How bad will the Cascadia earthquake be?

Currently, scientists are predicting that there is about a 37 percent chance that a megathrust earthquake of 7.1+ magnitude in this fault zone will occur in the next 50 years. This event will be felt throughout the Pacific Northwest.

How far will the Cascadia tsunami reach?

80 to 100 feet
The tsunami produced could reach heights of 80 to 100 feet (24 to 30 m). A 2004 study revealed the potential for relative mean sea level rise (caused by subsidence) along the Cascadia subduction zone.

When was the last Cascadia earthquake?

January 26, 1700
Thursday (1/26) marks the anniversary of the great Cascadia Subduction Zone earthquake that shook the Pacific Northwest on January 26, 1700.

How big is an earthquake on the Cascadia fault?

How long will tsunami last after Cascadia earthquake?

Other Earthquake Effects Tsunamis:A M9.0 Cascadia subduction zone earthquake is expected to generate a massive tsunami that will reach the coast of Washington about 20 to 30 minutes after the earthquake; waves may continue to strike the coastline for the next 12 to 24 hours. (Tsunami waves will also travel across the Pacific Ocean.)

Are there any simulations of a 9.0 earthquake?

A University of Washington research project, to be presented Oct. 24 at the Geological Society of America’s annual meeting in Seattle, simulates 50 different ways that a magnitude-9.0 earthquake on the Cascadia subduction zone could unfold.

Where does the M9.0 Cascadia earthquake take place?

The M9.0 Cascadia scenario is based on an approximately 1,000 kilometer (620 mile)-long rupture of the Cascadia subduction zone megathrust fault. The rupture extends from Cape Mendocino, California, to central Vancouver Island, Canada.
