Just ran across this resource link, Predicting Volcanic Eruptions . The module is media rich, and flash based.

The intended audence is somewhat younger than the university age students that I teach, but I believe the principles and concepts are good ones – and sometimes, its not a bad idea to have things simply explained.

As described:

This presentation uses data from several eruptive episodes of Mount St. Helens in the 1980’s to show the way in which a series of eruptions were accurately predicted by USGS scientists as far as 3 weeks before eruptive activity occurred. Several modules demonstrate the use of earthquakes and deformation of a volcano for predicting eruptions and allow you to predict an actual eruption of Mount St. Helens using data collected by scientists of the USGS Cascades Volcano Observatory.
