Risk Overview

About Natural Disaster Risk in Clarion County, Pennsylvania

Clarion County has very low disaster risk

Clarion County's composite risk score of 30.03 ranks it in the very low category—37 points below Pennsylvania's state average of 67.45. This rural northwestern county enjoys one of the lowest natural disaster exposure profiles in the state.

Among Pennsylvania's safest counties

Clarion County ranks near the bottom of Pennsylvania's 67 counties for overall disaster risk. Only Cameron County scores lower, making Clarion one of the genuinely low-risk areas in the commonwealth.

Much safer than surrounding areas

Clarion County's 30.03 score is far below Butler County (79.26) to the southeast and well below Centre and Cambria counties to the east. This geographic pocket of low risk is a distinctive advantage.

Flooding poses the main hazard

Clarion County's flood risk of 52.19 stands as its only moderate hazard score; all other risks fall well below 35. While flooding warrants attention, the county faces genuinely limited natural disaster exposure overall.

Basic insurance coverage typically adequate

Clarion County's very low overall risk means standard homeowners insurance provides sufficient protection for most residents. Evaluate flood risk on your specific property and maintain basic emergency supplies and a family communication plan.

Risk Verdict

Clarion County's overall natural disaster score at the 30th percentile puts it well below the national median for hazard exposure. The 30th percentile national ranking is one lens; Clarion County residents also benefit from reviewing which specific hazard types drive the county's composite score and preparing accordingly.

Hazard Breakdown

Hurricane risk is Clarion County's dominant natural hazard, ranked at the 63th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 52th percentile nationally. Additional tracked hazards include earthquake (32th percentile), tornado (29th percentile), wildfire (16th percentile).

Preparedness Context

Hurricane exposure at the 63th percentile nationally makes Clarion County a county where pre-season preparedness — not storm-day preparation — determines outcomes. Clarion County evacuation decisions under a watch or warning benefit from prior planning, not routes improvised under time pressure. Clarion County's flood exposure at the 52th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. Clarion County residents benefit from registering with the county's special-needs evacuation registry if household members have mobility limitations, require electricity-dependent medical equipment, or cannot self-evacuate — registration in advance of storm season is required.

Regional Context

Clarion County's composite risk score sits 37.4 points below the Pennsylvania county average, reflecting a more favorable hazard environment than the state typical.
