Deep velocity structure of the crust and the upper mantle of the continent of Asia has been investigated on the basis of the representative set of group velocity dispersion curves of Rayleigh waves (more than 3 200 paths). We applied a tomography method for spherical surface to image group velocity distributions in the period range 10–250 s. Average dispersion curves have been calculated for eight tectonic regions and then have been inverted to vertical shear wave velocity sections up to the depths of about 700 km. The results obtained allow us to explore main features of the deep velocity structure. Also they may be used as initial data in further detailed investigations of the continent of Asia.
