San Diego experiments with mobile earthquake early warning system
San Diego County residents will receive an alert later this month that is part of the California’s testing of an early warning system for earthquakes.
County officials said all wireless phones across San Diego will get an alert at 11 a.m. on June 27 through its Wireless Emergency Alert system. Users will hear a loud tone, followed by a message similar to those sent during AMBER Alert situations or severe weather issues.
Non-county residents’ phones will also receive the test “ShakeAlert” for the California Earthquake Early Warning.
The county’s Officer of Emergency Services is working with the governor’s Office of Emergency Services and the U.S. Geological Survey to conduct the test.
Technology to warn citizens of an earthquake is already available for Los Angeles County residents in the form of the ShakeAlertLA mobile app .
The app, the country’s first publicly available earthquake early warning mobile app, provides alerts for earthquakes in LA County that are magnitude 5.0 or greater.
