Mudslide Preparedness

What to do Before, During, and After a mudslide


  • Monitor local media, sign up for alerts.
  • Create and practice an evacuation plan for your family and your business.
  • Assemble and maintain an emergency preparedness kit.
  • Become familiar with the land around where you live and work so that you understand your risk in different situations.

Stay Alert:

  • Stay awake and observe your surroundings.
  • Listen for unusual sounds like trees cracking or boulders knocking together.
  • Watch for:
    • Leaning trees and utility poles
    • Water coming through the ground in new places
    • Widening cracks in the ground or street
    • Decks or patios that start to lean away from a house
    • Doors or windows that stick or jam for the first time
    • New cracks in tiles, bricks, or building foundations


  • Move away from the path of a landslide or debris flow as fast as you can.
  • If you can’t escape, curl into a tight ball and cover your head with your hands and arms.


  • Stay away from the slide area. There may be additional slides.
  • Do not touch dangling or loose wires, even with an object.
  • Call the Sheriff’s Dispatch at (707) 565-2121 to report any land movement.
