The burned-area map is nearly blank around Denmark, 0% within 25 km since 1986, 0.000% a year. NRCan expects $0.049 of shaking damage a year per $1,000 of buildings in Denmark, near the typical $0.030. Hazard risk gives Denmark a grade of C−, from earthquakes and radon alone.
What stands out about Denmark’s hazards
For Denmark, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Denmark faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Denmark: C−
Seismic risk and radon set Denmark’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. The burned-area record misses fires under about 10 ha and most grass and farm fires.
Few fires near Denmark: 0% within 5 km, 0% within 25 km
Fires mapped since 1986 around where Denmark’s residents live, and the fuel next to their homes.
Fire claims 0.000% of the land around Denmark each year, a low band, with the typical Canadian town at 0.000%.
The closest burn since 1986 lies 14 km from Denmark’s homes, none within 5 km.
Forest fuel covers 47% of the land close to Denmark and 58% across 25 km.
Shares of land within 5 and 25 km of populated blocks: burned at least once in 1986–2025 (CWFIS burned-area composite), forest fuel and grass (fire behaviour fuel types, 2026, 250 m grid).
Burn rate a year, towns in New Brunswick · highest of 61
Near-zero burning puts Denmark with 16 of the 61 towns in New Brunswick, far below Tracadie 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.
Measured against 2,610 towns, Denmark is in the largest group, low (92%), and at its floor, while 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 studies whose area touches Denmark, from NRCan’s inventory, each linked to its owner.
For Denmark the inventory points to Service New Brunswick - GeoNB’s 2020 study, whose map is the one to check.

Towns with a flood study on file
Denmark is one of the 93% of towns in New Brunswick with a flood study on file; across Canada it is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood studies don’t enter the grade; they are listed so you can open the official map for Denmark.
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 Denmark: $0.049 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Denmark’s $0.049 is close to the typical town’s $0.030 (1.6 times as much).
Shaking damage a year per $1,000 of building value
At $0.049, Denmark is above the typical town in New Brunswick ($0.036); St. Stephen has the most at $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.
In the upper part of Canada’s range: 31% of its 2,611 towns expect more damage than Denmark.
Each column: the share of Canada’s towns of 2,500 people or more in that range of yearly loss per $1,000 (NRCan, 2022).
Only shaking damage to buildings in Denmark is counted; landslides, liquefaction, tsunami and fire after a quake aren’t.

Radon runs high around Denmark: 17% of tested homes over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Source area for radon tests: the Region 3 health region
At 17% over the guideline, the area around Denmark beats the typical Canadian town’s 6.6%.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Ordinary for towns in New Brunswick at 17% over 200 Bq/m³ (20% is the median), the area around Denmark had 7.1% over 600.

More high tests than most: Denmark 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.

Where to get warnings in Denmark
Alerts for Denmark come from Environment and Climate Change Canada and, for emergencies, Alert Ready.
| Alert | What it means |
|---|---|
| Warning | Severe weather is happening or about to: act now. |
| Watch | Conditions favour severe weather: be ready. |
| Advisory | Weather that is less severe but could disrupt the day. |
| Special weather statement | Unusual weather worth knowing about. |
| Special air quality statement | Poor air, often wildfire smoke. |
Fire danger and active fires near Denmark are mapped daily by the Canadian Wildland Fire Information System; evacuation orders come from the municipality or province.

How Denmark’s neighbours compare on hazards
The same four hazards for the places next door.

|---|---|---|---|---|
| Denmark | Low | $0.049 | 17% | Yes |
| Drummond 2,113 · 10.0 km | Low | $0.055 | 29% | Yes |
| Grand Falls 1,114 · 11 km | Low | $0.046 | 29% | Yes |
| Gordon 1,576 · 12 km | Low | $0.067 | 17% | None listed |
| Grand Falls / Grand-Sault 5,465 · 14 km | Low | $0.048 | 29% | Yes |
| Plaster Rock 1,062 · 16 km | Low | $0.075 | 17% | None listed |
Grand Falls burns a little more than Denmark, in the same low band (low here).
Radon is the survey area’s figure, so neighbours in one area share it.
Get ready for what Denmark faces
Practical steps for Denmark’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, Denmark takes its 2007 health region’s share.
- Wildfire counts one way. For Denmark, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Denmark’s census subdivision (a neighbourhood shows its city’s).
- 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 Denmark.
Questions about flooding and hazards in Denmark
Is radon a problem in Denmark?
The area’s survey found 17% of 112 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Denmark.
How big is the earthquake risk in Denmark?
Expected earthquake damage in Denmark comes to $0.049 a year for each $1,000 that buildings are worth.
Is Denmark at risk of wildfire?
Some, but Denmark’s low band (0% of nearby land burned since 1986, latest 2013) is short of the level that counts.
How is Denmark’s Hazard risk Grade worked out?
Hazard risk gives Denmark C−, weighing earthquakes and radon and counting wildfire only against it.
Does Denmark flood?
The inventory lists a study touching Denmark; whether a given street floods is on that map, not in the grade.
