Is Seattle overdue for an earthquake?
According to recent studies, Washington State is 200 years overdue for a 9.7 magnitude earthquake. Experts suggest that this earthquake will occur at the Cascadia subduction zone at some point within the next 50 years.
Is Seattle on a subduction zone?
The Cascadia Subduction Zone is close enough to Seattle to cause serious damage to the city. A Cascadia Subduction Zone earthquake could be as severe as a 9.0 magnitude, resulting in shaking so strong that one would barely be able to stand during the earthquake.

Will the San Andreas fault affect Seattle?

How would the Big One affect Seattle?
The simulator shows what would happen if a 9.0 earthquake hit the Cascadia subduction zone – also known as “the big one.” The study estimates that the earthquake would generate a tsunami capable of submerging coastal areas as well as most of the shoreline in Puget Sound with several feet of seawater.
What cities will be affected by the Cascadia earthquake?
Coastal Pacific Northwest
Called the Cascadia subduction zone, a big quake along this fault could affect the cities of Seattle, Tacoma, Portland, Eugene, Salem, and Olympia.
How far inland will the Cascadia earthquake reach?
The shaking will be felt for hundreds of miles – from the coast all the way inland to Boise, Idaho, even to the southeast toward Sacramento in California. As one section of the sea floor drops, so will the ocean water above it creating a massive tsunami that will inundate low-lying coastal communities.
What tectonic plate is Seattle on?
Seattle lies near to the boundary between the North American tectonic plate and Juan de Fuca, a large oceanic plate. The 700-mile plate boundary, known as the Cascadia Subduction zone, runs from northern California to Canada, and all along it, the Juan de Fuca plate is trying to force its way under North America.
How deep is the Seattle Fault?
Based on microseismicity, Brocher and others (2001 #4718) favor a model in which the Seattle fault zone dips steeply from the surface to a depth of about 25 km.
