Mount St. Helens Rocked our World! What We’ve Learned Since 1980 with Heather Wright, PhD, Volcanologist with the USGS Volcano Disaster Assistance Program

Please note: This event is on Monday, May 18 the 40th Anniversary of the eruption of Mount St. Helens.

Forty years ago, Mount St. Helens experienced a cataclysmic eruption. On May 18, 1980, the northern side of the volcano collapsed, triggering a forceful blast that raced across the landscape, an explosive eruption column that rose vertically in the air, pyroclastic flows that swept down the mountain, and a series of large mudflows that raced down river valleys toward the Columbia River. What did this eruption teach us about volcanic processes and management of volcanic crises? And most importantly, where do we go from here?

As a research geologist, Heather Wright spends a lot of time traversing the flanks of volcanoes around the globe, studying ash and pumice deposits to reconstruct eruptive histories and to provide clues about the inner workings of active volcanoes. Her research focuses on understanding what controls the style of eruption produced during volcanic crises and how to forecast activity prior to an eruption.
