The structure of the crust and upper mantle in Finland has been studied by utilizing results of surface wave phase and group velocity determinations and of explosion seismic refraction measurements. The dispersion curves for a set of theoretical models have been calculated by the Thomson-Haskell matrix method. The earth-stretching transformations of Anderson and Toksoz were used in the calculation of Love wave dispersion. The derived layer model has a crustal thickness of 42km and a major crustal discontinuity at the depth of 12km. The existence of a low-velocity layer in the upper mantle with the upper boundary of it at a depth lower than 150km could not be shown with the available data.
