Risk Verdict

Bradley County sits below the national average for natural disaster exposure, ranking at the 73th percentile across all U.S. counties. Understanding the specific hazards behind Bradley County's ranking helps residents prioritize where to direct emergency planning efforts.

Hazard Breakdown

Earthquake risk is Bradley County's dominant natural hazard, ranked at the 92th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 88th percentile nationally. Additional tracked hazards include flood (69th percentile), hurricane (56th percentile), wildfire (47th percentile).

Preparedness Context

At the 92th percentile nationally for earthquake risk, Bradley County is in a zone where a post-earthquake communications plan matters almost as much as pre-earthquake structural preparation — phone networks are typically congested for hours after a significant event. The county's tornado risk at the 88th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. For Bradley County households, the three highest-impact earthquake preparedness actions are: (1) anchor heavy furniture and water heaters, (2) store three days of water at one gallon per person per day, and (3) identify a family reunification plan for the post-quake communication blackout period.

Regional Context

A composite score 21.0 points above the Tennessee state average puts Bradley County in a higher-risk category than most counties in the state.
