Wildfire isn’t East Broughton’s worry: 0% of the land within 25 km burned since 1986 (0.000% a year). Earthquake risk in East Broughton is ordinary: NRCan’s model puts building losses at $0.042 a year per $1,000 of value, close to the typical town’s $0.030. East Broughton grades C for hazard risk; wildfire is low here, so it earns no credit.
What stands out about East Broughton’s hazards
For East Broughton, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What East Broughton faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in East Broughton: C
Risk averages earthquakes and radon; wildfire joins only where it pulls the average down, so a town like East Broughton with little fire nearby would get no credit for it.
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 East Broughton
What Canada’s Flood Map Inventory lists for East Broughton: who studied flooding and where to see their maps.
The inventory has nothing for East Broughton, but a local or conservation-authority map may still exist.
Towns with a flood study on file
No study touches East Broughton; in Quebec, 45% of towns have one, below Canada’s 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
The grade leaves flood out, since a study area says nothing about how many of East Broughton’s homes are at risk.
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.”

Get ready for what East Broughton faces
What to do about the hazards East Broughton 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 East Broughton, 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. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for East Broughton is its health region’s, the survey’s design unit.
- 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 East Broughton.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for East Broughton’s census subdivision (a neighbourhood shows its city’s).
