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.

MyShake is available in English, Spanish (Español), Chinese Traditional (繁體中文), Filipino, Korean (한국인), and Vietnamese (Tiếng Việt).

MyShake is available to everyone for free with no ads and no subscription!

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 .

Switched to this app = better!

Switched to this app from another earthquake app and this is better since it allows a home base to be set. Yes there is a sw bug that the app doesn’t seem to do anything after setting the home base, but if you go back through the settings the home base has indeed been set. Home base is essential to me since I run with location tracking off to save battery capacity. I run with a VPN so we’ll see if the app works with that. It would be great if there was a test mode that would allow a user to verify notification and trigger off any earthquake of any magnitude 3.5 or greater in California, Oregon or Washington.

I would also like a notification of ANY deep earthquake on the Cascadia subduction zone in case there are any precursor earthquakes providing early warning.
