Missing Massive Magma Chamber Found Under Yellowstone

Two huge magma chambers have been spied beneath Yellowstone. This establishes where Yellowstone gets its real source of ash and power. While it's been 640,000 yrs since it erupted, it is slowly ticking off the years to an eventual blast.

Scientists had already known about a plume, which brings molten rock up from deep in the mantle to a region about 60 kilometers below the surface. And they had also imaged a shallow magma chamber about 10 kilometers below the surface, containing about 10,000 cubic kilometers of molten material. But now they have found a deeper one, 4.5 times larger, that sits between 20 and 50 kilometers below the surface. “They found the missing link between the mantle plume and the shallow magma chamber,” says Peter Cervelli, a geophysicist in Anchorage, Alaska, who works at the U.S. Geological Survey’s Yellowstone Volcano Observatory.
