文安5.1级地震前兆变化特征分析
ON PRECURSOR VARIATION CHARACTERISTICS BEFORE WENAN M5.1 EARTHQUAKE
【摘要】 对2006年7月4日河北文安Ms 5.1地震前兆变化特征进行了总结。震前的异常特征显示,前兆变化的群体性、配套性和加速性具有强震孕震特征;三马坊、昌平台地温变化在时间上对文安地震有指示意义。另外,通过对文安地震前兆变化的总结,认识到综合预报、异常落实、异常跟踪和深入研究的必要性。
【Abstract】 The characteristics of precursor variation before the M5.1 earthquake on July 4,2006,in Wenan of Hebei province is summarized.It is considered that the large number,completeness and acceleration of precursors are the characteristics of a coming strong earthquake.The geothermal variations at Sanmafang and Changping stations have the significance indicating the occuring time of Wenan earthquake.Through summarizing the precursor variations of Wenan earthquake,the necessities of synthetical prediction,precursor verification,precursor following and the further study are understanded.
