Abstract: From the analysis of the distribution of strong earthquakes, the deep-seated crustal structures and the medium conditions, the authors of this paper attempt to divide the faults within the earth's crust into six groups and to estimate the depth and characteristics of seismo-pregnant layers. The motion of upper mantle materials, the faulting and seismicity are a common source-contemporaneous. The occurrence of strong earthquakes is directly controlled by the activities of both deeply penetrating faults and faults of basaltic layers.

摘要： 本文从强地震分布规律,地壳深部结构和介质条件出发,将地壳内部断裂划分为六个断裂组合,确定了孕震层的深度和条件。认为上地幔物质运动、断裂活动和地震三者是同生共源关系。超壳断裂和玄武质岩层断裂组合的活动,直接控制强震的发生。
