A smartphone application that is able to send alerts seconds before an earthquake hits Southern California is now available for the public, Los Angeles Mayor Eric Garcetti announced on Jan. 3.
ShakeAlertLA, the first of its kind in the United States, is a free app that allows users to receive warnings when an earthquake of magnitude 5.0 or larger is detected across Los Angeles County. The earthquake early warning app was developed through a collaborative effort from the United States Geological Survey (USGS), AT&T, Garcetti’s office, and the Annenberg Foundation.
Although the official announcement was made on Jan. 3, the application was launched in the Apple and Android app stores on Dec. 31, 2018, fulfilling a promise that Garcetti made in 2017.
According to the statement from Garcetti’s office, ShakeAlertLA is only a pilot project and aims to provide the entire West Coast with an early-warning service. Data used in the app is collected and shared by the ShakeAlert System, which has been developed and tested by the USGS for more than a decade.
“The City of LA is an important ShakeAlert partner, undertaking the nation’s first test of delivering USGS-generated ShakeAlerts to a large population using a city-developed cell phone app,” USGS Director James Reilly said. “What we learn from this expanded pilot in LA will be applied to benefit the entire current and future ShakeAlert system.”
However, the warning’s effectiveness depends on the distance from the quake epicenter.
“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,” Garcetti’s office stated.
