We discuss the single scattering model by using seismic array data. By analyzing observed seismic array records, we found that coda energy level for slant‐stacked record is smaller than that for single station record as expected from the single scattering model. The energy level of slant‐stacked waveform is dependent on stacking direction. The energy level variation for different slant‐stacking directions suggests that horizontally aligned scatterers predominate over vertical ones. The present analysis is probably useful to detect scattering anisotropy.
