Can we predict volcanic eruptions? PBS aired a NOVA program called "Deadly Shadow of Vesuvius" in 1998 which suggests that we can by monitoring small scale earthquakes which "swarm" as an eruption approaches. Why is this important now? Look at this map, which indicates the occurence of over 40 earthquakes under Mount St. Helens just today, with 10 being over 3.0 on the Richter scale. The Pacific Northwest Seismograph Network has issued a series of alerts with more detail. National Geographic is reporting that an eruption is imminent.
