted tornado that extends out under Idaho, Montana and Wyoming. It is made up of hot and partly molten rock surging up into the earth's crust from the mantle."
