对聊城——兰考地震带1970—1982年小震资料的分析表明,其小震的扩散—收缩图象和频度起伏似与华北强震有关;根据1937年菏泽7级地震震中区小震活动的空间分布情况,勾画出该次地震震源断层的产状轮廓;最后对该带近期地震危险性进行了讨论。
The analysis of small earthquakes from 1970 to 1982 in the Liaocheng-Lankao seismic zone shows that the diffusion-contraction images and frequency fluctuations of the small earthquakes may be related to the strong earthquakes in North China. According to the small earthquakes in the epicenter area of the Heze M7 MS7.0 earthquake The spatial distribution of the earthquake, delineating the origin profile of the focal fault of the earthquake; and finally discussing the recent seismic hazard of the belt.
