Fire has left almost no mark near Mahogany: 0% of the land within 25 km since 1986, 0.000% a year. For earthquakes Mahogany is middling, $0.023 a year per $1,000 against $0.030 for the typical town. Radon is about average around Mahogany: 8.1% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Mahogany grades B+ for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Mahogany’s hazards
For Mahogany, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Mahogany grades B+ for hazard risk
Two inputs always count for Mahogany, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #282 of 474 in Alberta and #1,102 of 2,589 Canadian towns.
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.
Wildfire is rare near Mahogany: 0% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Mahogany’s homes, from the national burned-area record, with the fuel within 5 km.
The yearly burn rate around Mahogany is 0.000%, low beside 0.000% for the typical Canadian town.
Since 1986 the nearest fire to Mahogany’s homes came within 16 km, never inside 5 km.
Around Mahogany the forest is thin or far off: 0% of the land within 5 km and 0.4% within 25 km is forest fuel.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in Alberta · highest of 478
Of the 478 towns in Alberta, 386 have a burn rate that rounds to zero, Mahogany among them; Wainwright leads at 1.43% a year.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
The low band holds 92% of Canada’s 2,610 towns, and Mahogany sits at its very bottom; only 7.5% are above it.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Towns with a flood study on file
Mahogany is one of the 46% of towns in Alberta with a flood study on file, fewer than Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for Mahogany to be opened and checked, never turned into a grade.
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.”

Expected shaking damage in Mahogany: $0.023 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Mahogany’s $0.023 is close to the typical town’s $0.030 (0.8 times as much).
Shaking damage a year per $1,000 of building value
The typical town in Alberta expects $0.013 a year; Mahogany expects $0.023, and Black Diamond $0.048.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Around half of Canada’s 2,611 towns expect more shaking damage than Mahogany (54%).
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).

Get ready for what Mahogany faces
What to do about the hazards Mahogany faces, and what to ask before you buy.
- Test for three months in winter.
- Over 200 Bq/m³: fix it.
- Kits are cheap; pros test too.
- Never drive through floodwater.
- Move papers and medicines upstairs.
- Ask whether your street is mapped.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Mahogany.
- 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 Mahogany until then.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Mahogany without grading them.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Mahogany’s included.
Questions about flooding and hazards in Mahogany
Is Mahogany at risk of wildfire?
Less than most of Canada: 0% of the land within 25 km of Mahogany has burned since 1986, the last in 2013, a low band that leaves Risk alone.
How is Mahogany’s Hazard risk Grade worked out?
Hazard risk gives Mahogany B+, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in Mahogany?
In Health Canada’s survey, 8.1% of 86 homes tested in Mahogany’s area were above 200 Bq/m³, though only a test tells you about one house.
Does Mahogany flood?
A flood study covers Mahogany on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
How big is the earthquake risk in Mahogany?
NRCan’s model expects shaking to cost buildings in Mahogany $0.023 a year for every $1,000 of their value, on average over many years.
