Mount St. Helens' Eruptive Activity
LATE BREAKING SESSION: ABSTRACTS WILL APPEAR IN A LATER SUPPLEMENTAL VOLUME. On 1 October 2004, after a decade hiatus, Mt. St. Helens came back to life with an eruption that produced a column of ash and steam extending some 5 km into the atmosphere. Mt. St. Helens is the most active volcano in the Cascades Range, and provides earth scientists with a natural laboratory to develop and evaluate predictive models for eruptions, and mitigate the associated hazards. The session will focus on the current nature of volcanic activity at Mt. St. Helens, as well as the results of monitoring methods used to forecast eruptions, and their predictive success in this case.
