Afet Toplanma Alanlarının Yer Seçimi ve Yeterliliğinin Değerlendirilmesi: Siirt Kenti Örneği

Abstract

Türkiye is one of the most affected countries in the world by natural disasters (earthquake, flood, landslide, avalanche and rock fall). The number of events caused by natural disasters in Türkiye in 2022 is 22,982. Therefore, it has become a necessity to determine disaster assembly areas in cities and to make the infrastructure and physical qualities of cities resilient. Siirt city, located in the Southeastern Anatolia Region of Türkiye, is open to be affected by many disaster events due to its location. In this study, it is aimed to evaluate the adverse conditions that will arise during and after natural disasters in Siirt city and to analyse the suitability of existing assembly areas by using GIS method. In Siirt, 25 disaster assembly areas were determined by AFAD in 20 neighborhoods. A significant portion of these gathering areas are open and green spaces within the neighbourhoods. There are fault lines that can produce major earthquakes in the immediate vicinity of the city of Siirt, and as a matter of fact, major earthquakes have occurred in these areas in the past. As a result of the evaluations made, it is seen that the existing assembly areas of the city in case of any disaster are inadequate in comparison with other criteria, especially population. As a result, Siirt has a fragile structure in terms of infrastructure, building stock and settlement pattern.
