本文应用国际地质对比计划组织对海平面研究结果,把海平面升降与板块构造运动联系起来进行分析研究,提出地球内外动力系统支配的板块运动规律,即第四纪200万年期间板块运动的平均速率公式为:U_h=(A+n·k)Td。由此可得到板块运动的跳跃周期,并可用以解释全球地震活动的周期。 In this paper, the International Geological Comparison Program organizes the results of sea level research, and analyzes the correlation between the sea level rise and the tectonic movement of the plate. Proposes the law of the plate movement dominated by the dynamical systems inside and outside the Earth, that is, the average movement of the plate during the 2 million years of Quaternary The rate formula is: U_h = (A + n · k) Td. From this we can get the jumping period of plate movement and can explain the period of global seismic activity.
