Risk Overview

About Natural Disaster Risk in Preble County, Ohio

Preble ranks as relatively low-risk

Preble County's composite risk score of 43.29 earns a "Relatively Low" rating, placing it below the national disaster risk average. The county experiences fewer widespread natural hazards than most U.S. regions.

Below average for Ohio overall

At 43.29, Preble County scores well below Ohio's state average of 55.03, making it one of the state's safer counties. This 12-point advantage reflects notably lower exposure to multiple hazard types.

Tied with Pike, safer than Pickaway

Preble (43.29) essentially matches Pike County's risk level while significantly outperforming Pickaway (50.92) and Putnam (32.86) in southwestern Ohio. Its balanced risk profile makes it one of the region's more protected counties.

Tornadoes pose Preble's main threat

Tornado risk dominates Preble County at 76.65, making it the county's most significant natural hazard—significantly above Ohio's typical patterns. Earthquake risk at 63.17 ranks second, though less immediately threatening than spring storms.

Prepare for severe spring weather

With tornado risk at 76.65, develop a family tornado plan and identify safe shelter in your home—a basement or interior room away from windows. Ensure your homeowners insurance covers wind and hail damage, common tornado-related losses.

Risk Verdict

At the 43th percentile nationally, Preble County experiences a manageable level of natural hazard risk that falls below the U.S. median.

Hazard Breakdown

Tornado risk is Preble County's dominant natural hazard, ranked at the 77th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 63th percentile nationally. Additional tracked hazards include flood (51th percentile), hurricane (28th percentile), wildfire (14th percentile).

Preparedness Context

Preble County's primary hazard, tornado, ranks at the 77th percentile nationally. In Preble County, mobile homes and manufactured housing face significantly higher tornado risk than site-built structures; residents in these homes should identify the nearest permanent community shelter in advance. The secondary earthquake hazard at the 63th percentile nationally adds seasonal complexity to Preble County's preparedness calendar, since earthquake and tornado risk often peak at different points in the year. The highest-risk window for tornado fatalities is overnight, when Preble County residents may be asleep. A NOAA weather radio with overnight alert capability is the single most impactful low-cost preparedness step available to Preble County households.

Regional Context

Compared to the Ohio county average, Preble County's composite score runs 11.7 points lower — a gap that reflects the county's relatively modest hazard profile within its state context.
