The MyShake app -- developed by the UC Berkeley Seismology Lab, sponsored by the California Governor’s Office of Emergency Services -- was the first app powered by ShakeAlert® to provide statewide earthquake early warning alerts in California. The app is one of the delivery modes of the California Earthquake Early Warning System.

MyShake provides earthquake early warnings in California, Oregon, and Washington for estimated magnitude 4.5 earthquakes and higher to phones in the light- heavy shaking areas. Alerts will not go out for all felt events, just damaging ones.

I'm deleting this app for two reasons. First, it constantly runs & appears in the foreground even when the app is closed. As a result, I keep getting warnings about excessive battery usage. Second, when we went to test the alarm, nothing happened. That's because the alarm is a media recording that requires the media volume to be turned up. Both my wife and I keep our media volume turned off so we don't get stupid beeps, bobs and jingles. The alarm should be a ringtone or system sound.

We are sorry you are having a bad experience. The foreground process is part of the citizen science project. You can disable that in settings -> battery saving mode. The test alarm is a media recording to make it small and useable in the app. The real alert is louder and will push through silent or vibration settings.

It keeps notifying me about earthquakes all over even though I set a specific home base. By now I got used to just ignoring the frequent notifications and therefore the app. Al's like others mentioned, the audible alert so a media playback, not a high priority ring/notification tone which would still play even if volume is off. Simply not reliable.

Global notifications are enabled by default. If you would like to turn those off, please go to Settings -> Recent Earthquake Information. Early Warning alerts associated with HomeBase will only sound if you are in the area of impact for a M4.5 or greater event. It will be an audible tone followed by verbal instructions.

The app's pretty hit & miss. It crashes regularly on android and I need to start it back up all the time. I've had recent 3.5+ quakes nearby that don't show up on the map. I would think the map would update with all recent quakes over 3.0 as it will display them in the list, sometimes they don't even show up on the list. And the 4.5m thresh hold is kind of silly. It should be 3.0+ nearby 4.5+ further away, based on geographical location. I've had recent 4.0+ quakes nearby with no warning. I assume the logic is, if I didn't get an alert it's unlikely it's over 4.5 and no cause for alarm. But people want to know what it is and have a reliable warning for all quakes. Similar to how EEW works.

We are restricted by our license to only alert above M4.5. Legally we have to abide by that threshold. The map shows M3.5 or higher quakes, we understand that is annoying, so we are working on a fix. We also experience a heavy load right after an event and the map lags on refresh with so many users on at once, we are looking into a fix for this.
