MyShake Earthquake Alerts

About this app

MyShake is a comprehensive and free earthquake app offering these features: Earthquake Early Warnings Receive timely, potentially life-saving early warning alerts in California, Oregon and Washington. MyShake uses the USGS ShakeAlertTM system to deliver alerts for earthquakes of magnitude 4.5 (or greater) several seconds before shaking arrives. Earthquake Safety View safety tips for earthquake preparedness such as securing hazardous or moveable items and creating a disaster plan. Know what to do during an earthquake and learn more about Drop, Cover and Hold On! Earthquake Map and Details View and explore a map of earthquakes around the world and get detailed information such as earthquake magnitude, location and depth. Share your own experience of an earthquake and see community reports of shaking and damage. Earthquake Notifications Stay informed of earthquakes as they occur by receiving notifications on your phone. Select your regions of interest and the earthquake magnitude. You’ll never miss out on any earthquake greater than magnitude 3.5! Smartphone-Based Global Seismic Network Participate in a smartphone-based global seismic network. In this research project, your phone becomes a mini-seismometer and contributes to the detection of earthquakes wherever you are. This global citizen-science based seismic network has the potential to provide early warning earthquake alerts in every region of the world, even in the absence of traditional seismic networks! About Us MyShake is developed by the University of California, Berkeley, Seismology Lab and funded by the California Governor’s Office of Emergency Services. The Berkeley Seismology Lab conducts essential research on earthquakes and solid earth processes while collecting and delivering high quality geophysical data.
