Adak, AK
Adak, AK's wildfire risk, in USFS's own numbers
USFS scores Adak at the 6th national percentile for wildfire risk to structures (among the lower wildfire-risk places nationally), a figure built from 392 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Adak at the 6th national percentile — 1 points below its risk-to-structures score, a gap driven by how much is actually built there.
Adak's building exposure, zone by zone
Most of Adak's buildings (43.4%) sit in the Indirect zone, where wind-blown embers rather than flame front are the mechanism USFS is scoring — ember-resistant vents and non-combustible roofing are the interventions this pattern favors, more than defensible space alone.
Adak against the rest of the country
There's little gap between Adak's 6th national percentile and its 3rd percentile inside Alaska, which means the state comparison mostly confirms what the national score already shows. Among the 31,521 US communities USFS scores, Adak ranks 29,551 for wildfire risk (1 is highest) and 19,360 by building count (1 is largest). Within Alaska alone, it ranks 310 of 322 places by risk. See the full county-by-county picture for Alaska on its state page.
Adak and the insurance market
At the 6th national percentile, Adak rates low for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Lowering exposure, not just insuring around it
Adak's 43.4% Indirect-exposure share points at embers, not flame contact, as the main pathway — ember-resistant vents and non-combustible roofing rank ahead of defensible space here. Detail in the home-hardening guide.
Where Adak's figures come from
Adak's 6th-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. The exposure-zones guide covers what Adak's dominant indirect exposure actually means, with real examples from across the dataset.
