Abstract

We propose an effective scheme for incorporating anelastic attenuation in synthetic seismograms for transversely isotropic media, where the scheme uses only two kinds of quality factors Q: QP and QS instead of five kinds of Q corresponding to five independent elastic constants. It is a straightforward extension of the scheme for isotropic media in the reflectivity method. We implement our scheme in a reflectivity code for transversely isotropic media, and show some numerical examples to illustrate feasibility of the scheme.
