论述了大同盆地中强地震活动的时空特点及与华北北部中强地震活动之间的关系,发现在时间进程中,大同盆地的中强地震活动受华北强震活动周期的制约;在空间分布上与华北北部中强地震成丛活动密切相关。得出1989年大同—阳高6.1级地震后,与大同盆地相邻的忻定盆地、延怀盆地发生612级左右地震的危险性增大的结论
Discusses the spatio-temporal characteristics of moderate-strong seismic activity in the Datong Basin and their relationship with the moderate-strong seismic activity in the northern part of North China. It is found that the moderate-strong seismic activity in the Datong Basin is restricted by the active periods of the strong earthquakes in North China during the time course. In the spatial distribution It is closely related to the clumping of moderate-strong earthquakes in North China. After the Datong-Yanggao MS6.1 earthquake in 1989, the danger of the 612-magnitude or so earthquake in the Xinding and adjacent areas in the Datong Basin increased.
