| 摘 要： | 通过对汶川8.0级地震与地球自转的关系的分析,提出了一个新的地震成因观点,认为地震的根本原因在于地球自转速率的变化.地球岩石圈由大小不同、质量不同的块体组成.比如,大洋块体薄、质量轻,大陆块体厚、质量重.地球自转速率变化时,就会造成这些块体运动的差异性.这种差异运动可能使块体之间发生"追尾"撞击或摩擦,从而引起地震.地震能量来自于块体间撞击或摩擦时损失的动能. |
| 关 键 词： | 地球自转 汶川地震 地震成因 |

| Abstract: | A new viewpoint about the cause of earthquakes is proposed in this paper after investigation into the relationship between the earth rotation and the M8.0 earthquake on May 12th,2008 in Wenchuan,Sichuan Province.The fundamental cause of earthquakes could lie in the variation in velocity of the earth rotation.The lithosphere of the earth consists of plates with different volumes and masses.For instance,the oceanic plate is thinner and lighter,and the continental plate thicker and weightier.The variation in v... |
