Recently intrinsic and scattering quality factor (Qi −1 and Qs −1) was successfully separated from total quality factor (Qt −1) on the seismic data of the Korean Peninsula. From this result, we theoretically calculated the expected coda quality factor (QCexp −1) based on multiple scattering model, and compared with other quality factors such as Qt −1, Qi −1, Qs −1, and observed coda quality factor (QC −1) obtained by single scattering model. While the QCexp −1 values are comparable to the Qi −1 values, the QC −1 values are close to the values of Qt −1 rather than Qi −1 and QCexp −1 except for the 24 Hz frequency. This results suggest that the assumption of uniform scatterer in the Korean Peninsula is unrealistic.
