Methodology for Identification and Assessment of Zones and Facilities of Increased Seismic Risk within the Boundaries of Urbanized Areas

The research methodology is based on best practices and modern achievements, and consists of using an algorithm for identifying areas of increased natural and man-made hazard and assessing them and the objects of increased seismic risk located in these areas within the boundaries of urbanized areas. The purpose of this methodology is to assist developers of zoning schemes in identifying and assessing highrisk areas in urbanized areas, particularly in seismic zones, which are crucial for making effective management decisions. Mapping (zoning) of urbanized areas using this methodology is the basis for identifying the urban development value of land plots and "inconvenient" areas, including in terms of investment attractiveness. This paper introduces new term "territory seismic risk coefficient"— a coefficient reflecting the level of potential impact of one or several seismic risk factor studies simultaneously affecting a specific area of the city. The seismic risk level of an area depends on the area of potential impact of secondary factors and their consequences (hereinafter referred to as an emergency situation) in relation to the permissible area of damage to the territory of a city (district, quarter) during a design earthquake. The area is ranked based on the hazard level of the area in accordance with the recommendations of the Civil Defense and Emergency Situations Ministry, where hazard levels I, II, and III correspond to Sij values equal to 50, 30, and 20% of the city (district, block) area. The development of the Methodology takes into account UN-HABITAT's key approaches to sustainable development, as well as the principles and models recommended by international seismic hazard reduction standards.
