Assessment and evaluation of urban vulnerability to earthquake in the province of Ilam

Any imbalance in intra-city systems (urban spatial and urban areas) and external systems of the city (near and far-reaching districts of the city and region) causes its uncertainty and instability. As a result, estimating the risk and assessing the seismic vulnerability of a city is also considered as a major issue. The present study, with the developmental-applied and combination of field and library methodology and using the VIKOR method, has studied the issue in Ilam province. The results show that the cities of the province in terms of demographic density, literacy, etc. Each of them has an effective role in vulnerability, they can be effective in the damage caused by the earthquake. VIKOR and GIS models show that the regions in which these indicators are higher than other areas (surplus of defined standard) is not in the benefit of the region and if this surplus is in the benefit of the region. Statistically, the average VIKOR score was 0.125%. Though this amount expresses the situation inappropriately. But there are areas where VIKOR levels are much smaller than the average. Which includes the Dehloran, Ivan and Maleshahi cities
