| Abstract: | On the basis of the researches on the crust-upper mantle structure and crustal stress field in the Yangtze Gorges region and its vicinity,this paper analyzes the dynamic process and mechanism of preparation and generation of the moderately strong earthquakes in the region that is relatively stable.And in this paper some indicators for prediction of the moderately strong earthquakes in the region are given. |
