摘    要:分析了广西北海地区地震活动的特征,认为北海地区历史地震和现代地震活动水平较高。通过对1970-2004年北海地区b值和缺震时间进行扫描分析,认为b值高值异常和缺震低值异常可能是该区中强地震的前兆异常。

关 键 词:地震活动特征  地震前兆  异常  北海地区

Abstract:Based on the analysis on the characteristic of seismicity in Beihai region of Guangxi,it is thought that the levels of historical and modern seismicities in Beihai region are both high in some degree.Through the time scanning analysis on b-value and earthquake deficiency in Beihai region from 1970 to 2004,it is thought that high b-value and low earthquake deficiency may be the precursory anomaly of medium-strong earthquake in the research region.
Keywords:Characteristic of seismicity  Earthquake precursor  Anomaly  Beihai region
