Too much B.S.

Bothersome. I didn't sign up for notifications or safety training nags. I was happily using the app to see events in the news and then I start getting notifications about some event they were putting on. When i tried to opt out of notifications, there was a note that i couldn't opt out notifications for that earthquke readiness "event". It says I'd have to opt out of all notifications "close to the date of their event". So I opted out of everything early and they kept notifying me anyway. No respect for my use of my device. Obviously some non profit making money to bother people and not paying taxes. I deleted the damned app. They won't be sending me notifications NOW and they won't get click money.

CHECK your settings

Reading through some of the reviews here I see many users complaining about *things they can easily fix* by spending 5 or 10 minutes understanding the app and its *settings* 🙄

Great concept with serious flaw

Ceases to push alerts if you don’t periodically open the app. Defeats the purpose. This should be a high priority fix. Also would help to see the major faults overlain in CA, OR, and WA. Being a line layer I wouldn’t think it would slow down the app much, if at all. The 3 stars are given as the concept and user experience is great, but the fact that its primary purpose - alerts - glitches out if you don’t open the app for a couple weeks is seriously problematic as the user can be lulled into a false reality.

Helped me

This app works. It warned me multiple times when an earthquake was about to happen in California.

No alerta

Hoy tembló en san Leandro 3.8 y yo tengo configurada el app para alertas desde temblores de 2.5 grados en adelante y la app no emitió ninguna alerta.

FAQ

What does the MyShake app do?

MyShake provides earthquake early warnings for California, Oregon, and Washington using the USGS ShakeAlert system. It also offers earthquake safety tips, a global earthquake map with detailed information, and notifications for earthquakes based on your selected regions and magnitude.

How does the early warning system work?

The app utilizes the USGS ShakeAlert system to deliver alerts for earthquakes of magnitude 4.5 or greater. These alerts are received several seconds before shaking arrives, giving users time to take protective actions.

Is MyShake free to use?

Yes, MyShake is completely free to use with no ads or subscription fees. It is developed by the University of California, Berkeley, Seismology Lab and funded by the California Governor’s Office of Emergency Services.

What kind of information can I find on the earthquake map?

The earthquake map allows you to view and explore earthquakes around the world. You can get detailed information such as the earthquake's magnitude, location, and depth. You can also share your own earthquake experiences and see community reports of shaking and damage.

Can my phone contribute to earthquake detection?

Yes, by participating in the smartphone-based global seismic network, your phone acts as a mini-seismometer. This citizen-science initiative contributes to the detection of earthquakes globally and has the potential to provide early warning alerts even in regions without traditional seismic networks.
