Little of the land around Beaurivage has burned: 0.1% within 25 km since 1986, or 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). Beaurivage grades C for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Beaurivage’s hazards
For Beaurivage, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Beaurivage grades C for hazard risk
Seismic risk and radon set Beaurivage’s grade, wildfire can drag it down, and flood mapping stays out of it.
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. The radon share rests on 74 home tests in the survey area, so a few homes move it. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Wildfire is rare near Beaurivage: 0.1% of the land within 25 km burned since 1986, 0% within 5 km

No flood study is listed for Beaurivage
What Canada’s Flood Map Inventory lists for Beaurivage: who studied flooding and where to see their maps.
NRCan’s inventory is silent on Beaurivage, so any flood map would be the municipality’s own.

Mapping in Quebec reaches 45% of towns, below the 58% across Canada, and not Beaurivage.

Flood mapping is shown for Beaurivage 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.”
Shaking is Beaurivage’s costliest hazard: $0.20 a year per $1,000
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Roughly 6.7 times the typical $0.030: Beaurivage’s $0.20 marks real seismic exposure.

Get ready for what Beaurivage faces
Practical steps for Beaurivage’s hazards, most pressing first.
- 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. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Beaurivage.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Beaurivage takes its 2007 health region’s share.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Beaurivage’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Beaurivage, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
Questions about flooding and hazards in Beaurivage
Is Beaurivage at risk of wildfire?
Some, but Beaurivage’s low band (0.1% of nearby land burned since 1986, latest 2019) is short of the level that counts.
Is radon a problem in Beaurivage?
The area’s survey found 6.8% of 74 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Beaurivage.
How is Beaurivage’s Hazard risk Grade worked out?
Beaurivage’s Hazard risk grade is C, built on earthquakes and radon with a one-sided wildfire input.
How big is the earthquake risk in Beaurivage?
In NRCan’s seismic model, Beaurivage’s buildings lose $0.20 per $1,000 of value in an average year.
Does Beaurivage flood?
The inventory has 0 studies for Beaurivage, and an empty list isn’t a clean bill: the municipality holds any flood maps.
