Risk Overview

About Natural Disaster Risk in Perry County, Pennsylvania

Perry County enjoys relatively low disaster risk

Perry County's composite risk score of 53.12 is significantly below Pennsylvania's state average of 67.45 and well below most national benchmarks, placing it in the relatively low-risk category. While the county faces moderate flood risk (69.53) and hurricane exposure (76.14), most other hazards remain well-controlled.

Among Pennsylvania's safer counties

Perry County ranks near the bottom of Pennsylvania's risk scale, with only a handful of counties scoring lower overall. Its 53.12 composite score reflects below-average exposure to tornadoes (31.62), earthquakes (38.71), and wildfires (24.97), making it one of the state's more resilient areas.

Safer than most central Pennsylvania peers

Perry County is significantly less risky than adjacent Northumberland (79.17) and Schuylkill (85.31) counties, and roughly comparable to Snyder County (54.29). Its moderate flood risk (69.53) is lower than Northumberland's and reflects its slightly more inland position away from major river valleys.

Floods and hurricanes are primary concerns

Perry County's top two hazards are flood risk (69.53) and hurricane risk (76.14), both related to Atlantic weather systems and regional precipitation patterns. All other hazards—wildfire (24.97), tornado (31.62), and earthquake (38.71)—score notably low, indicating minimal concern in those areas.

Flood insurance is your key protection

Perry County residents should obtain standalone flood insurance, as it's not included in standard homeowners policies and the county's 69.53 flood risk score justifies the investment. Review your policy annually to ensure coverage limits match current home values and include protection against wind damage from Atlantic storms.

Risk Advisory: Perry County

Risk Verdict

With a national percentile rank of 53th, Perry County faces below-average hazard exposure relative to U.S. counties as a whole. Above-average risk does not mean imminent danger; it signals that informed, hazard-specific preparedness has high value here.

Hazard Breakdown

Hurricane risk is Perry County's dominant natural hazard, ranked at the 76th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 70th percentile nationally. Additional tracked hazards include earthquake (39th percentile), tornado (32th percentile), wildfire (25th percentile).

Preparedness Context

At the 76th percentile nationally for hurricane exposure, Perry County households benefit from reviewing both homeowners and flood insurance coverage before storm season begins — standard policies often exclude storm surge, which is the leading cause of hurricane fatalities. Flood, the county's second-ranked hazard at the 70th percentile nationally, represents an additional preparedness consideration for Perry County independent of hurricane season. Hurricane-force winds cause direct property damage, but storm surge causes the majority of hurricane-related deaths. Perry County households near tidal water or low-elevation areas should verify whether they are in a storm surge risk zone.

Regional Context

Perry County falls 14.3 points below Pennsylvania's typical county risk level, making it one of the safer natural-hazard environments in the state.
