Short summary
A wave-equation-based travel-time seismic tomography method is developed including a detailed description of its step-by-step process. The forward problem is solved in the two-dimensional (2-D) vertical plane passing through the source and the receiver, and the final model is parameterized on 3-D inversion grid nodes. This 2-D--3D tomography method takes into account finite-frequency effects, accurately simulates seismic wave propagation in complex media, and has great computational efficiency.
