The wave-equation wavefront migration (WWM) is a potentially efficient form of wave equation migration, where the finite-difference stencil is only applied around the leading portion of the wavefront. WWM has the accuracy of wave-equation migration, fewer aliasing and migration artifacts, and can potentially be much faster than the standard reverse-time migration. The potential drawbacks are the memory intensive operation of storing the Green's function at each grid point, and that only a fewdoi:10.1190/1.2792914 fatcat:2stlvpono5apbbrxrrsgjxvcde
