Risk Overview
Overall natural disaster risk in Marshall County is very low, with a National Risk Index score of 21.4 out of 100 — placing it in the 21st 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.
Most of Marshall County's expected losses come from wildfire (uncontrolled fires that spread across wildland and into communities) at Low risk — $477K in expected annual loss and about 0.00 events per year; ice storm (freezing rain that coats surfaces in heavy, damaging ice) at Medium risk — $242K in expected annual loss and about 0.96 events per year; and strong wind (damaging straight-line winds outside of tornadoes and hurricanes) at Medium risk — $932K in expected annual loss and about 5.04 events per year. Across all hazards, FEMA estimates $8M in expected annual loss for a population of 10K.
Beyond physical exposure, Marshall County has a low social vulnerability rating (how susceptible the population is to harm) and a very high community resilience rating (its capacity to prepare for and recover from disasters). A less vulnerable population paired with strong resilience helps the community absorb and recover from events.
The county's disaster history tells the same story: Marshall County has received 18 federal disaster declarations since 1973, including 13 for severe storm events and 2 for biological events. The most recent was Severe Storms and Straight Line Winds (severe storm), declared in February 2022.
Among 105 Kansas counties, Marshall County ranks #51 for overall natural disaster risk.
