I present two case studies which describe applications of engineering seismology in urban areas: High-resolution shallow offshore 3D seismic survey for the Bosphorus Subsea Road Tunnel Project, and seismic, geotechnical, and earthquake engineering site characterization for a residential project in Istanbul. In Case study 1, I conducted a 3D high-resolution shallow seismic survey in 2011 to confirm the geometry of the future Bosphorus Subsea Road Tunnel traverse. I processed the data to obtain 3D PSTM and PSDM volumes, and interpreted these image volumes and correlated the interpretation results with the offshore borehole data. With the recoverable signal band of 30–960 Hz, I attained a vertical resolution of less than 1 m.
