About Natural Disaster Risk in Campbell County, Wyoming

Campbell ranks among Wyoming's riskiest counties

Campbell County's composite risk score of 56.14 rates as relatively low but sits 48% above Wyoming's state average of 37.86. The county faces notably elevated wildfire exposure (92.91) and meaningful earthquake risk (72.26).

Second-highest risk in the state

Among Wyoming's 23 counties, Campbell ranks near the top for disaster vulnerability. Its composite score of 56.14 reflects severe wildfire risk (92.91) and above-average exposure to tornadoes and earthquakes.

Significantly riskier than surrounding areas

Campbell County's risk profile stands well above neighboring Big Horn County (31.14) and exceeds the state average by substantial margins. The county's extreme wildfire exposure (92.91) represents one of the highest in Wyoming.

Catastrophic wildfire risk dominates Campbell's profile

Wildfire risk scores an exceptional 92.91—among the state's worst—reflecting vast grassland and forest exposure. Earthquake risk (72.26) and tornado risk (46.34) create additional hazard layers that residents must plan for separately.

Wildfire insurance is non-negotiable here

Campbell County residents should verify that wildfire and brush coverage is explicitly included in their homeowners policies and maintain aggressive defensible space maintenance. Earthquake insurance and a solid emergency plan become essential given the county's multi-hazard exposure profile.

Risk Verdict

At the 56th percentile nationally, Campbell County experiences a manageable level of natural hazard risk that falls below the U.S. median. Campbell County's risk profile calls for targeted preparedness, focusing on the hazard categories that dominate the county's score.

Hazard Breakdown

Preparedness Context

Wildfire ranks as Campbell County's primary hazard at the 93th percentile nationally. For Campbell County households in high-WUI areas, go-bag readiness — the ability to leave within 15 minutes — is more important than shelter-in-place planning for most residential properties. The county's earthquake exposure at the 72th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Campbell County county's local emergency management office publishes community-specific wildfire risk assessments and evacuation zone maps; households should review their zone assignment and sign up for zone-specific alerts.

Regional Context

Campbell County falls 18.3 points above Wyoming's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Campbell County higher risk than average?
Campbell County's composite risk score of 56th percentile is above the Wyoming state average of 38th percentile.
