Among Kansas's riskier counties

Osage County ranks in the upper tier of Kansas counties for natural disaster risk, surpassing the state average on multiple hazard fronts. Its location in eastern Kansas contributes to heightened tornado and wildfire vulnerability statewide.

Elevated risk compared to Lyon and Morris

Osage County's 35.43 score exceeds neighboring Lyon and Morris Counties, reflecting higher tornado and wildfire exposure in this east-central region. The county faces notably elevated risk relative to its immediate western neighbors.

Wildfire and tornado lead hazards

Wildfire risk (74.94) and tornado risk (57.03) dominate Osage County's natural disaster profile, both significantly above state averages. Flood risk (30.22) and earthquake risk (27.16) add secondary vulnerabilities, though wildfire preparedness should be the primary planning focus.

Risk Verdict

Osage County's natural disaster risk is among the lowest in the country, with a composite score at the 35th percentile nationally. Osage County's 35th percentile ranking is favorable, though every county carries at least one natural hazard worth knowing — reviewing the specific risks listed above helps households focus their preparedness where it matters most.

Hazard Breakdown

Wildfire risk is Osage County's dominant natural hazard, ranked at the 75th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 57th percentile nationally. Additional tracked hazards include flood (30th percentile), earthquake (27th percentile), hurricane (0th percentile).

Preparedness Context

Wildfire is Osage County's top-ranked natural hazard at the 75th percentile nationally. Osage County residents should assess whether their property lies within or adjacent to a Wildland-Urban Interface (WUI) zone, where ember transport and rapid spread pose the highest risk. Alongside wildfire, tornado at the 57th percentile nationally means a multi-season preparedness mindset — fire season and flood or storm season often require different household plans. For Osage County households, a practiced evacuation plan — with a primary and backup route designated before a fire occurs — provides more protection than any structural improvement when a wildfire approaches fast-moving terrain.

Regional Context

Osage County's composite risk score sits 5.5 points above the Kansas county average, placing it among the more hazard-exposed counties in the state.
