| Popis: | The relevance. Geodynamic instability is the cause of many natural disasters: earthquakes, volcanic eruptions, landslides, tsunamis. Natural disasters can trigger man-made accidents (collapse of buildings and structures, explosions in mines, dam integrity violations, etc.) and, conversely, man-made processes can cause the emergence of new natural objects, for example, they are associated with the creation of artificial reservoirs. The widespread oil and gas production in the world can provoke movements in the earth's crust with tragic consequences. The features of conditions for activation of geodynamic instability determine the level of safety of personnel of technical facilities and the quality of operation of facilities, systems and units. The random nature of the processes in the earth's crust to a large extent forms the possibility of predicting man-made disasters and measures to parry the negative factors associated, including the safety of personnel and the population. Examples of natural and man-made disasters and the conditions of their occurrence as well as the recommendations for their prevention and prediction are given. Different points of view on activation of hemodynamic instability of the Earth, as well as the influence of seasonal periodicity of characteristic processes on it were compared. The level of significance of the earth motion parameters in the formation of the conditions of activation of geodynamic instability is substantiated. The relevance lies in the need for additional research in this area, which is partially filled by this article. The aim of the research is to identify and propose an approach to analyze the catastrophic situation conditions. Objects: geodynamic processes in the earth's crust and variants of combination of conditions for their occurrence. Methods: review and analysis of existing scientific and technical information on the problem of geodynamic stability of the earth's crust and formulation of research tasks. Results. The causes of emergency situations associated with geodynamic processes in the earth's crust are identified and justified. |
