摘要
本文对中国大陆南北中轴地震带、天山地震带、山西地震带和燕山地震带等4条地震带内地震迁移现象进行了研究,证明了迁移的定向性,发现了迁移快波和慢波现象,求得迁移速度(V_M、V_m),提出了迁移的基础不是地震断裂的连续伸延,而是边界动力源脉动式推压引起的动力波的传播所决定的。
In this paper,based on the study of the earthquake migration of the four seismic belts in China mainland (South-North,Tianshan,Shanxi and Yanshan seismic belts),the directive property of migration was demonstrated and the phenomena of fast and slow waves in migration were found,velocities (Vm,Vm) which in migration were figured out.It is shown that the basis of earthquake migration is not the continuous connection and spreading of seismic fractures,which depends on the propagation of migration waves caused by the pulsating pushpressure force of the dynamic wave at boundary.
