About this app

MyShake is a comprehensive and free earthquake app offering these features:

Earthquake Early Warning
Receive timely, potentially life-saving early warning alerts in California, Oregon and Washington. MyShake uses the USGS ShakeAlert 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
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 Notification
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).

It would be nice if tbe graph would also show a number maybe at the top in addition to the line? Also wish the recording option could be changed, as one minute is not very long. I appreciate that this app is free. There are apps out there that feel like they are more sensitive (like vibration meter), but those can be expensive so I'll continue to use this one until I find something better.

So, today we had the practice drill. I mostly work at night and sleep in until noon. I noticed that the practice alert was at 10:21am. It's on my phone, but I didn't hear it go off. I keep my phone on silent when I sleep, but my alarm always go off and wakes me up. I thought this app would do the same. It would be awesome, if this app could override the volume settings and just go off with no problems. Just something y'all might want to look into.

Hi, thank you for the feedback. The app will override the volume settings for a real event. We do not use this capability for the test alerts, since those don't require immediate attention.

Update removes functionality! In the previous version, it was easy to see at a glance the size and recency of earthquakes, via size and color of the circles respectively. Now you can only see recency. Also the ability to zoom out has been reduced. Before you could see the whole Pacific at once to see the ring of fire; now you can only see part at a time. Bring back the old UI!

Hi Kristin, we are sorry that the new app still has some design challenges to work through. We did many rounds of user testing for the redesign, but have realized that more users are looking for something a bit different. On a positive note, we have heard your concerns and have noted them down to improve the app and your experience. Thank you!
