| 摘 要： | Studies on the earthquake sequences and the source mechanisms of the strong earthquakes show that Yunnan hasmore obvious subarea characteristics of earthquake type.Strike-slip seismic fault and mainshock-aftershockearthquake sequences are dominant in whole Yunnan area.Considering the ratio of non strike-slip faults and nonmainshock-aftershock,Yunnan area can be divided into four subareas with different characteristics,which arestrike-slip mainshock-aftershock in central Yunnan(A1),incline-slip swarm in northwestern Yunnan(A2),strike-slip double shocks in western Yunnan(B1)and quasi-strike-slip mainshock-aftershock in southwestern Yun-nan(B2),respectively.
