摘要
采用一阶差分、滤波、五日均值等方法对临潼台水氡、水溶气资料进行了分析研究,认为:1998年1月5日泾阳4.8级和2002年2月5日宝鸡3.4级地震前临潼台流体均出现了明显的短临前兆异常;泾阳地震的异常时间比宝鸡地震长;两次地震前流体异常幅度明显不同,异常幅度与震级关系不明显。
Water radon and water-dissolved gas data are analyzed by the method of first order difference, digital filtering and 5-days-mean values. It is thought that data of subsurface fluid has obvious precursory anomalies with short term and imminent term before Jingyang earthquake and Baoji earthquake at the Lintong Seismic Station. Precursory anomalies before the Jingyang earthquake lasted much longer than that before the Baoji earthquake. The ranges of precursory anomalies before the mentioned two earthquakes are obviously＇ different. The relation between range of precursory anomalies and magnitude is not evident.
