About Natural Disaster Risk in Perry County, Tennessee

Perry County has very low disaster risk

Safer than Putnam and Rhea counties

Perry County (33.40) presents lower risk than nearby Putnam County (65.84) and Rhea County (49.17), though it faces slightly higher exposure than Pickett County (4.61). The county occupies a relatively safe position in the region's risk hierarchy.

Tornado and earthquake merit attention

Tornado risk (60.15) and earthquake risk (72.49) are Perry County's primary hazards, with flood risk (47.14) presenting a secondary concern. Together, these three hazards account for most of the county's disaster exposure.

Risk Advisory: Perry County

Risk Verdict

Compared to the nation's 3,144 counties, Perry County ranks at the 33th percentile for natural disaster risk — toward the safer end of the spectrum. A preparedness foundation — alert registration, household communication plan, and a basic supply review — costs little and remains valuable even at Perry County's favorable 33th percentile ranking.

Hazard Breakdown

Earthquake risk is Perry County's dominant natural hazard, ranked at the 72th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 60th percentile nationally. Additional tracked hazards include flood (47th percentile), hurricane (42th percentile), wildfire (8th percentile).

Preparedness Context

With earthquake ranked as the top hazard at the 72th percentile nationally, Perry 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 60th percentile nationally is a separate hazard dimension for Perry County that requires different protective strategies from earthquake preparedness. Earthquake insurance in Perry 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

At 19.1 points below the Tennessee state average, Perry County is among the lower-risk counties in the state for natural disaster exposure.
