东亚大陆由众多的大陆块和岛弧、海沟沉积物、海底冲积扇和海山等拼凑所组成。印度大陆的碰撞也不外乎是一系列集聚与加积的过程。现在东亚、特别是中国内陆发生了许多地震。要理解这种活动构成成因和变形方式,就必须探讨东亚的形成过程。 East Asia consists of numerous continental blocks and island arcs, trench sediments, alluvial fans and seamounts. The collision in India is nothing more than a series of processes of concentration and accumulation. Many earthquakes have now taken place in East Asia, especially in the interior of China. To understand the cause of formation and deformation of such activities, the formation of East Asia must be explored.
