一、硅铝层密度反向差异引起的大陆地震用板块构造学说解释地震成因大多是成功的,这无疑符合“全球构造模式的一般格架”。作者也觉得,从观测结果上看,板块构造学说对地震成因的解释是令人信服的。但经过深入调查研究之后,对这种印象又变得模糊了。因为已查明的埋藏深的震源约为700公里,而大陆以下的软流圈边界深度可能为200公里,这是因为基底温度“已耗尽”的大洋 First, the inverse of the density of Si-Al layer caused by the continental earthquake plate tectonics theory explained that most of the causes of the success of the earthquake, which undoubtedly meet “general structure of the global grid ”. The author also believes that from the observation point of view, plate tectonics theory explained the cause of the earthquake is convincing. However, after thorough investigation and study, this impression has become blurred again. Because the deep buried hypocenter has been identified at about 700 km, the asthenosphere boundary below the mainland may be 200 km deep because of the ocean temperature of the base depleted ocean
