Earthquake Monitor

Monitor earthquakes globally or at up to four 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 and to populate distances for all earthquakes relative to the custom location.

Tap on an 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 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.

更新履歴
- New server to send earthquake alerts. You must re-register for alerts again by toggling a setting. Only up to four custom locations are allowed now. If you had more than four previously, please delete down to four, or alerts will not come in. If you experience any crashing in an alert screen during the transition process, re-install the app and it will be a clean slate. If you have questions, please email me from the app.
- Periodically check to make sure alerts are coming in as expected by switching to a low global magnitude setting.
- Advertising consent form at startup for European users.
- Updated internal code throughout.
