Natural Disaster Risk in Iliamna

Natural Hazard Profile: Iliamna, Alaska

Located in Alaska, the northernmost U.S. state in Lake and Peninsula County, Iliamna is a small unincorporated community. 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 Iliamna a community where hazard awareness has real practical value.

FEMA rates Iliamna's composite natural disaster risk at 4.4 out of 10 — moderate risk. Tsunami risk is the primary coastal hazard, driven by the area's proximity to seismically active offshore zones capable of generating ocean waves that inundate low-lying coastlines. Residents should also account for volcano and avalanche risk in their preparedness planning.

Relative to other U.S. communities, Iliamna's natural disaster risk is near the U.S. national average of 4.5/10, near the 4.6/10 state average. The hazard distribution here is led by tsunami and volcano, as measured by FEMA across Lake and Peninsula County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a moderate risk rating, Iliamna 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 tsunami is recommended.
