Risk Overview

About Natural Disaster Risk in Vermilion County, Illinois

Vermilion faces above-average national risk

With a composite risk score of 78.82, Vermilion County ranks in the upper tier of natural disaster risk nationally. This "Relatively Low" rating reflects substantial exposure to tornadoes, floods, and earthquakes across its central Illinois location.

Well above Illinois state average

Vermilion's 78.82 score significantly exceeds Illinois's 54.46 state average, placing it among the state's higher-risk counties. The county faces elevated hazards across multiple categories, not concentrated in a single disaster type.

Comparable to Tazewell, exceeds Warren

Vermilion (78.82) approaches the risk level of neighboring Tazewell County (84.19) to the northwest while far exceeding Warren County (15.49) to the west. Its balanced multi-hazard profile sets it apart from counties dominated by a single threat.

Tornadoes and floods lead threats

Tornado risk (79.71) and flood risk (76.46) are your county's primary hazards, each substantially exceeding national averages. Earthquake risk (85.24) rounds out a notably complex hazard landscape for a central Illinois county.

Prepare for multiple disaster types

Flood insurance is non-negotiable given your 76.46 flood risk score; it's not included in standard homeowners policies. Invest in a safe room or shelter for tornado protection, and ensure your policy covers wind, hail, and earthquake damage—you face meaningful risk across all three.

Risk Advisory: Vermilion County

Risk Verdict

At the 79th percentile nationally, Vermilion County experiences a manageable level of natural hazard risk that falls below the U.S. median. High composite risk signals that multiple hazard types are elevated simultaneously; planning for more than one scenario is important in Vermilion County.

Hazard Breakdown

Earthquake risk is Vermilion County's dominant natural hazard, ranked at the 85th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 80th percentile nationally. Additional tracked hazards include flood (76th percentile), hurricane (46th percentile), wildfire (23th percentile).

Preparedness Context

Vermilion County's primary hazard, earthquake, ranks at the 85th 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. Tornado at the 80th percentile nationally is a separate hazard dimension for Vermilion County that requires different protective strategies from earthquake preparedness. After a major earthquake, Vermilion 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

Vermilion County falls 24.4 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 Vermilion County higher risk than average?
Vermilion County's composite risk score of 79th percentile is above the Illinois state average of 55th percentile. This elevated risk is driven by earthquake exposure (85th percentile), along with tornado and flooding risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
