Fire reaches the land around Yukon, Unorganized now and then: 8.5% within 25 km since 1986 (0.22% a year), below the high band. Earthquakes add more: NRCan’s model puts building losses at $0.17 a year per $1,000 of value, against $0.030 for the typical town. More homes than usual carry radon here, 20% over the guideline where the typical town has 6.6%. Hazard risk gives Yukon, Unorganized a grade of D; its wildfire band pulls it down.
What stands out about Yukon, Unorganized’s hazards
For Yukon, Unorganized, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Yukon, Unorganized faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.
Wildfire
Earthquakes

Flood study
Hazard risk in Yukon, Unorganized: D
Two inputs always count for Yukon, Unorganized, earthquakes and radon; the third, wildfire, counts only against a town.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.

Towns with a flood study on file
Like 58% of towns across Canada, Yukon, Unorganized has a flood study in the inventory.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Yukon, Unorganized’s homes stand in a flood zone.
The inventory’s own caution (NRCan): “The Canada Flood Map (CFM) does not include every flood hazard map in Canada and may be incomplete or contain inaccuracies. It should not be relied upon as the official source of flood mapping information. Furthermore, if a map appears to be missing, this does not necessarily mean that the area has never been mapped. For the official version of a map, updated information, or confirmation of applicable regulations, please contact the local authority responsible for flood mapping.”

Earthquakes cost buildings in Yukon, Unorganized $0.17 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
The typical town loses $0.030 a year to shaking; Yukon, Unorganized loses $0.17, 5.6 times as much.
Shaking damage a year per $1,000 of building value
Canada’s median, $0.030, is the yardstick for Yukon, Unorganized ($0.17): there are too few towns in Yukon for one of their own.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Yukon, Unorganized sits above most of Canada’s 2,611 towns on earthquake risk; 14% are higher.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
Only shaking damage to buildings in Yukon, Unorganized is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Get ready for what Yukon, Unorganized faces
What to do about the hazards Yukon, Unorganized faces, and what to ask before you buy.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Check the address on the flood map.

What this data can and can’t tell you
- Wildfire counts one way. For Yukon, Unorganized, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Yukon, Unorganized without grading them.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Yukon, Unorganized’s census subdivision (a neighbourhood shows its city’s).
- Radon is a survey. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Yukon, Unorganized until then.
