About Alertra
Sub-60s disaster detection and hyper-local alerting. Built for precision and public safety.
🏢 Who We Are
Alertra is built by Ghost Systems, an Arizona-based company focused on weather and natural disaster safety technology. We build tools that help people understand environmental risk before it becomes an emergency.
Alertra ingests real-time seismic data from the U.S. Geological Survey (USGS) and combines it with over 15 years of legacy earthquake records to build localized risk models for communities across the United States. Our threat scores, historical trend charts, and proximity alerts are all derived from this data — updated every 60 seconds.
We also develop BaroBuddy, a barometric pressure tracking app that helps people who are sensitive to weather changes stay ahead of symptoms. Same mission, different signal — giving people the information they need to stay safe and feel better.
