Little of the land around Weldford has burned: 0.2% within 25 km since 1986, or 0.004% a year. Shaking is about as much of a worry in Weldford as in most places, at $0.041 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Weldford a grade of C−, from earthquakes and radon alone.
What stands out about Weldford’s hazards
Four national sources, each read for Weldford: earthquakes, radon, past fires and flood studies.
What Weldford faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Weldford: C−
Seismic risk and radon set Weldford’s grade, wildfire can drag it down, and flood mapping stays out of it.
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.
Little of the land around Weldford has burned: 0% within 5 km, 0.2% within 25 km since 1986
Fires mapped since 1986 around where Weldford’s residents live, and the fuel next to their homes.
At 0.004% of the land a year, Weldford’s burn rate is in the low band; the typical Canadian town sees 0.000%.
The 5 km ring around Weldford’s homes is clear of burns since 1986, the nearest 9.1 km out.
About as much forest grows next to Weldford’s homes (87% within 5 km) as across 25 km (87%).

Burn rate a year, towns in New Brunswick · highest of 61
At 0.004% a year, Weldford ranks 25th of the 61 towns in New Brunswick; Tracadie leads at 0.28%.
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.
Beside 2,610 Canadian towns, Weldford reads low, with 92% of them; only 7.5% rank higher.
Bands of the yearly burn rate: low under 0.05%, moderate under 0.25%, high under 1%, very high 1% or more; towns of 2,500 people or more.

Flood mapping is shown for Weldford to be opened and checked, never turned into a grade.
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.”

Ordinary seismic risk in Weldford: $0.041 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Earthquake losses in Weldford, $0.041 per $1,000, are in line with the typical $0.030 (1.4 times).
Shaking damage a year per $1,000 of building value
Shaking damage around Weldford runs at $0.041 a year, near the $0.036 of the typical town in New Brunswick; St. Stephen has $0.16.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Middle of the pack: 43% of Canada’s 2,611 towns have more earthquake risk than Weldford.

Test for radon in Weldford: 20% of area homes were over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
A higher share than most: 20% of tested homes around Weldford, the typical Canadian town 6.6%. Behind radon tests sits data gathered across the Region 1 health region, with Weldford one part of it.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
3.7% of tests around Weldford passed 600 Bq/m³; over 200, its 20% matches the median in New Brunswick, 20%.

More high tests than most: Weldford 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.
The share describes the area, not a house: in Weldford as anywhere, test to be sure.

Get ready for what Weldford faces
Practical steps for Weldford’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?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Weldford takes its 2007 health region’s share.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Weldford’s figure is its subdivision’s.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Weldford’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 Weldford.
Questions about flooding and hazards in Weldford
Does Weldford flood?
The inventory lists a study touching Weldford; whether a given street floods is on that map, not in the grade.
Is radon a problem in Weldford?
20% of the 107 homes Health Canada tested around Weldford topped the guideline; your own house needs its own test.
How is Weldford’s Hazard risk Grade worked out?
Weldford grades C− for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
Is Weldford at risk of wildfire?
Not much by Canadian standards: Weldford’s band is low, with 0.2% of the land within 25 km burned since 1986 (last in 2025), so wildfire doesn’t change its grade.
How big is the earthquake risk in Weldford?
About $0.041 a year per $1,000 of building value, NRCan’s long-run expectation for Weldford.
