Abstract: The September 30, 2009, Padang earthquake has induced huge landslide in Padang Pariaman district, West Sumatera, Indonesia. The goal of this paper is to assess the landslide susceptibility of Pariaman, using the weight of evidence statistical method. The method is based on the decision of which state is more likely to occur grounded on the presence or absence of a predictive variable and the occurrence of an event (e. g. , landslide) within a pixel. This method can be used without requiring geotechnical, groundwater or failure depth data. However, the other factors to influence landslide occurrence, such as slope, curvature, peak ground acceleration, geological condition, lineaments/faults distance of landslide to the rivers and, land use can be known. This is quite impressive, based on AUC The highest factor controlling the landslide is lineament, than following with lithology, peak ground acceleration, slope and land use. Weights calculated individually for those themes were added to produce a probability estimate of the area. The predictive of the map was tested on the basis of 35 % sample of landslides that were not used in the modeling process (test data). Analytical result verified by using test data of landslide shows AUC prediction rate is 0.849 and AUC success rate using all landslide data is 0.894 with difference 0.045. This condition to the allowed tolerance of 15 %. This is showing good model of landslide susceptibility. The obtained landslide susceptibility map and landslide inventory data base can be used for landslide hazard prevention and mitigation, and proper planning for land use in the future.
