摘要
按时间的顺序,将2001年昆仑山口西8.1级地震前的地球物理场转折、中强地震图像演化、周缘动力环境变化、震时的同震变化、震后的地震活动响应与前兆场的调整、5级以上地震的持续平静等过程衔接起来,划分出了该次巨大地震震前、震时、震后的5个不同演化阶段.
According to time sequence,the pregnancy and evolution process of west to Kunlun Mountain Pass M8.1 earthquake in 2001 is divided into 5 stages,based on linking up the data from the transition of geophysical fields, the evolution of seismicity patterns of moderate strong earthquakes and the change of dynamic environment around mainland of China before the event;the simultaneous change of some observatory terms;the seismicity correspondence,the adjustion of precursor field and the continual quiescence of earthquake (MS≥5) after the event.
