Spatial site safety analysis for Bakirkoy district of Istanbul

Abstract

Spatial earthquake risk analysis has been carried out for the Bakirkoy district. The analysis consisted of stages of geological, geotechnical evaluation and seismic microzonation using the data obtained from an extensive programme of borings, geophysical tests, SPT measurements and soil/rock mechanics laboratory tests. Four different approaches are applied to find response spectra and the results are cross-examined to represent the local site effects. The findings are presented on the maps prepared by the application of GIS methodology.
