Landslide

Most landslide risks will have been planned for by councils or government departments. However, there are other types of landslides that could pose a threat.

BEFORE

  • Learn about the risk of landslides in your area and consult available landslide mapping/zoning.
  • Be aware that landslide insurance is not available anywhere in Australia.
  • Comply with planning controls in relation to slope stability.
  • Make sure that any construction work you do does not increase the landslide risk. You can do this by having a landslide risk assessment undertaken by a suitably qualified practitioner.
  • Learn how to recognise initial signs of landslide – these may include:
    • Movement of structures such as decks and patios;
    • Sticking doors and windows, indicating shifted frames and jambs;
    • Tilting or cracking of concrete floors and foundations;
    • Offset fences or retaining walls;
    • Breaks in services, such as water pipes and sewers;
    • Long, continuous cracks (often curved) opening in the ground; and
    • Ground subsiding in some parts and possibly rising in others.

 

DURING

If you find yourself in an area of identified landslide hazard, be aware that during storms, sudden impact landslides may occur.

  • Alert proper officials if a landslide movement has occurred or is expected to happen.
  • Alert neighbours, especially those downslope, if they may also be affected by the landslide.
  • If initial signs of a landslide are developing rapidly, then leave the area.

 

AFTER

  • Stay clear of unstable areas, which can continue to expand in all directions.
  • Expect ongoing movement of a slide or continuing falls or flows of material.
  • If you’ve been affected by the landslide, turn off water, gas and electricity if affected by the landslide.
  • Ensure others are aware of the danger, for example, rock fall onto a road.
