The distribution of landslides in the twelve counties where Longmenshan faults pass through was investigated before and after Wenchuan earthquake.Then,the logistic regressive model was utilized to assess the landslidesusceptibility before and after the earthquake.Based on the susceptibility mapping and transformation matrix,thesusceptibilities showed a significant spatial variation before and after the earthquake.The high susceptible zones forlandslides were located along river valleys before the earthquake,while primarily along the Longmenshanfaults after the earthquake.The extreme high susceptible zones did not change.The areas with low susceptibility near the Longmenshan faults turned into high susceptibility level after the earthquake.
