Little of the land around Saint-Fulgence has burned: 0.3% within 25 km since 1986, or 0.007% a year. Shaking is a bigger worry than in most places, at $0.14 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Saint-Fulgence a grade of B; its wildfire band pulls it down.
What stands out about Saint-Fulgence’s hazards
Four national sources, each read for Saint-Fulgence: earthquakes, radon, past fires and flood studies.
What Saint-Fulgence faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Earthquakes
Radon
Flood study
Saint-Fulgence grades B for hazard risk
Two inputs always count for Saint-Fulgence, 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 radon share rests on 72 home tests in the survey area, so a few homes move it. Small fires and grass fires are largely missing from the national burned-area record.
Wildfire is rare near Saint-Fulgence: 0.3% of the land within 25 km burned since 1986, 0% within 5 km
Fires mapped since 1986 around where Saint-Fulgence’s residents live, and the fuel next to their homes.
Saint-Fulgence burns at 0.007% a year, low against 0.000% for the typical Canadian town.
No fire has burned within 5 km of Saint-Fulgence’s homes since 1986; the nearest burn is 6.3 km away.
Forest fuel is spread evenly around Saint-Fulgence: 66% within 5 km, 65% within 25 km.
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 Quebec · highest of 514
In the top quarter in Quebec: Saint-Fulgence ranks 23rd of 514 at 0.007% a year, with Mistissini first at 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.
Saint-Fulgence is in the low band with 92% of Canada’s 2,610 towns; 7.5% sit in moderate or higher.
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.

The flood map inventory lists nothing for Saint-Fulgence
Flood studies whose area touches Saint-Fulgence, from NRCan’s inventory, each linked to its owner.
An empty entry for Saint-Fulgence on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
Only 45% of towns in Quebec have a flood study, short of Canada’s 58%, and Saint-Fulgence is not among them.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Listed, not scored: a flood study proves a map exists, not that Saint-Fulgence floods.
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.”
High seismic risk in Saint-Fulgence: $0.14 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.14 per $1,000, Saint-Fulgence carries roughly 4.8 times the typical Canadian town’s earthquake risk ($0.030).
Shaking damage a year per $1,000 of building value
Typical for its province: Saint-Fulgence at $0.14 beside a median in Quebec of $0.14, with La Pocatière on top at $0.48.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
More earthquake risk than most: only 20% of Canada’s 2,611 towns are above Saint-Fulgence.

Roads, pipes and bridges aren’t in Saint-Fulgence’s figure, nor landslides or tsunami: it is buildings and shaking.

2.8% of homes tested around Saint-Fulgence are over the radon guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
Where the typical Canadian town has 6.6% of homes over the guideline, Saint-Fulgence’s area has fewer, 2.8%. Saint-Fulgence shares its radon tests numbers with the rest of the Saguenay - Lac-Saint-Jean health region.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Around Saint-Fulgence, 2.8% of tests were over 200 Bq/m³, under the median in Quebec (8.2%); 1.4% were over 600.
Health Canada radon survey (2009–2011), by 2007 health region; medians of towns of 2,500 people or more.
The quietest radon band, under 5%, holds 37% of Canada’s 2,611 towns and Saint-Fulgence; 63% sit higher.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
The share describes the area, not a house: in Saint-Fulgence as anywhere, test to be sure.

Get ready for what Saint-Fulgence faces
What to do about the hazards Saint-Fulgence 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
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Saint-Fulgence without grading them.
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Saint-Fulgence’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 Saint-Fulgence until then.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Saint-Fulgence’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
Questions about flooding and hazards in Saint-Fulgence
How is Saint-Fulgence’s Hazard risk Grade worked out?
Hazard risk gives Saint-Fulgence B, weighing earthquakes and radon and counting wildfire only against it.
How big is the earthquake risk in Saint-Fulgence?
About $0.14 a year per $1,000 of building value, NRCan’s long-run expectation for Saint-Fulgence.
Does Saint-Fulgence flood?
Nothing is listed for Saint-Fulgence on the national inventory (0); local maps may still exist with the municipality.
Is Saint-Fulgence at risk of wildfire?
Less than most of Canada: 0.3% of the land within 25 km of Saint-Fulgence has burned since 1986, the last in 2025, a low band that leaves Risk alone.
Is radon a problem in Saint-Fulgence?
In Health Canada’s survey, 2.8% of 72 homes tested in Saint-Fulgence’s area were above 200 Bq/m³, though only a test tells you about one house.
