Abstract
Duzce in Turkey was severely damaged during the November 12th, 1999 earthquake (Mw 7.2). The paper presents different surveys and studies performed after the earthquake, which resulted in the microzonation study of the city. At first we collected and analyzed all available geophysical and geological data. Then we performed a well focused geophysical and geotechnical campaign comprising a sufficient number of shallow and deep boreholes, seismic down-hole tests, array measurements of microtremors and ambient noise measurements. The synthesis of all these data resulted in the construction of the seismic geotechnical map and the geometry of the “seismic bedrock” of the city, adequate for site effect analysis. At a second stage we performed a thorough analysis of all available strong ground motion records and we carried out a detailed seismic hazard analysis, which provided the necessary input motion characteristics for the spatial analysis of the seismic ground response. Finally, we conducted a specific site effect analysis for the seismic scenario of the 1999 earthquake with a series of conventional 1D EQL analysis. The processing of the theoretical analysis results led to the estimation and the spatial distribution of the mean acceleration, velocity and displacement response spectra. As a result, Duzce was divided in seismic zones and for each one we proposed the corresponding mean design acceleration response spectra and all other characteristics of the expected ground response.
