About Natural Disaster Risk in Nemaha County, Kansas

Nemaha County: low risk below state average

Nemaha County's composite risk score of 17.43 places it well below Kansas's state average of 29.89, earning a very low risk rating nationally. This county faces substantially less natural disaster exposure than most U.S. counties, though vigilance remains important for localized hazards.

Among Kansas's safest counties

Ranking near the bottom of Kansas counties for overall disaster risk, Nemaha County scores significantly lower than the state average across most hazard categories. Its very low composite score reflects relatively minimal exposure to major natural threats statewide.

Lower risk than eastern Kansas peers

Nemaha County's 17.43 score outperforms neighboring Doniphan and Marshall Counties in overall safety, though wildfire risk (82.82) does exceed regional norms. The county's tornado risk (58.30) mirrors typical northeast Kansas exposure patterns.

Wildfire emerges as primary hazard

Wildfire risk at 82.82 significantly outpaces other hazards in Nemaha County, reflecting grassland conditions and seasonal drought patterns common to the region. Tornado risk follows at 58.30, while flood risk (23.31) and earthquake risk (21.85) pose secondary concerns.

Secure wildfire and tornado coverage

Homeowners in Nemaha County should prioritize comprehensive wildfire insurance and wind damage coverage given the county's high wildfire exposure relative to other risks. Bundle these protections with standard homeowner's insurance and create a defensible space plan around your property.

Risk Verdict

Natural disaster exposure in Nemaha County is lower than roughly three-quarters of U.S. counties, with a composite score at the 17th percentile. The 17th percentile national ranking is one lens; Nemaha County residents also benefit from reviewing which specific hazard types drive the county's composite score and preparing accordingly.

Hazard Breakdown

Wildfire risk is Nemaha County's dominant natural hazard, ranked at the 83th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 58th percentile nationally. Additional tracked hazards include flood (23th percentile), earthquake (22th percentile), hurricane (0th percentile).

Preparedness Context

At the 83th percentile nationally for wildfire, Nemaha County residents should verify whether their insurance policy includes replacement cost coverage for structures and whether the insurer still writes new policies in this fire-risk zone. The county's tornado exposure at the 58th percentile nationally complements the wildfire risk — saturating rain after burn scarring often triggers secondary flood and debris flow events. Local USFS or Cal Fire (where applicable) fire risk maps and seasonal Red Flag Warning alerts from the National Weather Service are two free resources Nemaha County residents can use to stay ahead of rapidly changing wildfire conditions.

Regional Context

Nemaha County is 12.5 composite risk points below the Kansas state mean, meaning most other Kansas counties face higher natural hazard exposure.
