摘要
对2003年度银川基准地震台重力观测资料进行潮汐分析和非潮汐分析,提取出2003年10月25日民乐山丹地震前3个月出现的异常信息,通过对银川台观测条件、仪器的工作情况和数据精度的分析,表明此异常信息可信,阐述一定距离范围内发生地震时,重力观测短临异常的形态特征。
Tide and no-tide analysis have been made to gravity observation data in Yinchuan Station in 2003.The anomalous information that appeared 3 months before Minle-Shandan Earthquake occurred in 25,October has been abstracted.Through analyses to observation condition,working situation of instrument and data precision of Yinchuan Station,the anomalous information has been showed to be certain.The shape features of the impending anomaly of gravity observation have been described when earthquakes occur in certain distance range.
