Risk Overview

About Natural Disaster Risk in Clark County, Missouri

Clark County's minimal risk

Clark County scores just 21.82—Missouri's lowest recorded composite risk—placing it far below the state average of 50.56 with a Very Low national rating. The county represents one of America's safest jurisdictions for natural disaster exposure.

Missouri's safest county

Clark County holds the lowest composite risk score in Missouri at 21.82, significantly outpacing every other county statewide. Residents enjoy exceptional protection from major natural hazards.

Exceptional low-risk standing

Clark County's 21.82 score stands below even Cedar County (26.05) and Chariton County (29.42), creating a notably safe pocket in central Missouri. Nearby Cass County (74.90) and Christian County (66.48) face three times the hazard exposure.

Tornado presents primary concern

Tornadoes represent Clark County's highest risk at 25.60—still well below most counties—while wildfire (47.36) and flooding (30.50) remain minimal threats. The county's 21.82 composite score reflects balanced, low exposure across all hazard types.

Basic insurance provides security

Standard homeowners insurance with standard wind coverage adequately protects properties in Clark County's low-risk environment. A basic emergency kit and spring weather awareness complete preparedness; specialized hazard policies are unnecessary for typical properties.

Risk Advisory: Clark County

Risk Verdict

At the 22th percentile nationally, Clark County experiences relatively limited natural hazard pressure compared to most of the country. A 22th percentile score positions Clark County among the nation's lower-risk counties, a genuinely favorable outcome — one that simple, low-cost preparedness habits can reinforce further.

Hazard Breakdown

Wildfire risk is Clark County's dominant natural hazard, ranked at the 47th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 33th percentile nationally. Additional tracked hazards include flood (31th percentile), tornado (26th percentile), hurricane (14th percentile).

Preparedness Context

Clark County's dominant hazard is wildfire, ranked at the 47th percentile nationally. Maintaining at least 30 feet of lean, clean vegetation around structures in Clark County and keeping gutters clear of debris significantly reduces ignition risk from wind-driven embers. A secondary earthquake exposure at the 33th percentile nationally means Clark County residents face hazards from two distinct natural peril categories during different seasons. Clark County's households benefit from reviewing homeowners insurance before fire season, specifically whether the policy covers replacement cost rather than actual cash value, and whether it includes additional living expenses if displacement is required.

Regional Context

A composite score 28.7 points below the Missouri state average puts Clark County in a better-than-typical position relative to neighboring counties.
