Earthquakes and tsunamis

Planning for earthquakes and tsunamis

Coastal Washington is not only vulnerable to chronic hazards such as erosion and flooding but is also subject to potential catastrophic hazards, such as a Cascadia Subduction Zone earthquake and tsunami that will occur in tandem. To be effective, preparing for these disasters requires a full range of efforts and a comprehensive strategy.

Our primary role is helping coastal communities avoid and minimize the impacts of a catastrophic tsunami through planning. There are a number of planning tools that can be used to shape where and how development occurs on the coast. We can help communities navigate options by providing guidance and best practices.

We also work with our state and federal partners to coordinate program improvements and leverage resources to better support community needs. The Washington Coastal Hazards Resilience Network serves as a dedicated mechanism for regional coordination and collaboration. Partnerships among hazard experts and practitioners can enhance the collective capacity for technical assistance and identify opportunities to align community needs with potential funding opportunities.
