摘要
本文对吉林省伊通-舒兰断裂带发生的地震,我国南北地震带南段安宁河-滇东地震带的中强地震发震时间间隔进行统计分析,把每两个发震时间相减得到地震的时间间隔Xi序列,由Xi序列求出概率密度函数f(x)或其分布函数F(x).经统计分析,都服从正态分布,在一定的概率意义下,可提出地震活动趋势意见.并预报下次地震区间。
Shocks occurred in Yitong-Shulan faulted zone and moderate earthquakes occurred in Anninghe-Diandong Seismic belt of south section of North-South earthquake zone have been compared and analyzed by means of statistic method in this paper.
