Abstract:In this paper,the history and progress of study on stopping phase are reviewed systematically,and the physical mechanism of stopping phases in the source rupture process is discussed.The master-event analysis method and the synthetic seismogram method including stopping phase are discussed in detail.By using the master-event analysis method,the actual data of the Tangshan earthquake are processed,and we get the spatial-temporal picture of the source rupture process during the Tangshan earthquake,meanwhile,the synthetic seismograms including stopping events are calculated.The results show that with taking into account of stopping events of rupture process,the Pwave observed seismograms can be fitted better,the possibility is further confirmed that there existed two stopping events during the source rupture process of the Tangshan earthquake.Finally,the source environment of the Tangshan earthquake and the abdication of adjustment element are also discussed.
