Episode Details

There's always a lot of shaking, rattling, and occasional rolling going on in Yellowstone National Park. Keeping track of it is the Yellowstone Volcano Observatory, one of five such observatories under the purview of the U.S. Geological Survey. It keeps real-time tabs on volcanic, hydrothermal, and earthquake activity in the Yellowstone Plateau volcanic field.

Lynn Riddick speaks with the scientist-in-charge of the observatory, Michael Poland, Ph.D. From his home in Vancouver, Washington, Poland gives us a glimpse into the latest monitoring systems in Yellowstone National Park and the park's recent geologic activity.
