摘要: 利用山东省内及其邻近海域(34°~39°N,114°~125°E),1996年1月至2009年5月的地震资料,通过最小二乘法及极大似然法对山东地区近年来的b值进行了求解及分析,给出了本区b值的计算结果,讨论了两种方法得到结果的差异,并对近年来b值时序变化的一些特点及其所反映的问题进行了讨论。Abstract: Based on small earthquakes data,this paper calculates and analyzes b-values from 1996 Jan.to 2009 May.in Shandong area using the least square method and maximum likelihood method and compares these two methods based on the results.Finally,we discuss the characteristics of b-values temporal variation in Shandong area and problems reflected by it.
