The Coastal Watershed Institute and Peninsula College will mark the 313th anniversary of a Pacific Northwest earthquake and its Pacific Ocean tsunami by sponsoring talks in Port Angeles and Joyce on Friday, Jan. 24, at 2 p.m. in Peninsula College’s Little Theater, 1502 E. Lauridsen Blvd., Port Angeles; or at 7 p.m. at Crescent Grange, 50870 Highway 112, Joyce.

The speaker, Brian Atwater, is a U.S. Geological Survey geologist at the University of Washington.

Atwater will recount detective work, both in North America and in Japan, behind today’s consensus that the Cascadia Subduction Zone produced an earthquake of Magnitude 9, and an associated tsunami, in January 1700.

Both presentations are free and open to the public, and donations to CWI to defray expenses are appreciated.
