Great Washington ShakeOut: What to know about the earthquake drill happening Thursday

Drop, cover and hold on – the annual Great Washington ShakeOut is happening Thursday, Oct. 19.  

At 10:19 a.m., hundreds of thousands of Washingtonians will join in on earthquake drills at home, schools, businesses, work or outdoor spaces. The annual event happens every third Thursday of October and helps prepare people for what to do when an earthquake or tsunami hits.

The Washington Emergency Management said at about the same time, more than 120 state tsunami sirens along the inner and outer coast will be tested using the real sound of a tsunami warning, and NOAA Weather Radios will also sound an alarm. Officials said the sound will not be the Westminster Chimes that are typically used during monthly tests. 

During the Great Washington ShakeOut, a test will go out to those who downloaded the free MyShake Earthquake Early Warning App on their phones, which is free. The alert system can provide a few seconds of warning before an actual earthquake hits.

More than 1.2 million Washington residents have registered for Thursday's event, as of Oct. 9. 

During the drill, officials are asking people to not call 911. 

FEMA listed the steps to protect yourself during an earthquake: 

  1. Drop (or Lock): Wherever you are, drop down to your hands and knees and hold onto something sturdy. If you’re using a wheelchair or walker with a seat, make sure your wheels are locked and remain seated until the shaking stops.
  2. Cover your head and neck with your arms. If a sturdy table or desk is nearby, crawl underneath it for shelter. If no shelter is nearby, crawl next to an interior wall (away from windows). Crawl only if you can reach better cover without going through an area with more debris. Stay on your knees or bent over to protect vital organs.
  3. Hold on: If you are under a table or desk, hold on with one hand and be ready to move with it if it moves. If seated and unable to drop to the floor, bend forward, cover your head with your arms and hold on to your neck with both hands.
