摘要
quot;EnDivSummary">Based on the susceptibility evaluation model of the co-seismic geohazards in the Wenchuan earthquake,this paper adopts 6 influencing factors including the distance from the seismic fault,topographic slope,lithology,the distance from river system,elevation and PGA to make a fast prediction for the spatial distribution of geohazards triggered by the "4·20" Lushan earthquake.The preliminary results suggest that the zones with high susceptibility of co-seismic geohzards are mainly distributed over the rural areas of some counties and cities including Lushan,Baoxing,Tianquan,Ya’an,Yingjing and Qionglai in Sichuan Province,and concentrate in the areas near the seismic fault,that is,the front Longmenshan fault,including Dachuan town,Baosheng village and Shuangshi town of Lushan County,Lingguan town of Baoxing County,and Xiaohe town of Tianquan County.
