一九八二年二月二十五日,江西龙南县发生一次5.0级地震,根据现场调查和地震台网观测资料,取得这次地震的震源参数及序列特征。 一、主震震源参数 发震时刻:1982年2月25日 08—39—10 震中位置:北纬24°44,4′ 东径114°48.0′位于龙南县南亨——临江公社之间。 震源深度:16公里 震级(Ms):5.0 震源位置的确定,采用包围震中的龙川,焊州、会昌、韶关、新丰江等台站数据,经过震相校正,分别用和达法、高桥法、石川法在五十万分之一地形图上交切,取综合结果。
On February 25, 1982, a magnitude 5.0 earthquake occurred in Longnan County, Jiangxi Province. According to the on-site survey and the observation data of the seismic network, the source parameters and sequence features of the earthquake were obtained. First, the main shock source parameters Seismogenic time: February 25, 1982 08-39-10 epicenter location: latitude 24 ° 44,4 ’east 114 ° 48.0’ is located in Nanheng Hengnan - Linjiang commune. Depth of focal point: 16 km Magnitude (Ms): 5.0 The location of the focal point is determined by station data of Longchuan, Jiazhou, Huichang, Shaoguan and Xinfengjiang surrounding the epicenter, Bridge method, Ishikawa law on the topographic map of one hundred thousand cross, take comprehensive results.
