In his Opinion article, “Thirty Years of Confusion around `Scattering Q'?” in SRL 80 (1) (hereafter referred to as M09), Igor Morozov briefly reviews seismic attenuation studies and criticizes virtually all of them as being based on improper model parameterization and interpretation of results. Morozov is correct in stating that many attenuation studies quantify the effect of wave front expansion on amplitude measurements by the “geometrical spreading term (GST),” which he calls G0(t) (Equation 1 of M09). However, it is not true that the subsequent attenuation measurements are always conducted using the parameterization of seismic quality...
