Can someone please create a seismic (earthquake) alert or warning system that pulls info from government agencies (i.e.. USGS, etc.), or perhaps also works with a connected cellphone's: internet connection, accelerometer, GPS antennas to both pull information and also crowdsource data using these sensors.
How about you just download some app on your phone that displays seismic warning notifications? In Garmin Connect Mobile you can select what app notifications you want to be relayed to your watch (settings -> smart notifications).
