US Natural Hazard Tracker
10 hazard types · Real-time data from USGS, NOAA/NWS, NIFC, NAC, and Smithsonian GVP
Hazard Map monitors 10 categories of natural hazards across the United States, pulling from authoritative government data feeds updated every 10 minutes to weekly depending on hazard type. All data is sourced from public APIs — no commercial data providers. The interactive map lets you toggle hazard layers, search any city or state, and view detailed dashboards for each hazard type.

About the Data
All data used by Hazard Map is sourced from official US government agencies and nonprofit scientific institutions operating under public data mandates. Sources include the USGS Earthquake Hazards Program, NOAA National Weather Service, NOAA National Hurricane Center, National Interagency Fire Center, National Avalanche Center, Smithsonian Global Volcanism Program, USGS Landslide Hazards Program, NOAA Storm Prediction Center, and the US Drought Monitor.
Data is fetched by automated scripts running on a server and cached locally — the app does not make live API calls during your session. Update timestamps are shown in the app to indicate data freshness.
Not for emergency decision-making. This tool is for general situational awareness only. For life-safety decisions, always consult official NWS alerts at weather.gov, local emergency management, and official agency communications.
