Plate Tectonics & Cascadia Earthquakes

The Wenatchee Valley Erratics, Ice Age Floods Institute’s next Zoom program, “Plate Tectonics and Cascadia Earthquakes,” will be on Tuesday June 8 at 7:00 PM with Kelsay Stanton, Erratics past vice-president and current UW PhD candidate.

California is known for its earthquakes, but what about the rest of the west coast? What are our seismic hazards? Why don’t we have as many earthquakes as our more southerly neighbor? This talk examines the tectonic setting for the Pacific Northwest and its many seismic sources, such as:

• – “The Big Ones,” megathrust earthquakes caused by the Juan de Fuca plate subducting under North America;
• – Slow slip earthquakes and episodic tremor and slip;
• – Deep crustal earthquakes, such as the 2000 Nisqually event;
• – And shallow crustal earthquakes, such as the 900 Seattle fault earthquake, and the 1872 Central Washington earthquake from the fault near Entiat.

Kelsay will show how these fit into the tectonic picture, and what it means for shaking in Central Washington and beyond.
