Fire seldom reaches Stoney 142, 143, 144: since 1986, 1% of the land within 25 km has burned (0.03% a year). For earthquakes Stoney 142, 143, 144 is middling, $0.035 a year per $1,000 against $0.030 for the typical town. Radon is about average around Stoney 142, 143, 144: 8.1% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Stoney 142, 143, 144 a grade of B; its wildfire band pulls it down.

Hazard risk in Stoney 142, 143, 144: B
Earthquake risk and radon make Stoney 142, 143, 144’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
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.

Get ready for what Stoney 142, 143, 144 faces
Practical steps for Stoney 142, 143, 144’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?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Stoney 142, 143, 144 takes its 2007 health region’s share.
- 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 Stoney 142, 143, 144.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Stoney 142, 143, 144’s included.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Stoney 142, 143, 144.

How is Stoney 142, 143, 144’s Hazard risk Grade worked out?
Stoney 142, 143, 144’s Hazard risk grade is B, built on earthquakes and radon with a one-sided wildfire input.
Is radon a problem in Stoney 142, 143, 144?
8.1% of the 86 homes Health Canada tested around Stoney 142, 143, 144 topped the guideline; your own house needs its own test.
