Abstract
Mathematical properties of the inverse dynamic seismic problem for determining the elasticity parameters of a homogeneous layered anisotropic medium are investigated for the case of orthorhombic symmetry. Analysis of the mathematical properties of the inverse problem allows predicting which parameters can be estimated to a satisfactory accuracy. The suggested inversion algorithm is tested in numerical experiments for determining elastic parameters of a thinly stratified medium including several anisotropic layers.
