Deep Magma Chambers Seen Beneath Mount St. Helens

sciencehabit writes with news that scientists have imaged the magma chambers responsible for the 1980 Mount St. Helens eruption. From the Science story: "Geoscientists have for the first time revealed the magma plumbing beneath Mount St. Helens, the most active volcano in the Pacific Northwest. The emerging picture includes a giant magma chamber, between 5 and 12 kilometers below the surface, and a second, even larger one, between 12 and 40 kilometers below the surface. The two chambers appear to be connected in a way that could help explain the sequence of events in the 1980 eruption that blew the lid off Mount St. Helens."
