Thor, IA
Thor, IA's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Thor lands at the 1st percentile for wildfire risk to structures — among the lower wildfire-risk places nationally — a figure built from its 130 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Thor at the 1st percentile, close to its 1st-percentile risk score.
What "at risk" means for the buildings here
87.7% of Thor's 130 buildings sit in USFS's Minimal exposure zone, with only 12.3% rated Direct — risk here comes from regional burn probability more than proximity to burnable vegetation at the structure itself.
How Thor compares
Thor scores 1st nationally and 1st within Iowa — close enough that its state context doesn't change the picture the national number already gives. Among the 31,521 US communities USFS scores, Thor ranks 31,207 for wildfire risk (1 is highest) and 27,712 by building count (1 is largest). Within Iowa alone, it ranks 1,011 of 1,017 places by risk. See the full county-by-county picture for Iowa on its state page.
Shopping for coverage in Thor
Thor's low wildfire rating (1st percentile) isn't the kind of score driving the carrier pullback making news in the highest-risk Western markets — but a standard homeowners quote is still worth comparing on its own terms.
Hardening a home in Thor
With 87.7% of buildings rated Minimal exposure, Thor gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
More on how this number was built
Thor's 1st-percentile score and its burn-probability figure both come from the same USFS workbook, documented in the methodology guide. For more on what minimal exposure implies beyond Thor, see the exposure-zones guide.
