【摘要】 叙述井分析了山西地震带地质构造特点和近期的中强地震及震群活动基本特征，在此基础上，与大同一阳高地震进行了分析对比，认为大同－阳高地震是山西地震带近期地震活动的继续，而山西地震带今后强震活动阶段的开始，其标志应是ＮＶＥ向新生代断陷内的中强地震活动，因此在分析和预估山西地震带今后地震发展趋势时，应密切注视这一地带的地震活动。更多还原

【Abstract】 The features of the geological structure of Shanxi seismic zone and the fundamental characters of the re-cent moderate earthquake or swarm activity are analyzed and described.According to such analysis,a compari-son withthe Datong-Yanggao earthquake is carried out.The results show that the Datong-Yanggao earth-quake is a continuation of the recent seismicity in Shanxi seismic zone,and the mark of the beginning of thestrong earThquake Elctivity in Shanxi seismic zone will be the moderate earthquake activity in the NNE-trend-ing Cenozoic downfaulted structures. The seismicity in the NNE-trending Cenozoic downfaulted structuresshould be noted in the analysis and forecast for the earthquake tendency of Shanxi seislnic zone.更多还原
