PORT ANGELES — One January night in 1700, tectonic plates shifted abruptly beneath the ocean floor off the Olympic Peninsula in a magnitude-9 earthquake, setting off the Cascadia Subduction Zone tsunami.
Its impact was felt as far away as Japan, but it was several centuries before researchers began to recognize the connections between earthquakes and tsunamis in the Pacific Northwest.
These connections are the topic of a presentation by Dr. Brian Atwater, a geologist with the University of Washington and the U.S. Geological Survey, who will talk about the detective work behind current tectonic connections at two gatherings, both free and open to the public, today.
Atwater will speak at 2 p.m. in the Little Theater at Peninsula College, 1502 E. Lauridsen Blvd.
He will also give a presentation at 7 p.m. at the Crescent Grange at 50870 state Highway 112 in Joyce.
Cascadia Subduction Zone
With the presentations of “The Orphan Tsunami of 1700,” the Coastal Watershed Institute and Peninsula College mark the 314th anniversary of the Cascadia Subduction Zone tsunami.
Atwater has been a USGS scientist since the mid-1970s and is a member of the National Academy of Sciences, a fellow of the American Geophysical Union and an affiliate professor at the University of Washington.
The Coastal Watershed Institute is a 501(c)(3) based in Port Angeles that is dedicated to promoting “understanding, protection and wise management of watershed resources.”
