Studies on the earthquake sequences and the source mechanisms of the strong earthquakes show that Yunnan has more obvious subarea characteristics of earthquake type. Strike-slip seismic fault and mainshock-aftershock earthquake sequences are dominant in whole Yunnan area. Considering the ratio of non strike-slip faults and non mainshock-aftershock, Yunnan area can be divided into four subareas with...
The deep structure background of earth medium for strong earthquakes occurrence in Yunnan area is discussed in this paper, by using the results on the study of the velocity structure, electrical conductivity structure, geothermal structure in the crust and upper mantle in Yunnan area. The results show that the occurrence of strong earthquakes in Yunnan region is obviously related to the deep medium...
