Risk Overview
About Natural Disaster Risk in Kenai Peninsula Borough, Alaska
Kenai Peninsula faces elevated U.S. disaster risk
With a composite score of 93.03, Kenai Peninsula Borough ranks as Relatively Moderate and far exceeds Alaska's state average of 35.22. This south-central region is among the nation's higher-risk counties, driven by seismic and wildfire hazards.
Alaska's highest-risk county overall
Kenai Peninsula Borough edges out Fairbanks North Star Borough (88.52) as Alaska's riskiest region. The peninsula's combination of wildfire exposure and earthquake activity creates the state's most severe natural disaster profile.
Dramatically riskier than Southeast, comparable to Fairbanks
Kenai Peninsula (93.03) vastly exceeds Southeast Alaska counties like Juneau (11.51) and Ketchikan (1.69), and nearly matches Fairbanks (88.52) in overall risk. This south-central location exposes residents to hazards largely absent in the Southeast.
Earthquakes and wildfires present extreme threats
Earthquake risk peaks at 98.70—nearly maximal—while wildfire risk reaches 97.07, making both near-certain hazards residents will face. Flood risk (43.77) poses a meaningful secondary threat during spring snowmelt and coastal storm surge.
Earthquake and wildfire insurance are absolutely essential
Do not skip earthquake and wildfire insurance—both hazards are nearly certain in this region and standard homeowners policies exclude them. Clear brush within 100+ feet of your home, use fire-resistant roofing, and ensure your foundation is bolted to withstand seismic activity.

Preparedness Context
At the 99th percentile nationally for earthquake exposure, Kenai Peninsula 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. Kenai Peninsula Borough's secondary hazard, wildfire at the 97th percentile nationally, requires different alert monitoring and response than earthquake — households benefit from understanding the distinct early-warning systems for each. Building age matters for earthquake risk in Kenai Peninsula 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.
