Hazard risk in Saint-Gédéon-de-Beauce: C−
For Saint-Gédéon-de-Beauce, 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. The burned-area record misses fires under about 10 ha and most grass and farm fires.

Get ready for what Saint-Gédéon-de-Beauce faces
Practical steps for Saint-Gédéon-de-Beauce’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. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Saint-Gédéon-de-Beauce.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Saint-Gédéon-de-Beauce’s census subdivision (a neighbourhood shows its city’s).
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Saint-Gédéon-de-Beauce takes its 2007 health region’s share.
- Wildfire counts one way. For Saint-Gédéon-de-Beauce, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
