Earthquake Early Warning

Now issuing earthquake early warning alerts in California!
The MyShake app -- developed by the UC Berkeley Seismology Lab, sponsored by the State of California Office of Emergency Services -- is the first app powered by ShakeAlert® to provide statewide earthquake early warning alerts. The app is one of the delivery modes of the California Earthquake Early Warning System. MyShake is available in both English and Spanish.

MyShake is different to all the other earthquake apps. In addition to providing earthquake alerts, maps and safety tips, your phone helps to detect earthquakes.

MyShake provides earthquake early warnings in California for estimated magnitude 4.5 earthquakes and higher to phones in the light shaking (MMI 3), or higher, areas.

Quickly understand the impact of an earthquake. See damage and shaking reports submitted by other community members along with information from the US Geological Survey.

Help improve earthquake early warning. Your device becomes an earthquake sensor and joins a smartphone network collecting valuable data.
