Eruption: The Untold Story of Mount St. Helens by Steve Olsen. Join us as we discuss the history and the science behind one of the most massive volcano eruptions in human history. For months in early 1980, scientists, journalists, sightseers, and nearby residents listened anxiously to rumblings in Mount St. Helens. The eruption was one of the largest in human history, deposited ash in eleven U.S. states and five Canadian providences, and caused more than one billion dollars in damage. It killed fifty-seven people, some as far as thirteen miles away from the volcano’s summit. Shedding new light on the cataclysm, author Steve Olson interweaves the history and science behind this event.
