据全球地震的分布及其与地质构造的关系,编制了全球地震构造纲要图。全球地震构造基本上可分为三大系统;(1)以海壳与陆壳聚合俯冲带为背景的环太平洋地震构造系;(2)以陆壳内分区的和分带的构造变动为背景的大陆地震构造系;(3)以海壳内引张与转换断层组合带为背景的大洋脊地震构造系。三者的地震活动、构造形态和变动方式各有特点,
According to the distribution of earthquakes in the world and its relationship with the geological structure, the global seismic structure map has been compiled. The earthquakes in the world can basically be divided into three major systems: (1) the Central Pacific seismotectonic system based on the polymerized subduction zone of sea shells and continental crusts; and (2) the tectonic movement of zoning and zonation in the continental crust ; (3) the oceanic ridge seismic tectonic system based on the combination of extension and inversion fault in the sea shell. The three seismic activities, structural patterns and changes have their own characteristics,
