Wildfire isn’t Murray River, Part 1’s worry: 0% of the land within 25 km burned since 1986 (0.000% a year). NRCan expects $0.020 of shaking damage a year per $1,000 of buildings in Murray River, Part 1, near the typical $0.030. Fewer homes than usual carry radon here, 3.5% over the guideline where the typical town has 6.6%. Murray River, Part 1 grades A for hazard risk; wildfire is low here, so it earns no credit.
What stands out about Murray River, Part 1’s hazards
Four national sources, each read for Murray River, Part 1: earthquakes, radon, past fires and flood studies.

Murray River, Part 1 grades A for hazard risk
Earthquake risk and radon make Murray River, Part 1’s grade; wildfire can only lower it, never raise it, and flood studies are listed but not scored.
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.

Towns with a flood study on file
Murray River, Part 1 is one of the 100% of towns on Prince Edward Island with a flood study on file; across Canada it is 58%.
NRCan Canada Flood Map Inventory: a study footprint touching the town’s boundary; towns of 2,500 people or more.
Flood studies don’t enter the grade; they are listed so you can open the official map for Murray River, Part 1.
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.”

Radon runs low around Murray River, Part 1: 3.5% of tested homes over the guideline
Health Canada’s survey of long-term home tests: the share above the 200 Bq/m³ guideline.
Murray River, Part 1’s area, at 3.5%, is below the 6.6% of the typical Canadian town, though any one home can still be high. Nobody publishes radon tests for Murray River, Part 1 alone, so this card uses the figure for the Prince Edward Island Health Region.
Tested homes over 200 Bq/m³

Get ready for what Murray River, Part 1 faces
Practical steps for Murray River, Part 1’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?
- Check the address on the flood map.
- Are flood and wildfire insured?
What this data can and can’t tell you
- Wildfire counts one way. The wildfire figure is the share of land within 25 km of Murray River, Part 1’s homes burned each year from 1986 to 2025, past fire rather than a forecast, and it can only lower Risk.
- Radon is a survey. Health Canada’s survey tested some 14,000 homes over three months; until postal-area boundaries are loaded, Murray River, Part 1 takes its 2007 health region’s share.
- Flood studies aren’t flood zones. The flood inventory points to maps; it is incomplete and not the official source, so ask the municipality about any street in Murray River, Part 1.
- 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 Murray River, Part 1’s.
