Risk Overview

About Natural Disaster Risk in Crockett County, Tennessee

Crockett's Risk: In Line With Nation

Crockett County scores 52.58 on composite risk, earning a Relatively Low rating that sits just slightly above the national average. This places the county in a safer position than many parts of the country, though local hazards still demand attention.

Middle of the Pack in Tennessee

With a composite risk score of 52.58, Crockett ranks near Tennessee's state average of 52.45, putting it squarely in the middle tier of county risk statewide. Neither among the state's most vulnerable nor safest counties, Crockett reflects typical Tennessee disaster exposure.

Safer Than Some Western Neighbors

Crockett's risk profile sits below Dyer County (86.58) and Fayette County (75.95), but above DeKalb County (25.48) and Decatur County (38.42). The variation across West Tennessee highlights how quickly disaster risk can shift between adjacent communities.

Earthquakes and Tornadoes Lead Threats

Crockett faces exceptional earthquake risk at 93.67—among the highest in its region—and elevated tornado risk at 55.15. Flood risk remains manageable at 14.06, while wildfire exposure is quite low at 7.79.

Earthquake Coverage Deserves Priority

Standard homeowners policies exclude earthquake damage, making separate coverage essential given Crockett's 93.67 earthquake risk score. Ensure your tornado preparedness plan is current and consider coverage for storm-related losses.

Risk Advisory: Crockett County

Risk Verdict

Crockett County has a below-average natural disaster risk profile, scoring at the 53th percentile nationally under FEMA's National Risk Index. Households in Crockett County benefit from knowing which individual hazard types — flood, wildfire, tornado, or hurricane — are the primary contributors.

Hazard Breakdown

Earthquake risk is Crockett County's dominant natural hazard, ranked at the 94th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 55th percentile nationally. Additional tracked hazards include hurricane (47th percentile), flood (14th percentile), wildfire (8th percentile).

Preparedness Context

Earthquake risk is Crockett County's leading natural hazard, ranked at the 94th percentile nationally. Securing tall furniture, water heaters, and bookcases to walls with anti-tip hardware is among the simplest and most effective life-safety measures households can take. Tornado at the 55th percentile nationally is a separate hazard dimension for Crockett County that requires different protective strategies from earthquake preparedness. Crockett County residents should locate the main gas shutoff valve and keep an appropriate wrench nearby — gas leaks cause a significant share of earthquake-related injuries and fires, and the shutoff step is safe to take immediately after shaking stops.

Regional Context

At just 0.1 composite points from the Tennessee average, Crockett County's natural disaster risk is closely in line with its in-state peers.
