1986年8月12日18时45分,盐源县城西发生M_S=5.4级地震。西昌无线传输台网计算机最初定位于盐源县城西南(27°23′N;101°19′E)。盐源县城附近,房屋倒毁明显,人畜伤亡严重,被视为宏观震中所在。微观震中与宏观震相差12千米。地震的微观震中与宏观震中位置不一致,一个5.4级地震,两者相差5千米以上,属差别偏大,原因是微观震中定位不够精确。目前西昌无线传输台网对于M_L>2.5级的盐源地震的定
At 18:45 on August 12, 1986, an M_S = 5.4 earthquake occurred in the west of Yanyuan County. Xichang wireless transmission network computer initially located in Yanyuan county southwest (27 ° 23’N; 101 ° 19’E). Yanyuan County near the city, the apparent destruction of buildings, serious human and animal injury, is considered a macro epicenter. Microscopic epicenter and macro seismic difference of 12 km. The microseismic epicenter of the earthquake is inconsistent with the epicenter of the macro epicenter. A 5.4-magnitude earthquake, with a difference of more than 5 km, is a big disparity because of the inaccurate positioning of the microseismic epicenter. At present, Xichang wireless transmission network for M_L> 2.5 of the Yanyuan earthquake set
