Los Angeles has become the first city in the U.S. to deploy an earthquake early warning app for the public. The app, called ShakeAlertLA, uses a network of seismic sensors distributed throughout the region to detect earthquakes and dispatch a warning to smartphones when shaking is expected in Los Angeles County.
It was developed by Mayor Eric Garcetti’s office in partnership with the U.S. Geological Survey, AT&T, and the Annenberg Foundation. “Angelenos should have every chance to protect themselves and their families when there’s a major earthquake,” said Garcetti in a statement.
“We created the ShakeAlertLA app because 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.”
