Natural Disaster Risk in Wasilla

Natural Hazard Profile: Wasilla, Alaska

Located in Alaska, the northernmost U.S. state in Matanuska-Susitna County, Wasilla is a city of approximately 44,647 residents. The subarctic climate that characterizes this part of Alaska — marked by subarctic conditions with extreme cold winters and brief summers — directly influences the types and severity of natural hazards present, making Wasilla a community where hazard awareness has real practical value.

FEMA rates Wasilla's composite natural disaster risk at 5.8 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 earthquake and tsunami risk in their preparedness planning.

Relative to other U.S. communities, Wasilla's natural disaster risk is above the U.S. national average of 4.5/10, slightly above the 4.6/10 state average. The hazard distribution here is led by avalanche and earthquake, as measured by FEMA across Matanuska-Susitna County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Wasilla 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.
