Science Odyssey: Hell Hath No Fury Like an Angry Volcano

After Iceland's Eyjafjallajokull volcano blew its top, European air traffic was paralyzed and thousands of travelers on both sides of the Atlantic were stranded. In this week's episode, we talk with the Smithsonian Institute's Ed Venzke about the Icelandic volcano and why its ash is so dangerous to aircraft. Then we speak with volcanolgist Tobias Fischer (at left) about why some volcanoes are pussycats and others are tigers. Finally, we hear from geologist David Loope about the supervolcano building up pressure under Yellowstone National Park.
