Alertra

Alertra is a real-time disaster alert platform designed to deliver faster, more precise warnings than traditional government systems. Most emergency alerts today are delayed, overly broad, and often irrelevant to a user’s exact location. Alertra solves this by monitoring multiple disaster sources simultaneously, including earthquakes, wildfires, tornadoes, floods, hurricanes, and tsunamis, and sending push notifications within 60 seconds of detection. The platform pulls raw data directly from trusted sources such as USGS, NOAA, NASA FIRMS, and the National Hurricane Center, eliminating intermediary delays. Using advanced polygon intersection logic from the National Weather Service, Alertra pinpoints alerts to specific ZIP codes rather than entire counties or states, reducing noise and false alarms. With coverage across more than 30,000 ZIP codes in the United States, users receive only relevant, hyperlocal alerts. Alertra requires no account to start and includes a live city threat board for monitoring risks across multiple locations. Built for people living in high-risk areas, it provides faster, smarter, and more actionable disaster awareness.
