| Abstract: | In this paper, the date of predecessors has been used to analyse relation between the structure of the crust-upper mantle and earthquake distribution in tectonic zone of western Sichuan and eastern Yunnan provinces. The results show that some characteristics of crust-upper mantle structure of tectonic zone of western Sichuan and eastern Yunnan provinces are similar to Qinghai-Xizang plateau. The earthquake active mainly distributes along the An'ning River fault zone and Xiaojiang fault zone. Its hypocenter in the field of Yongren, Dukou and Huili is more shallow than its circumference. |
