Risk Overview

About Natural Disaster Risk in Henry County, Ohio

Henry County maintains very low disaster risk

At 33.81, Henry County's composite risk score runs well below the national average and significantly lower than Ohio's 55.03 state average. This very low rating places residents in a relatively protected position nationwide.

Ranks among Ohio's safer counties

Henry County's 33.81 score situates it in the lower half of Ohio's risk distribution, meaning fewer counties are safer statewide. This solid standing reflects moderate to low exposure across most natural hazard types.

Safer than most surrounding counties

Henry County's 33.81 score beats Highland County (43.19), Hocking County (47.30), Huron County (50.29), and Holmes County (60.40), though it trails the exceptional safety of Hardin (24.43) and Harrison (11.42). It occupies a comfortable middle ground in northwest Ohio.

Tornado and flood pose moderate concern

Tornado risk (48.51) and flood risk (55.09) are Henry County's two most significant hazards, each approaching or exceeding state average levels. Earthquake (52.96) and hurricane (36.80) risks are secondary concerns, while wildfire exposure is minimal at 3.47.

Prepare for severe weather and flooding

Standard homeowners insurance forms your foundation, but Henry County residents should specifically ensure flood coverage is in place or understand why it's excluded. A tornado safety plan—identifying a safe room or shelter—and a weather radio provide critical protection given the moderate tornado risk.

Risk Verdict

At the 34th percentile nationally, Henry County experiences relatively limited natural hazard pressure compared to most of the country. At the 34th percentile nationally, Henry County's natural hazard profile is comparatively favorable — community resilience is reinforced when individual households maintain a reviewed emergency plan.

Hazard Breakdown

Flood risk is Henry County's dominant natural hazard, ranked at the 55th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 53th percentile nationally. Additional tracked hazards include tornado (49th percentile), hurricane (37th percentile), wildfire (3th percentile).

Preparedness Context

Henry County sits at the 55th percentile nationally for flood exposure. Knowing your property's flood zone designation — available at FEMA's Flood Map Service Center — is the first step toward understanding actual exposure and insurance options. Alongside flooding, earthquake exposure at the 53th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. Regardless of specific hazard, Henry County households benefit from a practiced communication plan: a designated out-of-state contact and a pre-agreed evacuation destination established before the season's peak risk period.

Regional Context

A composite score 21.2 points below the Ohio state average puts Henry County in a better-than-typical position relative to neighboring counties.
