About Natural Disaster Risk in Teton County, Idaho
Teton County faces very low disaster risk
With a composite risk score of 29.45, Teton County ranks in the lowest tier of U.S. counties for natural disaster exposure. This score falls well below the national average, positioning residents in one of America's safer regions for combined hazard risk.
Safest county in Idaho overall
Teton County's composite risk of 29.45 ranks it as the lowest-risk county in Idaho, significantly below the state average of 38.51. Among all 44 Idaho counties, Teton stands out as the most resilient to multi-hazard disaster risk.
Much safer than nearby counties
Teton County's 29.45 score compares favorably to neighboring Valley County (55.63) and Twin Falls County (46.95), making it notably less exposed to combined natural disasters. Washington County, its closest competitor, still scores higher at 30.31.
Earthquakes and wildfires pose most concern
Teton County faces meaningful earthquake risk (78.34) despite its overall low rating, reflecting its proximity to seismic zones. Wildfire risk (90.87) also demands attention, though flood and tornado risks remain minimal at 27.96 and 10.56 respectively.
Prioritize earthquake and wildfire coverage
Standard homeowners policies exclude earthquake and wildfire damage, making separate coverage critical for Teton County residents. Given your county's elevated seismic activity and wildfire exposure, adding these protections is a practical investment in home security.

Hazard Breakdown
Wildfire risk is Teton County's dominant natural hazard, ranked at the 91th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 78th percentile nationally. Additional tracked hazards include flood (28th percentile), tornado (11th percentile).
Preparedness Context
Teton County's dominant hazard is wildfire, ranked at the 91th percentile nationally. Maintaining at least 30 feet of lean, clean vegetation around structures in Teton County and keeping gutters clear of debris significantly reduces ignition risk from wind-driven embers. The county's earthquake exposure at the 78th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Teton County's households benefit from reviewing homeowners insurance before fire season, specifically whether the policy covers replacement cost rather than actual cash value, and whether it includes additional living expenses if displacement is required.
Regional Context
A composite score 9.1 points below the Idaho state average puts Teton County in a better-than-typical position relative to neighboring counties.
