Risk Overview

Overall natural disaster risk in Comanche County is very low, with a National Risk Index score of 20.2 out of 100 — placing it in the 20th national percentile and among the lowest-risk counties in the country. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.

The county's risk is driven primarily by wildfire (uncontrolled fires that spread across wildland and into communities) at Medium risk — $3M in expected annual loss and about 0.02 events per year; drought (extended dry periods that stress water supplies and agriculture) at Medium risk — $1M in expected annual loss and about 72.88 events per year; and hail (ice stones from severe thunderstorms that damage property and crops) at Low risk — $305K in expected annual loss and about 9.85 events per year. Across all hazards, FEMA estimates $6M in expected annual loss for a population of 2K.

Beyond physical exposure, Comanche County has a high social vulnerability rating (how susceptible the population is to harm) and a medium community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.

The federal record bears this out: Comanche County has received 22 federal disaster declarations since 1973, including 14 for severe storm events and 2 for biological events. The most recent was Severe Storms, Straight-Line Winds, and Flooding (severe storm), declared in December 2025.

Among 105 Kansas counties, Comanche County ranks #55 for overall natural disaster risk.
