Mayor Garcetti Calls on Angelenos to Download MyShake

After a two-year pilot phase reached nearly one million users, Mayor Garcetti announces the end of ShakeAlertLA and transition to new platform

The City of Los Angeles will retire the ShakeAlertLA earthquake early warning mobile app on December 31, 2020. The app was a pilot project that laid the foundation for an earthquake early warning alert system in California. Angelenos are now encouraged to download MyShake, a new statewide cell phone app from Earthquake Early Warning California that is powered by ShakeAlert and builds on lessons learned from the City’s two-year ShakeAlert pilot to deliver earthquake early warning alerts to people across L.A. County. 

ShakeAlertLA was the first in the nation public alerting system for delivering earthquake early warning. It sent alerts to users within Los Angeles County that an earthquake of greater than magnitude 4.5 intensity has been detected and that they may soon feel shaking. The app was available for both Apple and Android devices and available in both English and Spanish. You were also able to use this app to prepare for an earthquake, get details on recent earthquakes, and find help after an earthquake. This app was brought to you by Mayor Eric Garcetti and the City of Los Angeles, and built on the ShakeAlert system developed by the U.S. Geological Survey.

Like ShakeAlertLA, the state system uses ground-motion sensors to detect earthquakes that have already started and estimates their size, location, and impact. When it detects a significant magnitude, the system issues a ShakeAlert Message, providing a warning before shaking begins. Earthquake Early Warning California marries the MyShake App and Android Earthquake Alerts with traditional warning delivery methods such as wireless emergency alerts.

ShakeAlertLA will not send earthquake alerts to users after December 31, 2020. Residents who want to receive earthquake early warning notifications should download the MyShake app, which is available on the Apple store or on Google Play.
