where do landslides occur
Landslides occur regularly in a variety of landscapes across every Australian State and Territory. These landscapes are commonly characterised by cliffs, steep slopes of colluvium deposits or gentle slopes of unstable geology and slopes which have been subjected to periods of prolonged or intense rainfall.
In many cases, heavy rains set off landslides. However, in many cases landslides may also occur in unpredictable was, such as the timing of a rockfall after a spring thaw. Sometime deep-seated slumps or mudflows will not move until days or weeks have passed after a storm.
