We use the Kirchhoff prestack depth migration to calculate migrated sections in simple anisotropic homogeneous velocity models in order to demonstrate the impact of rotation of the tensor of elastic moduli on migrated images. The recorded wave field is generated in models composed of two homogeneous layers separated by a non-inclined curved interface. The anisotropy of the upper layer is orthorhombic or triclinic with the rotation of the tensor of elastic moduli. We apply the Kirchhoff prestack depth migration to single-layer velocity models with different types of anisotropy: orthorhombic and triclinic anisotropy with and without the rotation of the tensor of elastic moduli. We show the errors of the migrated interface caused by incorrect velocity models used for migration. The study is limited to P-waves.
