Risk Overview
Overall natural disaster risk in Hoonah-Angoon Census Area is very low, with a National Risk Index score of 14.3 out of 100 — placing it in the 14th national percentile and among the lowest-risk counties in the country. The score blends Expected Annual Loss, Social Vulnerability, and Community Resilience across all 18 FEMA hazard types.
Risk here concentrates in landslide (downhill movement of rock, soil, and debris on unstable slopes) at Medium risk — $152K in expected annual loss and about 37.15 events per year; avalanche (fast-moving snow and debris sliding down steep mountain slopes) at Very High risk — $2M in expected annual loss and about 0.17 events per year; and earthquake (ground shaking from sudden movement along geologic faults) at Low risk — $560K in expected annual loss and about 0.09 events per year. Across all hazards, FEMA estimates $3M in expected annual loss for a population of 2K.
Beyond physical exposure, Hoonah-Angoon Census Area has a very high social vulnerability rating (how susceptible the population is to harm) and a very low community resilience rating (its capacity to prepare for and recover from disasters). That combination — a more vulnerable population with limited resilience — can amplify the human cost of any given event.
