Ranking of rural settlements in environmental hazards (case study: Central district of Ardebil Town )

The special environmental, climatic and geographical conditions of the country have provided the ground for the occurrence of various environmental hazards, especially in rural areas. In this regard, due to the weak nature of the physical element of rural settlements, earthquakes are the most important natural hazard that has seriously challenged such habitats. The passage of several important and dangerous faults from the study area (Ardabil Town) has caused a higher seismic potential than other areas of the province. The present study uses a descriptive -analytical method and utilizing more capabilities of the Vikor model than other proposed models (TOPSIS, etc.) to evaluate the efficiency and operation of this technique in combination with the Geographic Information System (GIS). In order to prioritize 29 sample rural settlements in the central part of Ardabil Town in terms of vulnerability to earthquake risk. The required data about the 4 main research indicators (including: depth of the earthquake occurred in the area; lithology; distance from the fault; and the magnitude of the earthquake) were also collected in a documentary manner and the final weight of the indicators based on the opinions of 15 relevant experts and The use of AHP method has been determined. According to the final output of the Victor model, the northern part of the central part of Ardabil Town, including: East and West Arshaq villages, which include the sample villages of Khajeh Bolaghi, Gol Tappeh and Aq Qaleh and are adjacent to the main faults, are more at risk of earthquakes. Are; And in the next ranks are the villages of Sardabeh and Kalkhoran, etc.
