Three-dimensional P-velocity model of the mantle and seismicity of Fennoscandia.
Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2019 The paper analyzes the three-dimensional P-velocity model of the mantle of North-West Europe (Fennoscandia) in order to isolate the connection of the earth's crustal earthquakes and processes in the mantle.

Earthquake in central Italy and velocities structure of the mantle
Геофизический журнал, 2018 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
