Abstract: On 12 May 2008, a catastrophic earthquake with surface wave magnitude of 8.0 struck the Sichuan Province of China. Tens of thousand of landslides were triggered by this earthquake over a broad area. 48007 landslides were interpreted from aerial photographs and multi-source remote sensing imageries, verified by field check. A spatial database, including landslides and associated controlling parameters which may have influence on the occurrence of landslides, was developed and analyzed using geographical information system(GIS) technology. The correlations of landslide distribution with controlling parameters, including faults, lithology, elevation, slope angle, slope aspect, drainages and roads are firstly analyzed, and landslide area-ratio was calculated for each group of the above parameters. An analytical hierarchy process(AHP) was then applied to determine the significance of controlling parameters in triggering the landslides. The resulting susceptibility map showed five classes of landslide susceptibility, i.e. extremely high, high, moderate, low, and extremely low. The area with extremely high and high susceptibility accounts for about 8211 km2, 16.9% of the study area. This indicates that the result is reasonable in 60.5% of the landslides occurred in high or extremely high susceptibility region. (24 refs.)
