EarthSafe helps you know what to do before, during and after an earthquake. It is free, has no ads, and the parts you need most work without internet. KNOW WHAT IS SHAKING • Earthquakes from AFAD, EMSC and USGS in one list, with the place in your language, the depth, the distance and how strongly each was likely felt where you are • An archive back to 1900: the history of your area, the notable earthquakes, and what has shaken the spot you are standing on • The seismic globe: where the Earth shakes, what is shaking now, a century replayed, and the slabs beneath the surface filtered by years, magnitude and depth ALERTS THAT RESPECT YOUR ATTENTION • Notifications for earthquakes near you, not every earthquake on the planet. You choose the magnitude, the region and the agencies • After a strong earthquake nearby, EarthSafe asks "Are you OK?" so your family hears from you instead of guessing • EarthSafe is not an early-warning system: alerts arrive after an earthquake has been recorded YOUR FAMILY, IN ONE PLACE • Your family circle at a glance: who said they are safe, who needs help, who has not answered • Messages with one-tap replies ("I'm safe", "Stay where you are") and location sharing • Meeting points with directions, and a 60-second family drill WHEN SECONDS COUNT — WORKS OFFLINE • "I'm safe" and "I need help" in one tap • Drop, cover, hold on — indoors, outdoors, in a vehicle or in a high-rise • Torch, siren, messaging nearby phones over Bluetooth when networks are down, and a calm mode that guides your breathing and the next three steps PREPARE AT YOUR OWN PACE • A preparedness checklist that remembers the expiry dates in your kit • Your location risk: the distance to the nearest mapped fault, the last 30 days of earthquakes around you, and the largest on record nearby • Earthquake Captain: answers to nearly fifty safety questions — first aid, building safety, insurance, kits, what to do after — offline, and read aloud if you wish • A weekly preparedness quiz to play with your family ALSO • Home-screen widgets for your city and your readiness • Felt reports, aftershock curves, your seismic identity card, and the time machine: how a historic earthquake would shake you today • English, Turkish and Spanish Data: AFAD (Türkiye), EMSC (CC BY 4.0), USGS and ISC / ISC-GEM. Risk figures are estimates, not official hazard ratings.
