Earthquake Warning California is managed by the California Governor’s Office of Emergency Services (Cal OES) and is the country’s first publicly available, statewide warning system. The warning system is designed to give California residents a few moments warning to take cover before shaking occurs. 

To receive earthquake warnings, Californians can download the free MyShake App, which is available in the Apple App Store and Google Play store.
