State Office of Emergency Services, UC Berkeley to Launches Nation's First Statewide Earthquake Early Warning System

Earthquake early warning alerts will become publicly available throughout California this week, the Governor's Office of Emergency Services said on Wednesday, October 16.

The system's statewide debut of Thursday, October 17 coincides with the 30th anniversary of the Loma Prieta earthquake that ravaged the San Francisco Bay area on Oct. 17, 1989, as well as the annual Great Shakeout safety drill.

The warnings produced by the ShakeAlert system will be pushed through a smartphone app called MyShake and the same wireless notification system that issues Amber Alerts.

The state earthquake app, developed at the University of California, Berkeley, is available for download to IOS users through iTunes and through GooglePlay stores for Android phones.

The system does not predict earthquakes. Rather, it detects the start of an earthquake and calculates location, intensity and sends alerts to areas where shaking is likely to occur from quakes of magnitude 4.5 or greater.

The alerts have been in development for years and last year were made broadly available to businesses, utilities, schools and other entities.

Large-scale public notification has been available for Los Angeles County since the start of the year through an app developed for the city of Los Angeles, but it hasn't been triggered yet.
A 3.4 magnitude after shock took place sometime after 6 am on Wednesday morning, October 16 just outside of Pinnacles National Park and near Tres Pinos. No damages or injuries were reported. This occurred hours after a 4.7 earthquake was felt throughout South Monterey County on Tuesday afternoon, October 15 sometime between 12:30 pm and 1 pm.
