    Abstract:

    This paper uses the complex relative analysis method to extract anomalous information in earth tide of well-water level before earthquakes and offers the numerical standard distinguishing the anomalies quantitatively. The daily atmospheric pressure coefficient replaces the mean atmospheric pressure coefficient so as to correct the effect of atmospheric pressure on well-water level. It is suggested that anomalous rate of data and reflective ratio of anomaly to earthquake can be taken as standard distinguishing observed quality of water-level data. Finally, a practical example using this method is cited.
