强震复发间隔变异系数的一种计算方法
A method for computing the aperiodicity parameter of the strong earthquake recurrence interval
摘要
Abstract
Determining the aperiodicity parameter α (equivalent to the familiar coefficient of variation)is important for calculating the possibility of large earthquake occurrence.Considering the deviation between the estimate values ofαfrom small sample of earthquake sequences and the actual values of α,this paper presents a new method for computingα.Firstly,a large number of esti-mated values ofαfor small samples from earthquake sequences are calculated by maximum likelihood estimate method,and then the estimated values are stand-ardized and statistically analyzed.Finally,based on the 39 recurrent earthquake sequences,a general value ofα is given (α=0.34),and the physical meaning and application of the value are also discussed.关键词
