Natural Disaster Risk in Mark

Natural Hazard Profile: Mark, Illinois

Located in the interior eastern United States in Putnam County, Mark is a small community of about 545. 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 Mark a community where hazard awareness has real practical value.

Mark's overall natural disaster risk is rated 4.0/10 (Moderate) by FEMA's National Risk Index. Prolonged drought is the primary hazard risk, shaped by low annual rainfall, high evaporation rates, and increasing temperature trends that deepen and lengthen dry periods. Secondary hazards include landslide and tsunami.

Relative to other U.S. communities, Mark's natural disaster risk is near the U.S. national average of 4.5/10, considerably below the 5.8/10 state average. The hazard distribution here is led by drought and landslide, as measured by FEMA across Putnam County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Mark residents are well-served by maintaining standard preparedness practices — an emergency supply kit, awareness of local hazard seasonality, and insurance that covers the top local risks. Periodic review of coverage for drought is recommended.
