Analysis of approaches to solving a forward problem based on a comparison of the results of two seismic tomography algorithms

The seismic ray tomography method provides a way to construct models of velocity anomalies in the geological medium to provide hypotheses about structure beneath. In the tomographic inversion process the chosen approach and quality of the forward problem solution significantly affects final result which may vary for the same dataset. The aim of this paper is to study the influence of the choice in forward problem solving method on the inversion result using two algorithms as an example: PROFIT (ray-bending technique) and ST3D (tracing via eikonal equation solution), using field data (Beltir, Altai Republic, 2021).
