image: The gorgeous colors of Yellowstone National Park's Grand Prismatic hot spring are among the park's myriad hydrothermal features created by the fact that Yellowstone is a supervolcano -- the largest type of volcano on Earth. A new University of Utah study reports discovery of a huge magma reservoir beneath Yellowstone's previously known magma chamber. That doesn't increase the risk of an eruption, but means scientists are getting a better view of Yellowstone's volcanic plumbing system. This material relates to a paper that appeared in the April 24, 2015, issue of Science, published by AAAS. The paper, by Hsin-Hua Huang at the University of Utah in Salt Lake City, Utah, and colleagues was titled, "The Yellowstone magmatic system from the mantle plume to the upper crust." view more
