Risk Overview

About Natural Disaster Risk in Chariton County, Missouri

Chariton County's very low risk

Chariton County scores 29.42, placing it well below Missouri's state average of 50.56 with a Very Low national risk rating. The county's balanced hazard exposure means residents face below-average disaster threats compared to most Americans.

Among Missouri's safest

Chariton County ranks in the lowest tier of Missouri counties for natural disaster risk, sitting comfortably below the state median. Few Missouri residents enjoy comparable safety from major hazards.

Low-risk regional cluster

Chariton County (29.42) joins Carroll County (32.60) and Cedar County (26.05) in a relatively safe region, with all three scoring well below 50. This trio represents some of Missouri's most stable areas for disaster risk.

Tornado risk most significant

Tornadoes present the primary hazard with a 50.64 score, though this remains moderate by state standards. Wildfire (48.19) and flooding (44.15) pose secondary concerns, while earthquakes (42.05) and hurricanes (21.32) are minimal threats.

Standard insurance serves well

Chariton County's low-risk profile means comprehensive homeowners coverage with wind protection covers most disaster scenarios adequately. Seasonal tornado watches warrant a family emergency plan, but the county does not justify specialized hazard policies for typical properties.

Risk Verdict

Chariton County carries a low natural disaster risk burden, scoring at the 29th percentile under the FEMA National Risk Index.

Hazard Breakdown

Tornado risk is Chariton County's dominant natural hazard, ranked at the 51th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 48th percentile nationally. Additional tracked hazards include flood (44th percentile), earthquake (42th percentile), hurricane (21th percentile).

Preparedness Context

Chariton County's primary hazard, tornado, ranks at the 51th percentile nationally. In Chariton County, mobile homes and manufactured housing face significantly higher tornado risk than site-built structures; residents in these homes should identify the nearest permanent community shelter in advance. Alongside tornado exposure, wildfire at the 48th percentile nationally means Chariton County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. The highest-risk window for tornado fatalities is overnight, when Chariton County residents may be asleep. A NOAA weather radio with overnight alert capability is the single most impactful low-cost preparedness step available to Chariton County households.

Regional Context

Compared to the Missouri county average, Chariton County's composite score runs 21.1 points lower — a gap that reflects the county's relatively modest hazard profile within its state context.
