Deluge and landslides in the Illawarra, August 1998

While landslides caused significant damage to roads and some vehicles the major cause of damage in the region was from major flooding. The cause was 316mm of precipitation which fell in a 24 hour period among 537mm over 5 days.

Explanations of mass wastage

Chapter 3 clearly explains various forms of mass wastage using simple diagrams. It makes particular use of the Illawarra example, but also makes mention of the Thredbo disaster (July 1997) and the Gracetown (W.A) cliff collapse (September 1996).

Figure 3.2  A simplified geology of the Illawarra region This map, with other diagrams, is used to help explanation of the damage caused by the disaster. It is also the base map for a simulation game.

These are the diagrams used as part of the explanation in Figure 3.4 See the pdf file for an excerpt which gives more detail.
