Located in the interior eastern United States in Saline County, Harrisburg is a city of approximately 11,256 residents. The humid continental climate that characterizes this part of Illinois — marked by bitterly cold winters and hot, humid summers — directly influences the types and severity of natural hazards present, making Harrisburg a community where hazard awareness has real practical value.

FEMA rates Harrisburg's composite natural disaster risk at 6.5 out of 10 — high risk. Seismic activity is the dominant hazard, with the community situated in or near an active tectonic zone capable of producing damaging ground shaking. Residents should also account for wind and heat risk in their preparedness planning.

Relative to other U.S. communities, Harrisburg's natural disaster risk is above the U.S. national average of 4.5/10, slightly above the 5.8/10 state average. The hazard distribution here is led by earthquake and wind, as measured by FEMA across Saline County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

Harrisburg's high risk designation reflects meaningful exposure to natural hazards. Residents should verify that their insurance covers the area's primary risks, prepare a family emergency plan, and stay informed about seasonal hazard peaks through local weather and emergency management services.
