On the basis of the original location-based technology developed by the authors for constructing seismic images of the deep structure of the earth’s interiora method is proposed for estimating the seismic wave propagation layer velocities. The technology ensures the unambiguity and stability of seismic imaging by successively solving direct kinematic problems for all reflecting boundaries. It consists in locating the reflection pulse’s sources from the boundaries of the deep section’s layers and restoring the kinematic parameters of the layers through them. To assess the next layer velocity, information is used on the parameters of the preceding boundaries and the direct kinematic problem’s solution with the additional equality’s condition of local velocities at the reflection’s points from the underlying boundary.
