长期以来,地震学方法一直是地球物理学家用于探测地球内部奧秘的主要方法。正是这个方法,曾经为二十年前兴起的地球科学的一场革命——板块构造学说的形成和确立提供过有力的观测证据由地震观测得出的全球地震活动性图象为我们勾画出了岩石层板块的边界,向我们展示了岩石层板块在深部减的证据;震源机制解的系统分析则向显我们示了作用于板块边界上的力方向和性质。
Seismological methods have long been the primary method used by geophysicists to probe the mysteries of Earth’s interior. It is this method that has provided powerful observational evidence for the formation and establishment of plate tectonics, a revolution in geoscience that took place two decades ago. Global seismicity images derived from seismic observations delineate The boundary of the lithosphere shows us the evidence of the deep decrease of the lithostratigraphy; the systematic analysis of focal mechanism solutions shows us the direction and the nature of the force acting on the boundary of the plate.
