Preparedness Context
Overton County ranks at the 54th percentile nationally for earthquake risk.

Alongside earthquake exposure, Overton County's tornado risk at the 45th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. For earthquake preparedness, Overton County's county emergency management office often maintains a list of community water supply points, Red Cross shelter locations, and post-quake assistance programs — useful resources to identify before an event occurs.
Regional Context
A composite score 30.2 points below the Tennessee state average puts Overton County in a better-than-typical position relative to neighboring counties.
