Peering Inside Yellowstone’s Supervolcano

 

 

 

” A giant reservoir of magma and hot rock beneath the Yellowstone supervolcano has been found and imaged. The newly found reservoir lies 12-28 miles below the surface, and is four-and-a-half times larger than the shallower, hot melted rock zone that powers current Yellowstone geysers and caused the caldera’s last eruption some 70,000 years ago.

  The volume of the newly imaged, deeper reservoir is a whopping 11,000 cubic-miles (46,000 cubic kilometers), which is about the volume of Long Island with 9 miles of hot rock piled on it, or 300 Lake Tahoes. The discovery begins to fill in a gray area about how Yellowstone connects to a far deeper plume of heat rising up from the Earth’s mantle.

“ It’s existence has been suspected for a while,” said University of Utah geophysicist Hsin-Hua Huang of the newly imaged hot reservoir. Huang is the lead author of a paper announcing the discovery in the Thursday issue of the journal ScienceExpress.”
