On Thursday, October 16, 2025 at 1016 AM PDT, the National Weather Service Forecast Offices in Seattle, Portland, Spokane, and Pendleton will participate in the Great Washington ShakeOut Earthquake and tsunami drill with state and local emergency management officials. This is part of a global earthquake preparedness effort.  

Millions of people worldwide will practice how to drop, cover and hold on at 1016 AM PDT on October 16th during the Great ShakeOut. Washingtonians can join them by registering for the 2025 Great Washington ShakeOut. Participation is a great way for your family or organization to be better prepared to survive and recover quickly from big earthquakes and their impacts. Over one million people in Washington are expected to participate. Register for free today at www.shakeout.org/washington

National Weather Service Offices across Washington will disseminate a Required Monthly Test (RMT) message via the 21 NOAA Weather Radio stations that serve the state to activate the Emergency Alert System (EAS) to help kickoff the Great ShakeOut drill on October 16th at 1016 AM PDT. Broadcasters will carry the EAS message on television and radio to help reach more of the state's residents, along with those who have all-hazard weather radio receivers. This will not be a test of the Wireless Emergency Alerts (WEA) sent to cell phones. 

Preparedness experts encourage you to participate in the Great ShakeOut. This is an audio recording you can use to make the experience more realistic:
