The Lushan M_S6.1 earthquake occurred in the southern section of the Longmenshan fault zone on June 1,2022,which is located in the north of the residual area of the Lushan M_S7.0 earthquake in 2013,causing a relatively serious secondary geological disaster. Based on field investigation and remote sensing interpretation,this paper analyzes the spatial distribution of seismic geological hazards and their relationship with topographic slope,lithology and faults. Combined with the spatial distribution of main aftershocks and the results of focal mechanism solution,the relationship between seismogenic structures and secondary geological hazards is discussed preliminarily. The results show that:①The field investigation suggests that the seismic and geological disasters mainly occur in the Donghe river valley area,in the types of small and medium-sized rock landslides mostly. The slope is dominantly in the range of 30°～50°,and the lithology is mainly diorite and granite. ②The seismogenic structure of this earthquake is different from that of Lushan earthquake in 2013,which is related to Shuangshi-Dachuan fault. ③The seismogenic structure of this earthquake is a blind reverse thrust fault inclined to SE,and the geological disaster mainly developed in the upper wall of the fault,and mainly distributed in the area between the branch fault of Wulong-Yanjing fault and Shuangshi-Dachuan fault along the Donghe river valley.
