LANDSLIDES

In Australia, landslides have killed at least 74 people since 1842, and have damaged or destroyed over 200 buildings. As individuals, we can help protect ourselves and our property in the following ways:

BE AWARE!

Before occupying a home or building, check with council or neighbours for an area's history of landslides or potential instability. If in doubt consult a geotechnical specialist.

In steep areas, look for tell-tale signs of ground movement such as:

• disturbed or lumpy hill slopes;
• trees tilting (usually down-slope);
• water seepage;
• breaks in the ground;
• rocks or soil falling from road cuttings;
• cracks in walls;
• curb or fence line displacements; or
• cracks and subsidence in roads and paths.

Always take notice of signs giving warning of loose rocks and debris, and be very cautious of:

• tops and bases of cliffs or embankments;
• standing or sitting on rock ledges or overhangs;
• climbing, leaning, standing or sitting on a boulder; or
• digging or tunnelling into banks or under boulders.

IF A LANDSLIDE BEGINS

The start of a sudden 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 firmly and stay put until all land movement has ceased.

If outdoors, move quickly across the slope away from the likely path of the landslide. Try to keep clear of trees, powerlines and poles.

AFTER THE LANDSLIDE

I. Notify the appropriate authorities by dialling 000 if it is an emergency, or your local council if less urgent.

II. Watch for secondary hazards and assist victims as follows:

• Turn off electricity, gas, water. Do not light matches until you have checked for gas or fuel leaks.
• Check for and locate victims. If possible, apply first aid. Do not move the seriously injured unless they are in immediate danger from further slope movement, fire, etc.
• Check for broken water, sewerage or electrical mains.
• Keep telephone use to a minimum (to avoid network congestion).
• Check for cracks/damage, in roof, walls, chimneys and foundations.
• Evacuate if you feel that the building is unsafe.
• Listen to local radio and respond to warnings and advice on damage, service disruptions or recent activities.
• Keep streets as free as possible for emergency vehicles.
• Do not go sight-seeing or enter damaged buildings.
• Stay calm and help others if possible until help arrives.
• Be very cautious of removing material from the lower part of a landslide, or using machinery which creates vibrations near a landslide, as these activities may destabilise it.
