The ShakeAlertLA app can provide you with critical seconds of warning that an earthquake has begun and shaking is imminent. Alerts are issued when an earthquake of magnitude 5.0 or larger is detected by a regional sensor network and shaking is expected to be felt in the Los Angeles area.
Getting a few seconds heads-up can make a big difference if you need to pull to the side of the road, get out of an elevator, or drop, cover, and hold on. Download the app now!
