QUAKE ALERTS - Get earthquake alerts and tsunami warnings to your iPhone. The system monitors quake activity worldwide and plays a siren sound when you need it.

#1 Earthquake app for iPhone and iPad.
This app is brought to you by SMS Tsunami Warning, the pluri-awarded internet-based quake alert service since 2011.

The app is a quake and tsunami alert system that monitors seismic activity worldwide 24/7 and sends you alerts in the form of push notifications (with a siren sound).

The user interface is simple and easy to use. For a better reading, the map only shows "significant" earthquakes (ie. with magnitude bigger than 4.5 on the richter scale) recorded in the last 24 hours across the globe. In the Settings screen, you can set the parameters for receiving the alerts (ie. your distance from the quake and/or the quake magnitude). After the parameters are set, you can enable (or disable) the alert system in one touch for total peace of mind. The app supports both metric and imperial measurement systems (Kilometers / Miles) to assess distances.

Each quake is represented by a marker on the map. Tap on the marker to open the details panel and dig more into the quake's data (depth, population estimates, etc.). The app is directly connected to our website, where you can learn more about a specific seismic event or, in general, get access to a vast literature concerning earthquakes and tsunamis (how they are generated, features, history, etc.).

The app is a great educational tool and it offers a vital alert service, especially to those living by the coastline or in seismic regions.

The app is free and it contains NO ads. Push alerts are offered as in-app purchase for only $2.99/year (price may slightly vary from country to country).

Intuitive, informative, and easy to use!

This quake alert app is easy to set up and use. For only 2.99 a year, I’ve got access to knowing when and where a quake has stuck. With relatives in areas like japan, it really gives me peace of mind knowing that if something happens, I’ll be able to find out real quick. You’re able to choose between using miles or kilometers in the settings, and the map looks really clean and uncluttered!
