Preparedness Context
Earthquake exposure at the 83th percentile nationally puts Spencer 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, Spencer County's tornado risk at the 56th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. Spencer 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.
