Yellowstone Super-Volcano is FAR Bigger Than Previously Thought



A new study that will be presented at the American Geophysical Fall Meeting will show that the Yellowstone super-volcano is about two and a half times larger than previously thought.

The University of Utah team found that the magma chamber is some 55 miles long, and it contains up to 600 cubic kilometers of molten rock. If even a third of that volume erupted at Yellowstone we would be facing a global disaster.

Prof. Bob Smith, one of the Utah team leaders said:

“We’ve been working there for a long time, and we’ve always thought it would be bigger… but this finding is astounding.”

Dr James Farrell, also with the Utah team added:

“We record earthquakes in and around Yellowstone, and we measure the seismic waves as they travel through the ground. The waves travel slower through hot and partially molten material… with this, we can measure what’s beneath.”

“To our…
