About Quakescan
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. No account, no ads, no tracking. Open the app and see a clean list of nearby quakes: each one shows its magnitude, distance from you, time since the event, and depth. 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. Features: • Nearest-first earthquake list with magnitude color coding • Tap-to-detail: map, depth, felt reports, alert level, USGS link • Adjustable search radius, time window, and minimum magnitude filter • 15-minute local cache — works offline after first load • Location-aware — shows your distance to each event • Source: USGS Earthquake Hazards Program (public, no auth) • No account, no sign-in, no data collection
