Although acoustic wavefield inversion is widely used, a complete solution of the seismic inversion problem requires that we account properly for the physics of wave propagation, and so must include elastic effects. We have developed a 3D tomographic wavefield inversion code that incorporates the full elastic wave equation. The code uses explicit time-stepping by finite differences that are 4th order in space and 2nd order in time.
