Risk Overview
About Natural Disaster Risk in Teton County, Montana
Teton's risk remains below national average
Teton County's composite risk score of 19.02 with a Very Low rating places it well below the typical U.S. county's exposure to natural disasters. Your risk profile is driven primarily by wildfire and earthquake hazards rather than the high-impact floods or hurricanes seen in other regions.
Mid-tier risk within Montana
At 19.02, Teton's composite risk score is below Montana's state average of 33.31, ranking it among the safer counties statewide. However, your earthquake risk (53.69) stands notably higher than many neighboring counties, reflecting the region's geological character.
Higher earthquake risk than peers
Teton County's earthquake risk of 53.69 significantly exceeds nearby Sweet Grass (34.86) and Toole (29.87), reflecting its proximity to seismic zones. Overall, your total composite risk of 19.02 remains moderate compared to your neighbors along the Rocky Mountain Front.
Wildfire and earthquakes dominate
Wildfire risk at 73.51 and earthquake risk at 53.69 are your primary hazard exposures, while flood (32.19) and tornado (5.03) risks remain minimal. The combination of fire season threats and occasional seismic activity requires dual-focused preparedness planning.
Bundle fire and earthquake coverage
Your homeowner's policy should explicitly cover both wildfire damage and earthquake damage, as standard policies often exclude these perils. Securing these coverages protects your investment against Teton's two most significant natural hazards.

Hazard Breakdown

Preparedness Context
At the 74th percentile nationally for wildfire, Teton County residents should verify whether their insurance policy includes replacement cost coverage for structures and whether the insurer still writes new policies in this fire-risk zone. Alongside wildfire, earthquake at the 54th 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 Teton County residents can use to stay ahead of rapidly changing wildfire conditions.
Regional Context
Teton County is 14.3 composite risk points below the Montana state mean, meaning most other Montana counties face higher natural hazard exposure.
