We propose a quasi-compressional wave (qP-wave) traveltime inversion technique for determination of the 2-D horizontal and vertical qP-wave velocities and depths to interfaces from seismic reflection/refraction data sets. Synthetic test model studies demonstrate that the method is effective if ray-path coverage within the model is adequate, and indicate that horizontal qP-wave velocities and depths to interfaces are better resolved than vertical qP-wave velocities.
