Steve Olson, writer for Scientific American and author of the new book, "Eruption: The Untold Story of Mount St. Helens," discusses a new project that looks at the plumbing deep beneath the surface of a volcano and how it may be able to more accurately predict future eruptions. The project, "Imaging Magma Under Mount St. Helens" studies how magma moves underground and will be able to assist in the study of volcanoes across the globe and ultimately save lives. Olson discusses how many eruptions still occur without any warning, noting that even though it would be difficult to completely prevent an eruption, some scientists have had success diverting lava flow. We also speak about the fact that over 25,000 people have died as a result of volcanoes since 1980. Olson notes that casualties happen annually and the iMUSH technology hopes to solve that.
