Risk Overview

About Natural Disaster Risk in Carter County, Tennessee

Carter County's risk exceeds state average

Carter County's composite risk score of 63.17 places it above Tennessee's state average of 52.45, signaling above-average vulnerability to multiple hazard types. The county experiences a relatively low overall rating despite this score, reflecting Tennessee's generally elevated disaster exposure across most regions.

Mid-range risk among Tennessee counties

Carter County ranks in the middle-upper range of Tennessee's 95 counties by composite risk, driven significantly by flood and wildfire vulnerabilities. The county's position reflects its mountainous terrain in East Tennessee, where water and forest hazards converge.

Higher flood risk than neighboring Cocke County

Carter County's flood risk of 77.39 substantially exceeds that of adjacent Cocke County (68.48), despite both counties sitting in the Appalachian region. Its wildfire risk of 60.78 similarly exceeds Cocke County's 61.77, placing Carter in a notably vulnerable position for water and forest hazards.

Floods and wildfires pose primary threats

Flood risk dominates at 77.39 and wildfire risk at 60.78, both substantially above Tennessee's state average and reflecting the county's mountain valleys and forested terrain. Earthquake risk (70.58) and tornado risk (45.42) remain secondary concerns but still warrant preparedness planning.

Flood insurance is non-negotiable here

Carter County's 77.39 flood risk makes federal flood insurance not just recommended but critical—particularly for properties in valley areas or near waterways. Defensible space management around your home (clearing dead vegetation and branches) is equally important given the county's 60.78 wildfire risk.

Risk Advisory: Carter County

Risk Verdict

Carter County has a below-average natural disaster risk profile, scoring at the 63th percentile nationally under FEMA's National Risk Index. Households in Carter County benefit from knowing which individual hazard types — flood, wildfire, tornado, or hurricane — are the primary contributors.

Hazard Breakdown

Flood risk is Carter County's dominant natural hazard, ranked at the 77th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 71th percentile nationally. Additional tracked hazards include wildfire (61th percentile), hurricane (52th percentile), tornado (45th percentile).

Preparedness Context

Carter County's top natural hazard is flood risk, ranked at the 77th percentile nationally. Homeowners here should confirm whether they are in a FEMA-designated flood zone and check if standard homeowners insurance covers flood damage — it typically does not. Alongside flooding, earthquake exposure at the 71th percentile means households benefit from a multi-hazard preparedness plan rather than focusing on flood alone. For most Carter County households, the highest-return preparedness step is storing critical documents in digital cloud backup combined with a pre-designated family meeting point if communication is disrupted.

Regional Context

Carter County's composite risk score sits 10.7 points above the Tennessee county average, placing it among the more hazard-exposed counties in the state.

How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Carter County higher risk than average?
Carter County's composite risk score of 63th percentile is above the Tennessee state average of 53th percentile. This elevated risk is driven by flooding exposure (77th percentile), along with earthquake and wildfire and hurricane risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
