Risk Overview

About Natural Disaster Risk in Carter County, Missouri

Carter County's moderate risk profile

Carter County scores 53.94—slightly above Missouri's state average of 50.56—reflecting Relatively Low overall risk nationally. However, one hazard stands out dramatically: earthquake risk of 82.19 significantly exceeds typical American county levels.

Middle-of-the-pack Missouri risk

Carter County ranks near the state median for overall disaster risk, though its earthquake exposure is among the highest in Missouri. Residents face above-average seismic hazard compared to neighboring counties.

Earthquake risk sets it apart

Carter County's 82.19 earthquake score far exceeds nearby Carroll County (36.48) and Cedar County (43.67), reflecting proximity to the Ozark seismic zone. Flooding (60.59) and wildfire (47.46) present moderate secondary risks across the region.

Earthquakes and flooding dominate

Earthquakes rank as Carter County's top hazard at 82.19, while flooding (60.59) presents a secondary threat that affects low-lying properties and riverfront areas. Though rare, seismic events can cause structural damage; floods damage foundations and basements regularly.

Earthquake insurance is critical

Standard homeowners policies exclude earthquake damage—you must purchase separate coverage, especially given Carter County's 82.19 score. Secure heavy furniture and appliances, and ensure flood insurance covers basement areas vulnerable to rising water.

Risk Verdict

Carter County sits below the national average for natural disaster exposure, ranking at the 54th percentile across all U.S. counties. Understanding the specific hazards behind Carter County's ranking helps residents prioritize where to direct emergency planning efforts.

Hazard Breakdown

Earthquake risk is Carter County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 61th percentile nationally. Additional tracked hazards include wildfire (47th percentile), tornado (40th percentile), hurricane (31th percentile).

Preparedness Context

At the 82th percentile nationally for earthquake risk, Carter 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. The county's flood risk at the 61th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. For Carter 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

Carter County's composite risk score is within 3.4 points of the Missouri county average — a close alignment that reflects a broadly representative hazard environment for this part of the state.

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 Carter County higher risk than average?
Carter County's composite risk score of 54th percentile is above the Missouri state average of 51th percentile. This elevated risk is driven by earthquake exposure (82th percentile), along with flooding risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
