Seismic propagation forward models form the basis of seismic tomography and are one of the main constraints on the quality of seismic inversions. Many approaches exist to describe the first arrival wavefront propagation. We examine four classes of first arrival models, evaluating and comparing their failure modes and computational cost, as well as suitability for massively parallel GPU implementation.
