1979年3月l5日,云南省普洱县内发生了一次6.8级地震,极震区位于该县的磨黑公社和孟先公社交界处。依据震中区正规穿斗木架房的破坏情况,震中烈度定为九度,极震区面积达18平方公里,六度线内的总面积为656平方公里,极震区几何中心位于N23°05′30″,E101°12′30″。国家地震局测定的微观震中是N23.1°,E101.1°。宏观方法确定的震源深度为5
March 15, 1979 In Pu’er County, Yunnan Province, a magnitude 6.8 earthquake occurred. The extremely seismic zone is located at the junction of Mohei Commune and Mengxian Commune in the county. According to the destruction of the formal wear-through wooden frame houses in the epicenter area, the intensity of the epicenter was set to nine degrees, the area of the epicenter reached 18 square kilometers, the total area within the hexagram line was 656 square kilometers, and the geometric center of the epicenter was located at N23 ° 05 ’30 “, E101 ° 12’30”. The microseismic epicenters measured by the State Seismological Bureau are N23.1 ° and E101.1 °. Macroscopic method to determine the focal depth of 5
