Risk Overview

About Natural Disaster Risk in Coles County, Illinois

Coles County faces moderate disaster risk

Coles County's composite risk score of 70.36 surpasses the national average, signaling above-average exposure to natural disasters. The Relatively Low rating reflects a mixed hazard profile with some significant exposures.

Above-average risk for Illinois

At 70.36, Coles County scores substantially higher than Illinois's state average of 54.46, placing it in the upper half of state counties by risk level. Residents face greater hazard exposure than most other Illinoisans.

Riskier than most surrounding counties

Coles County (70.36) ranks riskier than Cass County (38.65), Clark County (27.32), and Christian County (54.04), but safer than Champaign County (90.46). It represents one of the higher-risk areas in east-central Illinois.

Floods and tornadoes pose primary threats

Coles County's flood risk (74.49) and tornado risk (72.11) substantially exceed state averages and dominate the county's composite score. These two weather-related hazards represent the most significant disaster risks for residents.

Prioritize comprehensive weather coverage

Coles County residents should obtain separate flood insurance and ensure strong tornado coverage, as standard homeowners policies exclude flood damage. Developing a family emergency plan is equally essential given the county's significant severe weather exposure.

Risk Verdict

At the 70th percentile nationally, Coles County experiences a manageable level of natural hazard risk that falls below the U.S. median. Coles County's risk profile calls for targeted preparedness, focusing on the hazard categories that dominate the county's score.

Hazard Breakdown

Earthquake risk is Coles County's dominant natural hazard, ranked at the 87th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 74th percentile nationally. Additional tracked hazards include tornado (72th percentile), hurricane (39th percentile), wildfire (10th percentile).

Preparedness Context

Coles County's primary hazard, earthquake, ranks at the 87th percentile nationally. Unreinforced masonry structures carry the highest injury risk during seismic events; residents in older buildings should check with their municipality about available seismic retrofit programs. The county's flood risk at the 74th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. After a major earthquake, Coles County residents should expect water service disruption for 24 to 72 or more hours. Storing a minimum of one gallon per person per day for three days — before any event — is the most direct preparedness action households can take.

Regional Context

Coles County falls 15.9 points above Illinois's typical county risk level, which means the hazard environment here is notably more demanding than the state baseline.

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 Coles County higher risk than average?
Coles County's composite risk score of 70th percentile is above the Illinois state average of 55th percentile. This elevated risk is driven by earthquake exposure (87th percentile), along with flooding and tornado risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
