The MyShake app -- developed by the UC Berkeley Seismology Lab, sponsored by the State of California Office of Emergency Services -- is the first app to provide statewide earthquake early warning alerts. The app is one of the delivery modes of the California Earthquake Early Warning System. 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. Get earthquake ready and help your community. Have earthquake information at your fingertips and help create a global earthquake detection system. 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. Stay informed. Get notifications about nearby earthquakes and track earthquakes around the globe. Share your experience. Felt an earthquake? Create and experience report and see reports from fellow users and MyShake scientists. Help improve earthquake early warning. Your device becomes an earthquake sensor and joins a smartphone network collecting valuable data. Learn more at



  • DEAD APP!!!!!!!

    By Dano 33
    DEAD APP! This App is DEAD! USELESS! DELETING NOW! The State of CA & Gov Newsom were pushing Californian’s to get this App because we would get prior alerts, & earthquake notifications! Many Quakes have hit in SoCal & No Warning, not even registered on App. My other Earthquake App is way more reliable and i have had it 3 years! Keeping the other Earthquake App while i Delete this App! I can’t believe UC CAL BERKLEY helped design this App.
  • Feature Request: Ability to subscribe to location

    By iOS6-iPhone_iPad
    I like the idea of this app but I think it can be greatly improved by offering the ability to subscribe to a location for alerts/reports. While it is interesting that there was an earthquake in Indonesia, I don’t want to receive alerts and pop-up’s for it. I mainly care if there is an earthquake happening EAE real-time in San Francisco and would like the feature to only get alerts for this area. It would be great if I can subscribe to alerts by selecting a city or be able to draw the boundary on a map. Thanks again for building this app and sharing the data. Keep up the awesome work!
  • Terrible!

    By ZachStallings
    3 different earthquakes happened in Ventura CA and the app didn’t show them anywhere. The map is also incredibly inaccurate. Useless app.
  • No way to filter notifications by location

    By shidarin
    If you want to be notified of 6.5 mag earthquakes in the middle of the ocean, this app is for you. Unfortunately, the promise of the app is ruined by an inability to add any new notification areas. Your only option is global, which you can set to whatever magnitude you want. You can filter old data by location, but not the earthquake alerts. So every time a larger earthquake happens, you'll be reading the screen trying to determine the location to see if you need to take action. Please let us add a custom notification area so we can turn off global alerts and be given precious extra seconds of warning for LOCAL earthquakes.
  • App has potential

    By ahegevw aga
    Suggestions: Allow users to change warning notification based on shaking intensity expected at their location. Example: User only wants to be notified if there’s moderate shaking expected at their location. Maybe people aren’t ready for this though and perhaps keeping it at MMI III works. Include option for submitting information/reports past 2 weeks, as well as viewing earthquakes/reports over 2 weeks old. I’m not sure why this is the cut off. I wanted to put in information about the shaking I experienced during the Pleasant Hill earthquake, but 2 weeks had already elapsed. Will the phone produce an audible alert if the phone is on silent? Will the phone vibrate if the phone is on vibrate? It’d be nice to hear what the warning sounds like or how your phone will respond when receiving a warning. I think think should be described better within the app and/or there should be an example of what the warning sounds like.
  • So excited to have this and free

    By ToddB8632
    So glad this has been released. This is a big step forward for Earthquake Early Warning.
  • Need regional alert, not global

    As an early warning system, this app is useless. After being inundated with global alerts, likely the regional warning will ignored!

    Major bugs make this app unreliable and unusable. Not well thought out and introduced with fake publicity.
  • Notification center

    By Bisj2929
    When a earthquake it up in Notification Center
  • Need it for the Apple iWatch please?

    By SheilaF
    Got my Test alert today - but I didn’t notice it until a couple of hours later (phone was charging in the bedroom, I was in the yard). An iWatch alert would have notified me right away. Also- I turn the phone’s Do Not Disrurb on during the week at night - concerned I’d miss those too. I really like this alert, I figure a couple of seconds would be a great heads up!
