N2 - There exists a clear distinction between seismic diffractions and reflections in the post-migration dip-angle gather domain. We analyze this distinction and show the possibility of using it for separating and imaging seismic diffractions with only single-offset data as input. When observed in dip-angle gathers, diffraction events are also significantly more sensitive to velocity errors, which opens up the possibility of using them for velocity analysis. We demonstrate the proposed technique on synthetic and real-data examples.
