From: Simulations of P-SV wave scattering due to cracks by the 2-D finite difference method
(Color online) Results of the simulations obtained for Model 1 (ϵ = 0.0125) with P wave incidence on horizontal cracks. (a) Vertical- and (b) horizontal-component synthetic seismograms (the cloud of thin light blue lines), and the synthetic mean wave and its standard deviation derived from these seismograms (solid and dotted blue curves, respectively). The predicted mean wave is indicated by the red curve, though almost masked by the solid blue one. The thin black curve denotes the initial wavelet that would be observed without the cracks. (c) The close-up of the primary part in (a). The synthetic seismograms are omitted. (d) Q−1, and (e) δv for the synthetic mean wave (blue curves). The prediction by the FAT is denoted by red curves.
