The study of neotectonic movements using radar interferometric images is a method that allows studying geological processes that occur on the Earth's surface and are associated with tectonic movements. The process of interferometry consists in comparing the phase of radar signals returning from the Earth's surface, measured from different satellite flights over the same region. This makes it possible to determine micrometer-sized changes in the distance between the satellite and the Earth's surface with high accuracy. The use of this technique during repeated observations at regular intervals makes it possible to detect and measure even small horizontal and vertical shifts of the Earth's surface. This method has great potential for monitoring tectonic movements and changes in the geological environment on different time scales. The use of radar interferometric images makes it possible to detect even minor changes in the terrain, which allows for predicting possible destruction and taking appropriate measures to ensure the safety and preservation of the environment.
