Risk Overview

About Natural Disaster Risk in Scott County, Illinois

Scott ranks as one of safest

Scott County scores just 2.77 on the composite risk scale, earning a Very Low rating and placing it among the safest counties in Illinois. This score is approximately 95% below the state average of 54.46, indicating exceptionally minimal natural disaster exposure.

Illinois's lowest-risk county

Scott County is effectively the lowest-risk county in Illinois, with its 2.77 composite score surpassing virtually every other county in the state. The county experiences minimal exposure to all major disaster types, from tornadoes to earthquakes to flooding.

Safest in the tri-county area

Scott County's 2.77 score makes it safer than even its very-low-risk neighbors Stark County (7.25) and Schuyler County (11.36). The county's protection extends across all hazard types, reflecting stable geology, predictable weather patterns, and low riverine flood exposure.

Risks remain essentially negligible

Scott County's highest risk remains tornado exposure at 15.24, which is far below state norms and represents a minor threat in practical terms. All other hazards—flood, earthquake, hurricane, and wildfire—score below 10, making natural disaster an extraordinarily rare concern.

Standard coverage meets all needs

Scott County homeowners need only standard homeowners insurance and basic storm preparedness—flood insurance is optional unless in a mapped flood zone. The county's exceptional safety profile allows residents to focus insurance budgets on other priorities with confidence.

Risk Verdict

Scott County's natural disaster risk is among the lowest in the country, with a composite score at the 3th percentile nationally. The 3th percentile national ranking is one lens; Scott County residents also benefit from reviewing which specific hazard types drive the county's composite score and preparing accordingly.

Hazard Breakdown

Earthquake risk is Scott County's dominant natural hazard, ranked at the 29th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 15th percentile nationally. Additional tracked hazards include hurricane (9th percentile), flood (5th percentile), wildfire (0th percentile).

Preparedness Context

Earthquake risk is Scott County's leading natural hazard, ranked at the 29th percentile nationally. Securing tall furniture, water heaters, and bookcases to walls with anti-tip hardware is among the simplest and most effective life-safety measures households can take. Tornado at the 15th percentile nationally is a separate hazard dimension for Scott County that requires different protective strategies from earthquake preparedness. Scott County residents should locate the main gas shutoff valve and keep an appropriate wrench nearby — gas leaks cause a significant share of earthquake-related injuries and fires, and the shutoff step is safe to take immediately after shaking stops.

Regional Context

The Illinois county average exceeds Scott County's score by 51.7 composite points — placing this county in the lower-risk tier relative to its in-state peers.
