摘　　要：本文以历史记载和仪器观测为依据,详细分析了山西带的地震活动资料,认为其具3个特点:①地震强度大频次高;②地震重复性强;③大震都发生在华北活跃期的后期。对目前山西带的地震危险性用应变能曲线进行了估计,认为当前山西存在发生7级地震的危险,以分区而言在38°N以南为M7.2左右,38°N以北则为M6.7左右。After analysing in detail the data of the earthquake activities in Shanxi belt in accordance with the historicalre-cords and the instrumental observations, the authors hol that there were three peculiarities: 1. the earthquake intensities were high; 2. the earthquake recurrence was frequent; 3. all the strong quakes occurred in the laterpart of the North -China active period. They estimated the hazardousness of earthquakes in Shanxi belt in the way of strain energy curve and hold that there exists a danger of earthquake about M7 in Shanxi at present , which will be about M7. 2 in the south of 38°N, and 6. 7 or so in the north of 38°N.
