Volcano, CA
Volcano wildfire risk explained
USFS scores Volcano at the 100th national percentile for wildfire risk to structures (in USFS's highest wildfire-risk band nationally), a figure built from 148 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Volcano at the 99th national percentile — 0 points below its risk-to-structures score, a gap driven by how much is actually built there.
Where Volcano's buildings actually sit
USFS classifies 89.2% of Volcano's buildings as Direct exposure, higher than its 10.8% Indirect share and far above its 0% Minimal share — a profile where 132 structures sit close enough to vegetation that lot clearing matters most.
Where Volcano ranks
Volcano scores 100th nationally and 95th within California — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Volcano ranks 131 for wildfire risk (1 is highest) and 26,943 by building count (1 is largest). Within California alone, it ranks 88 of 1,570 places by risk. See the full county-by-county picture for California on its state page.
Shopping for coverage in Volcano
Volcano's 100th-percentile score lands in California, the only two states requiring a wildfire disclosure at sale. California's surplus-lines homeowners market passed 300,000 policies for the first time in 2025, driven by carriers pulling back from wildfire-exposed areas statewide. The disclosure-law guide covers what it requires.
What would actually reduce this score
Because Direct exposure dominates in Volcano (89.2%), the highest-leverage fix is defensible space, not roofing or vents alone — covered in the home-hardening guide.
