Seismic wave speed and anisotropy provide essential constraints on the Earth’s internal velocity structure and deformation history. The propagation of the seismic wave can be modeled by a Hamilton system in the forward modeling. Then the best fit depth-dependent anisotropy is obtained by the opti...
