- Abstract:
- By comparison of the seismic waves of MS8.0 Wenchuan earthquake recorded by Hainan Digital Seismic Network and the water-seismic waves,the waveform characteristics of the water-seismic waves were analyzed.We also analyzed the spectrum and time features of the water-seismic waves with high sampling rate of Wenchuan earthquake recorded by five water-level meters of Hainan Seismic Precursor Network by means of FFT and Wavelet Transform.The result shows that the variation between the different wave groups of water-seismic waves caused by the different seismic wave groups were great; the periodic range of the water-seismic wave at the five well in Hainan area were large(from 10 s to more than 1000 s)and the difference of the amplitudes of water-seismic waves at different wells also were great.The formation mechanisms of waveforms and different frequency groups of the water-seismic waves were analyzed preliminarily.
