Local seismic tomographic study has been conducted according to the data of 200 weak earthquakes occurred in 1975-2010 and registered by seven seismic stations in the area of the Kerch peninsula and adjacent northern part of the Black Sea. Application of Backus-Gilbert method for the three-dimensional case allowed to study the velocity structure by P- and S-waves at the depths of 15-40 km and to calculate the ratio VP/VS. Two high velocity blocks have been revealed in the middle and lower crust
