 A new earthquake early warning system is on the way in California. Over the last several years, the earthquake early warning system has really taken several steps forward to become realization. Beta testing is nearly complete. Next stop, San Diego. You know, San Diego is a really beautiful and wonderful place to live, but we do have our faults, as I like to say. There are several faults that run through San Diego County, with the Rose Canyon fault posing the highest threat, and that's the reason for this test of ShakeAlert. Oakland was the site of the first live test of the ShakeAlert system in March. Cal OES and its partners, US Geological Survey and Alameda County, needed to know how long it would take to send a ShakeAlert to cell phones using the Wireless Emergency Alert System, or WIA, which, by the way, is already in use for amber and weather alerts. Everyone has Wireless Emergency Alerts on their phones today, and it's something that we want to use as a pathway. Cal OES earthquake program lead Ryan Arbus says they and the USGS simulated an earthquake in Southern California by triggering the ShakeAlert. WIA grabbed it and sent it to mobile phones in Oakland. That first alert came out four seconds after the test alert was generated, and that's record breaking. A test on a new earthquake warning system is scheduled to take place in Oakland this week. The sample size in Oakland was about 40,000, but the test in San Diego County will target more than 3 million people, and that means more data and a more reliable sample. The more data that we have about how our alert and warning systems function, the better we're able to operate, so we're very excited to partner on this test. San Diego County OES's Holly Porter is leading the way for this test of ShakeAlert through WIA. That's a system that we use for fires. Residents may remember receiving a wireless emergency alert during our LILAC fire in 2017. USGS scientist Bob DeGroote is just as excited about the upcoming test. He says the goal is to continue to do these tests so that we can gain more confidence. So the idea of doing the testing is that we're able to find essentially where the sticking points are, but overall the progress is going very well. He's talking about the sticking points to speed, so on Thursday June 27th at 11 a.m. there will be a scene in San Diego similar to this one. If you receive the alert on your phone, know that it is likely a test. We don't want people to be alarmed. We want to know that people to know that this test is coming. Take June 27th at 11 a.m. as a reminder and an opportunity to take preparedness steps in their own home. For more information about this test, go to readysandiego.org and oesnews.com. I'm Shawn Boyd.
