Yesterday marked the 25 anniversary of the Mt. St. Helens eruption. NewsDesigner posted a great wrap-up of the front pages of major papers on that very day. Poking around the USGS site, I found a shot of Mt. St. Helens from the day before the blast, and a couple days after. The fallout was extensive and the images unforgettable.

Mount Saint Helens Web Cam provided by the US Forestry Service. Just in case. Also, Valerie Smith's Mount Saint Helens pages, and a comprehensive Mount Saint Helens site from the US geological survey.

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.
