A landslide is the movement of rock and soil down a slope. Landslides can range in size from a single boulder in a rock fall to a very large avalanche of debris with huge quantities of rock and soil that can be spread across many kilometres.


Heavy rain, floods or earthquake shaking can cause a landslide. Human activity, such as removal of trees and vegetation, steep roadside cuttings or leaking water pipes can also cause landslides.

Before a landslide

Getting ready before a landslide will help reduce damage to your home and business and help you survive.

  • Find out from your council if there have been landslides in your area before and where they might occur again

  • Check for signs that the ground may be moving. These signs include:

    • Sticking doors and window frames

    • Gaps where frames are not fitting properly

    • Decks and verandas moving or tilting away from the rest of the house

    • New cracks or bulges on the ground, road or footpath

    • Leaning trees, retaining walls or fences

    • Water springs, seeps or waterlogged ground in areas that are not usually wet


If you think a landslide is about to happen

You will need to know how to respond immediately

  • Evacuate and take your Getaway Kit with you

  • Contact Emergency Services on 111

  • Warn neighbours who might be affected


After a landslide

  • Do not return to a site that has been affected by a landslide until it has been properly inspected

  • Take photographs and notes for insurance purposes
