The incredible technological development of the last decades, the globalization of at least information, the cooperation at state, regional, global level, the removal of autistic dominant centers from the planetary equation and the appetite imposed by the increasing frequency of disasters and their effects have now led to a new beginning: a beginning of the challenge of the human struggle for man, for a climatic good, not against nature, for survival. In order to reduce the destructive potential generated by a natural disaster and the analysis of risks and vulnerabilities, man can intervene both in environmental control (stopping deforestation, pollution, irrational excavations) and through a more careful, more applied approach to technological elements. which may be the premises for the occurrence of a negative phenomenon (accidental pollution, nuclear accidents, global warming, hydrological hazard) thus increasing risk resistance and reducing vulnerability. Through an analysis of risk and vulnerabilities and a package of concrete and precise data covering the entire state level of critical infrastructure, private assets and particularities of communities, an impact assessment can be obtained that adjusts both response plans. but especially financial planning and economic development projections to offset the social, economic and environmental costs of the disaster. Such a pre-event and post-event evaluation can be the foundation of a future strategy. The main objective of the article is the analysis of the main categories of risks that define the management system of emergency situations based on the connection between them.
