1982年11月16日,在湖南省宜章县、临武县和广东省连县交界处发生的3.5级地震,是南岭纬向构造带上继当年2月25日江西省龙南5级地震后又一次引人注目的小震活动,并且在全国地震趋势会商会上为人们所提及。因此,对这次小震活动全面回顾一下,很有必要。 一、地震基本参数的测定 据收集整理的湖南省及江西、广西、广东三省区共24个地震台资料,利用和达曲线,取其中直线相关最好的15个台资料(最大相关系数r=0.9995),求得发震时刻T_0为19时16分45.3秒,波速比ν=1.634(比基值偏低6％)。用和达法和石川法初定震中为北纬25°08′56.4″,
On November 16, 1982, the magnitude 3.5 earthquake that occurred in the junction of Yizhang County, Linwu County and Lian County of Guangdong Province was the zonal structural belt of Nanling. On the afternoon of February 25, the Longnan M5.5 earthquake in Jiangxi Province After another striking small earthquake activity, and in the National Earthquake Trend Chamber of Commerce for people to mention. Therefore, a comprehensive review of this small earthquake activity is necessary. First, the determination of the basic parameters of the earthquake We collected a total of 24 seismological stations in Hunan, Jiangxi, Guangxi and Guangdong provinces and regions. Using the sum-up curve, we took the 15 stations with the best linear correlation (the maximum correlation coefficient was r = 0.9995). The onset time T_0 was 19:16:45:35 and the velocity ratio ν = 1.634 (6% lower than the base value). The initial epicenter with the Tathagata method and Ishikawa method is 25 ° 08’56.4 "north latitude,
