For the separation of intrinsic (forumla) and scattering attenuation (forumla) in South Korea, coda observations represented by the multiple-lapse time windows method were numerically simulated using the direct simulation Monte Carlo method. The simulation showed that the depth-dependent velocity model separated by crust and mantle fit better than the uniform velocity model. Under a uniform attenuation assumption, the forumla and total forumla in South Korea represent the lowest values among current global measurements. These low attenuation values can be explained by the inactive seismicity of South Korea corresponding to those of the seismically stable area such as a shield.
