The Oso, Washington landslide – causes, impacts, information learned
Posted August 4, 2014, Length: 32:58
On March 22, 2014, during a month of heavy rains, a significant landslide occurred near the rural town of Oso, WA, about 50 miles north of Seattle, on the steep slope above a river – a slope with a history of landslide occurrences. The slide destroyed about 50 homes and killed 43 people. The event has raised questions about landslide causes and about the feasibility of landslide warning systems. Professor Schofer discusses the Oso landslide, and the topic of landslides in general, with Jeff Keaton, principal geologist for AMEC Americas in Los Angeles. He is a member of the Geotechnical Extreme Events Reconnaissance Association team, also known as GEER, which is supported by the National Science Foundation. GEER teams survey extreme event locations immediately following the occurrences, and did so at Oso.
The Infrastructure Show is sponsored by Northwestern University.
