摘　　要：分析了通海地震的震源体过程、空间分布的时序特征及其对周边三角形构造块体内的地震活动可能造成的影响。探讨了通海地震迄今 30年来通海地震震源影响区内以该震开始而以武定地震结束的地震活动过程 ,指出未来几年内本区的地震活动可能会呈逐渐减弱的态势。The source process of Tonghai earthquake and the time sequence characteristics of spatial distribution and the possible influence to the seismicity for circumferential triangle block have been analyzed in this paper.Based on the analysis of time-space feature of focus body process of Tonghai earthquake and it’s dependent earthquakes, the seismicity of make a feature of beginning by Tonghai earthquake and ending by Wuding earthquake in Tonghai region as well as the focus influence area within 30 years have been discussed.It is Pointed out that the seismicity may be weakening gradually in the coming years in this region.
