My Shake is a free smartphone app that gives you audio and visual warnings about shaking. It will warn you when shaking is at a magnitude 4.5 or higher.

The My Shake App sends a warning to mobile phone users that shaking is about to happen. The system uses ground-motion sensors to detect earthquakes that have already started. It estimates their size, location, and impact.

When it detects a significant magnitude shake, the system issues a ShakeAlert® Message. This gives you a warning before the shaking starts. The app is also available in Spanish.

Download the free app from the Apple App Store or Google Play.
