Abstract
Sealed urban environments, associated traffic, and subsurface supply lines are normally considered very challenging terrains for high resolution seismic subsurface structure imaging. If cost efficiency is also taken into account, seismic measurements in urban areas are often considered expensive. Recently, a combination of a small shear-wave vibrator and a shear- wave land streamer was tested in Hanover, Germany as a tool for structure determination in cities. After two weeks of seismic data acquisition, not only the used SH shear-wave reflection exploration set-up proved to allow a comparably fast and trouble-free measurement progress, but also the inherent advantages of sealed terrain with respect to the absence of surface waves and in terms of uniform coupling has become apparent.
