【摘要】 在分析汶川地震发震构造和玉龙—龙门深断裂系的组成及活动特征基础上,利用构造类比的方法,筛选和对比研究了川滇地区与发生汶川MS8.0地震的龙门山断裂类似的地震构造。结果表明,NE向的小金河断裂具有MS≥7.0地震的发震能力,可能是潜在的大震危险区。更多还原

【Abstract】 We analyze the seismogenic structure of the Wenchuan MS8.0 earthquake and the composition and active characteristics of the Yulong-Longmen deep fault system.Based on the analysis we study the seismic structures in the Sichuan-Yunnan region similar to the Longmenshan fault,using structure analog method.The result indicates that the NE-direction Xiaojinhe fault is potential risk zone of large earthquake,on which MS≥7.0 earthquake possibly occurs.更多还原
