Mantle velocity boundaries of EEP have been specified. For the upper mantle and its tranzi-tion zone dynamics of propagation of mantle velocity limits with depth has been presented. Mantle border area of EEP has been separated and corresponding high velocity inclined layers.

Seismic boundaries of the second kind have been distinguished under Phennoscandia according to three-dimensional P-velocity model of the mantle and velocity number of horizons of the upper mantle and its transitional zone has been shown. Four velocity horizons and corresponding seismic boundaries o...

A three-dimensional P-velocity model of the European mantle built on the Taylor approximation made it possible to analyze the velocity structure of the mantle under the Mediterranean and, in particular, under Central Italy, to a depth of 2500 km. It is shown that the crust earthquakes in Central I...

We consider specific velocity anomalies and the corresponding mantle structures of the East Mediterranean-Black Sea-Caspian region. The anomalies are located on latitudinal and longitudinal seismic tomography sections obtained by constructing 3D P-velocity model of Eurasia applying the Taylor appro...
