GIS-based landslide susceptibility mapping using analytical hierarchy process in Wenchuan

Abstract

This paper aims at presenting and testing a simple semi quantitative approach for mapping regional landslide susceptibility in the Wenchuan earthquake area, as shown in Fig. 1, using few key parameters and analytic hierarchy process (AHP) method. AHP is an expert-based method, which combines the numerical value with the intuitive experience. The validation of the method shows that the method is suitable for the landslide susceptibility assessment in the Wenchuan earthquake area.
