In this episode of the series “Enviro-Tacklebox” from September 18, 2002, host Greg Grandy and the student reporters explore the changes to the Earth’s surface caused by volcanic eruptions, earthquakes, and sinkholes. Grandy first visits the Mount St. Helens National Volcanic Monument in Washington. He interviews Ed Klimasauskas, a USGS geologist, and Peter Frenzen, a scientist at Mount St. Helens, who discuss volcanoes and the eruption of Mount St. Helens on May 18, 1980. Next, he visits the San Francisco Bay Area in California to learn more about earthquakes. He interviews: Mike Blanpied, USGS geophysicist; Douglas Dreger, a seismologist at the University of California-Berkeley; Matthew D’Alessio, a geologist at UC-Berkeley; Timothy Dawson, USGS geologist; and Lind Gee, a seismologist at UC-Berkeley. Then, Grandy visits the Earthquake Engineering Lab at Stanford University in Palo Alto, California. He interviews Greg Deierlein, a structural engineer, who discusses the research done at the lab. Lastly, he visits Tampa Bay, Florida, and interviews geologist Bill Wilson, who discusses Florida’s sinkhole problem.
