Resilience of harbors and coastal utilities under marine hazards is an important issue for post event operations and recovery. Throughout history, in the sea of Marmara where the mega city Istanbul is located at north coast, more than 30 tsunamis in the last two millenniums have occurred.. Istanbul is the highest populated city and center of all economic activities in Turkey. Therefore, many ports are located in the region. Some of these are selected as the case studies for hazard analysis. Main concern of this study is to classify the effects of tsunamis and other coastal hazards mainly on the harbors and harbor operations. Those effects are caused by the direct impact of waves, high water elevations, strong currents, overland flows of water. Not only the structural damage as direct impact but also the loss of property by seiche oscillations due to basin resonance as indirect impact are analyzed. In addition possible structural and functional loss and necessary strategies for reduction of impact and for increase of resilience will also be discussed.
