摘要
As an integral part of seismological research,focal mechanism plays an important role in not only interpreting earthquake preparation,but also describing the nature of seismic source and rupture process to some extent.Rapid and automatic inversion system can speed up inversion and provides more source information,which potentially increases the efficiency of rescue operations,seismic regime analysis and aftershock prediction.In this paper,we elaborate on the inversion method for focal mechanism,and also summarize the construction ideas and the current research progress of automatic inversion system.Meanwhile,such system can provide technical ideas for the construction of automatic inversion system.
