(a) Configuration of the numerical simulations without land. The solid triangles, open circle, and dots denote receivers, a scatterer (island), and noise sources, respectively. (b) Waveform retrieved by the time derivative of the cross-correlation function (red) and the synthetic waveforms of the Green’s functions between the two stations (black) for the configuration of Fig. 5(a). (c) Configuration of the numerical simulations with land (shaded), inside which no noise sources exist. The locations of the receivers and the scatterer are unchanged from Fig. 5(a). (d) Waveform retrieved by the time derivative of the cross-correlation function (red) and the synthetic waveforms of the Green’s functions between the two stations (black) for the configuration of Fig. 5(d).
