Reply by the authors to B. Gurevich
We thank B. Gurevich for interest shown in our paper. In exploration seismology, as noted by Dr. Gurevich, one can model effects in porous media by using the elastic wave equations with trial densities and velocities. Indeed we have, in the past, followed the approach discussed by Gurevich and modelled the earth with a single density and velocity structure in particular layers to simulate the combined effect of a fluid and a solid matrix on a number of occasions (Vafidis et al, 1992; Dai et al 1990) just to point out two papers. Our experience, particularly with higher frequency 3‐D data, is that the synthetic results never match field results and that more parameters are necessary to model partition of energy between different kinds of waves at the interfaces.
