Magma Chamber Beneath Yellowstone National Park Likely to be Bigger than Thought

By Dragos Mitrica, ZMEScience – Beneath one of the most famous touristic attractions in the world, the Yellowstone National Park, there lies one of the largest and most complex volcanic systems in the world. Yellowstone is a supervolcano of perplexing size, but as Utah seismologists found… it may actually be even bigger than previously thought. “For the first time, we have imaged the continuous volcanic plumbing system under Yellowstone,” said co-author Hsin-Hua Huang, a post-doctoral researcher in geology and geophysics at the University of Utah. “That includes the upper crustal magma chamber we have seen previously plus a lower crustal magma reservoir that has never been imaged before and that connects the upper chamber to the Yellowstone hotspot plume below.” A supervolcano is technically defined as any volcano capable of producing a volcanic eruption with an ejecta volume greater than 1,000 km3 (240 cubic miles). Just so you can get an...
