Wildfire barely registers for Nackawic, at 0% of the land within 25 km since 1986 (0.000% a year). Earthquake risk in Nackawic is ordinary: NRCan’s model puts building losses at $0.028 a year per $1,000 of value, close to the typical town’s $0.030. Nackawic grades C for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Nackawic’s hazards
Four national sources, each read for Nackawic: earthquakes, radon, past fires and flood studies.
What Nackawic faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Nackawic: C
Two inputs always count for Nackawic, 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.
Wildfire is rare near Nackawic: 0% of the land within 25 km burned since 1986, 0% within 5 km

Burn rate a year, towns in New Brunswick · highest of 61
Among the 61 towns in New Brunswick, Tracadie burns fastest (0.28% a year); Nackawic is with the 16 near zero.
Each bar: the yearly average share of land within 25 km of a town’s homes that burned, 1986–2025 (CWFIS); the seven highest towns of 2,500 people or more.
Like most of Canada’s 2,610 towns (92%), Nackawic is in the low band, with a burn rate of zero to three decimals; 7.5% rank higher.

No flood study is listed for Nackawic
Flood studies whose area touches Nackawic, from NRCan’s inventory, each linked to its owner.
NRCan’s inventory is silent on Nackawic, so any flood map would be the municipality’s own.
Towns with a flood study on file
Flood maps are common in New Brunswick, 93% of towns against 58% nationally, but none in the inventory touches Nackawic.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Listed, not scored: a flood study proves a map exists, not that Nackawic 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.”
Earthquakes cost buildings in Nackawic $0.028 per $1,000 a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.028 per $1,000, Nackawic’s earthquake risk is about the typical Canadian town’s ($0.030; 0.9 times).

More high tests than most: Nackawic sits in a band that only 22% of Canada’s 2,611 towns share, with 4.6% above.
Each bar: the share of Canada’s towns of 2,500 people or more whose survey area had that share of tests over 200 Bq/m³.
Basements, soil and how a house is sealed decide its radon, so in Nackawic only a test can say.

Get ready for what Nackawic faces
What to do about the hazards Nackawic 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. Wildfire is read from the national burned-area record around Nackawic’s homes since 1986, a history of fire that may lower Risk but never raises it.
- 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 Nackawic.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Nackawic’s figure is its subdivision’s.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Nackawic takes its 2007 health region’s share.
