Risk Overview

About Natural Disaster Risk in Franklin County, Tennessee

Franklin County's risk sits near national average

Franklin County's composite risk score of 57.51 places it in the Relatively Low category, slightly above the national average for many counties. The county faces meaningful exposure to tornadoes and earthquakes despite lower wildfire risk than Tennessee's western regions.

Middle-of-pack risk for Tennessee

Franklin County's 57.51 score ranks it above the state average of 52.45, positioning it as a moderate-risk county within Tennessee. Its tornado risk (77.39) and earthquake risk (80.79) pull the overall score upward, while wildfire risk remains comparatively low at 17.27.

More at-risk than Giles, safer than Gibson

Franklin County's risk profile falls between its neighbors: slightly lower than Giles County (60.94) but considerably lower than Gibson County (85.94) to the northwest. Its composite score of 57.51 makes it representative of South-Central Tennessee's moderate hazard exposure.

Tornadoes and earthquakes are primary concerns

Tornado risk dominates at 77.39, reflecting Franklin County's location in Tennessee's tornado corridor where spring and early summer storms frequently develop. Earthquake risk (80.79) ranks nearly as high, tied to proximity to the Cumberland Plateau fault system and seismic activity in the region.

Prioritize tornado and earthquake coverage

Homeowners should ensure policies include tornado and hail damage protection, and consider a safe room or reinforced shelter for severe weather events. Earthquake coverage is often an optional add-on; review your policy to confirm whether structural damage from seismic activity is protected.

Risk Verdict

Franklin County's FEMA risk score places it at the 58th 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

Earthquake risk is Franklin County's dominant natural hazard, ranked at the 81th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 77th percentile nationally. Additional tracked hazards include flood (58th percentile), hurricane (47th percentile), wildfire (17th percentile).

Preparedness Context

With earthquake ranked as the top hazard at the 81th percentile nationally, Franklin County residents benefit from reviewing homeowners insurance: standard policies rarely cover earthquake damage, and separate earthquake insurance must be purchased before an event. Tornado at the 77th percentile nationally is a separate hazard dimension for Franklin County that requires different protective strategies from earthquake preparedness. Earthquake insurance in Franklin County is typically offered as a separate policy — standard homeowners coverage excludes ground movement. Reviewing this gap and comparing policy options before an event is a financial preparedness step with potentially large consequences.

Regional Context

The Tennessee county average is 5.1 composite points below Franklin County's score, a gap that reflects the county's elevated position in the state's hazard distribution.

Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Franklin County higher risk than average?
Franklin County's composite risk score of 58th percentile is above the Tennessee state average of 53th percentile.
