The article considers problems and prospects of reducing the risks of occurrence of emergency situations of natural and technogenic character in the coastal river areas, as well as the usage for operational informing of the population of a comprehensive system that includes Federal, regional and local information centres. It is shown that the solution of the problem is based on the formation of information about emergency situations, their consequences, the state of radiation, chemical, medical, biological, explosive, fire and environmental safety in these areas, taking into account the coastal and transboundary situation to ensure their sustainable development. The authors defined the indicators and presented a strategy for collecting information and proposed a comprehensive system of support for management decisions aimed at preventing natural and man-made emergencies for the river coastal territory (RCT) of the Far East regions.
