Risk Overview
About Natural Disaster Risk in Dillingham Census Area, Alaska
Dillingham's disaster risk: Below average nationally
Dillingham Census Area scores 35.69 on the composite risk scale, ranking it as Very Low and nearly identical to Alaska's state average of 35.22. This puts the county well below the national average, meaning residents face fewer natural hazards than most U.S. counties.
Middle of the pack in Alaska
Among Alaska's counties, Dillingham ranks in the middle range for overall disaster risk, with a score just above the state average. The county sits between lower-risk Southeast Alaska communities and higher-risk interior regions.
Safer than interior peers, similar to coastal areas
Dillingham's risk profile is comparable to other Southwest Alaska communities and significantly lower than Fairbanks North Star Borough (88.52) and Kenai Peninsula Borough (93.03). Like coastal neighbors Hoonah-Angoon (14.31), Dillingham benefits from its geographic isolation.
Earthquakes and wildfires pose greatest threats
Earthquake risk dominates at 75.00, reflecting Alaska's position on the Pacific Ring of Fire, while wildfire risk reaches 62.15—the county's second major concern during summer months. Flood risk (3.09) and tornado risk (0.64) remain minimal threats.
Earthquake and fire insurance are essential here
Standard homeowners insurance doesn't cover earthquake or wildfire damage—you'll need separate policies for these hazards. Consider earthquake coverage given the 75.00 risk score and wildfire mitigation around your property, especially if you're in a forest-adjacent area.
