Duncannon, PA
Duncannon wildfire risk explained
Out of every US place USFS scores, Duncannon lands at the 43rd percentile for wildfire risk to structures — modestly above the national average for wildfire risk — a figure built from its 567 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
Separately from the risk score above, Duncannon's burn probability — fire likelihood with no building count factored in — sits at the 41st percentile nationally.
Where Duncannon's buildings actually sit
Most of Duncannon's buildings (93.5%) 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.
Duncannon against the rest of the country
Duncannon's 68th-percentile standing inside Pennsylvania outpaces its 43rd national percentile — this is a hotter spot than most of its own state, even though the state as a whole runs cooler nationally. Among the 31,521 US communities USFS scores, Duncannon ranks 18,129 for wildfire risk (1 is highest) and 16,300 by building count (1 is largest). Within Pennsylvania alone, it ranks 633 of 1,991 places by risk. See the full county-by-county picture for Pennsylvania on its state page.
Duncannon and the insurance market
At the 43rd national percentile, Duncannon rates elevated 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
Because 93.5% of Duncannon's buildings sit in the Indirect zone, sealing the ember pathway (vents, roofing, gutters) is the intervention this page's data actually supports — see the home-hardening guide.
More on how this number was built
Duncannon's 43rd-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what indirect exposure implies beyond Duncannon, see the exposure-zones guide.
