Are you prepared for tsunami hazards in Washington?

Read our new tsunami brochure to find out…

Just over 56 years ago in March 1964, the Great Alaskan magnitude 9.2 earthquake created a tsunami that spread across the Pacific Ocean. This tsunami reached Washington’s shores within 5 hours, and is an example of a distant tsunami event. The largest wave heights in Washington of almost 15 feet were recorded within Wreck Creek near Point Grenville. Wave heights of about 10–12 feet were recorded at Ocean Shores and Seaview, both located on Washington’s southwestern tip.

The anniversary of the Alaska event is a good reminder to ask yourself if you are prepared for tsunami hazards. Do you know routes to high ground? Are areas you frequent, such as your home, workplace, or school located within a tsunami hazard area?


We have created a tsunami brochure to help you understand tsunami warning signs and prepare for tsunami hazards in Washington. We hope you and your family will be able to use this to make an emergency plan and emergency kits that will assist in the event of a tsunami. Click on the picture above to download the brochure and check out our tsunami page for more information.
