Landslides involve the movement of large amounts of either earth, rock, sand or mud, or any combination of these.

Landslides are infrequent in Logan, however, they are a reality. They can be caused by a major event such as earthquakes, but also by soil saturation from rainfall or seepage, or construction activity.

Before occupying a home or building, check with Council or neighbours for the area's history of landslides or potential instability.

In steep areas, tell-tale signs for ground movement include:

  • disturbed or lumpy hill slopes
  • trees tilting
  • water seepage
  • breaks in the ground
  • cracks in walls
  • cracks and subsidence in roads and paths


The start of a landslide may be marked by a loud sound such as a crack, an explosion, a roar or a rumble.

  • If indoors, shelter at the least-affected end (down slope) of the building under a strong table or bench (if possible, use a mattress for extra protection)
  • Hold on and stay put until all land movement has ceased
  • If outdoors, move quickly across the slope away from the likely path of the landslide, trying to keep clear of trees, powerlines and poles.


  • Notify the authorities by dialling 000 if it is an emergency, or Council on 07 3412 3412 if less urgent
  • Watch for other landslides
  • Turn off electricity, gas and water
  • Check for broken water, sewerage, gas or electrical mains
  • Check for cracks/damage in roof, walls, chimneys and foundations
  • Evacuate if you feel the building is unsafe
  • Listen to local radio stations, and/or TV stations if power is available, and respond to official warnings and advice on damage and service disruptions
  • Be very cautious about removing materials from the lower part of the landslide, or using machinery that creates vibrations, as these activities may cause further movement.
