摘要： 将变差函数分析方法引入地震时间相关性的研究,并以华北地区的强震和松潘地震的前震和余震序列为例对地震的时间相关性进行了分析,在得到华北地区强震相关性规律的同时还定量估算了其周期,并对比了松潘前震和余震序列时间相关性的差异。

关键词: 结构分析, 变差函数, 相关性, 华北强震

Abstract: The simi-variogramanalysis is introduced to study the seismicrelativity in this paper. While applying this method to the typical seismicregions and sequences, the authors detect unexpectedly not only theperiodicity of earthquakes in North China, but also the distinct difference of relativity between foreshocks and after shocks of Songpan earthquake.

Key words: Structural analysis, Simi-variogram, temporal relativity, Strong earthquakes in North China
