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.

The cost of landslide is underestimated in Australia because the impact and loss associated with these events are not readily reported or captured. There is no reliable source of data which highlights landslide cost to communities and explains who currently pays for the impacts and associated costs. The aim of this document is to investigate and analyse landslide costs within a Local Government Area (LGA) in order to highlight the varied landslide associated costs met by the local government, state traffic and rail authorities and the public. It is anticipated this may assist in developing a baseline awareness of the range of landslide costs that are experienced at a local level in Australia. Local government authorities across Australia are required to manage and mitigate landslide hazards. The Illawarra region of New South Wales (NSW) is one example of an area in Australia continuously affected by slope failure, often resulting in damage to property or infrastructure as well as occasional injuries and fatalities. Landslide losses are described for the region of Wollongong in NSW using a series of case studies to highlight the different types of landslide cost met by different parties, the variations in the landslide types that occur and the different cost components arising from them. This approach was chosen due to variations across the quality, availability and consistency of data. It was found that many generic natural hazard cost models are inappropriate for determining landslide costs because of the differences in the types of landslide movement and damage. Further work is recommended to develop a cost data model suitable for capturing consistent landslide cost data. Better quantification of landslide cost is essential to allow comparisons to be made with other natural hazard events at appropriate levels. This may allow for more informed policy development and decision making across all levels.

This report provides regional information on hazard and risks posed by landslides to communities within the southeast Queensland area. Research is based on the mapping of landslides that resulted from the January 1974 rainfall event. It firstly identifies areas of potential landslide using two methodologies and then undertakes a quantitative assessment of landslide hazard and risk.

The cost of landslide is underestimated in Australia because their impact and loss are not readily reported or captured. There is no reliable source of data which highlights landslide cost to communities and explains who currently pays for the hazard and how much costs are. The aim of this document is to investigate and analyse landslide costs within a Local Government Area (LGA) in order to highlight the varied landslide associated costs met by the local government, state traffic and rail authorities and the public. It is anticipated this may assist in developing a baseline awareness of the range of landslide costs that are experienced at a local level in Australia. Initial estimates in this study indicate that cumulative costs associated with some landslide sites are well beyond the budget capacity of a local government to manage. Furthermore, unplanned remediation works can significantly disrupt the budget for planned mitigation works over a number of years. Landslide costs also continue to be absorbed directly by individual property owners as well as by infrastructure authorities and local governments. This is a marked distinction from how disaster costs which arise from other natural hazard events, such as flood, bushfire, cyclone and earthquake are absorbed at a local level. It was found that many generic natural hazard cost models are inappropriate for determining landslide costs because of the differences in the types of landslide movement and damage. Further work is recommended to develop a cost data model suitable for capturing consistent landslide cost data. Better quantification of landslide cost is essential to allow for comparisons to be made with other natural hazard events at appropriate levels. This may allow for more informed policy development and decision making across all levels.

This set of Australian landslide images illustrates the causes of landslides, both large and small, and other earth movements. A set of 15 slides with explanatory text; includes images of Thredbo, NSW, Sorrento Vic., Gracetown WA and Tasmania.

On the 30th September 2009 a magnitude 7.6 earthquake struck West Sumatra in the Padang and Pariaman regions. It caused widespread damage to buildings and resulted and an estimated 1,117 fatalities. Thankfully the event was not accompanied by a tsunami that could have had additional devastating impacts and a greatly increased mortality. Under its mandate the AIFDR responded to the earthquake event with the objective of deriving an understanding of the factors that had contributed to outcome. It supported a team of Indonesian and international engineers and scientists who collected and analysed damage information that could subsequently be used for future disaster risk reduction in West Sumatra and Indonesia more broadly. The activity was jointly led by the Centre for Disaster Mitigation at the Institut Teknologi Bandung (ITB) and Geoscience Australia. This report provides a background to the region, describes the nature of the earthquake and its impacts, details the survey activity and outlines the significant outcomes that has come from it. Importantly, it makes several recommendations to assist in the regional reconstruction after the event and to guide future development in the Padang region and Indonesia more generally.

The evolution of the Australian Landslide Database (ALD) was driven by the need for a nationally consistent system of data collection in order to develop a sound knowledge base on landslide hazard and inform landslide mitigation strategies. The use of 'networked service-oriented interoperability' to connect disparate landslide inventories into a single 'virtual' national database, promotes a culture of working together and sharing data to ensure landslide information is easily accessible and discoverable to those who need it.
