QuakeLens: Earthquake Monitor

QuakeLens watches over the places that matter to you — where your family lives, not just where your phone happens to be. Register the locations you care about. QuakeLens monitors the seismic zones covering them, around the clock, using each region's national earthquake catalogs. WHAT IT DOES • Live status for every zone: typical, busy, or under statistical alert • Alerts when recent activity is measurably above the zone's own baseline • Aftershock-sequence tracking after significant earthquakes, with caution periods • Hourly and 28-day activity charts with alert periods marked • Radar replay: play the zone map back like weather radar — the last 24 hours live, or the 48 hours around a notable quake: the before, the strike and the aftermath • Honest report cards: for past earthquakes in each zone, see what the detector caught — and what it missed • Alert history: every alert, caution period and sequence in your zones — a growing record you can revisit any time • Home screen widgets, notifications in your language, iCloud sync WHAT IT IS NOT Earthquakes cannot be predicted — by anyone. QuakeLens never claims otherwise. What it measures is elevated statistical probability: periods when small-quake activity is unusually high, similar to how seismologists describe aftershock risk. Most alerts are not followed by a damaging quake, and quiet activity does not mean safe. QuakeLens is a lens on the data, not a crystal ball. COVERAGE Monitored zones across Türkiye, Japan, the US, Italy, Greece, Chile, Colombia, New Zealand and more countries — each calibrated against decades of that region's own earthquake history. Coverage keeps growing, and new zones arrive without an app update. QUAKELENS WATCH The free app shows the full live status of one location — alerts are never hidden. QuakeLens Watch (monthly, yearly with a one-week free trial, or a one-time lifetime purchase) adds push notifications, unlimited locations, hourly charts, radar replay and widgets.
