React before it strikes.
Alertra pulls raw data straight from USGS, NOAA, and NASA—bypassing the middleman to give you the earliest possible warning.
Hyperlocal Radius
NWS polygon warnings pinpointed to your exact street, outperforming vague county-wide sirenes.
Faster Than FEMA
Our direct-to-API pipeline sends push notifications in under 60 seconds of a detected rupture.
Total Coverage
Monitor earthquakes, tornadoes, hurricanes, wildfires, and floods simultaneously from one hub.
How Alertra Tracks Earthquakes
Our platform connects directly to the USGS (United States Geological Survey) seismic data feeds. By processing raw shake data in real-time without middleman delays, Alertra can identify significant ruptures and calculate hyper-local threat radii instantly.
- ✓ Direct API integration with USGS sensors
- ✓ Live magnitude and wave depth calculation
- ✓ Instant push alerts to affected ZIP codes before shaking arrives

// About Alertra
One platform. Every disaster.
Disaster data is scattered across USGS, NOAA, NASA, and dozens of regional agencies — each with different formats, delays, and coverage gaps. Alertra was built to fix that. One centralized platform that unifies every major threat type into a single, real-time feed for your exact location.
