INTRODUCTION: Natural hazards have been recognized as major causes of the destruction of human settlements. At present, earthquakes are among the most dangerous natural disasters in the world and have always been recognized as important natural hazards. An earthquake is a natural disaster that can create a major catastrophe within a short time, depending on its magnitude. Tabriz, one of the major cities in Iran, is located in a high-risk area according to the earthquake zoning map. The “Tehran Padyr” company conducted the earthquake sub-zoning plan and predicted a maximum of 426,000 casualties in Tabriz. Such seismic potential, along with old and marginal urban areas and historical earthquake records, makes this catastrophic humanitarian crisis predictable. A basic strategy of crisis management is to reduce the harmful effects after an earthquake by establishing temporary housing bases to accommodate affected people. It is necessary to establish temporary housing, rescue, and relief bases based on the identification of potential seismicity, strategic locations, and the presence of more than 1.6 million people in Tabriz.
METHODS: In this study, seven natural and human criteria were chosen to identify suitable land for constructing temporary housing bases. By using the FUZZY-TOPSIS model and incorporating the relevant layers in ArcGIS, the suitability map was extracted. Finally, the optimum locations were selected based on the criteria of area, dimensional suitability, land-use consistency, and ownership.
FINDINGS: This research indicated that seven acres of land comprising four parks in the central and marginal parts of the city were found and selected as the best locations, with very high suitability; 170 acres with high suitability; and 1,339 acres with medium suitability. However, these areas will not meet the needs of the population of Tabriz.
CONCLUSION: According to the results, there is an unreasonable and improper distribution of open spaces for building temporary housing and camps for affected people after an earthquake in Tabriz; thus, urban management and available land in Tabriz will certainly not be sufficient to accommodate or resettle those affected by an earthquake.
