Mount St. Helens Volcano

(Cascade Mountains, WA)

A one-day field trip to Mount St. Helens is planned during the IODP Workshop Addressing Geologic Hazards Through Ocean Drilling Workshop, to examine the details of debris avalanche deposits and damage resulting from volcano collapse that accompanied the May 18, 1980 eruption [Read more]. After ~20 years of quiescence, Mount St. Helens reawakened in September 2004, producing intermittent steam and ash explosions [Read more]. Activity at the volcano has continued since 2004, slowly but steadily building a new lava dome inside the volcano's crater. Further information about past and present events at Mount St. Helens can be found at the USGS/CVO website.

More details will be provided here about field trip plans as they become available.
