California launching statewide early earthquake warning app

On Thursday, California will make MyShake, a smartphone app that sends out early earthquake warning alerts, available to all residents.

This app is the first of its kind, the Los Angeles Times reports, and is being released on the 30th anniversary of the deadly Loma Prieta earthquake that hit San Francisco. The state will also begin issuing early warnings through the Wireless Emergency Alert system, sending text messages to people, whether or not they have the app.

Funded by the California Office of Emergency Services and developed at the University of California, Berkeley, MyShake uses sensors throughout the state to detect when an earthquake is beginning, then calculates the intensity and location. Alerts are then pushed out if the earthquake is expected to have a magnitude of 4.5 or greater.
