Deprem — Live Earthquakes
Alerts, maps and drills
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
Earthquakes in Turkey and worldwide from AFAD, Kandilli, EMSC and USGS in one place, with alerts by the shaking expected at your places.
Follow earthquakes in Turkey and around the world, live. Deprem merges data from AFAD, Kandilli Observatory, EMSC and USGS into one catalogue, shows every agency's magnitude side by side and adds new earthquakes within seconds.
PERSONAL ALERTS
You are alerted by the shaking expected where you are and at your saved place, not by magnitude; when the expected intensity (MMI) crosses your level you get a time-sensitive notification.
MAP AND DETAIL
• Clustered earthquake map with expected intensity rings and active faults (GEM)
• Source comparison, revisions and the expected intensity where you are
• Aftershock probabilities (Reasenberg–Jones)
• Felt reports and statistics
SAFETY
• Send "I'm safe" to your family with one tap
• Nearby assembly areas, also without internet
• Earthquake drill: see how a real detection and a drill alert work
TOOLS
• A loud whistle to call for help when trapped
• Flashlight and SOS in Morse code
• Emergency kit checklist and a family emergency plan
• 112 and other emergency numbers, before/during/after guides
• Sourced guide articles, readable offline
STATION MODE
A charging, still iPhone becomes an earthquake sensor. When it detects shaking it sends only a short summary. Community detection is experimental and currently runs in shadow mode.
WIDGETS AND SHORTCUTS
Home and lock screen widgets, Live Activity, Control Center buttons, Siri shortcuts and an Apple Watch app.
DEPREM PRO
Safety is always free: live data, list and map, alerts, the drill, I'm safe, assembly areas, all tools and the guides. The optional Deprem Pro funds the servers and the detection algorithm and adds unlimited places with their own alert levels for your family's cities, full history and advanced statistics (Gutenberg–Richter b-value, energy, depth, CSV), the full aftershock forecast, widget settings and alternative app icons. Monthly, annual (1-week free trial) or lifetime.
Deprem is not an official warning system. AFAD is the official authority for earthquakes in Turkey.
