Realization of Earthquake Vulnerability Analysis in Structure Scale with Fuzzy Logic Method in GIS: Kadikoy, Maltepe and Prince Islands Sample

摘要

The inadequate evaluation of geologic factors and unqualified and unplanned structuring play effective role ingiant damage and loss of lives created by the earthquakes and faulty areas choice and structure constructioncause building damages during the earthquake, thus it also causes giant loss of lives. Istanbul province and itsimmediate environment are located in north of North Anatolian Fault Zone having 1500 km length. Hence, itcauses that the settlement’s Sea of Marmara coastal region is located in 1st seismic belt. The earthquake risk inIstanbul and related risk factors should be determined besides vulnerability and earthquake risk. Amathematical model has been created in geographic information systems for Kad?koy, Maltepe and PrinceIslands sub-provinces by using Fuzzy Logic method which is one of the artificial intelligence methods byconsidering 4 vulnerability parameters and earthquake vulnerability analysis have been made in this study. Theused 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 buildingsaccording to those levels have been presented via a thematic map. The pre-earthquake precautions should bedetermined for the study field by considering the vulnerability grades in case of any earthquake and the loss oflife and property should be minimized.
