TerraWarn: Disaster Alerts

TerraWarn gives you real-time alerts for earthquakes, wildfires, floods, storms, and other hazards near you — sourced directly from USGS, NASA, and official government agencies, not crowdsourced guesses. When something happens, you'll know immediately, see it on a live map, and know exactly what to do next. LIVE HAZARD ALERTS Get notified the moment a new earthquake, wildfire, flood, hurricane, tornado, or volcanic event is detected near you. Every alert links directly back to its official source — USGS, NASA EONET, or GDACS — so you always know exactly where the data came from. Choose which hazard types matter to you and set a minimum severity, so you only see what's actually relevant. LIVE HAZARD MAP Watch active hazards unfold on a live, continuously-updated map. Switch between standard and satellite view, and turn on fault-line overlays to understand your earthquake risk. Every marker links to full details — magnitude, depth, affected area, and official guidance. FAMILY SAFETY GROUPS Create a family group in seconds and invite the people who matter most with a simple code. When something happens, everyone in the group can mark themselves safe, evacuating, or needing help — and everyone else sees it instantly. No more frantic phone calls trying to reach everyone during a disaster. Anyone in the group can invite others, and you can belong to more than one group — your own family, your partner's family, roommates, whatever makes sense for you. ONE-TAP SOS When every second counts, TerraWarn gets you to help fast — one-tap access to emergency calling and the correct local emergency number for wherever you are in the world, not just your home country. GUIDED EMERGENCY MODE Pick your hazard and TerraWarn walks you through exactly what to do, step by step, with clear do's and don'ts for that specific situation — earthquake, flood, wildfire, hurricane, tornado, and more. FIRST AID & MEDICAL GUIDES Medically-reviewed, offline-available step-by-step guides for the moments that matter most: CPR, severe bleeding, burns, choking (adult, child, and infant), stroke, heart attack, seizures, poisoning, and broken bones. Sourced from the American Red Cross and CDC, and available even without a connection. PREPAREDNESS CHECKLIST & EMERGENCY KIT Build a real household emergency plan with a guided checklist, and track your emergency kit item by item — water, food, first aid supplies, flashlight, radio, documents, and more — so you always know what you're missing before you need it. MEDICAL PROFILE Keep your blood type, allergies, medications, and conditions on hand in one place, ready to show a first responder in an emergency. NEARBY HELP Instantly find the closest shelters, hospitals, pharmacies, fire stations, and police, with real-time directions in whichever maps app you already use. PRIVACY-RESPECTING BY DESIGN Use TerraWarn as a guest and nothing leaves your device — no account required. Creating an account is entirely optional, doesn't require an email address, and you can permanently delete your account and all its data at any time. Location is only used in the moment you ask for nearby hazards or facilities — we don't track you continuously in the background. BUILT FOR EVERYONE TerraWarn is supported by ads shown outside of emergency and safety-critical screens — we don't put ads between you and the help you need. Available in 23 languages. Disasters don't wait, and neither should you. Download TerraWarn and be ready before it happens.
