Fire seldom reaches Clanwilliam-Erickson: since 1986, 0.9% of the land within 25 km has burned (0.02% a year). Earthquakes matter little: NRCan’s model puts building losses at $0.005 a year per $1,000 of value, against $0.030 for the typical town. Hazard risk gives Clanwilliam-Erickson a grade of B−; its wildfire band pulls it down.

Clanwilliam-Erickson grades B− for hazard risk
The grade weighs Clanwilliam-Erickson’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. The burned-area record misses fires under about 10 ha and most grass and farm fires.

No flood study is listed for Clanwilliam-Erickson
Flood studies whose area touches Clanwilliam-Erickson, from NRCan’s inventory, each linked to its owner.
NRCan’s inventory is silent on Clanwilliam-Erickson, so any flood map would be the municipality’s own.
Towns with a flood study on file
Mapping in Manitoba reaches 18% of towns, below the 58% across Canada, and not Clanwilliam-Erickson.

Flood studies don’t enter the grade; they are listed so you can open the official map for Clanwilliam-Erickson.
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.”
Little shaking expected in Clanwilliam-Erickson: $0.005 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Clanwilliam-Erickson’s $0.005 is a fraction of the typical town’s $0.030 (0.2 times as much): quiet ground by Canadian standards.
Shaking damage a year per $1,000 of building value
Neither high nor low in Manitoba: Clanwilliam-Erickson’s $0.005 sits by the median of $0.006, while Virden reaches $0.007.

Get ready for what Clanwilliam-Erickson faces
What to do about the hazards Clanwilliam-Erickson 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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. For Clanwilliam-Erickson, 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. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Clanwilliam-Erickson 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 Clanwilliam-Erickson’s census subdivision (a neighbourhood shows its city’s).
- 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 Clanwilliam-Erickson.
