Here's the UWP app in action:
A summary, sorted by time of quake and by distance from my current location. Nothing too close, though didn't Wales have a quake recently? The UI is clean, though bright, and a dive into 'Preferences' (right) doesn't offer a dark theme, which is a shame.
Tapping on an earthquake report gives a map and some basic data, though anything more detailed requires tapping on the Web control and heading to the source on the wider Internet (in Edge).
The app works in landscape, as you'd expect from a good UWP application for Windows 10, but - as often happens - things are optimised more for portrait. Still, you can always plug your phone into a Continuum display, right?
You can grab Earthquake Watch UWP for free in the Store here. It's ad-supported, but you can pay £1.49 (at UK prices) to get rid of these if you like.
