Fire seldom reaches Gibsons: since 1986, 0.2% of the land within 25 km has burned (0.005% a year). In Health Canada’s survey, just 2.5% of homes tested in the area exceeded 200 Bq/m³ (6.6% typical). Gibsons grades C+ for hazard risk, with wildfire counted against it.
What stands out about Gibsons’s hazards
Four national sources, each read for Gibsons: earthquakes, radon, past fires and flood studies.

Gibsons grades C+ for hazard risk
Earthquake risk and radon make Gibsons’ grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
Its place: #208 of 254 in British Columbia and #1,845 of 2,589 Canadian towns.
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.
Wildfire is rare near Gibsons: 0.2% of the land within 25 km burned since 1986, 0% within 5 km
Past fire around Gibsons’ homes, from the national burned-area record, with the fuel within 5 km.
Around Gibsons fire takes 0.005% of the land in a typical year, the typical Canadian town 0.000%, which is low.
Fire has stayed at least 9.4 km from Gibsons’ homes since 1986.
Forest fuel covers 64% of the land close to Gibsons and 83% across 25 km.

The flood map inventory lists nothing for Gibsons
What Canada’s Flood Map Inventory lists for Gibsons: who studied flooding and where to see their maps.
An empty entry for Gibsons on the inventory isn’t proof of safety; ask locally for flood maps.
Towns with a flood study on file
Mapping in British Columbia reaches 76% of towns, beside 58% across Canada, but not Gibsons.
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 Gibsons’ 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.”
High seismic risk in Gibsons: $0.48 per $1,000 of buildings a year
Expected yearly building losses from earthquakes, from Natural Resources Canada’s model.
Roughly 16.1 times the typical $0.030: Gibsons’ $0.48 marks real seismic exposure.
Shaking damage a year per $1,000 of building value
Above the middle in British Columbia: Gibsons’ $0.48 against a median of $0.36, with Duncan highest at $1.33.
NRCan seismic risk model (2022): mean yearly building loss per $1,000 of value; medians of towns of 2,500 people or more.
Gibsons is in the top tenth of Canada’s 2,611 towns for earthquake risk; 1.4% rank 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).
Roads, pipes and bridges aren’t in Gibsons’ figure, nor landslides or tsunami: it is buildings and shaking.

Radon runs low around Gibsons: 2.5% of tested homes over the guideline
Long-term radon tests in homes across the survey area, against Health Canada’s guideline.

63% of Canada’s 2,611 towns have a higher share of homes over 200 Bq/m³ than Gibsons’ band, which holds 37%.
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.
Basements, soil and how a house is sealed decide its radon, so in Gibsons only a test can say.

Get ready for what Gibsons faces
Practical steps for Gibsons’ 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.
- Drop, cover and hold on.
- Strap the water heater down.
- Keep 72 hours of supplies.
- Has it had a radon test?
- Ask the municipality for flood maps.
- Are flood and wildfire insured?
- Is earthquake cover included?
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 Gibsons without grading them.
- Wildfire counts one way. Wildfire is read from the national burned-area record around Gibsons’ homes since 1986, a history of fire that may lower Risk but never raises it.
- 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 Gibsons until then.
- Earthquakes are modelled. NRCan models what earthquakes would cost buildings each year on average, subdivision by subdivision; Gibsons’ figure is its subdivision’s.
Questions about flooding and hazards in Gibsons
Does Gibsons flood?
The inventory has 0 studies for Gibsons, and an empty list isn’t a clean bill: the municipality holds any flood maps.
Is radon a problem in Gibsons?
The area’s survey found 2.5% of 81 tested homes above Health Canada’s guideline, so a three-month test is worth doing in Gibsons.
How big is the earthquake risk in Gibsons?
NRCan’s model expects shaking to cost buildings in Gibsons $0.48 a year for every $1,000 of their value, on average over many years.
How is Gibsons’s Hazard risk Grade worked out?
Hazard risk gives Gibsons C+, weighing earthquakes and radon and counting wildfire only against it.
Is Gibsons at risk of wildfire?
Some, but Gibsons’ low band (0.2% of nearby land burned since 1986, latest 2019) is short of the level that counts.
