Fire seldom reaches Rogersville: since 1986, 0.5% of the land within 25 km has burned (0.01% a year). Shaking is about as much of a worry in Rogersville as in most places, at $0.049 a year per $1,000 of building value ($0.030 typical). Rogersville grades D for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Rogersville’s hazards
For Rogersville, from NRCan’s seismic model, Health Canada’s radon survey, the national burned-area record and the flood map inventory.
What Rogersville faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Rogersville: D
For Rogersville, Risk will be the average of earthquakes and radon, with wildfire added only if it makes the average worse.
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.
Wildfire is rare near Rogersville: 0.5% of the land within 25 km burned since 1986, 0% within 5 km

The flood map inventory lists nothing for Rogersville
Flood studies whose area touches Rogersville, from NRCan’s inventory, each linked to its owner.
No flood study on the national inventory covers Rogersville; ask the municipality, which is the authority for its flood maps.
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 Rogersville.
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 Rogersville 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.”

Get ready for what Rogersville faces
Practical steps for Rogersville’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?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Flood studies aren’t flood zones. Flood studies cover areas of every size, which is why the page lists them for Rogersville without grading them.
- Earthquakes are modelled. Seismic risk is NRCan’s model of yearly building losses from shaking, averaged over many years and given for Rogersville’s census subdivision (a neighbourhood shows its city’s).
- Wildfire counts one way. For Rogersville, wildfire means how much nearby land burned in the past forty years, a one-way input that can pull Risk down and nothing more.
- 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 Rogersville until then.
Questions about flooding and hazards in Rogersville
How is Rogersville’s Hazard risk Grade worked out?
Hazard risk gives Rogersville D, weighing earthquakes and radon and counting wildfire only against it.
Is Rogersville at risk of wildfire?
Not much by Canadian standards: Rogersville’s band is low, with 0.5% of the land within 25 km burned since 1986 (last in 2020), so wildfire doesn’t change its grade.
Is radon a problem in Rogersville?
29% of the 200 homes Health Canada tested around Rogersville topped the guideline; your own house needs its own test.
How big is the earthquake risk in Rogersville?
Expected earthquake damage in Rogersville comes to $0.049 a year for each $1,000 that buildings are worth.
Does Rogersville flood?
No study on Canada’s Flood Map Inventory covers Rogersville (0), which doesn’t mean it has never been mapped, so ask the municipality.
