Wildfire isn’t Stanley’s worry: 0% of the land within 25 km burned since 1986 (0.000% a year). For earthquakes Stanley is middling, $0.038 a year per $1,000 against $0.030 for the typical town. Hazard risk gives Stanley a grade of C−, from earthquakes and radon alone.
What stands out about Stanley’s hazards
For Stanley, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Stanley: C−
Two inputs always count for Stanley, earthquakes and radon; the third, wildfire, counts only against a town.
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.
Few fires near Stanley: 0% within 5 km, 0% within 25 km
Past fire around Stanley’s homes, from the national burned-area record, with the fuel within 5 km.
Forty years of fire maps put Stanley at 0.000% a year, low next to the typical Canadian town’s 0.000%.
79% of the land within 5 km of Stanley is forest fuel, close to the 81% 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 New Brunswick · highest of 61
Little or nothing burns around Stanley in a typical year; 16 of the 61 towns in New Brunswick share that, and Tracadie leads at 0.28%.
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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Stanley, at a rounded zero, is far from them.
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.

What Canada’s Flood Map Inventory lists for Stanley: who studied flooding and where to see their maps.
For Stanley the inventory points to Service New Brunswick - GeoNB’s 2020 study, whose map is the one to check.

Towns with a flood study on file
Flood maps are common in New Brunswick: 93% of towns have one, against 58% nationally, and Stanley is among them.
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 Stanley.
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 Stanley $0.038 per $1,000 a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Stanley’s $0.038 is close to the typical town’s $0.030 (1.3 times as much).
Shaking damage a year per $1,000 of building value
Typical for its province: Stanley at $0.038 beside a median in New Brunswick of $0.036, with St. Stephen on top at $0.16.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Around half of Canada’s 2,611 towns expect more shaking damage than Stanley (45%).
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).
Only shaking damage to buildings in Stanley is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Get ready for what Stanley faces
What to do about the hazards Stanley 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?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Stanley’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 Stanley.
- Wildfire counts one way. For Stanley, 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, Stanley takes its 2007 health region’s share.
Questions about flooding and hazards in Stanley
Is Stanley at risk of wildfire?
Hardly at all on record: 0% of the land within 25 km of Stanley since 1986, a low band, though small grass fires aren’t mapped.
Does Stanley flood?
The inventory lists a study touching Stanley; whether a given street floods is on that map, not in the grade.
How is Stanley’s Hazard risk Grade worked out?
Hazard risk gives Stanley C−, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in Stanley?
Around Stanley, 112 survey homes were tested and 17% came in over 200 Bq/m³, a guide to the area, not to any one home.
How big is the earthquake risk in Stanley?
In NRCan’s seismic model, Stanley’s buildings lose $0.038 per $1,000 of value in an average year.
