Risk Overview

About Natural Disaster Risk in Kodiak Island Borough, Alaska

Kodiak faces moderate U.S. disaster risk levels

With a composite risk score of 65.14, Kodiak Island Borough ranks as Relatively Low and moderately exceeds Alaska's state average of 35.22. This south-central island region experiences higher natural hazard exposure than most of the nation, but less than Alaska's highest-risk areas.

Mid-range risk profile within Alaska

Kodiak Island Borough ranks in Alaska's middle tier—safer than interior and peninsula powerhouses Fairbanks (88.52) and Kenai Peninsula (93.03), but riskier than Southeast Alaska communities. The 65.14 score reflects the island's geographic and seismic exposure.

Riskier than Southeast, safer than Kenai Peninsula

Kodiak (65.14) sits comfortably between Southeast Alaska's safe counties (1.69–14.31) and the high-risk interior and peninsula (88–93). The island's position and geology create moderate hazard exposure.

Earthquakes dominate; wildfires secondary concern

Earthquake risk peaks at 94.72, making seismic activity a dominant threat on Kodiak Island. Wildfire risk (23.22) poses a secondary concern, while flood (4.42) and tornado risks (0.48) remain minimal.

Earthquake insurance essential; wildfire awareness helpful

Earthquake coverage is non-negotiable given the 94.72 risk score—add it to your homeowners policy today. Keep your property cleared of vegetation and ensure roof and siding materials are fire-resistant to mitigate wildfire risk.

Risk Advisory: Kodiak Island Borough

Risk Verdict

With a national percentile rank of 65th, Kodiak Island Borough faces below-average hazard exposure relative to U.S. counties as a whole. Above-average risk does not mean imminent danger; it signals that informed, hazard-specific preparedness has high value here.

Hazard Breakdown

Earthquake risk is Kodiak Island Borough's dominant natural hazard, ranked at the 95th percentile nationally under FEMA's National Risk Index. Wildfire ranks second at the 23th percentile nationally. Additional tracked hazards include flood (4th percentile), tornado (0th percentile).

Preparedness Context

At the 95th percentile nationally for earthquake exposure, Kodiak Island Borough households benefit from practicing Drop, Cover, and Hold On — the protocol that minimizes injury during shaking. Getting under a sturdy table or desk and holding on until shaking stops is the key action. Wildfire, at the 23th percentile nationally in Kodiak Island Borough, adds a weather-dependent hazard layer to what is otherwise a seismic-dominated risk profile. Building age matters for earthquake risk in Kodiak Island Borough: structures built before local seismic code adoption are statistically more vulnerable. Contacting the local building department about retrofit programs can reveal whether your structure qualifies for mitigation assistance.

Regional Context

At 29.9 points above the Alaska state average, Kodiak Island Borough carries meaningfully higher natural disaster exposure than a typical Alaska county.

Yes, Kodiak Island Borough's earthquake risk is at the 95th percentile nationally. This places it in the top quartile for this hazard type. For flooding specifically, Kodiak Island Borough is at the 4th percentile.
How is natural disaster risk measured?
FEMA's National Risk Index (NRI) calculates risk scores for 18 natural hazard types across all U.S. counties and census tracts. The composite score combines Expected Annual Loss (estimated dollar losses from each hazard), Social Vulnerability (demographic factors affecting disaster impact), and Community Resilience (ability to recover). Percentile scores rank each county against all 3,144 U.S. counties, and risk ratings range from Very Low to Very High.
Why is Kodiak Island Borough higher risk than average?
Kodiak Island Borough's composite risk score of 65th percentile is above the Alaska state average of 35th percentile. This elevated risk is driven by earthquake exposure (95th percentile). Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
