B.L.Lichkov wrote about the great role of the Earth's rotation and the change in time of its rotation rate in the occurrence of earth deformations. He also emphasized the paramount importance in tectonics of the impact on the lithosphere of the Earth's outer shells - the atmosphere and hydrosphere ...

The most complete schemes of the tectonic structure of Kamchatka were made by M. F. Dvali and B. F. Dyakov. F. Dyakov. A numerous group of volcanologists headed by A. N. Zavaritsky paid much attention to the issues of disjunctive tectonics of Kamchatka and the Kuril Islands. The works of the team of geologists and geophysicists of the expedition vessel “Vityaz” were of great importance in understanding the tectonic structure of the Kuril Islands. In addition to these works of regional importance, the issues of tectonics of certain areas were covered in various geological studies.
