Risk Overview

About Natural Disaster Risk in Blount County, Tennessee

Blount County's Risk Above National Average

Blount County scores 74.17 on composite natural disaster risk, earning a Relatively Low rating that slightly exceeds the national average. The county's mountainous terrain drives elevated earthquake exposure (93.10), the highest in Tennessee, alongside significant flood and wildfire vulnerability.

How Blount Ranks Among Tennessee Counties

Blount County's 74.17 score significantly exceeds Tennessee's state average of 52.45, placing it among the state's higher-risk counties. The county's earthquake risk (93.10) stands as the highest in Tennessee, reflecting its proximity to major fault systems in the Great Smoky Mountains region.

Comparing Risk to Neighbors

Blount County faces comparable risk to Anderson County (73.19) and Bradley County (73.41), forming a cluster of high-risk eastern Tennessee counties. The county's mountainous position distinguishes it from lower-risk neighbors like Benton County (39.06) and Cannon County (22.90).

Your Biggest Natural Disaster Risks

Earthquakes (93.10) dominate Blount County's hazard profile—the state's highest exposure—followed by significant flood (74.01) and wildfire (69.43) risks. The county's Great Smoky Mountains location creates overlapping seismic, water, and fire vulnerabilities that require multi-layered preparedness.

Protect Your Home in Blount County

Blount County residents must prioritize earthquake insurance and structural reinforcement—a necessity given the state's highest seismic risk. Flood and wildfire insurance are equally essential; properties in mountain valleys and wildland-urban interface zones face compounded exposure requiring comprehensive coverage.

Risk Advisory: Blount County

Risk Verdict

Blount County's FEMA risk score places it at the 74th 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 Blount County's dominant natural hazard, ranked at the 93th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 74th percentile nationally. Additional tracked hazards include wildfire (69th percentile), tornado (67th percentile), hurricane (56th percentile).

Preparedness Context

With earthquake ranked as the top hazard at the 93th percentile nationally, Blount County residents benefit from reviewing homeowners insurance: standard policies rarely cover earthquake damage, and separate earthquake insurance must be purchased before an event. Flood at the 74th percentile nationally is a separate hazard dimension for Blount County that requires different protective strategies from earthquake preparedness. Earthquake insurance in Blount 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 21.7 composite points below Blount County's score, a gap that reflects the county's elevated position in the state's hazard distribution.
