摘要

本文通过《中国历史强震目录》、《中国近代地震目录》、《中国地震台报告》、《中国地震详目》及部分地方台网测定的地震目录,初步分析了华南地区1000a以来中强地震(5.0≤M≤6?)的原地重复性,并从时、空、强三方面对地震原地重复特点做了统计分析。分析认为华南地区中强地震的发生具有较高的原地重复率,在时间、强度上都具有一定的规律性。这些规律的探讨对该地区地震区划及工程场地地震安全性评价具有一定的参考价值。

Abstract

The statistical analysis is performed to study the spatial and temporal recurrence characteristics of moderate-strong earthquakes (5.0≤M≤6?) of South China in 1000 a. The earthquake records used in this study are from “Historical strong earthquake catalogue of China”, “The recent modern earthquake catalogue of China”, “China seismic station report,” “Detailed earthquakes catalogue of China”, and the partial earthquake catalogue from the local network in south China. The results suggest that the moderate-strong earthquakes occurred in situ in South China have relatively higher recurring rates with some regularities in spatial and temporal domain. The regularities may be helpful to seismic zonation and safety assessment of earthquake engineering in the region.
