On January 1st, 2019, The City of Los Angeles, under the oversight of Mayor Eric Garcetti and built on the ShakeAlert system developed by the U.S. Geological Survey released ShakeAlertLA. The project team continues to look for ways to make the app more user-friendly and robust with feedback from the users and partners.
Some of the recent updates are lowering the threshold of the warnings from magnitude 5.0 to 4.5, displaying in Pacific Standard/Daylight Time, adding interruption (do not disturb settings), and links to a demo of what an alert will look and sound like within the app. While there are still many changes that will be made, we aim to provide all users with the best possible app we can make and are constantly trying to find ways to improve it. The app is available for both Apple and Android devices and available in both English and Spanish.
You can also use this app to prepare for an earthquake, get details on recent earthquakes, and find help after an earthquake.

A Collaborative Partnership
The ShakeAlertLA app is brought to you by the Office of Los Angeles Mayor Eric Garcetti, the Information Technology Agency and the Department of Emergency Management. It has been made possible by support from the Annenberg Foundation and the Mayor’s Fund for Los Angeles. This app is an official pilot in partnership with the U.S. Geological Survey.
Please Be Aware, the ShakealertLA Mobile App Was Retired on December 31, 2020
ShakeAlertLA will no longer 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 and on Google Play.
