Active Faults as a Factor of Natural Hazard and Risk of Nature Management
EDN: TIOGAS
Abstract
The study considers active faults and areas of their dynamic influence, where dangerous geodynamic processes and phenomena develop due to seismotectonic activity. They can lead to natural disasters, and authorities introduce natural and natural-technogenic emergencies at sites and territories. For one reason or another, areas of active faults quite often fall within the competence of economic development, the creation of linear and point production infrastructure: pipelines, power lines, industrial and social facilities, urban and agricultural lands, etc. For designed and already functioning enterprises and development zones, the legislation of the Russian Federation establishes the need for a strict assessment of the impact on the environment, including the risk of any economic and other human activity. Therefore, active faults are a formidable factor of natural hazard and risk of nature management. Their study from this angle is rare in scientific literature today, which determines the relevance of our work.
The article presents the methodological foundations for studying active faults. For this purpose, some postulates of structural geomorphology are additionally clarified and specified. It is proposed to subdivide the danger of active faults into hidden and obvious, localized/sudden and diffuse/constant, directed at humans, man-made or the surrounding natural environment. The tasks and prospects of research in this area are defined, a connecting thread is drawn between the development of the relief of fault zones, dangerous geomorphological and active geodynamic processes and the entire natural-territorial complex, landscape and economic and household environment. Active faults are a serious factor of natural hazard. It can actually cause the activation of dangerous geodynamic processes in scale and strength, the emergence of a risk of nature management for humans, the economy and territories, economic infrastructure. The question of how they can influence the level of seismic hazard is considered.
