摘要: 根据深部探测资料,发现岩石圈电性结构与深部流体分布迁移有密切的关系,深部流体与地震有密切的关系。在深部探测和高温高压流体性质研究的基础上,提出了以深部流体为重要条件的岩体势-动能转换地震成因说,简称地震流体成因说。最后,探讨了此假说在地震测报工作中的应用及其依据。

Abstract: Based on geophysical prospecting, especially on magnetotelluric sounding (MT),a close relation among the conductivity layers in the crust and upper mantle, the deep-seated fluids in the crust and the earthquake distribution in China's continent has been found. The conductive mechanisms of the crustal conductive layer (CCL) and the supercritical aqueous fluid are discussed. A model called the potential-kinetic energy transformation is presented. In this model, the crustal deep-seated fluid evolution is considered to play the most important role in the seismogenic process. Finally the application of this model to earthquake prediction is introduced in this paper.
