Abstract: A method was designed by taking the case of landslide hazards induced by the Wenchuan earthquake to study the correlation between parameters reflecting different ground motion characteristics and earthquake-induced landslide hazards. The results indicate that Arias intensity is the best parameter for disaster evaluation, which is more suitable for small region estimation. And the peak ground acceleration also behaves well in correlation analysis, but it is more suitable for evaluation of large area. The parameters, related with duration and frequency, can provide accessory information in analysis on mechanism of earthquake damage in concrete site. The vertical component plays an important role in evaluating earthquake-induced landslide hazards. The results have certain reference significance for selecting evaluation factors in studies related with earthquake-induced secondary hazards.
