Earthquake Warning California Campaign

Earthquake Warning California is California’s earthquake warning system. This intricate system uses the latest technology, including smartphone applications, operating system features and Wireless Emergency Alerts (WEA), to provide individuals with an earthquake warning as soon as shaking is detected by ground motion monitoring in California.


As part of Earthquake Warning California, the MyShake app is a free earthquake warning tool available in the Apple App store and Google Play to provide individuals precious seconds to take life-saving actions such as to drop, cover, and hold on before shaking is felt. The MyShake App sends a warning to smartphone users in the nearby area that have installed the app as soon as seismic waves are detected and the data is processed.

Last summer, Cal OES announced a partnership with Google that includes Earthquake Warning California technology as a feature included in millions of new Android phones and via software updates in existing Android phones used in California.
