Risk Overview
About Natural Disaster Risk in Teton County, Wyoming
Teton's natural hazard exposure exceeds average
Teton County scores 70.64 on the composite risk index, earning a Relatively Low rating but placing it significantly above the national average. This elevated score reflects Teton's mountainous terrain and proximity to major geological and wildfire hazard zones. Despite the "Relatively Low" designation, Teton residents face above-average exposure compared to most U.S. counties.
Among Wyoming's highest-risk counties
Teton's composite score of 70.64 ranks it as one of Wyoming's most hazard-exposed counties, nearly double the state average of 37.86. Only Sheridan County (65.20) approaches Teton's risk level among Wyoming's counties. Teton's position reflects its location at the intersection of seismic and wildfire hazard zones in northwestern Wyoming.
Teton faces steeper risks than nearby counties
Teton (70.64) carries substantially higher risk than neighboring Sublette County (21.63) and Washakie County (24.36), reflecting its higher elevation and more active geological setting. Only Sheridan County (65.20) presents a comparable risk profile in the region. Teton's mountainous terrain and wildland-urban interface create distinctly elevated hazard exposure.
Earthquakes and wildfires lead Teton's hazards
Teton County's earthquake risk reaches 87.12, the highest hazard score and reflecting the county's location in an active seismic region near major fault systems. Wildfire risk scores 90.65, capturing the region's extensive forest and grassland fire exposure. Flood risk (34.73) and tornado risk (19.40) present much lower concerns.
Earthquake and wildfire coverage essential
Teton residents must obtain earthquake insurance separately from their homeowners policy, given the county's exceptional 87.12 earthquake risk score. Wildfire coverage is equally critical—ensure your policy explicitly covers wildfire damage and consider higher deductibles to enable broader coverage. Professional seismic and wildfire risk assessments can identify specific vulnerabilities in your home's construction and location.
