Volcanoes! Whether we're talking about Pompeii, why some volcanoes in Indonesia are erupting with blue lava, or the mechanics of supervolcanoes, they're totally fascinating. Today, we have a volcanologist in to answer your questions about volcanoes, eruptions, and their aftereffects.
Charlie Mandeville is a volcanologist at USGS. His research has ranged from looking at the mechanics of volcanic eruptions, the geochemistry of volcanic rocks, and the inner workings of magma. He's the Program Coordinator of the USGS's Volcano Hazards Program (which covers volcano observatories in Hawaii, Alaska, Cascadia, California, and Yellowstone) and of the Volcano Disaster Assistance Program. Before he was at the USGS, he was a Senior Research Scientist at the American Museum of Natural History and his Ph.D. research at the University of Rhode Island Graduate School of Oceanography focused on the infamous 1883 eruption of Krakatau in Indonesia.
He'll be joining us from 10:30-11:30 A.M. (Pacific time), so start asking him your questions now about volcanoes, how they erupt, and just what kind of aftermath they can leave.
