Hazard Breakdown
Earthquake risk is Trigg County's dominant natural hazard, ranked at the 85th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 70th percentile nationally.

Preparedness Context
With earthquake ranked as the top hazard at the 85th percentile nationally, Trigg 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 70th percentile nationally is a separate hazard dimension for Trigg County that requires different protective strategies from earthquake preparedness. Earthquake insurance in Trigg 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.

Trigg County sits within 4.2 composite points of the Kentucky state average, suggesting the county's hazard exposure is representative of the broader regional pattern.
