At 10:19 a.m., All AHAB Sirens along the Washington Coast will activate with an actual 90 second siren along with a voice message in both English and Spanish, announcing the test and then again following the siren activation.
Our greatest risk and hazard to any natural disaster is from a Cascadia Earthquake event or from a large inland earthquake. In 2011, during the Tohoku Earthquake and Tsunami in Japan, a tremendous amount of damage occurred prior to the tsunami arriving; especially in Tokyo. To put things in perspective, I’ve included this “you tube” video clip which shows the earthquake as it strikes many areas in Tokyo, Japan in 2011. Tokyo is at 250 miles from the rupture zone of the Tohuku Earthquake. Seattle, WA is about 200 miles from the Cascadia Subduction Zone. Based upon the shorter distance from the Cascadia Fault line to Seattle, damage seen in the video from the 9.0 earthquake could be far more destructive in all areas of Washington from our coast line to Seattle.
