Since 1986 almost nothing has burned near Roland: 0% of the land within 25 km, or 0.001% 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. Roland grades B− for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Roland’s hazards
Four national sources, each read for Roland: earthquakes, radon, past fires and flood studies.
What Roland faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Roland: B−
For Roland, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
How sure: Earthquake losses are a model’s expectation over many years, not a forecast for any one. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Roland has burned: 0% within 5 km, 0% within 25 km since 1986
Past fire around Roland’s homes, from the national burned-area record, with the fuel within 5 km.
Low by Canadian standards: 0.001% of the land a year around Roland, 0.000% for the typical Canadian town.
Fire has stayed at least 16 km from Roland’s homes since 1986.
With 0% forest fuel within 5 km and 0% within 25 km, the land around Roland gives a fire little to burn.

No flood study is listed for Roland
What Canada’s Flood Map Inventory lists for Roland: who studied flooding and where to see their maps.
The inventory has nothing for Roland, but a local or conservation-authority map may still exist.
Towns with a flood study on file
Mapping in Manitoba reaches 18% of towns, below the 58% across Canada, and not Roland.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood studies don’t enter the grade; they are listed so you can open the official map for Roland.
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.”
Low seismic risk in Roland: $0.005 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
At $0.005 per $1,000, Roland carries 0.2 times the typical Canadian town’s earthquake risk ($0.030): low.
Shaking damage a year per $1,000 of building value
Earthquake risk around Roland ($0.005) matches the middle in Manitoba ($0.006), far from Virden’s $0.007.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
At the bottom of Canada’s range, Roland has 96% of the 2,611 towns above it.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
The loss is to Roland’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

43% of homes tested around Roland are over the radon guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline. · Measured across the Central health region: radon tests
At 43% over the guideline, the area around Roland beats the typical Canadian town’s 6.6%.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
More homes top the guideline around Roland (43%) than in the typical town in Manitoba (12%); 7.4% went over 600.

No band is higher: Roland is among the 1.5% of Canada’s towns with 30% or more of tests over 200 Bq/m³.
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 Roland as anywhere, test to be sure.

Fire is no heavier anywhere nearby than around Roland (low), with Carman next at low.
Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Roland faces
Practical steps for Roland’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
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Roland’s figure is its subdivision’s.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Roland is its health region’s, the survey’s design unit.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Roland’s homes since 1986, a history of fire that may lower Risk but never raises it.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Roland.
Questions about flooding and hazards in Roland
Is radon a problem in Roland?
43% of the 108 homes Health Canada tested around Roland topped the guideline; your own house needs its own test.
How is Roland’s Hazard risk Grade worked out?
Roland’s Hazard risk grade is B−, built on earthquakes and radon with a one-sided wildfire input.
How big is the earthquake risk in Roland?
NRCan’s model expects shaking to cost buildings in Roland $0.005 a year for every $1,000 of their value, on average over many years.
Is Roland at risk of wildfire?
Not much by Canadian standards: Roland’s band is low, with 0% of the land within 25 km burned since 1986 (last in 2000), so wildfire doesn’t change its grade.
Does Roland flood?
No study on Canada’s Flood Map Inventory covers Roland (0), which doesn’t mean it has never been mapped, so ask the municipality.
