Abstract :

Determining the right directions for urban development has been one of the concerns of urban planners. Geomorphologists also consider one of the solutions for their involvement in urban planning to determine the direction of city development based on geomorphological findings. The physical development of cities is directly related to the natural environment and geomorphological effects. The development of cities in semi-mountainous areas such as Bojnord is highly sensitive due to geomorphological limitations and the instability of the slopes. Due to its unexpectedness, these risks leave a lot of human and financial damage in most cases. Earthquakes are environmental hazards that cause a lot of casualties and damages. Therefore, it is very important to identify areas prone to earthquakes and landslides, in order to apply methods of prevention or dealing with the instability of the areas in order to reduce the risk and risk resulting from them. The purpose of this study is to locate cities with emphasis on geomorphological limitations. For this purpose, among the most important factors affecting the earthquake, the 6 factors of the amount of slope, the direction of the slope, the type of geological materials, the distance from the fault, the acceleration of the earthquake and the amount of rainfall, whose data were possible to prepare for all Bojnord cities and towns, The basis of engineering judgment were classified in the GIS environment. And then the zoning map of earthquake risk was prepared in the GIS environment. Therefore, the earth and earthquake risk map helps designers and engineers to choose the right location for the implementation of sustainable urban development plans, which will not be possible without considering the limitations and planning and management. The results of this research show that this province has the greatest threat in terms of geomorphological limitations of earthquakes.
