Get prepared for a landslide

Landslides are the down-slope movement of rock or debris. As more homes are built onto steep slopes, landslides become a greater hazard for both people and buildings.

It’s important to take time to prepare and understand what to do before, during and after a major landslide.

Get prepared

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

Stay safe

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
