Title: Monitoring System of Seismo Dynamics of Rocks for Recording Earthquake Precursors
Keywords: utomation; displacement measurements; earthquake precursors;

Abstract: Internet of things (IoT) and smart city technologies are closely related to citizen security issues. One of the important components of safety is to reduce damage from man-made and natural disasters. In this area, the most important direction is the continuous monitoring of rock vibrations under the influence of tidal forces. These technologies, with minor changes, can be used to monitor the state of complex technological structures, such as dams, bridges, large buildings. It is known that continuous recording of micro deformations of rocks under the action of gravitational forces from the Sun and the Moon due to a change in their location in relation to the Earth's surface allows one to obtain additional information about the possible future earthquakes. The corresponding meters are based on two helium-neon (He-Ne) lasers. They contain a rather complicated and insufficiently reliable system for automatic phase and frequency tuning of the slave laser to the master. Insufficient accura
