- Abstract:
- The Sichuan-Yunnan area is composed of Sichuan-Qinghai block and Sichuan-Yunnan rhombic block. The rupture zones at the eastern and western boundaries of the Sichuan-Qinghai block and the eastern boundary of the Sichuan-Yunnan block are main tectonic zones in eastern Yunnan. We analyze the spatio-temporal distribution features of strong earthquake activity in the Sichuan-Yunnan area according to regional tectonics and background stress field,and further study the evolution rule of the strong earthquake activities on the three rupture tectonic zones,and the interaction and relation between them. Based on above analyses we discuss the influence of the Wenchuan earthquake on the strong earthquake activity in Yunnan,especially on those on the major rupture zones in eastern Yunnan,and analyze the possibility of strong shock in this area quantitatively and scientifically according to the dynamic changes of frequency of small shocks,b value,and seismic risk D value in eastern Yunnan.
