Fire reaches the land around Hudson's Hope now and then: 3.1% within 25 km since 1986 (0.08% a year), below the high band. Earthquake risk in Hudson's Hope is ordinary: NRCan’s model puts building losses at $0.020 a year per $1,000 of value, close to the typical town’s $0.030. Hudson's Hope grades B for hazard risk, with wildfire counted against it.
What stands out about Hudson's Hope’s hazards
For Hudson's Hope, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.

Hazard risk in Hudson's Hope: B
The grade weighs Hudson's Hope’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. The burned-area record misses fires under about 10 ha and most grass and farm fires.

The flood map inventory lists nothing for Hudson's Hope
Flood studies whose area touches Hudson's Hope, from NRCan’s inventory, each linked to its owner.
There is no study for Hudson's Hope on the national flood inventory, which is far from complete.
Towns with a flood study on file
Hudson's Hope has no flood study on file, though 76% of towns in British Columbia do (Canada: 58%).
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood is shown here, never graded: a study says where a map exists, not how many of Hudson's Hope’s homes stand in a flood zone.
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.”
Expected shaking damage in Hudson's Hope: $0.020 a year per $1,000

Get ready for what Hudson's Hope faces
What to do about the hazards Hudson's Hope 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.
- 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.
- Has it had a radon test?
- Ask the municipality for flood maps.
- How close is the forest edge?
- 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 Hudson's Hope’s census subdivision (a neighbourhood shows its city’s).
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Hudson's Hope without grading them.
- Radon is a survey. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Hudson's Hope until then.
- Wildfire counts one way. For Hudson's Hope, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
