按内波假说的观点，讨论了典型板内地震即中国大陆地震的成因机制，认为造成地壳厚度分化的内波运动依靠地壳厚度差异中蕴藏的重力位能，推动地壳物质运动形成各种类型的板内地震。研究了全球地震活动的纬度分布特点以及地震活动与潮汐作用及大陆分布的联系，指出：外动力地质作用强烈的大陆因剥蚀、搬运和沉积以及负载重分布，使大陆地区始终达不到重力均衡，成为地壳运动的活动区，因而陆壳“地震能量发射强度”曲线具有类似于潮汐剪应力纬度分布的两极衰减、南北对称的特性。文中还探讨了深震及和达—贝尼奥夫带的成因，克服了用俯冲板块解释这一现象的困难。
According to the hypothesis of internal wave, the formation mechanism of a typical intra-plate earthquake, ie, the earthquake in China, is discussed. It is considered that the intra-wave motion that causes the crustal thickness differentiation depends on the gravitational potential energy contained in the difference in crustal thickness and promotes the movement of crustal material to form various types of Intra-plate earthquake. The latitude distribution of the earthquakes in the world and the relationship between the seismic activity and the tidal forces and the distribution in the continent are studied. It is pointed out that due to erosion, transport and sedimentation and load redistribution, the continents can not reach the balance of gravity , Which becomes the active area of the crustal movement. Therefore, the “seismic energy emission intensity” curve of the continental crust has the characteristics of dipolar attenuation and north-south symmetry similar to the latitudinal distribution of tidal shear stress. The paper also discusses the causes of the deep earthquakes and the Da-Benioff belt and overcomes the difficulty of interpreting this phenomenon with the subducting slab.
