What stands out about Rogersville’s hazards
Four national sources, each read for Rogersville: earthquakes, radon, past fires and flood studies.

Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Rogersville: D
The grade weighs Rogersville’s seismic risk and radon equally, and wildfire is one-sided: a high band counts against a town, a low one earns nothing.
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.
Few fires near Rogersville: 0% within 5 km, 0.7% within 25 km
Fires mapped since 1986 around where Rogersville’s residents live, and the fuel next to their homes.
Low: the land around Rogersville burns at 0.02% a year, where the typical Canadian town sees 0.000%.
The 5 km ring around Rogersville’s homes is clear of burns since 1986, the nearest 15 km out.
Near or far, forest fuel covers a similar share around Rogersville: 91% within 5 km and 93% within 25 km.

No flood study is listed for Rogersville
Flood studies whose area touches Rogersville, from NRCan’s inventory, each linked to its owner.
Nationally, Rogersville has no listed flood study; the municipality is the place to ask.
Towns with a flood study on file
Missing from a well-mapped province: Rogersville has no study, where 93% of towns in New Brunswick have one against 58% nationally.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood mapping is shown for Rogersville 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.”

Get ready for what Rogersville faces
What to do about the hazards Rogersville faces, and what to ask before you buy.
- 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
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Rogersville is its health region’s, the survey’s design unit.
- 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 Rogersville’s.
- Flood studies aren’t flood zones. NRCan’s inventory says where flood mapping exists, not where water goes; the map’s owner is the authority for Rogersville.
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Rogersville’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
