The inadequate evaluation of geologic factors and unqualified and unplanned structuring play effective role in giant damage and loss of lives created by the earthquakes and faulty areas choice and structure construction cause building damages during the earthquake, thus it also causes giant loss of lives. Istanbul province and its immediate environment are located in north of North Anatolian Fault Zone having 1500 km length. Hence, it causes that the settlement’s Sea of Marmara coastal region is located in 1st seismic belt. The earthquake risk in Istanbul and related risk factors should be determined besides vulnerability and earthquake risk. A mathematical model has been created in geographic information systems for Kadıkoy, Maltepe and Prince Islands sub-provinces by using Fuzzy Logic method which is one of the artificial intelligence methods by considering 4 vulnerability parameters and earthquake vulnerability analysis have been made in this study. The used parameters are the location by fault line, geologic structure, building structure and the number of floors. The vulnerability grades emerged as a result of analysis have been studied and the distribution of buildings according to those levels have been presented via a thematic map. The pre-earthquake precautions should be determined for the study field by considering the vulnerability grades in case of any earthquake and the loss of life and property should be minimized.
