Abstract
An analysis defining potential landslide hazard over a 650 km2 region of southeast Queensland, Australia is presented. Attributes of geology, slope, aspect, morphology, curvature and vegetation were de-termined for the study area at a 5 m pixel resolution within a GIS environment. A decision tree analysis was employed to gather attribute values from landslides mapped following the 25-28th January 1974 rainfall event and to use this data as training for the prediction of further areas of potential instability. Application of a deci-sion tree analysis creates rulesets of the most ?informative? attributes that define areas of landslide potential as well as attributes that define areas of little landslide potential. The rulesets were then imported back into a GIS environment where they were located spatially. Field checking indicates that the predictions for further areas of potential landslide activity within this region are intuitively sound. It is envisaged that this research will prove beneficial to managers and land use planners involved in regional assessments.
