Los Angeles Mayor Eric Garcetti officially launches the nation’s first earthquake early warning mobile application, ShakeAlertLA, designed to detect that a tremor of magnitude 5.0 or greater is striking.
Before the ground shakes beneath their feet, residents in the nation’s second-largest city are now able to brace seconds ahead of time after officials launched the country’s first earthquake early warning app on Thursday.
The ShakeAlertLA app is designed to send a warning to anyone who has downloaded it and is within Los Angeles County when regional sensors placed by the U.S. Geological Survey detect that an earthquake of magnitude 5.0 or greater is striking.
“We often say here in Los Angeles that it’s not a question of if, it’s a question of when the next big one is going to hit,” Los Angeles Mayor Eric Garcetti said at a news conference on Thursday. “We know that we live in earthquake country.”

The app launched on the Apple and Google Play stores on Dec. 31, 2018, after more than a decade of research and development led by the United States Geological Survey.
Screenshots show how alert messages are displayed on the ShakeAlertLA app.
In addition to providing quake alerts, the app also includes tips on preparing for and recovering from a quake.
ShakeAlertLA also includes a listing and map of recent quakes, according to FOX11.

Garcetti’s office said that ShakeAlertLA pilot project was made possible by a $260,000 grant from The Annenberg Foundation in 2017.

While the app is being declared a breakthrough by officials, it does have some limitations.
“A limitation in any early warning system is [the] distance from the epicenter,” the mayor’s office said in a news release. “The further a user is from the epicenter of an earthquake, the greater the warning a ShakeAlert user may receive — inversely, a user who is located closer to the epicenter may receive less warning.”

The L.A.-based pilot has been called a “crucial step” towards the development of an earthquake early warning network across California, and eventually the entire West Coast.
