Abstract
Summary. In order to separate the scattering effect from the intrinsic attenuation, we need a multiple scattering model for seismic wave propagation in random heterogeneous media. In this paper, we apply radiative transfer theory to seismic wave propagation and formulate in the frequency domain the energy density distribution in space for a point source. We consider the cases of isotropic scattering and strong forward scattering. Some numerical examples are shown. It is seen that the energy density-distance curves have quite different shapes depending on the values of medium seismic albedo Bo = qs/(qs t q,), where vs is the scattering coefficient and va is the absorption coefficient of the medium. For a high albedo (B> 0.5) medium, the energy-distance curve is of arch shape and the position of the peak is a function of the extinction coefficient of the medium ve = qs + qa. Therefore it is possible to separate the scattering effect and the absorption based on the measured energy density distribution curves.
