Risk Overview

About Natural Disaster Risk in Bucks County, Pennsylvania

Bucks faces above-average disaster risk

With a composite risk score of 94.78, Bucks County ranks in the relatively high category—well above Pennsylvania's state average of 67.45. This means residents here face meaningfully elevated exposure to multiple natural hazards compared to typical U.S. counties.

Second-riskiest county in Pennsylvania

Bucks County's composite score ranks it second among all 67 Pennsylvania counties for natural disaster risk. Only one other Pennsylvania county faces comparable overall hazard exposure, making Bucks a significant outlier in the state.

Much riskier than surrounding counties

Chester County (91.86) is the only nearby county approaching Bucks's risk level, but even Chester lags by nearly 3 points. Counties to the north and west—Butler, Centre, and Carbon—all score substantially lower, from 59 to 79 points.

Flooding and earthquakes dominate here

Bucks County's flood risk score of 97.11 is exceptionally high and represents the county's most urgent hazard concern. Earthquake risk (93.92) and tornado risk (92.14) also rank well above state averages, creating a compounding exposure that demands preparation across multiple scenarios.

Flood insurance is essential in Bucks

Standard homeowners policies exclude flood damage, making separate flood insurance critical given your county's 97.11 flood risk score. Consider earthquake coverage as well, and review your tornado preparedness plan annually with your family.

Hazard Breakdown

Additional tracked hazards include tornado (92th percentile), hurricane (88th percentile), wildfire (56th percentile).

Preparedness Context

Flood risk is Bucks County's top hazard at the 97th percentile nationally. Households in or near designated flood zones face elevated financial exposure; flood insurance typically requires a 30-day waiting period before it takes effect, so applying before the season is advisable. Secondary earthquake exposure at the 94th percentile adds a second preparedness layer; households should review coverage options and alert sign-up for both hazard types. Households across Bucks County should identify the nearest community shelter and keep a basic emergency kit — water, non-perishable food, medications, flashlight, and battery radio — in a location easy to grab quickly.

Regional Context

Bucks County is 27.3 composite risk points above the Pennsylvania average, indicating that residents face greater natural hazard exposure than most of their in-state neighbors.
