Risk Overview
About Natural Disaster Risk in Kanawha County, West Virginia
Kanawha County faces significantly elevated disaster risk
Kanawha County's composite risk score of 94.53 places it nearly twice West Virginia's state average of 49.21 and squarely in the relatively high risk category. This score reflects substantial exposure to multiple hazard types, making Kanawha one of the state's most disaster-prone counties.
Kanawha County ranks among West Virginia's highest-risk
Kanawha County stands out as the highest-risk county in this eight-county analysis group, with a composite score of 94.53 that far exceeds the state average. The county faces serious vulnerability across flood, wildfire, earthquake, and hurricane hazards.
Kanawha's risk dramatically exceeds surrounding counties
Kanawha County's 94.53 composite score towers over Harrison County's 73.60 and Logan County's 79.23, driven by exceptional flood risk (97.90) that tops most peers. Its 76.30 earthquake risk also surpasses all neighboring counties in this group, creating a compound vulnerability profile.
Flooding poses an exceptional, immediate threat
Kanawha County faces an extraordinary flood risk of 97.90, placing it in the highest-danger category for water-related disasters in the state. Wildfire exposure ranks second at 61.55, earthquake risk third at 76.30, and hurricane risk fourth at 64.41—a dangerous combination of overlapping hazards.
Flood and earthquake insurance are non-negotiable
Kanawha County's 97.90 flood risk score demands immediate action: flood insurance is absolutely essential and should be treated as a core protection, not an option. Couple this with earthquake coverage for your 76.30 seismic exposure, and add comprehensive wind/hail policies to address wildfire and hurricane threats.

Alongside flooding, earthquake exposure at the 76th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. A waterproof container for documents (insurance policies, ID, prescriptions) and a clear household communication plan for when phone networks are congested are the two highest-value low-cost preparedness steps for Kanawha County households.
