Modelling Riskable Regions Crisis Management in Urban Areas A Case Study of District 8 of Tabriz

Today the increasing population of the world in urban areas and developing countries especially in metropolitan cities susceptible to earthquake has necessitated a wider look at the natural events and tragedies resulting from them. Tabriz is considered to be one of the most susceptible cities to earthquakes due to the existence of active faults. Meanwhile, Tabriz 8 municipality district, as a cultural and historical municipality, has valuable historical places with worn-out texture, heavy traffic, and large population which make it of paramount importance to do research in the area of crisis management. In the present study, attempt is made to sort out riskable levels of the region in district 8 using the weight overlap indexical model in the GIS environment. The layers used in this model include distance from faults, construction quality, population growth and proximity to passages, proximity to open spaces, firefighting station, military places, gas station, and the topography of related area of study. Results obtained from the model indicate that only %13.94 of related area of study has optimal and a more optimal condition. %47.37 of the area was in normal condition in terms of risk ability in critical time. %38.69 of the area was in various undesirable situations which necessitates careful and regulated planning before, during, and after the crisis on the part of authorities. It should be pointed out that this article has been extracted from the Ph. D dissertation under the title of" The policies of crisis management in urban worn-out textures: A case study in district 8 of Tabriz municipality".
