Alongside earthquake exposure, Allen County's tornado risk at the 69th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. Allen 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
