| 摘 要： | 本文主要以重力和热力的相互矛盾作为指导思想,从能量转换和物质运移的角度试论我国地震的成因和机制,以及大洋板块运动对大陆地震的影响。指出驱动力在时间和空间上是可以转换的,震源机制既随力源而变化,也受介质的岩性和结构所控制。所谓水平和垂直运动是一种相对概念,可以互相转化

DISCUSSION ON DRIVING FORCES AND MECHANISMS OF EARTHQUAKES IN CHINA FROM THE VIEWPOINT OF EARTH'S CRUST DYNAMICS |
| |
| Abstract: | This paper considers mainly the contradiction between the gravitational force and heat energy as a guidence dealing with the occurring of earthquakes in China and their mechanisms from the angle of both energy transformation and material transportation. Although earth rotation, gravity and heat energy are major driving forces to produce tectonic activities and seismicities, but the first one is just regarded as a long-term acting force for slow motion of its interior materials, the second acts a |
