Natural Disaster Risk in Granville

Natural Hazard Profile: Granville, Pennsylvania

Located in the interior eastern United States in Mifflin County, Granville is a small unincorporated community. The humid continental climate that characterizes this part of Pennsylvania — marked by cold winters, warm summers, and four distinct seasons — directly influences the types and severity of natural hazards present, making Granville a community where hazard awareness has real practical value.

FEMA rates Granville's composite natural disaster risk at 5.6 out of 10 — moderate risk. Avalanche risk is the dominant natural hazard, with steep mountain terrain and heavy seasonal snowpack creating conditions for dangerous snow slides in and around the area. Residents should also account for hurricane and landslide risk in their preparedness planning.

Relative to other U.S. communities, Granville's natural disaster risk is above the U.S. national average of 4.5/10, near the 5.9/10 state average. The hazard distribution here is led by avalanche and hurricane, as measured by FEMA across Mifflin County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Granville 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 avalanche is recommended.
