The Great Washington ShakeOut on Thursday will feature a test using the MyShake Earthquake Early Warning App.
At 10:20 a.m. Thursday, all are invited to drop, cover and hold on wherever you are — whether it’s at work, home or school.
At about the same time, more than 120 Washington tsunami sirens along the inner and outer coast will be tested using the real wailing sound of a tsunami warning, not the Westminster Chimes that are typically used during the monthly tests. NOAA Weather Radios will also sound an alarm.
Those who hear it are asked not to call 9-1-1.
For the first time, a test will go out to those who have downloaded the free MyShake Earthquake Early Warning App on their phones.
The test alert should include test audio telling people that this is a system test and no action is required.
