In a re-broadcast from Nov. 28, 2010, Keith and guest co-host Tom Gill of the UTEP Geological Sciences Department talk with Tom Casadevall, Scientist Emeritus with the US Geological Survey. Casadevall tells us about his early fascination with volcanoes, and what led him to become a vulcanologist. He also reflects on the 2010 volcanic eruption in Iceland that disrupted air traffic across Europe. And Casadevall explains why the 1980 Mount St. Helens eruption was a career-defining event for him.
