Risk Overview

About Natural Disaster Risk in Carbon County, Pennsylvania

Carbon faces below-average risk overall

Carbon County's composite risk score of 59.41 places it in the relatively low category, nearly 8 points below Pennsylvania's state average of 67.45. While the county experiences some natural hazard exposure, it ranks among the safer regions statewide.

Lower-risk positioning in Pennsylvania

Carbon County ranks in the lower-risk half of Pennsylvania's 67 counties for disaster exposure. Its score reflects moderate hazard exposure without the elevated vulnerability seen in higher-risk counties.

Safer than most nearby counties

Carbon County's 59.41 score is lower than Cambria (76.43), Centre (67.97), and Butler (79.26) to the west. It sits higher than only Clarion County (30.03) and Cameron County (12.63) among the broader region.

Flooding and hurricanes lead concerns

Carbon County's flood risk of 67.53 and hurricane risk of 73.13 are its two highest hazard exposures. While tornado risk (37.88) and earthquake risk (46.60) remain relatively modest, water-related threats deserve primary planning attention.

Flood insurance should be prioritized

With a flood risk score of 67.53, Carbon County residents should secure standalone flood insurance as a core protection. Verify that your homeowners policy covers wind damage and maintain clear drainage around your property.

Risk Advisory: Carbon County

Risk Verdict

Carbon County's FEMA risk score places it at the 59th percentile nationally, indicating lower-than-typical exposure for a U.S. county. A moderate composite score often means one or two hazard categories are doing the heavy lifting — knowing which ones matters for preparation.

Hazard Breakdown

Hurricane risk is Carbon County's dominant natural hazard, ranked at the 73th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 68th percentile nationally. Additional tracked hazards include earthquake (47th percentile), wildfire (41th percentile), tornado (38th percentile).

Preparedness Context

With hurricane ranked at the 73th percentile nationally, Carbon County sits in a zone where multi-day supply readiness matters: grid outages after landfalling storms can last one to three weeks in heavily affected areas. Carbon County's flood exposure at the 68th percentile nationally adds a hazard layer that can persist or intensify after hurricane-force winds have passed, particularly in low-lying inland areas. Insurance gaps are the most common post-hurricane financial shock: standard homeowners policies typically exclude flood damage and may have a separate wind deductible. Carbon County households benefit from a pre-season insurance review confirming both wind and flood coverage.

Regional Context

At 8.0 points below the Pennsylvania state average, Carbon County is among the lower-risk counties in the state for natural disaster exposure.
