Unalaska's building exposure, zone by zone
USFS classifies 66.9% of Unalaska's buildings as Direct exposure, higher than its 22.8% Indirect share and far above its 10.3% Minimal share — a profile where 346 structures sit close enough to vegetation that lot clearing matters most.

Within Alaska alone, it ranks 320 of 322 places by risk. See the full county-by-county picture for Alaska on its state page.

Hardening a home in Unalaska
With 66.9% of Unalaska in Direct exposure, defensible-space clearing and ember-resistant construction (vents, Class-A roofing) address the exposure this page's own numbers describe, not a generic checklist. See the home-hardening guide.
More on how this number was built
Unalaska's 5th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what direct exposure implies beyond Unalaska, see the exposure-zones guide.
