High radon around Eston: 20% of homes tested in the area exceed 200 Bq/m³
The national fire record shows next to nothing around Eston, 0% of the land within 25 km since 1986 (0.000% a year). Shaking is less of a worry than in most places, at $0.006 a year per $1,000 of building value ($0.030 typical). Hazard risk gives Eston a grade of B, from earthquakes and radon alone.
What stands out about Eston’s hazards
Four national sources, each read for Eston: earthquakes, radon, past fires and flood studies.
What Eston faces
Each hazard against its own yardstick; meters run from low to high on that yardstick.

Hazard risk in Eston: B
For Eston, 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. Small fires and grass fires are largely missing from the national burned-area record.
Little of the land around Eston has burned: 0% within 5 km, 0% within 25 km since 1986
Fires mapped since 1986 around where Eston’s residents live, and the fuel next to their homes.
Fire claims 0.000% of the land around Eston each year, a low band, with the typical Canadian town at 0.000%.
Only 0% of the land within 25 km of Eston is forest fuel, and 0% close in.

Burn rate a year, towns in Saskatchewan · highest of 105
Little or nothing burns around Eston in a typical year; 55 of the 105 towns in Saskatchewan share that, and La Loche leads at 1.94%.
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.
Only 7.5% of Canada’s 2,610 towns are above the low band, which holds 92%; Eston, at a rounded zero, is far from them.
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.

The flood map inventory lists nothing for Eston
Flood studies whose area touches Eston, from NRCan’s inventory, each linked to its owner.
No flood study on the national inventory covers Eston; ask the municipality, which is the authority for its flood maps.
Towns with a flood study on file
Eston has no flood study on file; only 55% of towns in Saskatchewan do, against 58% across Canada.
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 Eston’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.”
Little shaking expected in Eston: $0.006 a year per $1,000
NRCan’s seismic risk model: the damage shaking is expected to do to buildings each year, on average over many years.
At $0.006 per $1,000, Eston carries 0.2 times the typical Canadian town’s earthquake risk ($0.030): low.
Shaking damage a year per $1,000 of building value
About level with the typical town in Saskatchewan: Eston’s $0.006 against $0.006; Weyburn reaches $0.033.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Eston is in the lower part of Canada’s range for earthquake risk; 88% of the 2,611 towns are higher.
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 loss is to Eston’s buildings alone, from ground shaking; infrastructure and secondary hazards are left out.

Test for radon in Eston: 20% of area homes were over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline. · Measured across the Heartland RHA: radon tests
At 20% over the guideline, the area around Eston beats the typical Canadian town’s 6.6%.

More high tests than most: Eston sits in a band that only 22% of Canada’s 2,611 towns share, with 4.6% 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.
One home in Eston can be high while next door is low; a three-month test settles it.

Get ready for what Eston faces
Practical steps for Eston’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
- Radon is a survey. The radon share comes from about 14,000 long-term home tests in 2009–2011, pooled for now by the 2007 health region Eston sits in.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Eston’s figure is its subdivision’s.
- Flood studies aren’t flood zones. A study’s area can be a whole watershed or province, so being on the inventory says a map exists, not that a home in Eston floods.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Eston’s homes since 1986, a history of fire that may lower Risk but never raises it.
Questions about flooding and hazards in Eston
Is Eston at risk of wildfire?
Very little by the national record: Eston’s band is low, with 0% of the land within 25 km burned since 1986, so wildfire doesn’t change its grade.
Does Eston flood?
No study on Canada’s Flood Map Inventory covers Eston (0), which doesn’t mean it has never been mapped, so ask the municipality.
How is Eston’s Hazard risk Grade worked out?
Eston grades B for hazard risk, from earthquakes and radon, with wildfire counted only where it lowers the grade.
How big is the earthquake risk in Eston?
About $0.006 a year per $1,000 of building value, NRCan’s long-run expectation for Eston.
Is radon a problem in Eston?
20% of the 111 homes Health Canada tested around Eston topped the guideline; your own house needs its own test.
