Wildfire is rare near Liverpool: 0.1% of the land within 25 km has burned since 1986, a burn rate of 0.004% a year. Seismic risk in Liverpool sits near the middle: $0.024 of expected damage per $1,000 of buildings a year, the typical town $0.030. Hazard risk gives Liverpool a grade of A−; its wildfire band pulls it down.
What stands out about Liverpool’s hazards
Four national sources, each read for Liverpool: earthquakes, radon, past fires and flood studies.
What Liverpool faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Liverpool: A−
Seismic risk and radon set Liverpool’s grade, wildfire can drag it down, and flood mapping stays out of it.
Its place: #30 of 88 in Nova Scotia and #875 of 2,589 Canadian towns.
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.
Wildfire is rare near Liverpool: 0.1% of the land within 25 km burned since 1986, 0.1% within 5 km
Fires mapped since 1986 around where Liverpool’s residents live, and the fuel next to their homes.
Low by Canadian standards: 0.004% of the land a year around Liverpool, 0.000% for the typical Canadian town.
Forest fuel is spread evenly around Liverpool: 90% within 5 km, 91% within 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 Nova Scotia · highest of 90
In the lower half in Nova Scotia: Liverpool at 0.004% a year, 52nd of 90, far from Barrington’s 0.46%.
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.
The low band takes in 92% of Canada’s 2,610 towns, Liverpool among them, though its rate is above zero; 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.

No flood study is listed for Liverpool
Flood studies whose area touches Liverpool, from NRCan’s inventory, each linked to its owner.
An empty entry for Liverpool on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
Missing from a well-mapped province: Liverpool has no study, where 88% of towns in Nova Scotia 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.
The grade leaves flood out, since a study area says nothing about how many of Liverpool’s homes are at risk.
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.”
Ordinary seismic risk in Liverpool: $0.024 per $1,000 of buildings a year
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
Nothing unusual about Liverpool’s ground: $0.024 against a typical $0.030, 0.8 times.
Shaking damage a year per $1,000 of building value
At $0.024, Liverpool is above the typical town in Nova Scotia ($0.018); Clare has the most at $0.034.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Liverpool sits mid-range among Canada’s 2,611 towns: 54% expect more shaking damage.
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).
The model counts damage to Liverpool’s buildings and their occupants from shaking only: not liquefaction, landslides, tsunami or fires after a quake.

Some radon around Liverpool: 6.2% of area homes over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Area-wide: radon tests, counted over the Zone 1 health region
Liverpool’s area, at 6.2%, is close to the 6.6% of the typical Canadian town.
Tested homes over 200 Bq/m³
Over 600 Bq/m³
Fewer homes top the guideline around Liverpool (6.2%) than in the typical town in Nova Scotia (13%), yet 2.1% went over 600.

Radon tops the guideline in a modest share of homes around Liverpool, a band holding 37% of Canada’s 2,611 towns; 26% rank 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.
The share describes the area, not a house: in Liverpool as anywhere, test to be sure.

Get ready for what Liverpool faces
Practical steps for Liverpool’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
- Wildfire counts one way. Wildfire is read from the national burned-area record around Liverpool’s homes since 1986, a history of fire that may lower Risk but never raises it.
- 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 Liverpool.
- Radon is a survey. About 14,000 homes were tested across Canada in 2009–2011, and the share over the guideline for Liverpool is its health region’s, the survey’s design unit.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Liverpool’s figure is its subdivision’s.
Questions about flooding and hazards in Liverpool
How is Liverpool’s Hazard risk Grade worked out?
Hazard risk gives Liverpool A−, weighing earthquakes and radon and counting wildfire only against it.
Is radon a problem in Liverpool?
6.2% of the 97 homes Health Canada tested around Liverpool topped the guideline; your own house needs its own test.
Is Liverpool at risk of wildfire?
Not much by Canadian standards: Liverpool’s band is low, with 0.1% of the land within 25 km burned since 1986 (last in 2023), so wildfire doesn’t change its grade.
How big is the earthquake risk in Liverpool?
About $0.024 a year per $1,000 of building value, NRCan’s long-run expectation for Liverpool.
Does Liverpool flood?
No study on Canada’s Flood Map Inventory covers Liverpool (0), which doesn’t mean it has never been mapped, so ask the municipality.
