806 NOUS46 KPQR 102142 PNSPQR ...The Great ShakeOut - Thursday October 16... On Thursday, October 16, 2025 at 1016 AM PDT, the National Weather Service Forecast Offices across Oregon and Washington will participate in the Great ShakeOut Earthquake drill. This is part of a global earthquake preparedness effort where millions of people worldwide will practice how to drop, cover, and hold on at 1016 AM PDT on October 16th. You can join by registering for the 2025 Great ShakeOut at www.shakeout.org. 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. The National Weather Service Offices across Oregon and Washington will help kick off the Great ShakeOut drill by disseminating a Required Monthly Test message via the NOAA Weather Radio to activate the Emergency Alert System on October 16th at 10:16 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 sent to cell phones. For the coastal areas of Washington, the Great ShakeOut will include a tsunami drill and a test of the All Hazards Alert Broadcast Tsunami Sirens.The purpose of the test is to get the public familiar with what the sirens will sound like during a tsunami event. All of Washingtons 120+ tsunami sirens along the inner and outer coast will be tested at 10:16 AM AM using the real wailing sound of a tsunami warning, not the Westminster Chimes that are typically used during the monthly tests. Please do not call 911. Preparedness experts encourage you to participate in the Great ShakeOut. You can use the audio recording from https://bit.ly/DRILLRECORDING to make the experience more realistic. $$ www.weather.gov/portland/
