Abstract:Pre-earthquake prediction and rapid post-earthquake assessment of earthquake-triggered landslide hazards have become one of the important ways for mitigating secondary seismic hazards. In this paper,we use a simplified Newmark model to predict the potential earthquake-triggered landslide areas in the Wentai earthquake zone by setting the earthquake(MS5.0),using basic data such as regional geological maps and DEM,with the consideration of the amplification effect of topography on ground shaking. The study shows that under both dry and saturated environments,the high-risk areas for earthquake-triggered landslides in the study area are mainly located within 15km of the set epicentre,and their distribution is the same as the distribution of rock-soil mass in the area in a critical stable state. The reservoir dam site and reservoir body in the area are not affected by potential earthquake-triggered landslides,while the villages of Qianqiumen,Tuojia,Gaoxi,Dushan,Nanxiang,Baokeng,Longqian and Xinchang,as well as roads at all classes in the focus area,are vulnerable to earthquake-triggered landslides. The risk preparedness capabilities of disaster-bearing bodies in the focus area should be enhanced to minimise the threat to life and property in the area caused by potential earthquake-triggered landslides.
