Quake watch something happened 3 weeks ago and USGS is not working. Therefore I get no info on US.
Speaking from Anchorage Alaska, its wonderful to have such quick access to information when you feel that random bump in the night, or the room starts shaking.
Since most of the buildings are earthquake supported, the floors, especially in the larger buildings can vibrate with the heavy equipment rolling by. This app is especially helpful when we get that 4.0+ quake, and we feel the extra sway of the trusses!
Love this app
