Abstract
The article presents the hypothesis of lithospheric plate tectonics and its significance in the location of earthquake and volcanic eruptions on Earth. Information is given on the largest earthquakes in terms of energy and the number of victims of earthquakes on our planet with reference to plate tectonics, including earthquakes in Turkey and Syria on February 6, 2023. An increase in the role of geodesy in the study of geodynamic phenomena in recent decades is shown in connection with the introduction of satellite measuring instruments, which make it possible to determine distances of hundreds and thousands of kilometers with an accuracy of the order of 10-8–10-9 parameters of the Earth, as well as to determine the propagation of deformations from strong earthquakes on the earth's surface. It is concluded that the strongest earthquakes provoke deformations of the earth's crust, covering vast territories of the Earth with an area of hundreds of thousands and millions of square km.
