Earthquake — tremors and vibrations of the earth’s surface. According to modern views, earthquakes reflect the process of geological transformation of the planet. It is believed that global geological and tectonic forces are the root cause of earthquakes, but their nature is currently not entirely clear. The appearance of these forces is associated with temperature changes in the bowels of the Earth. Most earthquakes occur on the margins of tectonic plates. It is noted that over the past two centuries, strong earthquakes have occurred as a result of the opening of large faults that come to the surface[1]
Every year, more than a million earthquakes are recorded by the instruments. The increase in the number of observation points and the improvement of instruments for recording seismic vibrations have made it possible to record more and more earthquakes occurring in the bowels of the planet every decade.
