Risk Overview
About Natural Disaster Risk in Logan County, Illinois
Logan County sits near average risk
With a composite risk score of 58.1 and a relatively low rating, Logan County sits slightly above the national average. This reflects moderate tornado and earthquake exposure balanced by low wildfire risk.
Slightly above Illinois' state average
Logan County's score of 58.1 exceeds Illinois' state average of 54.5, but only modestly. The county ranks in the middle of Illinois' risk distribution, making it relatively resilient compared to state peers.
Risk profile typical for the region
Logan County's score of 58.1 closely parallels Lee County (54.4) and sits well below Livingston County (71.8). The county maintains a moderate risk position consistent with its neighboring counties.
Tornadoes and earthquakes matter most
Logan County's tornado risk of 69.8 and earthquake risk of 76.8 represent its primary hazard exposures. While both pose meaningful threats, the county's low flood and wildfire risks reduce overall vulnerability.
Cover tornado and earthquake damage
Logan County homeowners should verify that wind and hail coverage in their homeowners policy is adequate for severe weather and tornadoes. Consider earthquake insurance as a separate policy, particularly for older structures that may be more vulnerable to seismic damage.

Hazard Breakdown
Earthquake risk is Logan County's dominant natural hazard, ranked at the 77th percentile nationally under FEMA's National Risk Index. Tornado ranks second at the 70th percentile nationally. Additional tracked hazards include flood (54th percentile), hurricane (25th percentile), wildfire (1th percentile).
Preparedness Context
At the 77th percentile nationally for earthquake risk, Logan County is in a zone where a post-earthquake communications plan matters almost as much as pre-earthquake structural preparation — phone networks are typically congested for hours after a significant event. The county's tornado risk at the 70th percentile nationally is a seasonal consideration alongside the year-round earthquake threat, requiring awareness of both hazard types. For Logan County households, the three highest-impact earthquake preparedness actions are: (1) anchor heavy furniture and water heaters, (2) store three days of water at one gallon per person per day, and (3) identify a family reunification plan for the post-quake communication blackout period.
Regional Context
Logan County's composite risk score is within 3.6 points of the Illinois county average — a close alignment that reflects a broadly representative hazard environment for this part of the state.
