CHARACTERISTICS OF EARTHQUAKE ACTIVE INTERVAL IN HEBEI AND ITS NEIGHBORING AREA
-
摘要: 介绍了地震活动时间间隔的研究历史和定义,对河北省及邻近地区地震活动时间间隔分布的统计点图、间隔一频次统计图进行了分析,分析时结合不同的震级层次、不同的统计时段(长短不同)、不同的活动水平以及地震活动的丛集与孤立。统计结果显示地震活动时间间隔对数-频次统计结果与G-L关系式的统计结果类似,地震活动时间间隔对数一频次也呈指数分布。最后对预测中存在的不足进行了一些简单说明。Abstract: the history and definition to study earthquake active interval are introduced, and the statistical graph for the distribution of the intervals as well as statistical graph of interval-frequency in Hebei and its neighboring area are analyzed.In analysis we considered the following factors:magnitude level, length of statistical interval, active level and cluster grouping and isolation in occurrence.The results show that the logarithm of interval-frequency assumed exponential distribution, so did the G-L relation.
