What to Do When... There's a Landslide

Landslides occur in all 50 states and cause $1-2 billion in damage annually. The most common trigger is water. When heavy rains occur, the particles in the earth are loosened and may start to flow, producing a landslide. Other common causes include earthquakes, wildfires and volcanoes.

Below we've compiled lists of landslide warning signs and what to do during and after a landslide.

Landslide Warning Signs

Landslides can happen quickly, often with little notice. The best way to prepare is to look for the following warning signs:

  • New cracks in parking lots or sidewalks
  • Tilting or cracking of concrete floors/foundations
  • Leaning telephone poles or trees
  • Saturated ground in areas that are not normally wet
  • Unusual bulges in the ground

During a Landslide

If your business encounters a landslide, follow these safety tips:

  • Contact local police and fire departments to notify them of a landslide.
  • Listen to local radio/news for updates on debris flow.
  • If evacuation is a safe possibility, evacuate all employees; if not, alert employees to curl up and protect their heads.
  • Listen for any sounds that may indicate moving debris, such as trees cracking or boulders knocking against each other.
  • Be extremely cautious if driving. Watch the road for cracked pavement and be aware of falling rocks.

After a Landslide

  • Anticipate flooding, which may occur after a landslide or debris flow.
  • Alert your local utility service of any broken utility/power lines near your building.
  • Stay away from the landslide area. Move employees to an alternate work environment to continue business operations.
