Urban Paneling based on the Level of Vulnerability Against Natural Disasters (Crisis Management): A Case Study on Nasimshahr
High construction and demographic congestions, low quality of buildings in the body of communication networks and high degree of surrounding and so on lead to loss of sustainability of living environments and an increase in the number of human waste and financial damages in cases of crisis, especially earthquakes. This thesis is basically aimed at identifying the vulnerable places toward natural disasters as well as safe places at the time of occurrence of crisis for temporary residence and analyzing the role of effective factors in vulnerability of urban zones against earthquake.In this study, 7 indices, namely access to healthcare centers, degree of surrounding, construction congestion, demographic congestion, land usage, building longevity and building quality have been adopted, and vulnerability of the zones against earthquake was examined by means of GIS. Results suggest that old textures of Nasimshahr and body of the passages with high construction and demographic congestions, building low quality, too much distance from relief centers vis-à-vis other bodies and high degree of surrounding are highly vulnerable and will therefore have worse condition in crises. Among the zones, initial core of formation of Nasimshahr is the worst in terms of vulnerability and should be prioritized for crisis management in planning.Thus, 70% of residential textures of Nasimshahr are severely vulnerable; almost 20% of them lies within vulnerable limit, and only 10% lies within the less vulnerable limit. Therefore, the research hypothesis concerning vulnerability of the residential textures and variation of the regional vulnerability due to such characteristics as passage width,congestion,material applied in the buildings,against natural disasters is verified.
