Early Morning Earthquakes in Los Angeles Rattle Residents; the State Urges Angelenos to Be Prepared for Future Seismic Events


Download the No Cost, MyShake App to alert you about a future earthquake

SACRAMENTO – At 4:44 a.m. this morning, a swarm of earthquakes struck Los Angeles, rattling early risers and awakening residents. While the quakes did not cause any damage, these latest tremblers offer a reminder to Los Angeles residents, and others in high earthquake risk areas, the importance of preparedness for future earthquakes.

The California Governor’s Office of Emergency Services (Cal OES) urges Angelenos to learn more about the Earthquake Warning California Campaign and download the statewide earthquake early warning app, MyShake. California is the first state in the nation to offer a statewide earthquake early warning system.

Earthquake Warning California Campaign

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

My Shake

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 a few 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.

The MyShake App has been downloaded more than one million times since it was publicly launched in 2019. Last summer, Cal OES also 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.


To learn more about Earthquake Warning California, including industry-specific informational toolkits, background about earthquake warning technology in California, and links to resources that can help Californians employ the latest technology ahead of the next earthquake, visit earthquake.ca.gov.

In December 2020, Los Angeles Mayor Eric Garcetti announced that the city of Los Angeles would begin encouraging Los Angeles residents to download the MyShake App.
