AB: Analysis on earthquake-induced landslide triggering factors susceptibility is an important step to every slope safety estimation method. Based on GIS, the susceptibility of earthquake-induced landslide triggering factors of Longling Earthquake in1976 is analyzed by means of the slope certainty factors (CF). The factors contributing the landslide occurrence include lithology, faults£¬earthquake intensity, epicenter distance, slope angle£¬slope aspect, elevation£¬river etc£®The results show that different factor contribution to landslide is due to its value, and the most numerical intervals of each factor which are inclined to landslides are determined. This work is the basement for further study of earthquake-induced landslide susceptibility analysis.
