MyShake is an earthquake early warning app developed by the University of California, Berkeley, and the California Governor's Office of Emergency Services (Cal OES). The app uses the sensors in your smartphone to detect the seismic waves from an earthquake and send you an alert before the shaking starts.

How does MyShake work?

MyShake works by detecting the P-waves, which are the first seismic waves that travel from an earthquake. P-waves are typically faster than the more destructive S-waves, which cause the ground to shake. By detecting the P-waves, MyShake can send you an alert before the S-waves arrive, giving you time to take cover.

How accurate is MyShake?

MyShake is still in development, but it has been shown to be very accurate in detecting earthquakes. In a study conducted by the University of California, Berkeley, MyShake was able to detect 95% of earthquakes with a magnitude of 5.0 or greater within a 10-mile radius.

How do I get MyShake?

MyShake is available for free from the App Store and Google Play.

What should I do if I receive a MyShake alert?

If you receive a MyShake alert, drop down to the ground, cover your head and neck, and hold on to something sturdy. Stay indoors until the shaking stops. If you are in a car, pull over and stay inside until the shaking stops.

MyShake is an important tool that can help you stay safe during an earthquake. By downloading the app and following the instructions, you can give yourself time to take cover and protect yourself.
