摘要:
根据eQuake-RC网站及相关文献,建立了383个地震全局参数的数据集,与二十多年中3篇参考文献先后发表的震源全局参数及其定标律统计结果比较,讨论了定标律的稳定性。虽然数据量大大增加,尤其是高震级数据增加更显著,震级范围扩大,不同年代的全局参数与矩震级域数据点的分布大多重叠,新补充的数据往往分布在以往数据分布的延伸方向上。区分两类地震、三种破裂类型、五(三)个震级段统计全局参数定标律,与3篇参考文献的结果比较,期望值两两相对差别的特征相近,统计标准差有所减小,说明随数据增加全局参数定标律结果变化不大,总体趋于稳定。分4组比较、分析数据分布的区域特征,没有发现系统性差别,说明全球数据是可以一起统计的。板内地震和俯冲带地震分组的结果表明,震级范围不同,高震级段数据分布存在明显差异,宜分开统计。
Abstract:
Based on the eQuake-RC website and related literatures, this study builds a dataset of global parameters from 383 earthquakes, makes a comparison with the global source parameters and the corresponding scaling laws obtained by statistics in three references published in the past two decades, and discusses the stability of the scaling laws. The amount of data, especially those with large magnitudes, increases significantly and has a wider magnitude range. The distributions of the global parameter of different ages with magnitude are mostly overlapped, and the new additions to the dataset are generally distributed along the trending direction of the past distributions. The scaling laws of the global parameters are obtained with distinguishing two kinds of earthquakes, for three rupture types and five (or three) magnitude intervals. The comparison with three references shows that the characteristics of relative differences of expected values between two datasets are similar and the standard deviation decreases. This indicates that with the accumulation of the source data, the scaling laws of global parameters change slightly, and the trend is becoming increasingly stable. The comparative analysis of the regional characteristics of four groups of data distributions shows no systematic differences, and thus the worldwide data can be statistically analyzed together. The results between the intraplate and the subduction zone earthquakes show that the magnitude range is different, and data with large magnitudes have quite different distribution, and it is better to analyzed separately.
