From: New approach to detect seismic surface waves in 1Hz-sampled GPS time series
Frequency spectra of the residuals presented in Figure 9.
a) Amplitudes of the Fourier spectra of the GPS residuals computed for data recorded before the seismic wave arrival. Peak frequencies are located below 25mHz. b) Amplitudes of the Fourier spectra of the GPS residuals plotted in Figure 9. Peak frequencies are located around 30mHz.
