摘要
通过对1700年以来川滇地区6.7级以上强震活动的分析,发现川滇菱形块体是川滇地区主要的强震活动区域,强震活动关联度较高,主要表现为:(1)川滇菱形块体为川滇地区地震活动关联的主体;(2)滇东与川西地区的强震活动存在一定的呼应关系;(3)川滇菱形块体将可能进入新一轮强震活跃期;(4)川滇菱形块体东边界地震活动的有序迁移可能是对块体运动的响应。
The activities of the strong earthquakes with Ms ≥ 6.7 in the Sichuan and Yunnan regions since 1700 has been studied. The result indicates that Sichuan-Yunnan Rhombic Block is the main active region of strong earthquakes and the correlation of strong earthquake activities is high in the block. It is mainly shown as follows ： （ 1 ） Sichuan-Yunnan Rhombic Block is the main correlative region of strong earthquake activities in Sichuan and Yunnan; （2） there exists some relation between the strong earthquake activities in East Yunnan and West Sichuan; （3） a new round of strong earthquake activity will begin in Sichuan-Yunnan Rhombic Block; （4） the orderly transfer of the strong earthquake activity along the eastern border of the Sichuan-Yunnan Rhombic Block may respond to the movement of the block.
