Travel Distances of Earthquake-induced Landslides
Over 30,000 landslides occurred during the Wenchuan earthquake on 12 May 2008 in China. The casualty caused by these earthquake-induced landslides was approximately one quarter of the total casualty of this earthquake. The travel distance is a key parameter that measures the vulnerability to landslides. An appropriate model is required to evaluate the possible travel distances of earthquake-induced landslides so that planners can better select safe sites in earthquake-prone areas in the future. This paper describes a study on the travel distances of earthquake-induced landslides. We focus on 160 landslide cases in which relevant geometric data is available. Considering the substantial variations of the lithology and topographic conditions, multi-variable regression models are established for rock slides and soil slides separately. A comparison between the travel distances of rain-induced landslides and the landslides triggered by the Wenchuan earthquake is also conducted.
