Quakescan shows you recent earthquakes near your location, pulling live data directly from the USGS Earthquake Hazards Program — the same source used by seismologists worldwide.

Tap any earthquake to see it on a map with full USGS details and a direct link to the source data. Filter by radius (50 to 500 km), time window (1, 7, or 30 days), and minimum magnitude. Results are cached locally so the app stays useful with a spotty connection. Pull to refresh for the latest data.
