Fire seldom reaches Savane: since 1986, 0.1% of the land within 25 km has burned (0.001% a year). Shaking is a bigger worry than in most places, at $0.20 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Savane a grade of C, from earthquakes and radon alone.
What stands out about Savane’s hazards
Four national sources, each read for Savane: earthquakes, radon, past fires and flood studies.

Hazard risk in Savane: C
Two inputs always count for Savane, earthquakes and radon; the third, wildfire, counts only against a town.
Its place: #161 of 507 in Quebec and #2,110 of 2,589 Canadian towns.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Only 74 homes were tested in the survey area, so the radon share is rough. Small fires and grass fires are largely missing from the national burned-area record.
Few fires near Savane: 0% within 5 km, 0.1% within 25 km
Past fire around Savane’s homes, from the national burned-area record, with the fuel within 5 km.
With 0.001% burned a year, Savane is among the many low-band places (the typical Canadian town 0.000%).
Savane’s homes have had no fire within 5 km since 1986; the closest was 10 km away.
With 0.1% forest fuel within 5 km and 0.5% within 25 km, the land around Savane gives a fire little to burn.

Burn rate a year, towns in Quebec · highest of 513
Savane burns at 0.001% a year, 136th of 513 towns in Quebec; the leader, Mistissini, reaches 0.31%.
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.
Low, like 92% of the country’s 2,610 towns: the land around Savane burns, but slower than in the 7.5% 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.

No flood study is listed for Savane
What Canada’s Flood Map Inventory lists for Savane: who studied flooding and where to see their maps.
There is no study for Savane on the national flood inventory, which is far from complete.
Towns with a flood study on file
Savane has no flood study on file; only 45% of towns in Quebec do, against 58% across Canada.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of Savane’s homes are at risk.
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 Savane $0.20 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; Savane loses $0.20, 6.7 times as much.
Shaking damage a year per $1,000 of building value
Above the middle in Quebec: Savane’s $0.20 against a median of $0.14, with La Pocatière highest at $0.48.

Get ready for what Savane faces
What to do about the hazards Savane 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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
- Is earthquake cover included?
What this data can and can’t tell you
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Savane takes its 2007 health region’s share.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Savane’s figure is its subdivision’s.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Savane’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Savane.

Is radon a problem in Savane?
Around Savane, 74 survey homes were tested and 6.8% came in over 200 Bq/m³, a guide to the area, not to any one home.
