【摘要】 2003年5月初至2003年10月下旬,聊古一井气体总量现明显的低值异常过程,在对上述异常变化进行现场分析落实的基础上,结合对聊古一井水化学测项投测以来地震异常特征和聊古一井水化学测项前兆意义的分析结果,认为聊古一井气体总量的异常变化属场兆异常,可作为该井周围不同地震构造带上发生5级以上地震的一种判据。聊古一井气体总量异常过程较好地对应了2003年11月25日山西洪洞发生的5.0级地震。更多还原

【Abstract】 The inventory of total gases had shown outstanding lower anomalous change in Well Liaogu-1 from May. 2003 to Oct. 2003. We believed that the above anomalous change belongs to the seismic precursor of tectonic field and takes as a kind of mark which indicates earthquakes with MS≥5 may occur along different seismic structural belts around the Well Liaogu-1, based on analyzing and verifying above anomalous change in the field, and combining with the analyses of the anomalous change of earthquake precursors and the prediction significance of the seismic precursors of hydrochemistry elements in he Well Liaogu-1 since observation. The above anomalous change was corresponded to Hongdong earthquake with MS = 5.0 that occurred along Shanxi seismic belt in Nov. 25, 2003. We take the anomalous change as Hongdong earthquake s precursor from tectonic field.更多还原
