Preparedness Context
Earthquake exposure at the 85th percentile nationally puts Humphreys County in a zone where utilities — gas, water, electrical — are the most common post-quake hazard. Knowing how to shut off the main gas valve is an important household skill to develop before an event occurs. Alongside earthquake exposure, Humphreys County's tornado risk at the 75th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. Humphreys County households benefit from keeping shoes and a flashlight near the bed — post-earthquake navigation through debris in the dark is a common cause of secondary injury. This low-cost step has outsized protective value.
Regional Context
Humphreys County's risk score is broadly comparable to the Tennessee county average, with a 4.2-point gap that places the county near the center of the state's hazard distribution.
