Phase 2: A Stochastic Model for Potential Tsunamis in the Pacific Northwest - Effect on local tsunamis from spatial variations of slip during rupture. Message from FEMA RIX Regional Administrator and the Governor’s Office of Emergency Services Director . Test will simulate a 9.0 magnitude quake along the Cascadia Subduction Zone, followed by a tsunami. This subduction zone can produce earthquakes as large as magnitude 9 and corresponding tsunamis.

The Cascadia Subduction Zone off the coast of North America spans from northern California to southern British Columbia. The Cascadia Subduction Zone (CSZ) "megathrust" fault is a 1,000 km long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino California. A series of 8 earthquakes hit the Cascadia Subduction Zone and the Mendocino Fracture zone on March 8, 2020 The biggest quake of the swarm was a M5.8 followed by a M4.9 three hours later. The second largest tremor, a M4.9 quake hit around 3 … Its tsunami would cross the Pacific Ocean and reach Japan in about 9 hours, so the earthquake must have occurred around 9:00 at night in Cascadia on January 26, 1700 (05:00 January 27 UTC).

A., 2000, Tsunami hazard map of the southern Washington coast—Modeled tsunami inundation from a Cascadia subduction zone earthquake: Washington Division of Geology and Earth Resources Geologic Map GM-49, 1 sheet, scale 1:100,000, with 12 …
A high-resolution numerical model was used to estimate tsunami propagation and inundation along the outer coast of southwest Washington. The NOAA Center for Tsunami Research modeled tsunami inundation from a great Cascadia Subduction Zone earthquake for the coastal communities of Long Beach and Ocean Shores, Washington. A series of 8 earthquakes hit the Cascadia Subduction Zone and the Mendocino Fracture zone on March 8, 2020 The biggest quake of the swarm was a M5.8 followed by a M4.9 three hours later.
