Short summary
Seismic waves attenuate with distance due to two effects: (1) removal of energy by internal friction and (2) redistribution of energy into different distances and time windows by scattering from heterogeneous Earth structure. The relative contribution of these two effects is estimated by synthesizing seismograms having varying amounts of internal friction and heterogeneities. The attenuation of observed S waveforms requires contributions from both internal friction and scattering.
