Rapid landslide susceptibility mapping. (ADD008).


Landslides are a common natural hazard and have a major impact on life and property. Conventional geotechnical methods of producing regional landslide hazard maps can be slow and costly. Remote sensing and spatial analysis using a GIS provide potentially useful tools for the rapid preparation of such maps. Pilot studies were carried out in Papua New Guinea and Fiji using satellite images, aerial photographs and existing geoscientific information. Models of landslide susceptibility were created by correlating the various information themes with the known distribution of landslides, interpreted from the imagery, and by combining the information. A refined method, using a probability based weights-of-evidence analysis, was applied to further test areas in Jamaica and Slovakia. The resulting maps display good correspondence with the known distribution showing that the technique can map landslide susceptibility in a range of vulnerable environments.
