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. Additionally, in areas that have been severely burned by wildfires, the risk of landslides and debris flow may exist for two years or more.

It’s important to take time to prepare and understand what to do beforeduring and after a major landslide. To learn about how to propect your propert, download the PreparedBC Landslide Information Guide.

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,  or call 9-1-1.

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.

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.

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.
  • Follow official local government channels for emergency information, as well as trusted local news sources.
  • Watch for flooding, which may occur after a landslide or debris flow.
