Wildfire is a moderate presence around Maugerville: 5.7% of the land within 25 km has burned since 1986, 0.23% a year, short of the band that counts against Risk. For earthquakes Maugerville is middling, $0.044 a year per $1,000 against $0.030 for the typical town. Hazard risk gives Maugerville a grade of C−; its wildfire band pulls it down.
What stands out about Maugerville’s hazards
Four national sources, each read for Maugerville: earthquakes, radon, past fires and flood studies.

Maugerville grades C− for hazard risk
Two inputs always count for Maugerville, earthquakes and radon; the third, wildfire, counts only against a town.
How sure: The seismic figure is a long-run average from NRCan’s model, not a prediction. Small fires and grass fires are largely missing from the national burned-area record.
Fire reaches the land around Maugerville: 0% within 5 km, 5.7% within 25 km
Past fire around Maugerville’s homes, from the national burned-area record, with the fuel within 5 km.
The yearly burn rate around Maugerville is 0.23%, above 0.000% for the typical Canadian town but under the high band.
Since 1986 the nearest fire to Maugerville’s homes came within 8.5 km, never inside 5 km.
Within 5 km of Maugerville, 68% of the land is forest fuel; widen the ring to 25 km and it is 76%.

Towns with a flood study on file
Mapping in New Brunswick reaches 93% of towns, Maugerville included, beside 58% across Canada.

Flood studies don’t enter the grade; they are listed so you can open the official map for Maugerville.
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.”

More earthquake risk than most: only 32% of Canada’s 2,611 towns are above Maugerville.
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).

Test for radon in Maugerville: 17% of area homes were over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.
A higher share than most: 17% of tested homes around Maugerville, the typical Canadian town 6.6%. Maugerville doesn’t get its own radon tests figures; the ones here come from the Region 3 health region.
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 Maugerville had 7.1% over 600.

Get ready for what Maugerville faces
What to do about the hazards Maugerville 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?
- Check the address on the flood map.
- How close is the forest edge?
- Are flood and wildfire insured?
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 Maugerville’s.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Maugerville without grading them.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Maugerville’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- 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 Maugerville until then.
