Earthquakes and wildfires dominate Fremont's threats
Earthquake risk scores 86.16—the highest in Wyoming—reflecting the county's proximity to the Teton-Gros Ventre seismic belt. Wildfire risk (92.56) ranks among the state's most severe, and flood risk (66.51) adds significant secondary exposure.

Alongside wildfire, earthquake at the 86th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. Local USFS or Cal Fire (where applicable) fire risk maps and seasonal Red Flag Warning alerts from the National Weather Service are two free resources Fremont County residents can use to stay ahead of rapidly changing wildfire conditions.
