Risk Overview

About Natural Disaster Risk in Howell County, Missouri

Howell County faces above-average risk

Howell County's composite risk score of 77.77 significantly exceeds the national average, though it maintains a Relatively Low overall rating. This means your county encounters considerably more natural disaster exposure than a typical American county.

Among Missouri's higher-risk counties

At 77.77, Howell County scores 154% of Missouri's average of 50.56, ranking it in the state's upper-risk tier. Your county faces substantially more multi-hazard exposure than most Missouri communities.

Significantly riskier than Iron County

Howell County's 77.77 score exceeds Iron County (69.50) and all central Missouri neighbors by substantial margins. Your county represents one of the state's most hazard-exposed communities, particularly for earthquake and flood risks.

Earthquake and flood threats severe

Earthquake risk scores 91.06 and flood risk reaches 79.61—both critical concerns placing Howell County among Missouri's most seismically and hydrologically vulnerable areas. Tornado risk (76.62) and wildfire risk (75.45) compound the exposure, making this a multi-hazard hotspot.

Comprehensive protection essential

Howell County residents must secure robust homeowner's insurance explicitly covering earthquake, flood, and windstorm damage—standard policies often exclude these. Work with a local agent to ensure full coverage and maintain emergency supplies, an evacuation plan, and secure household items against seismic activity.

Risk Advisory: Howell County

Risk Verdict

Howell County sits below the national average for natural disaster exposure, ranking at the 78th percentile across all U.S. counties. Howell County's elevated composite score reflects cumulative multi-hazard exposure; households should prepare for the county's two or three primary hazard types.

Hazard Breakdown

Earthquake risk is Howell County's dominant natural hazard, ranked at the 91th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 80th percentile nationally. Additional tracked hazards include tornado (77th percentile), wildfire (75th percentile), hurricane (42th percentile).

Preparedness Context

At the 91th percentile nationally for earthquake risk, Howell 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. Alongside earthquake exposure, Howell County's flood risk at the 80th percentile nationally reinforces the value of maintaining a household emergency supply cache usable for multiple hazard scenarios. For Howell 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

A composite score 27.2 points above the Missouri state average puts Howell County in a higher-risk category than most counties in 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 Howell County higher risk than average?
Howell County's composite risk score of 78th percentile is above the Missouri state average of 51th percentile. This elevated risk is driven by earthquake exposure (91th 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.
