Risk Overview

About Natural Disaster Risk in Calhoun County, Mississippi

Calhoun County: well below national average

Calhoun County scores 27.67 on the composite risk scale, placing it in the very low risk category and significantly below the national average. This favorable profile reflects relatively modest exposure to most major natural hazards.

Among Mississippi's safest counties

Calhoun County's 27.67 score sits well below Mississippi's 50.94 state average, ranking it among the state's lower-risk areas. This below-average standing positions Calhoun as a safer choice compared to most Mississippi counties.

Safer than most northeast Mississippi peers

Calhoun County's 27.67 score outperforms neighboring Yalobusha, Grenada, and Chickasaw counties, establishing it as a regional safety standout. Its central-east location provides distance from both Gulf hurricane zones and the Delta flood belt.

Tornado and earthquake are modest concerns

Tornado risk reaches 49.36 and earthquake risk 76.78, representing Calhoun County's highest hazards, though both remain manageable. Flood risk is notably low at 25.35, reflecting the county's slightly elevated terrain relative to surrounding areas.

Standard coverage is likely sufficient

A standard homeowners policy with tornado and wind coverage should address Calhoun County's primary risks. Flood insurance is optional for most residents outside designated flood zones given the county's modest 25.35 flood risk score.

Risk Verdict

Natural disaster exposure in Calhoun County is lower than roughly three-quarters of U.S. counties, with a composite score at the 28th percentile. Even at the 28th percentile, Calhoun County's composite score reflects real hazard exposure categories — knowing which ones apply locally enables targeted, efficient household preparedness.

Hazard Breakdown

Earthquake risk is Calhoun County's dominant natural hazard, ranked at the 77th percentile nationally under FEMA's National Risk Index. Hurricane ranks second at the 64th percentile nationally. Additional tracked hazards include tornado (49th percentile), wildfire (26th percentile), flood (25th percentile).

Preparedness Context

At the 77th percentile nationally for earthquake risk, Calhoun County is in a zone where a post-earthquake communications plan matters almost as much as pre-earthquake structural preparation — phone networks are typically congested for hours after a significant event. Hurricane at the 64th percentile nationally is a separate hazard dimension for Calhoun County that requires different protective strategies from earthquake preparedness. For Calhoun County households, the three highest-impact earthquake preparedness actions are: (1) anchor heavy furniture and water heaters, (2) store three days of water at one gallon per person per day, and (3) identify a family reunification plan for the post-quake communication blackout period.

Regional Context

Calhoun County is 23.3 composite risk points below the Mississippi state mean, meaning most other Mississippi counties face higher natural hazard exposure.
