摘要

祁连山构造带地震迁移活动研究表明,存在不同震级层次的地震迁移现象:①大震顺构造带迁移由东而西震级衰减;②中强地震沿构造带东、中、西段交替发生;③横构造带地震跳迁会影响顺构造带地震的有序迁移;④祁连山中东段—东段存在发生破坏性地震的背景。
In this paper,the study of earthquake migration in the Qilianshan structural zone shows that there are different kinds of earthquake migration in different magnitude of earthquake.① The large earthquake migrates it′s way from east to west along the Qilianshan structural zone,and the magnitude of earthquake decreases.② The moderate strong earthquake occurs alternately in the east,west and middle of Qilianshan structural zone.③ The order of earthquake migration along the structural zone is affected by the earthquake migration crossing the Qilianshan structural zone.④ The destructive earthquake will occur in the central to eastern part of Qilianshan structural zone probably.
