About Natural Disaster Risk in Morgan County, Illinois

Morgan County's disaster risk above national norm

Morgan County's composite risk score of 71.12 exceeds the national average, reflecting above-typical exposure to natural hazards. The relatively low risk rating indicates moderate concern, though residents face more disaster threats than most U.S. counties.

Among Illinois's highest-risk counties

Morgan County's composite score of 71.12 substantially exceeds Illinois's 54.46 average, placing it firmly in the higher-risk tier statewide. Only a handful of Illinois counties face comparable or greater natural disaster exposure.

Riskiest in central Illinois cluster

Morgan County (71.12) carries higher risk than Montgomery County (65.39), Ogle County (71.09), and significantly outpaces Monroe County (41.86) and Mercer County (8.78). Residents face the most hazard exposure among nearby counties.

Earthquakes and floods top the threat list

Earthquake risk (81.68) and flood risk (61.23) represent Morgan County's primary hazards, both well above state averages. Tornado risk (49.59) adds to the concern, while wildfire risk remains minimal at 1.84.

Comprehensive protection is crucial

Morgan County homeowners must prioritize earthquake insurance and flood insurance alongside standard homeowners coverage. Given the elevated earthquake and flood risks, reviewing and updating policies annually is essential.

Risk Advisory: Morgan County

Risk Verdict

With a national percentile rank of 71th, Morgan County faces below-average hazard exposure relative to U.S. counties as a whole. Above-average risk does not mean imminent danger; it signals that informed, hazard-specific preparedness has high value here.

Hazard Breakdown

Earthquake risk is Morgan County's dominant natural hazard, ranked at the 82th percentile nationally under FEMA's National Risk Index. Flood ranks second at the 61th percentile nationally. Additional tracked hazards include tornado (50th percentile), hurricane (22th percentile), wildfire (2th percentile).

Preparedness Context

At the 82th percentile nationally for earthquake exposure, Morgan County households benefit from practicing Drop, Cover, and Hold On — the protocol that minimizes injury during shaking. Getting under a sturdy table or desk and holding on until shaking stops is the key action. The county's flood risk at the 61th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. Building age matters for earthquake risk in Morgan County: structures built before local seismic code adoption are statistically more vulnerable. Contacting the local building department about retrofit programs can reveal whether your structure qualifies for mitigation assistance.

Regional Context

At 16.7 points above the Illinois state average, Morgan County carries meaningfully higher natural disaster exposure than a typical Illinois county.

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 Morgan County higher risk than average?
Morgan County's composite risk score of 71th percentile is above the Illinois state average of 55th percentile.
