【摘要】 长春市尖山子—卡伦断层东段、南湖—桑家窝堡断层中段、伊通河断层北段均位于断层的交汇部位,并且这3个断层段直接位于长春市市区的下方,一旦发生地震将造成巨大的危害.通过经验关系估计了这3个相对危险段的震级上限,并通过统计概率性方法评价了这3个相对危险段的地震危险性.更多还原

【Abstract】 Changchun east part of Jianzi mountain to Kalun fault,middle part of south-lake to Sangjiawo castle fault,north part of Yitong river fault are located in the cross part of faults,and these parts of faults are located directly beneath the city of Changchun,once the earthquake will cause great harm.Through the relationship of experience,we estimated the upper limit of earthquake magnitude for these danger parts,and evaluated the three segment of the seismic risk by statistical probability method.更多还原
