本文研究华北地区的地震图象和地震迁移,范围为30°—42°N,105°—125°E。根据流变学的基本观点提出该区域内地震分布在正交网络内,大震预计发生在网络的节点部位。这一设想为该地区的震中分布所证实。将破裂方向和主应力方向与断层面解对比,它们的一致性进一步证实了这一设想。据此,本文提出预报未来可能发生地震震中位置。
This paper studies seismic images and seismic migration in North China, ranging from 30 ° -42 ° N and 105 ° -125 ° E. According to the basic rheological point of view, it is proposed that the earthquakes in this area are distributed in an orthogonal network, and the large earthquakes are expected to occur at the nodes of the network. This idea is confirmed by the epicenter distribution in the area. The rupture direction and principal stress direction are compared with the fault plane solution, and their consistency further confirms this assumption. Accordingly, this paper proposes to forecast the possible epicenter location of the earthquake in the future.
