本文利用文献[1]、[2]和1)所采用的方法,对邢台地震后在山西地震带发生的震群和地震序列的U值、h值和k值进行了计算。结果表明,在山西地震带中,如果出现U≥0.6、K≥0.8或h>1的震群活动,在大华北东部都有中强地震发生。本文还讨论了山西震群与地震序列活动和大华北中强地震的关系。认为在1966—1976年大华北地震活动幕里,山西地震带的地震活动受其东部河北平原地震带的影响和控制。
In this paper, we use the methods [1], [2] and 1) to calculate the U, h and k values of the earthquake swarm and seismic series occurring in the Shanxi seismic belt after the Xingtai earthquake. The results show that in the Shanxi seismic zone, moderate earthquakes occur in the eastern part of North Da-hu-hua if any earthquake swarm with U≥0.6, K≥0.8 or h> 1 appears. The paper also discusses the relationship between the Shanxi earthquake swarm and seismic sequence activity and the mid-strong earthquake in North China. It is considered that the seismic activity of the Shanxi earthquake zone is affected and controlled by the seismic zone of Hebei plain in the east during the earthquake screen of North China in 1966-1976.
