Some 5.2% of the land within 25 km of Electoral Area H, Cariboo has burned since 1986; at 0.13% a year that is moderate, not high. Earthquakes matter little: NRCan’s model puts building losses at $0.015 a year per $1,000 of value, against $0.030 for the typical town. Radon is about average around Electoral Area H, Cariboo: 6.4% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Electoral Area H, Cariboo a grade of A−; its wildfire band pulls it down.
What stands out about Electoral Area H, Cariboo’s hazards
Four national sources, each read for Electoral Area H, Cariboo: earthquakes, radon, past fires and flood studies.

Electoral Area H, Cariboo grades A− for hazard risk
Two inputs always count for Electoral Area H, Cariboo, 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. Small fires and grass fires are largely missing from the national burned-area record.
Some fire around Electoral Area H, Cariboo: 5.2% of the land within 25 km since 1986, 3.2% within 5 km
Fires mapped since 1986 around where Electoral Area H, Cariboo’s residents live, and the fuel next to their homes.
At 0.13% of the land a year, Electoral Area H, Cariboo’s burn rate is moderate; the typical Canadian town sees 0.000%.
The nearer ring around Electoral Area H, Cariboo is less wooded (71% forest fuel) than the land out to 25 km (78%).

Listed, not scored: a flood study proves a map exists, not that Electoral Area H, Cariboo floods.
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 Electoral Area H, Cariboo faces
What to do about the hazards Electoral Area H, Cariboo faces, and what to ask before you buy.
- Clear needles and wood nearby.
- Keep a grab-and-go bag ready.
- In smoke, stay in; filter air.

What this data can and can’t tell you
- Earthquakes are modelled. Shaking damage is modelled from the ground, the buildings and the odds of each quake, and published for whole subdivisions such as Electoral Area H, Cariboo’s.
- 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 Electoral Area H, Cariboo.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Electoral Area H, Cariboo is its health region’s, the survey’s design unit.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Electoral Area H, Cariboo’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
