Magnitude 9 Earthquake Scenarios

Magnitude 9 Earthquake Scenarios – Probabilistic Modeling, Warnings, Response and Resilience in the Pacific Northwest (“M9”)

The M9 Project is a team of experts whose goal is to reduce catastrophic potential effects of a Cascadia megathrust earthquake on social, built, and natural environments through the advancement of methodologies, early warnings, and community planning.

A magnitude nine (M9) earthquake along the Cascadia fault would cause immense shaking, liquefaction, and trigger landslides and tsunamis from British Columbia to northern California. The resulting losses would cost tens of billions of dollars and thousands of human lives. The University of Washington’s M9 Project is working to address the scientific and engineering challenges in reducing this risk.
