Risk Overview

About Natural Disaster Risk in Copper River Census Area, Alaska

Relatively low risk with wildfire intensity

Copper River Census Area's 39.95 composite score falls below the national average despite the state's third-highest wildfire risk (83.65). The region's minimal flood and tornado exposure helps offset the substantial fire threat.

Moderate-risk tier in Alaska

Copper River Census Area ranks slightly above Alaska's 35.22 state average at 39.95, placing it in the state's moderate-risk category. It's riskier than coastal boroughs but significantly safer than Anchorage Municipality.

Wildfire sets it apart from peers

Copper River Census Area's wildfire risk of 83.65 ranks third-highest statewide and vastly exceeds nearby Chugach Census Area (1.30). This exceptional fire exposure makes Copper River substantially riskier than its closest geographic neighbors.

Wildfire and earthquake are dual threats

Wildfire risk dominates at 83.65—third-worst in Alaska—while earthquake exposure at 77.77 poses a secondary threat. Flood (1.91) and tornado (0.38) risks remain minimal, making fire and seismic hazards the clear focus.

Prioritize wildfire and earthquake protection

Create defensible space around your home, maintain fire-resistant landscaping, and clear gutters to mitigate the 83.65 wildfire risk. Add earthquake insurance to standard homeowners coverage to address the area's significant seismic exposure.

Risk Advisory: Copper River Census Area

Risk Verdict

Copper River Census Area sits in the lower tier of U.S. counties for natural disaster exposure, ranked at the 40th percentile nationally. Copper River Census Area's 40th percentile ranking reflects aggregate hazard exposure; individual households still benefit from knowing the specific hazard types most relevant to their property's location.

Hazard Breakdown

Wildfire risk is Copper River Census Area's dominant natural hazard, ranked at the 84th percentile nationally under FEMA's National Risk Index. Earthquake ranks second at the 78th percentile nationally. Additional tracked hazards include flood (2th percentile), tornado (0th percentile).

Preparedness Context

At the 84th percentile nationally for wildfire risk, Copper River Census Area households benefit from creating defensible space — a buffer of reduced vegetation around structures — and reviewing whether homeowners insurance covers wildfire damage in this region. Earthquake, which ranks at the 78th percentile nationally, is a secondary concern for Copper River Census Area that becomes most relevant in months outside the fire season. Enrolling in the county's wireless emergency alert system and keeping a vehicle at least half-full during peak fire season are low-cost habits that dramatically reduce evacuation lag time for Copper River Census Area residents.

Regional Context

Copper River Census Area tracks the Alaska county average closely, sitting 4.7 composite points above the state mean — neither a standout high-risk nor low-risk county within Alaska.

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 Copper River Census Area higher risk than average?
Copper River Census Area's composite risk score of 40th percentile is above the Alaska state average of 35th percentile. This elevated risk is driven by wildfire exposure (84th percentile), along with earthquake risk. Geographic location, terrain, climate patterns, and proximity to flood zones or fault lines all influence a county's risk profile.
