At 16:00 on December 28, 1982, an M_s = 5.3 earthquake occurred in Yongping County, Yunnan Province. According to the Kunming-Taiwan test, the epicenter is latitude 25o30 ’north and longitude 99o23’ east. After the earthquake, Yunnan Seismological Bureau immediately sent inspection team went to the scene. The seismic damage survey results show that the earthquake epicenter intensity of Ⅵ degree, Ⅵ isosceles north-south narrow spindle into the spindle; 12 km long axis, extending north-west 18 degrees; the shortest axis at the widest 3.4 km, the most Narrow 1.3 km, an average of 2.3 km; epicenter area of 27.6 square kilometers.
