Risk Overview

About Natural Disaster Risk in Coffee County, Tennessee

Coffee County moderately exceeds state average

Coffee County's composite risk score of 63.52 sits above Tennessee's state average of 52.45, indicating above-average vulnerability to natural disasters. The county's relatively low rating reflects concentrated risk in specific hazard categories rather than uniform exposure across all disaster types.

Upper-middle tier risk among Tennessee counties

With a score of 63.52, Coffee County ranks in the upper-middle range of Tennessee's 95 counties by disaster risk. The county's positioning reflects its central Tennessee location, where certain seismic and storm hazards are naturally amplified.

Higher tornado risk than comparable peers

Coffee County's tornado risk of 86.29 substantially exceeds that of surrounding counties in the region, making severe weather the county's distinguishing hazard characteristic. Its composite score of 63.52 places it among the riskier central Tennessee counties.

Tornadoes and earthquakes threaten residents

Tornado risk (86.29) and earthquake risk (87.37) represent Coffee County's primary concerns, both well above the state average and indicating significant seismic and storm exposure. Flood risk (55.98) ranks third, while wildfire exposure remains minimal at 11.55.

Storm shelter and earthquake insurance essential

Coffee County residents should prioritize a basement safe room or reinforced interior shelter to address the county's exceptionally high 86.29 tornado risk. Standalone earthquake insurance is equally critical given the county's 87.37 seismic risk score.

Risk Advisory: Coffee County

Risk Verdict

At the 64th percentile nationally, Coffee County experiences a manageable level of natural hazard risk that falls below the U.S. median. Coffee County's risk profile calls for targeted preparedness, focusing on the hazard categories that dominate the county's score.

Hazard Breakdown

Earthquake risk is Coffee County's dominant natural hazard, ranked at the 87th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 86th percentile nationally. Additional tracked hazards include flood (56th percentile), hurricane (52th percentile), wildfire (12th percentile).

Preparedness Context

Coffee County's primary hazard, earthquake, ranks at the 87th percentile nationally. Unreinforced masonry structures carry the highest injury risk during seismic events; residents in older buildings should check with their municipality about available seismic retrofit programs. Alongside earthquake exposure, Coffee County's tornado risk at the 86th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. After a major earthquake, Coffee County residents should expect water service disruption for 24 to 72 or more hours. Storing a minimum of one gallon per person per day for three days — before any event — is the most direct preparedness action households can take.

Regional Context

Coffee County falls 11.1 points above Tennessee's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.

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 Coffee County higher risk than average?
Coffee County's composite risk score of 64th percentile is above the Tennessee state average of 53th percentile.
