以一系列断陷盆地为主体的断陷盆地带是山西的地震构造带和未来地震的主要危险区。叙述了盆地的新生性、第四纪活动度、盆地的剪切运动和拉张运动特征及盆地的现代地壳运动特征和现代地壳应力场特征，分析了盆地的特征、地震震级—频度模式、古地震复发间隔和地震活动周期、山西历史强震前的地震活动图像及盆地的各项特征和地震活动的关系。在此基础上得到，２００５年前山西基本上不具备发生Ｍ≥７地震的危险性，其发震概率在０．０５～０．１０间，指出发震概率最大的是临汾盆地和忻定盆地
The faulted basin belonged to a series of fault-depression basins is the seismic zone in Shanxi and the main danger zone for future earthquakes. The characteristics of the basin, such as the characteristics of the basin, magnitude-frequency of the earthquake, frequency of the earthquakes, RELATIONSHIP BETWEEN EVALUATION CHARACTERISTICS AND SEISMIC ACTIVITY OF ANCIENT SEISMIC RECURRENT INTERVAL AND SEISMIC ACTIVE CYCLE, SEISMICITY IMAGES BEFORE SHANXI MAJOR SEISMOGRAMMIC AND BASIN. Based on this, it is concluded that before 2005, Shanxi Province did not have the danger of M≥7 earthquakes basically, and the probability of its occurrence was between 0.05 and 0.10. It is pointed out that the most probable earthquakes are the Linfen and Xinding basins
