About Natural Disaster Risk in Marion County, West Virginia

Marion County's disaster risk stays moderate

Marion County's composite risk score of 71.50 exceeds West Virginia's state average of 49.21, placing it in the relatively low risk category. This reflects significant flood and hurricane exposure tempered by low wildfire and tornado threats.

Marion ranks in upper-middle tier for risk

Marion County scores 71.50 on the composite disaster risk scale, placing it solidly in the middle-to-upper range of West Virginia's 55 counties. The county's risk profile is anchored by flood vulnerability rather than spread across multiple hazard types.

Marion's risk closely mirrors Harrison County

Marion County's composite score of 71.50 nearly matches Harrison County's 73.60, with both counties facing similar flood exposure (Marion 85.69, Harrison 86.70) and hurricane risk (Marion 58.78, Harrison 60.58). Marion's slightly lower overall score reflects marginally better performance across most hazard categories.

Flooding and hurricanes threaten Marion County

Flooding dominates Marion County's hazard landscape with a risk score of 85.69, affecting numerous communities and stream corridors. Hurricane risk ranks second at 58.78, while wildfire (30.18), tornado (30.88), and earthquake (42.08) exposures remain moderate.

Flood insurance is Marion's first priority

Marion County's 85.69 flood risk makes flood insurance absolutely essential and should form the foundation of your home protection plan. Add comprehensive wind and hail coverage to address the 58.78 hurricane exposure, and consider earthquake coverage if your home sits near seismic zones.
