Preparing for the ‘Big One’—Understanding Cascadia’s next Great Earthquake
June 11, 2019 @ 7:00 pm - 8:30 pm
Wenatchee Valley Erratics Chapter of the Ice Age Floods Institute will meet at 7:00 P.M., Tuesday, June 11 at the Wenatchee Valley Museum, 127 South Mission, Wenatchee.
The last great Cascadia earthquake occurred in January 1700, before seismic instruments were around to record the temblor. Therefore, little is known about the ground-shaking and damage that occurred. Dr. Erin Wirth, Research Geophysicist, will discuss results of computer simulations at the U.S. Geological Survey and University of Washington, that demonstrate 50 different ways a magnitude 9 earthquake could unfold. Researchers are using these findings to evaluate the effects on buildings, the potential for soil liquefaction and landslides, and to understand how the Pacific Northwest should prepare for such an event.
The program is free & open to the public.
