Earthquakes and tsunamis

We provide support to communities to help them develop strategies to avoid and minimize impacts of a catastrophic tsunami event through planning and work to leverage needed resources to take action. However, planning measures must be coordinated with a full range of efforts needed for overall disaster preparedness.

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 in which both 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 our 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.

Earthquake and tsunami hazard information

The Washington State Department of Natural Resources is the lead agency for collecting and disseminating information about earthquakes and tsunami hazards. Visit their website to learn about your risk and programs that work to help Washington prepare for catastrophic hazards.
