Abstract
We examine extreme natural processes and hazardous phenomena which are observed in the Far Eastern region: earthquakes, tsunamis, avalanches, mudflows, cryogenic processes, extreme low temperatures, floods, thunderstorms, fires, snow storms, fogs, water erosion, karst, glaciers, etc. Various territorial combinations of these processes and phenomena have been identified. Spatial coverage of the research is a macroregion which is considered as an aqua-territorial region of Pacific Russia, including the territory and adjacent water areas within the 200-mile maritime exclusive zone. This aqua-territorial macroregion is characterized by active regional environmental management, including the utilization of natural resources of the coastal land and resources of marine waters. However, many extreme natural processes and hazardous phenomena occurring within marine areas have a negative impact on coastal land. An assessment is made of the territorial and aqua-territorial combinations of the extreme natural processes and hazardous phenomena in Pacific Russia. We constructed maps of several versions of zoning according to the difference of combinations of extreme natural processes and hazardous phenomena, including their 25 types. We identified 10 types of territories of Pacific Russia with various combinations of these phenomena and processes, and their generalized characteristics are provided.
