摘要
作者根据 80年代以来山西遥测地震台网所记录到的 11次 3级以上地震序列的初动资料 ,研究了各个地震序列的初动特征。认识到 ,不同类型的地震序列其震源机制的一致性特征不同。初动矛盾符号比的减小与增大 。
Based on the initial motion data of the earthquake sequence with M L≥3\^0 of 11 times recored by the Telemetered Seismic Network of Shanxi since 1980s, the initial motion characteristics of each earthquake sequence had been studied.It is recognized that the concerted characteristics of the earthquake focal mechanism of earthquake sequence for various types are different.The decrease and increase of the initial motion contraction rate might be regarded as a judge index for the next large earthquake after the earthquake sequence.
