【摘要】 研究认为,地震是楔块运动引起的,楔块运动的主要动力来自于楔块内部的隐爆—均衡作用。"两堑夹一垒"是楔块运动系统的基本形式。研究发现,大洋中脊地震带、环太平洋地震带和大陆裂谷地震带(以郯庐断裂地震带为例)均位于"两堑夹一垒"楔块系统中,其中一垒的活动,即倒楔的运动与地震带紧密相关。更多还原

【Abstract】 Based on previous studies,we propose that the earthquake is mainly caused by the wedge block movement which are derived from the concealed explosive-equilibrium effect.Moreover,the fundamental mode of the wedge block movement is graben-horst structure.Our results highlight that the mid-ocean ridge seismic belt,circum-pacific seismic belt and continental rift seismic belt(Tanlu fault zone as an example)all lie in the graben-horst structure and the movement of the horst might be closely related to the seismic activity.更多还原
