Objective: The Tehran metropolitan area is recognized as a region with a high seismic hazard. The accumulation and compaction of the built environment, coupled with the high population density in this region, have amplified concerns regarding the potential damage and casualties resulting from a possible earthquake. While various dimensions of vulnerability to earthquake hazards have been studied by researchers at the neighborhood and district levels within the Tehran metropolitan area, the vulnerability of rural settlements in this region has not been adequately investigated. Due to this scientific and practical gap, the aim of the present research is to analyze the spatial pattern of vulnerability in rural settlements in the Tehran metropolitan area.
Method: This research was conducted using quantitative methodology and is classified as applied research. The study population includes 1,082 inhabited rural settlements in Tehran and Alborz provinces. Among them, 914 villages with accessible statistical data were included in the analysis. Data collection was conducted using a library method, mainly using statistical data from the Statistical Center of Iran. Fuzzy inference systems, kriging interpolation methods, and hot spot analysis techniques were used for data analysis.
Results: The research findings indicate that all rural settlements located within the Tehran metropolitan area have a high potential for earthquake vulnerability. Moreover, the spatial pattern reveals a higher level of vulnerability among settlements located in the peripheral zones compared to those located in the central areas of the Tehran metropolitan area.
Conclusions: The spatial distribution of rural settlements within the metropolitan area of Tehran shows different levels of vulnerability to earthquake hazards. This disparity is influenced by both natural spatial dynamics and socio-economic structures, as well as the interactions between these two factors. Rural settlements closer to the urban center generally have more favorable conditions due to better access to essential infrastructure. Conversely, those further from the center have limited accessibility and resources. |
