Risk Overview

About Natural Disaster Risk in Tazewell County, Illinois

Tazewell faces elevated national risk

With a composite risk score of 84.19, Tazewell County ranks among the higher-risk counties nationally for natural disasters. This "Relatively Moderate" rating reflects substantial exposure across multiple hazard types, particularly tornadoes and flooding.

Illinois's highest-risk county surveyed

Tazewell's 84.19 score is the highest among the eight Illinois counties evaluated here, and substantially exceeds the state average of 54.46. The county faces notably elevated risk across nearly every natural disaster category.

Significantly riskier than surrounding counties

Tazewell (84.19) far exceeds the risk profiles of neighboring counties like Stephenson (73.92) and Vermilion (78.82) to the north and east. Its high earthquake (79.71) and tornado (90.49) scores make it the riskiest county in this immediate region.

Tornadoes pose the greatest threat

Tornado risk reaches 90.49 in Tazewell—among the highest in the nation—and flood risk stands at 84.35, both commanding immediate attention. Earthquake risk (79.71) also exceeds many peers, adding a seismic dimension to your county's hazard profile.

Invest in comprehensive protection now

Flood insurance is essential given your 84.35 flood risk; standard policies leave you vulnerable to water damage. A reinforced safe room or storm shelter is a critical upgrade for tornado protection, and ensure your policy explicitly covers wind, hail, and earthquake damage.

Risk Verdict

With a composite score at the 84th percentile, Tazewell County sits above the national median for natural hazard exposure. Proactive preparedness — not reactive response — is key to managing life in one of the country's higher-risk counties; Tazewell County residents should plan accordingly.

Hazard Breakdown

Tornado risk is Tazewell County's dominant natural hazard, ranked at the 90th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 84th percentile nationally. Additional tracked hazards include earthquake (80th percentile), hurricane (28th percentile), wildfire (8th percentile).

Preparedness Context

At the 90th percentile nationally for tornado risk, Tazewell County households benefit most from a reliable alert system — a NOAA weather radio that activates during overnight hours when residents may not be checking smartphone alerts. Alongside tornado exposure, flood at the 84th percentile nationally means Tazewell County households face multi-hazard severe-weather seasons that benefit from a single integrated emergency plan covering both threats. For Tazewell County households, a pre-decided family shelter plan — who goes where, how children are retrieved from school during a warning, and a neighborhood meet-up point if phones fail — provides real protection that no supply kit alone can replicate.

Regional Context

At 29.7 points above the Illinois state average, Tazewell County carries meaningfully higher natural disaster exposure than a typical Illinois county.
