Landslides are the down-slope movement of rock or debris. As residential developments expand onto steep slopes, landslides are becoming a greater hazard for both people and homes.
It’s important to take time to prepare and understand what to do before, during and after a major landslide. Download the PreparedBC: Landslide Information for Homeowners and Home Buyers guide to learn about protecting your home and property.
What to do Before a Landslide
The best way to prepare for a landslide is to be aware of changes that could signal one. To report suspected landslide indicators, call the 24-hour provincial toll-free number at 1-800-663-3456, contact 9-1-1 or call your local fire, police or public works department.
Landslide or debris flow indicators may include:
- Sudden changes in stream flow.
- Rapid changes or pulses in stream flow (e.g. changes in volume) or pulses of sediment (e.g. changes from clear to murky water).
- Abnormally dirty water.
- Accumulation of large logs or debris.
- Rapid accumulation of sediment or bed-load along a flat section of a creek channel.
- Tension cracks near the top of a slope.
- Falling rocks or boulders or flowing or sliding soil. This may precede a much larger landslide.
Leave the area immediately if you observe the following:
- A faint rumbling sound that increases in volume.
- Unusual sounds, such as trees cracking or boulders knocking together.
- If you are caught in a landslide with no option to evacuate, curl in a tight ball and protect your head and neck.
Take these initial steps after a landslide to ensure your safety:
- When you are safe, report the situation by calling 9-1-1.
- Stay away from the slide area as there could be subsequent slides.
- Listen to local radio or television stations for the latest emergency information.
- Watch for flooding, which may occur after a landslide or debris flow.
