Landslides and mudflows occur in all 50 states, often triggered by heavy rain, wildfires or earthquakes.

How to prepare your home

  • Learn whether your area has a history of landslides or debris flows.
  • Watch for warning signs: new cracks, tilting trees, doors that suddenly stick.
  • Plant ground cover on slopes and build retaining walls where appropriate.
  • Be especially alert after wildfires — burned slopes shed water fast.
  • During intense storms, stay awake and ready to evacuate if in a risk zone.
