Abstract
A methodology of assessing the stress state of the considered section of the geological medium is offered in this report which allows carrying out a predicted risk assessment in zones of earthquakes based on the analysis of geological data, measurements of local magnitudes in the array and geomechanical modeling. As a result of the study of complex nonlinear systems in the literature scenarios of the occurrence of natural disasters appeared, which are based on a change in the stress-strain state of the rock mass. It allows establishing the causes of catastrophic events, in particular, earthquakes in some cases. Risk management is based on it. Finally, risk management should ensure the safe and stable operation of the enterprise, the safety of the population in the considered territory. The data of monitoring of local magnitudes and results of calculations of stress in the rock mass are used while calculating and analyzing risks.
