【摘要】 在了解长春地区地震相关资料和地质背景的基础上,调查研究区域断裂构造特征,并说明了F1~F10断层的长度、产状、类型及特征、活动年代等,比较得出对长春地区影响较大的4条活动断层,即F1、F2、F4、F6断层。对古近纪以来构造运动和有历史记录的区域地震情况进行了综合分析,结合构造断裂和地震时空分布特征,推测潜在震源区,并按照区域地貌特征分别给出了有利于城市建设的建议。更多还原

【Abstract】 Based on the available preference about earthquakes and geological background of Changchun area,research the character of geological structure and seismic activity,show the length,shape,style and activity age of the faults F1～F10,choose destructive faults F1、F2、F4、F6.Analyzed the tectonic movement since Paleogene and seismic activity in the region,combining the tectonic faults and characteristics of spatial and temporal distribution of earthquake,confer the potential seismic region,and according to the physiognomy to give advise about city building.更多还原
