Risk Overview

About Natural Disaster Risk in Iron County, Missouri

Iron County above-average national risk

Iron County's composite risk score of 69.50 exceeds the national average, earning a Relatively Low rating despite elevated exposure. Your county faces substantially more natural disaster threats than the typical American county.

Upper tier of Missouri risk

At 69.50, Iron County scores 137% of Missouri's statewide average of 50.56, placing it firmly in the state's higher-risk category. Your county ranks among Missouri's more hazard-exposed communities.

Riskier than most central neighbors

Iron County's 69.50 score exceeds Hickory County (23.47), Harrison County (29.33), and Henry County (52.77), but remains somewhat below Howell County (77.77). Your county faces elevated multi-hazard exposure compared to most regional peers.

Earthquake and flood dominate

Earthquake risk scores 78.09 and flood risk reaches 64.47—Iron County's two primary hazard concerns requiring serious preparation. Tornado (58.37) and wildfire (50.83) risks are also notable secondary threats.

Prioritize earthquake and flood coverage

Iron County homeowners should obtain separate earthquake and flood insurance policies, as standard homeowner's insurance excludes both. Review your coverage annually with a local agent and secure heavy furniture, creating a seismic safety plan for your household.

Risk Advisory: Iron County

Risk Verdict

With a national percentile rank of 69th, Iron County faces below-average hazard exposure relative to U.S. counties as a whole. Above-average risk does not mean imminent danger; it signals that informed, hazard-specific preparedness has high value here.

Hazard Breakdown

Earthquake risk is Iron County's dominant natural hazard, ranked at the 78th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 64th percentile nationally. Additional tracked hazards include tornado (58th percentile), wildfire (51th percentile), hurricane (29th percentile).

Preparedness Context

At the 78th percentile nationally for earthquake exposure, Iron County households benefit from practicing Drop, Cover, and Hold On — the protocol that minimizes injury during shaking. Getting under a sturdy table or desk and holding on until shaking stops is the key action. Flood at the 64th percentile nationally is a separate hazard dimension for Iron County that requires different protective strategies from earthquake preparedness. Building age matters for earthquake risk in Iron County: structures built before local seismic code adoption are statistically more vulnerable. Contacting the local building department about retrofit programs can reveal whether your structure qualifies for mitigation assistance.

Regional Context

At 18.9 points above the Missouri state average, Iron County carries meaningfully higher natural disaster exposure than a typical Missouri county.

Frequently Asked Questions

What is the natural disaster risk in Iron County, MO?
Iron County has a FEMA National Risk Index rating of Relatively Low, placing it in the 69th percentile nationally out of 3,144 counties. This composite score reflects the county's overall exposure to natural hazards including floods, wildfires, tornadoes, earthquakes, and hurricanes, weighted by expected annual loss and social vulnerability.
What types of natural hazards affect Iron County?
Iron County is evaluated for five major natural hazard types: earthquake (78th percentile), flooding (64th percentile), tornado (58th percentile), wildfire (51th percentile), hurricane (29th percentile). The highest-risk hazard is earthquake at the 78th percentile nationally. These scores are derived from FEMA's National Risk Index, which analyzes expected annual loss, social vulnerability, and community resilience for each hazard type.
How does Iron County risk compare to the Missouri average?
Iron County's composite risk percentile is 69th, compared to the Missouri state average of 51th percentile. The state's overall risk rating is Relatively Low. This means Iron County faces higher natural disaster risk than the typical county in Missouri.
Is Iron County at risk for earthquake?
Yes, Iron County's earthquake risk is at the 78th percentile nationally. This places it in the top quartile for this hazard type. For flooding specifically, Iron County is at the 64th percentile.
How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Iron County higher risk than average?
Iron County's composite risk score of 69th percentile is above the Missouri state average of 51th percentile. This elevated risk is driven by earthquake exposure (78th percentile), along with flooding and tornado and wildfire risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
