In this paper the geometrical properties of the bi-characteristic curves are employed in developing a new approach to 3D modelling of elastic piecewise homogeneous media, in particular Earth crust and upper Mantle. The method is based on tomography and the refraction, respectively, reflection, of the bi-characteristic curves at the layer boundaries of multi - layered media. 2000 Mathematics Subject Classification: 35L53, 35Q86, 86A15.
