一、引言包括地球在内的任何星体的扁率、自转速度和星体密度都具有内在统一性。地球经过长期的旋转过程,地壳外形和它的内部结构,为了适应固有的重量和离心力联合作用,慢慢形成稳定的“平衡椭球体”。研究表明,在其自转速度基本不变的情况下。地球内部任何部位的密度产生突然变化,会导致地块失稳而产生运动,并由此造成地壳中垂直运动和水平运动的发生,甚至会诱发地震。 I. INTRODUCTION The flattening, rotation speed, and astral density of any body, including the Earth, are inherently uniform. Earth’s long-term rotation process, the crust shape and its internal structure, in order to adapt to the inherent weight and centrifugal force combined action, and slowly form a stable “balance ellipsoid.” The research shows that under the condition that the rotation speed is basically the same. Sudden changes in the density of any part of the Earth’s interior can cause the landslide to move and cause vertical and horizontal movements in the earth’s crust and even induce earthquakes.
