Integration of Kernel model (KDE) and AHP Model in order to Evaluate the Earthquake Risk in Urban Squatter and Timeworn Textures by Geographic Information System (GIS) A Case Study in Tabriz (municipal areas No. 1 and 5)

Evaluation of the vulnerability is one of the most important challenges facing metropolises in Iran. Sensitivity of the issue is duplicated when the city is not only timeworn and includes squatter areas، but also is exposed to natural disasters such as earthquake and flood. Zoning the risk of earthquake and its modeling by advanced techniques regarding the vulnerability level of cities is inevitable. In Tabriz، diversity of urban textures، proximity to fault lines and lack of precision and revision on the subject، increases the vulnerabilit of such textures besides squatter textures. This project studies the municipal areas (1 and 5) in Tabriz city، regarding the nature of earthquake and its relation with four factors: population density، building density، quality of buildings and types of materials. Furthermore، the relation of vulnerability due to earthquake has been studied and modeled taking the advantage of the GIS robust technique with integrating Kernel Density Estimation model (KDE) and Analytical Hierarchy Possess model (AHP) in order to determine the vulnerable areas more precisely with an emphasis on residential application.
