## What is MyShake Earthquake Alerts?

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!

### 5/5 — Helped me

*2026-08-23, version 3.1.36*

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

### 2/5 — No alerta

*2026-08-14, version 3.1.36*

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.

### 2/5 — No Alert: 8/13/2026

*2026-08-13, version 3.1.36*

I was 3 miles from recent earthquake this morning but MyShake never sent an alert.

### 1/5 — Does not alert anymore

*2026-08-12, version 3.1.36*

This all used to be my go to, but now it doesn’t even alert me literally until I open the app. I’m right on a fault line and really rely on something to notify me moments before for the safety of my family. I don’t know what’s changed, but I have an IPhone 16 with the most updated software and I’ve noticed it’s stopped being useful once I upgraded my phone. I’ve had to download other apps in replacement of MyShake.

### 1/5 — No da alertas

*2026-06-27, version 3.1.36*

No aviso   Es más no detecta la actividad ni en la lista.

### 2/5 — Works too well

*2026-06-26, version 3.1.36*

Too many false positives.    Alerts over magnitude 5.5 quakes 100 miles away that I don’t even feel.  Practically gives me a heart attack several times a year over moderate quakes so far away I can’t feel them.   I guess false positives are better than real dangerous quakes that are missed.   That said, I wish they could perfect the model so it only alerts if a quake is actually dangerous in the area my device is at.   I do not need warnings for moderate sized quakes so far away that they are not felt here.

### 4/5 — Spot On

*2026-06-24, version 3.1.36*

I just exp the 2nd time this app notified me about an earthquake. Last time I got a Notification just seconds before the earthquake! This time, I received one about a minute after. I have both MyShake and QuakeFeed. MyShake is dependable, and QuakeFeed is for information. I’m very satisfied with MyShake app!

### 2/5 — Buggy & untrustworthy

*2026-06-24, version 3.1.36*

App frequently crashes at startup. Also disturbingly sends urgent “drop & cover” alerts for events far away, like M6 Mendocino temblor to Santa Clara County residents. Untrustworthy

### 1/5 — DO NOT DOWNLOAD

*2026-06-18, version 3.1.36*

I made the mistake of downloading this app & it got stuck open on my Home Screen forcing me to do a hard shutdown of my phone just so I could delete it. I am now concerned that it will still be active in the background after reading the horror stories in other reviews.

### 1/5 — Stopped working this year

*2026-06-06, version 3.1.36*

Not sure why, for years this app has worked perfectly but since iOS 26 I never get earthquake notifications anymore? I gave it the appropriate permission and nada.
