02.27.2019 7:00 pm - 8:00 pm


Brian Atwater, a U.S. Geological Survey scientist based at the University of Washington, will speak in Longview on Wednesday evening, February 27, on "Clues to the giant Cascadia earthquake of January 1700." The talk will take place from 7 to 8 p.m. in the science auditorium, HSB 101, at Lower Columbia College.

Dr. Atwater’s discoveries contributed to scientific consensus that the Pacific Northwest has a geological history of earthquakes as large as magnitude 9. His presentation will focus on the most recent of these. He will also present evidence that at our latitude, the earthquakes have occurred at intervals ranging from a few centuries to a millennium, with an average of about 500 years.

This is a free public program sponsored by the Willapa Hills Audubon Society, the volunteer conservation group serving Cowlitz, Wahkiakum and Pacific counties in southwest Washington and Columbia County in Oregon. For more information call Darrel Whipple at 503-556-9838.
