Application of GIS techniques in disaster relief after earthquakes in urban areas and provide an appropriate model for the organization (the region: District 3 of Tehran)

In this research, the application of GIS techniques to post-earthquake relief in Tehran's Municipality 3 and the provision of a suitable model to relief agencies were discussed. To conduct research, 10 effective measures were selected based on library studies and experts' opinions. The criteria were entered into the GIS software as a digital layer. The Euclidean distance maps were prepared and the layers are matched with fuzzy membership functions. Then weighted in Expert Choice software and according to the weights obtained were combined. The weight of the criteria included: treatment centers, population density, green spaces, building floors, type of materials, land use, building area, distance from faults, aqueducts and street widths after comparison, the couples obtained 0.081, 0.047, 0.206, 0.036, 0.051, 0.103, 0.074, 0.021, 0.049, and 0.022 respectively, respectively. The final map of the vulnerability showed that the total study area was 360.0082, 706.4217, 555.3693, 238.6628 and 102.2051 hectare, respectively, at high, low, moderate, high and very high levels respectively.
