Risk Overview

About Natural Disaster Risk in Marshall County, Kentucky

Marshall faces above-average disaster exposure

With a composite risk score of 61.93, Marshall County ranks as 'relatively low' but sits above the national average of 50.19. Earthquake risk (92.59) is exceptionally high—among the most significant in the state—making seismic preparedness essential.

Marshall's earthquake risk is statewide standout

Marshall's composite score of 61.93 exceeds Kentucky's state average of 44.21, driven largely by its extraordinary earthquake risk of 92.59. This seismic vulnerability is one of the highest in Kentucky and demands serious mitigation planning.

Marshall stands out for earthquake threat

While Marshall's composite score of 61.93 is moderate among neighbors, its earthquake risk of 92.59 dramatically exceeds nearby McCracken County's 97.55—both among the state's highest. Marshall's tornado exposure (60.78) is comparable to regional peers but far lower than its seismic risk.

Earthquakes pose the dominant threat here

Earthquake risk at 92.59 is Marshall's defining hazard and among Kentucky's highest, warranting retrofit investments and emergency preparedness that most counties never need. Tornado risk (60.78) and flooding (47.26) are secondary but still significant concerns for the region.

Retrofit now for earthquake resilience

With earthquake risk at 92.59, secure your home's foundation, brace water heaters, and bolt heavy furniture to walls—measures that pay dividends when seismic activity strikes. Standard homeowner's insurance doesn't cover earthquake damage; obtain a separate earthquake policy and ensure your policy limits align with replacement costs.

Risk Advisory: Marshall County

Risk Verdict

Natural hazard pressure in Marshall County is below the national midpoint, with a composite score at the 62th percentile. Proactive emergency planning and awareness of the specific hazards driving Marshall County's score can meaningfully reduce household risk.

Hazard Breakdown

Earthquake risk is Marshall County's dominant natural hazard, ranked at the 93th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 61th percentile nationally. Additional tracked hazards include flood (47th percentile), hurricane (42th percentile), wildfire (29th percentile).

Preparedness Context

Earthquake exposure at the 93th percentile nationally puts Marshall County in a zone where utilities — gas, water, electrical — are the most common post-quake hazard. Knowing how to shut off the main gas valve is an important household skill to develop before an event occurs. The county's tornado risk at the 61th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. Marshall County households benefit from keeping shoes and a flashlight near the bed — post-earthquake navigation through debris in the dark is a common cause of secondary injury. This low-cost step has outsized protective value.

Regional Context

Marshall County is 17.7 composite risk points above the Kentucky average, indicating that residents face greater natural hazard exposure than most of their in-state neighbors.

Frequently Asked Questions

What is the natural disaster risk in Marshall County, KY?
Marshall County has a FEMA National Risk Index rating of Relatively Low, placing it in the 62th 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 Marshall County?
Marshall County is evaluated for five major natural hazard types: earthquake (93th percentile), tornado (61th percentile), flooding (47th percentile), hurricane (42th percentile), wildfire (29th percentile). The highest-risk hazard is earthquake at the 93th 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 Marshall County risk compare to the Kentucky average?
Marshall County's composite risk percentile is 62th, compared to the Kentucky state average of 44th percentile. The state's overall risk rating is Relatively Low. This means Marshall County faces higher natural disaster risk than the typical county in Kentucky.
Is Marshall County at risk for earthquake?
Yes, Marshall County's earthquake risk is at the 93th percentile nationally. This places it in the top quartile for this hazard type. For flooding specifically, Marshall County is at the 47th 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 Marshall County higher risk than average?
Marshall County's composite risk score of 62th percentile is above the Kentucky state average of 44th percentile. This elevated risk is driven by earthquake exposure (93th percentile), along with tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
