The worldwide Great Shakeout earthquake and tsunami drill takes place Thursday. Millions around the globe–including an expected 1.5 million Washingtonians–will participate by practicing drop, cover and hold under a desk, table, or other sturdy items in case of an earthquake.
This drill will help practice the action to be taken in case a real earthquake strikes. Those that already have registered include families, businesses, schools, health care facilities, faith-based organizations, neighborhood groups and more.
In recent years, many have had fun at work, school, or elsewhere by taking photos and videos while under a table or desk and posting them on social media.
How the Drill Begins
The drill will kick off when the Emergency Alert System (EAS) is activated at 1015 AM Thursday on the National Weather Service’s NOAA Weather Radio network statewide, and aired by all radio and TV broadcasters and cable systems, including Everett’s KRKO 1380 AM/95.3 FM, and KXA 1520 AM/96.9 FM.
Earthquakes are no-notice events as opposed to significant weather events. They occur at any time of day, whether at home, work, on the road, in school, wherever you and members of your family may be.
For instance, people spend about a third of the lives asleep. If in bed, stay there and cover your head with a pillow until the shaking stops. Have a pair of hard soled shoes under the bed to put on after the quake. Many injuries occur when walking in the dark with bare feet. Also consider a flashlight, gloves, light sticks, and even a hard hat under your bed. Here is a helpful short video on earthquake safety while in bed.
Daily lives also occur at work, school, shopping or while traveling. Schools use this event as their October monthly emergency drill.
It is crucial to consider earthquake safety actions at any location when a quake strikes. Communication with loved ones and work staff is also important. Phone systems will likely be overwhelmed or completely out of service in the wake of a quake.
Having a backup communication plan can be critical. The Great Shakeout drill offers the chance to practice your backup communication plan. Know in advance how and who to reach in case phone and power systems go out of service, which will be quite likely.
In addition and if not already done, download and use the Shakealert app for quakes that are further away. The alert will offer a short time to prepare before the shaking begins.
Washington is Earthquake Country
Recent smaller earthquakes around Vancouver Island and across Western Washington are reminders that Washington is earthquake country, the second most threatened state in the nation behind California. There are many earthquake faults around the region including the Tacoma fault, the Seattle fault, and the South Whidbey Island fault that geologic history has shown all can produce 7.0 magnitude quakes or greater.
And then there is the Cascadia Subduction Zone about 100 miles off the coast that stretches from northern Vancouver Island to northern California. The last time that earthquake zone ‘let go’ was on January 26, 1700, with an estimated 9.0 magnitude tremor. Shaking lasted for up to 5 minutes and generated a Pacific-wide tsunami with tsunami waves inundating coastal regions and into Western Washington interior waters.
Geologists indicate this earthquake source releases pressure about every 300 to 500 years, meaning it could occur at any time now. This subduction zone is similar to others around the Pacific Ocean basin including the one off the coast of Japan that produced a major earthquake and tsunami in March 2011, and recently off eastern Russia and in Panama.
Practice Tsunami Response During the Great Shakeout
When a big earthquake occurs, it is also essential to know if you are in a low-lying coastal tsunami inundation hazard zone, even in the Puget Sound region. Significant ground shaking may be the only warning before a tsunami waves arrive.
Knowing in advance evacuation routes and where to move to higher ground including vertical evacuation in multi-story buildings or towers is imperative. Many outer Washington coastal schools, residents and others plan to also practice walking their tsunami evacuation plans following the earthquake drill.
As part of the Great Shakeout, the outdoor tsunami sirens will be tested with the actual ‘wailing’ sound on Thursday at 1015 AM. Emergency management authorities ask that in response to the tsunami sirens, do not call 911.
Readiness Tips
The annual Great Shakeout is an essential time to learn and practice the drop, cover, and hold response to an earthquake, and fun doing it. In tsunami inundation regions, also exercise the evacuation route by walking to higher ground.

Taking even simple steps to prepare for the next earthquake will help be more prepared for the next major weather event as well.
