Study of the structure and seismicity of the near-surface zone of the earth's crust at the White Sea seismogenic zone on the Kola Peninsula
The Kandalaksha-Bothnian deep fault is the subject of a comprehensive geological and geophysical study in connection with the development of the Shtokman gas field on the Kola Peninsula. In the process of studying the structure and seismicity of the near-surface zone of the earth's crust in the...
