Little of the land around Studholm has burned: 0.9% within 25 km since 1986, or 0.02% a year. NRCan expects $0.029 of shaking damage a year per $1,000 of buildings in Studholm, near the typical $0.030. Radon is higher than usual: 11% of tested homes in the survey area topped the guideline, against 6.6% for the typical town. Hazard risk gives Studholm a grade of C+; its wildfire band pulls it down.

Studholm grades C+ for hazard risk
Earthquake risk and radon make Studholm’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #4 of 60 in New Brunswick and #1,831 of 2,589 Canadian towns.
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.

Towns with a flood study on file
Studholm 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 is shown here, never graded: a study says where a map exists, not how many of Studholm’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.”

Get ready for what Studholm faces
Practical steps for Studholm’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. Radon figures pool the survey’s home tests by area: postal areas once their boundaries arrive, the 2007 health region around Studholm until then.
- Wildfire counts one way. Burned land within 25 km of where people live, averaged over 1986–2025 and checked for fuel near homes, is the measure; it looks back, not ahead, and only ever counts against Studholm.
- Earthquakes are modelled. The earthquake figure is an expected loss, not a forecast, worked out by NRCan for each census subdivision, Studholm’s included.
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Studholm without grading them.
Questions about flooding and hazards in Studholm
How is Studholm’s Hazard risk Grade worked out?
Hazard risk gives Studholm C+, weighing earthquakes and radon and counting wildfire only against it.
Does Studholm flood?
A flood study covers Studholm on Canada’s Flood Map Inventory; open the owner’s map to check a street, since flood isn’t graded.
Is radon a problem in Studholm?
11% of the 101 homes Health Canada tested around Studholm topped the guideline; your own house needs its own test.
Is Studholm at risk of wildfire?
Not much by Canadian standards: Studholm’s band is low, with 0.9% of the land within 25 km burned since 1986 (last in 2006), so wildfire doesn’t change its grade.
How big is the earthquake risk in Studholm?
NRCan’s model expects shaking to cost buildings in Studholm $0.029 a year for every $1,000 of their value, on average over many years.
