| 摘 要： | 利用地震学分析预报方法程式指南及“八五”“九五”攻关研究成果中有关震群性质的分析方法,对2005年2月五原震群做了详细研究,并根据该震群序列本身的统计参数及震源与介质的某些特征进行综合分析。结果认为,该次震群对应于临河盆地的前兆意义不明显,它可能是阴山隆起区2005年7月蒙古3次中强地震孕育过程中区域应力场增强的背景下,临河断陷带应力自调整的结果。

| Abstract: | In this paper,we make a detailed study on the Wuyuan earthquake swarm in February 2005 using the prediction method of the seismological analysis guide and research findings of the Five-Year Plan and the Ninth Five-Year Plan.According to synthetical analysis of the statistical parameters of the swarm sequence and some characteristics of the source and medium,the precursory significance of the earthquake swarm corresponding is not obvious.This earthquake swarm may be the result of stress self-adjustment in Linhe fault rift zone under the background of the enhancement of regional stress field during the preparation of three moderate and strong earthquakes in July 2005 in the Yinshan uplift region. |
