Monitor earthquakes globally or at up to 10 custom locations.

For each location you choose to monitor, you set the cutoff magnitude and radius.

Browse earthquakes in the past 24 hours or past 30 days in map mode or feed mode.

Use the slider to quickly filter earthquakes by magnitude.

Set a custom location in feed mode to find the closest recent earthquakes to that location.

Tap on a earthquake to show more details including depth and felt-by numbers.

Drilling into a specific earthquake also reveals options to jump to the USGS event webpage with a separate option to plot cities near the epicenter with their populations.

Also included:
- A Today View Widget for quick access to earthquakes in the past hour. Tap an earthquake from this table to jump to its specific page in the app.
- Detailed earthquake notifications with a built-in epicenter map on iOS and watchOS.
- A watchOS app for access to the past hour of earthquakes, including zoomable maps, felt by numbers, and depths.
- 3D touch the app icon to bypass the main app menu in convenient ways.

Please read the App Help File and FAQ for more specific usage information.

All data is from the USGS (United States Geological Survey).

There is a fixed banner ad from Google on the bottom of most of the screens.

What's New

Version 2.2.1

- Fix for crash when adding anew local notification recipe.
- Today View extension now shows the most recent mag 3+ earthquakes only. The last one or four will be visible, depending on whether you have it configured to "Show Less" or "Show More". Before, it would shower lesser quakes.
- The 3D touch from the app icon earthquake hinter now shows the most recent mag 3+ earthquake.
- Fixed a bug where sliding the magnitude slider while the earthquake data was loading would result in a crash. Now, it is handled correctly.
- Fixed UI inconsistencies when notification settings for Earthquake have been denied manually from the iOS Settings app.
- Added USGS Big Quakes (@USGSBigQuakes) to the Twitter section. Also, removed a defunct Twitter source.
- Added a 20px white spacer above all ads throughout the app.
- Updated FAQ text.
- Small bug fixes and improvements

Very nice free earthquake app

With the Earthquake Monitor app I can set it to notify me if an earthquake occurred within a selectable distance around me as well as being able to set the magnitude level of the earthquake. Initially I set it to all earthquakes of magnitude 1 or greater to verify that the notifications were working. I got a notification in less than 30 minutes. The notification came with a distinctive audio alert so as to easily discern that it was an earthquake notification. Also there is a tsunami alert capability such that if an earthquake is judged to be capable of creating a tsunami then I would get notified of those regardless of the range or magnitude setting.

The app also has a list capability showing all earthquakes occurrences in the last 24 hours. There is a unique slider at the top of the list such that I can quickly filter the list to earthquakes of a certain magnitude or greater. This is the only app I have seen that lets me quickly filter the earthquake list to precise magnitude level. Other apps I've seen are more general, e.g. any quake greater than magnitude 5.
Earthquake time listings are automatically adjusted for my local time zone. Most apps I've seen display the earthquake occurence in GMT time.

Also, earthquakes can be displayed as distance and bearing from my location. So I can easily sort the list by distance so that I can see earthquakes that are close to me.

In summary Earthquake Monitor is a very nice and free earthquake app.


Great start

I have been using this app, along with two others, for six days. Of these, this app seems to have the most reasonable default notification settings - moderate quakes near me, and major quakes worldwide. Other apps alert me to minor quakes worldwide (alert overload) and imperceptible quakes near me, and want me to make in-app-purchases (IAP) to change the settings.

Unfortunately, many quakes have the Possible Tsunami tag line added, unnecessary. I'm pretty sure a 4.1 quake is hardly likely of triggering even the most localized of tsunamis…


Works Great very basic and easy to use...

App was hard to find at first (keyword earth quake wasn't showing it but USGS did) App functions great and is customizable on distance and magnitude alerts. On the Santas list the ability to change the sound to something more alert (louder) if needed. Easy to use!
