• Tsunami Hazard Maps of the Olympic Peninsula—Model Results from an Extended L1 Mw 9.0 Cascadia Subduction Zone Megathrust Earthquake Scenario

    The Department of Natural Resources recently released new tsunami inundation modeling for the Olympic Peninsula in northwestern Washington to encourage hazard planning and increase community resilience.

    This modeling uses a simulated magnitude 9.0 earthquake along the Cascadia subduction zone, producing a tsunami that is unlikely to be exceeded in the next great earthquake. The simulated earthquake fault geometry assumes a full-length rupture of Cascadia.  Read more here.
