浅析太原盆地小震活动的时间特征

Brief Analysis for Time Feature of Small Earthquake Activity in Taiyuan Basin

通过对山西地震台网近年来记录到的太原地区小震活动的分布情况、地震频度及能量释放强度的分析，得出该盆地地震活动在时间分布上具有丛集性的结论。统计分析认为该区发震概率最大时间段为每年的１月、２月、６月、１１月份。

Through the analysis for the distribution situation,the seismic frequency and the energy release of the small earthquake activity in Taiyuan region recorded by Shanxi seismological network in recent years,we obtained the conclusion that the seismicity in the basin has cluster feature of time distribution The statistical analysis suggested that the time interval of the most earthquake occurrence probability is annual January, February , June and November
