Abstract:The tide admittance analysis for the semidiurnal wave of the earth tide by use of the vector pattern of ground tilt observed at seismostations is expounded.As an example,the tilt vector pattern at the Zhangzhou station,Fujian,was processed.The results show that the tide admittance of the semidiurnal wave in a short scale of time(one day) can be taken for a complement to the Venedicov harmonic analysis,at the same time,the picture of tilt vector pattern is helpful for tracking the characteristics of space-time change of the anomalies before an earthquake.
Keywords:tidal tilt  vector pattern  semidiurnal wave  tide admittance  characteristics
