Hazards in Valhalla: wildfire low, radon over the guideline in 12% of tested homes
Wildfire isn’t Valhalla’s worry: 0% of the land within 25 km burned since 1986 (0.001% a year). Earthquakes matter little: NRCan’s model puts building losses at $0.006 a year per $1,000 of value, against $0.030 for the typical town. Hazard risk gives Valhalla a grade of B+; its wildfire band pulls it down.
What stands out about Valhalla’s hazards
For Valhalla, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Valhalla faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Valhalla: B+
Earthquake risk and radon make Valhalla’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #10 of 185 in Manitoba and #940 of 2,589 Canadian towns.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Only 66 homes were tested in the survey area, so the radon share is rough. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Valhalla: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Valhalla’s residents live, and the fuel next to their homes.
With 0.001% burned a year, Valhalla is among the many low-band places (the typical Canadian town 0.000%).
No fire has burned within 5 km of Valhalla’s homes since 1986; the nearest burn is 14 km away.
Forest fuel is scarce around Valhalla: 0% of the land within 5 km, 0.1% 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 Manitoba · highest of 189
Valhalla ranks 31st of the 189 towns in Manitoba for burn rate, at 0.001% a year; Flin Flon (Part) leads with 1.68%.
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 Valhalla 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.

The flood map inventory lists nothing for Valhalla
Flood studies whose area touches Valhalla, from NRCan’s inventory, each linked to its owner.
Nationally, Valhalla has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Mapping in Manitoba reaches 18% of towns, below the 58% across Canada, and not Valhalla.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Nothing here counts toward Risk; the studies are pointers to the maps their owners keep for Valhalla.
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 Valhalla just $0.006 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.006 per $1,000, Valhalla carries 0.2 times the typical Canadian town’s earthquake risk ($0.030): low.

Get ready for what Valhalla faces
Practical steps for Valhalla’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.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Valhalla floods.
- Wildfire counts one way. For Valhalla, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Valhalla sits in.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Valhalla’s census subdivision (a neighbourhood shows its city’s).
Questions about flooding and hazards in Valhalla
Is Valhalla at risk of wildfire?
Not much by Canadian standards: Valhalla’s band is low, with 0% of the land within 25 km burned since 1986 (last in 2012), so wildfire doesn’t change its grade.
Is radon a problem in Valhalla?
12% of the 66 homes Health Canada tested around Valhalla topped the guideline; your own house needs its own test.
Does Valhalla flood?
No study on Canada’s Flood Map Inventory covers Valhalla (0), which doesn’t mean it has never been mapped, so ask the municipality.
How is Valhalla’s Hazard risk Grade worked out?
Valhalla’s Hazard risk grade is B+, built on earthquakes and radon with a one-sided wildfire input.
How big is the earthquake risk in Valhalla?
Expected earthquake damage in Valhalla comes to $0.006 a year for each $1,000 that buildings are worth.
