Landslides

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 beforeduring 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.

What to do During a 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.

What to do After a Landslide

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.
