地震学——关于地震的科学——可分为两个基本方面:对地震波传播规律和影响的研究以及对地震本质的研究。第一方面研究正在成功地发展着,并且在测定地球内部结构方面取得了巨大成就,特别是能够帮助确定寻找有用矿物的方向。在研究地震本质方面,情况则相当差。我们对导致地震发生的过程本身迄今仍不太清楚,其原因在于:地震学的传统理论基础——连续介质力学
Seismology - the science of earthquakes - can be divided into two basic aspects: the study of the laws and effects of seismic wave propagation and the study of the nature of earthquakes. The first is that research is progressing successfully and great achievements have been made in the determination of the internal structure of the Earth, in particular to help determine where to find useful minerals. In studying the nature of the earthquake, the situation is rather poor. The reason why the process of causing earthquakes themselves is still not clear enough so far is that the traditional theoretical basis of seismology - continuum mechanics
