ShakeAlertLA is designed to work with the U.S. Geological Survey’s earthquake early warning system and was an created under the oversight of Mayor Eric Garcetti.
It has been under development for years. It’s designed to give users seconds, and perhaps even tens of seconds, before shaking from a distant earthquake arrives at a user’s location.
The app will send you information when a 5.0 or greater earthquake happens in Los Angeles County, often before you feel shaking.
“By advancing earthquake early warning technology, we are making Los Angeles stronger, making Angelenos safer,” Mayor Eric Garcetti told reporters in October. “And it’ll help save lives, most important, by giving people those precious seconds to stop elevators, to pull to the side of the road, to drop, cover and hold on."
ShakeAlertLA is now available for download on Android and Apple smartphones.
