Now issuing earthquake early warning alerts in California and Oregon!

The MyShake app -- developed by the UC Berkeley Seismology Lab, sponsored by the State of California Office of Emergency Services -- is 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.

As of March 11, 2021, MyShake is also delivering alerts powered by ShakeAlert® in Oregon.

MyShake is available in both English and Spanish.

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 and Oregon for estimated magnitude 4.5 earthquakes and higher to phones in the light shaking (MMI 3) and 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.

Promising but slow/ laggy

Seems like it could be a great app, I personally don’t understand the point of using and or showing the user the x y and z axis change of the phone. But that’s not really the issue here, might just be me but running iPhone X and it seems to freeze for a while whenever I click on a specific earthquake to see more info about it.

Edit: seems to only be freezing on ones that happens around a day or so ago, when I clicked on one that happens 20 mins ago it worked fine but the one that happens in pleasant hill a day or so ago (aswell as others ) it freezes.

Edit 2: the app now shows an earth quake in the pinnacles, CA as 3.5 however yesterday it showed as a 3.6 and when I click on the 3.5 it then shows 3.6 at the bottom.

Hi there, are you speaking about the x, y and z axis on the sensor? If so, that's a tool we have built in the app to show how an earthquake's motion is an all-around impact instead of "up and down" or "side to side." Also, this built-in sensor collects data when in stationary mode and contributes to our global seismic network. As for the frozen screen, we're very sorry for this inconvenience. Currently, we're experiencing a data overload for the recent earthquake which explains why the app is frozen as you try to report it. The Developers are working hard to find a fix, we appreciate your patience at this time. Thanks!

Living in Mexico city we had something like this for a while . But now I live in Los Angeles California and I don't know how people in the US are gonna react when they get the warning a strong earthquake is coming because people In Mexico are already use to getting them alerts that say "Strong earthquake is coming " since they have so many strong earthquakes and an early warning on their phone and they had them for a while . So since this is gonna be new to people in the US who knows how they gonna react ! Also I think we need the Alarm. I know that they have them were they have tornadoes in the US .But in Mexico city when u get the notification on your phone the Air raid siren also goes on really loud all over the city the first time I had no idea what was happening I tought a war was happening when I heard the alarm all over the city till I saw everyone running outside and they were screaming earthquake and sure enough 30 seconds later BAM strong earthquake hit . They should have those in California not only in places were they have tornadoes so people can have time to go hide ! I saw it helps they had about 30 seconds to get outside .

Hi, we're happy that you are thrilled with our app as well. We thank you for your suggestion and happy downloading!

Skippy! ,

Works for me

Everyone in here complaining about little bugs as if they never experienced something like that in another app. This is a free earthquake warning app that could potentially save your life, stop complaining and grow up.

I just downloaded the app and had no issues with using it, but it’s an early warning app not a game, so whatever people are complaining about is pointless because the main function of the app is to send you a push notification.

One thing I did really like is how I can look at the seismograph of past earthquakes to see the pattern of shaking. I was six during the ‘89 quake and still remember how the shaking felt like it was yesterday. Any kind of advance warning will be helpful.

Thank you so much for your kind feedback! We are a small team trying to work as quickly as possible in resolving these issues and we appreciate your patience during this time. We hope you continue enjoying our app as much as we do.
