Risk Overview

About Natural Disaster Risk in Hardin County, Ohio

Hardin County faces very low disaster risk

With a composite risk score of 24.43, Hardin County ranks well below the national average and sits significantly safer than Ohio's 55.03 state average. This very low rating means residents face minimal exposure to major natural disasters compared to the typical American county.

Among Ohio's safest counties overall

Hardin County's composite score places it in the safest tier statewide, with only a handful of Ohio counties scoring lower. The county's very low rating reflects relatively modest hazard exposure across all major disaster types.

Safest in its peer group

Hardin County's 24.43 score makes it safer than Harrison County (11.42 is lower, but Harrison is an outlier), Henry County (33.81), Highland County (43.19), and Hocking County (47.30). Its position as one of northwest Ohio's most resilient counties offers residents genuine peace of mind.

Earthquakes and hurricanes pose mild concern

Earthquake risk (48.85) and hurricane risk (43.60) represent Hardin County's two highest hazard scores, though both remain moderate in absolute terms. Flooding (40.20) and tornado risk (36.29) are also present but manageable, while wildfire risk is negligible at just 1.27.

Basic coverage keeps you prepared

Even low-risk counties benefit from standard homeowners insurance and a basic emergency kit covering water and medications. Consider a conversation with your insurance agent about flood and earthquake options, especially if your property is near a waterway.

Risk Verdict

Hardin County carries a low natural disaster risk burden, scoring at the 24th percentile under the FEMA National Risk Index. A 24th percentile score positions Hardin County among the nation's lower-risk counties, a genuinely favorable outcome — one that simple, low-cost preparedness habits can reinforce further.

Hazard Breakdown

Earthquake risk is Hardin County's dominant natural hazard, ranked at the 49th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 44th percentile nationally. Additional tracked hazards include flood (40th percentile), tornado (36th percentile), wildfire (1th percentile).

Preparedness Context

Hardin County's primary hazard, earthquake, ranks at the 49th percentile nationally. Unreinforced masonry structures carry the highest injury risk during seismic events; residents in older buildings should check with their municipality about available seismic retrofit programs. Hurricane at the 44th percentile nationally is a separate hazard dimension for Hardin County that requires different protective strategies from earthquake preparedness. After a major earthquake, Hardin County residents should expect water service disruption for 24 to 72 or more hours. Storing a minimum of one gallon per person per day for three days — before any event — is the most direct preparedness action households can take.

Regional Context

Compared to the Ohio county average, Hardin County's composite score runs 30.6 points lower — a gap that reflects the county's relatively modest hazard profile within its state context.
