【摘要】 从断层间相互作用产生的同震库仑应力改变入手,提出了断层间相互作用的触震与缓震效应,探讨了断层间的相互作用对断层活动性、断层未来地震潜势及余震活动分布图像的影响。从断层间相互作用的角度分析了大陆强震准周期丛集复发行为的可能的物理机制。认为断层间的相互作用具有重大的地震地质意义,在进行断层活动习性和断层地震危险性定量评价及余震分布图像预测时,应该充分考虑断层间相互作用的影响。更多还原

【Abstract】 Based on the concept of the change in co-seismic Coulomb stress resulting from the interaction of faults, the earthquake trigging and delaying effects of fault interaction are proposed in this paper. The influences of fault interaction on the activity and seismic potential of faults as well as the spatial distributed image of aftershocks are analyzed. From the viewpoint of fault interaction, the possible physical mechanism of the quasi-periodically clustering recurrence behavior of continental strong earthquakes is discussed. It is concluded that the fault interaction is very significant for both seismology and geology. In the quantitative assessment of fault activity and seismic potential and in the prediction of aftershock distribution, the influence of fault interaction should not be ignored.更多还原
