【Abstract】 This paper interprets the geological setting of the earthquake origin structure in the three-river structural zone according to the characteristics of geotectonics, crust structure and regional seismic fault belt. The features of time-space distribution of seismism in the three-river fault zone and the law of earthquake origin area are analyzed and studied. And the cause of frequent seismism in the complicated seismic geological environment of Yunnan is discussed.更多还原
