Great megathrust earthquakes (∼Mw 8–9) that rupture along the Cascadia Subduction Zone pose significant shaking and tsunami hazards to the U.S. Pacific Northwest. Although these large earthquakes are documented in the geologic record, none have been recorded with modern instrumentation, complicating regional seismic...

In the U.S. Pacific Northwest (PNW), intraslab earthquakes located within the subducting Juan de Fuca slab are responsible for most of the region’s moderate-magnitude seismicity. Historically, these earthquakes have caused significant damage, such as the 2001 M 6.8 Nisqually, 1965 M 6.5 Seattle, and 1949 M 6.8 Olympi...

Studies indicate that the Cascadia Subduction Zone is capable of producing great earthquakes, and, like many other subduction zones, it exhibits along-strike differences in rupture history and plate coupling. Paleoseismic data, locking models, and microseismicity point to a change in seismic behavior around 44.5°N, off...
