With its rushing rivers, sprawling canyons and lush forests, Yellowstone National Park is an absolute treasure, but buried deep beneath its picturesque surface lies a hell that's just waiting to be unleashed. Using computer models, researchers have simulated the conditions beneath North America's largest supervolcano - discovering a zone that may control the movement of magma flowing out from the Earth's mantle.
Two years ago, Iceland's Bardarbunga volcano erupted -- and it kept erupting for the next 181 days, forming the largest volcanic depression ever seen. New research reveals the extraordinary processes that transpired beneath the surface, including the formation of a magma-filled canal that measured a whopping 45km long.
