Abstract:
Geothermal exploration in sedimentary basin settings requires essentially seismic surveying to image the subsurface structure. Urban areas are favorable areas for geothermal development because the high demand on heat and electricity is accumulated especially in megacities. Reflection seismic surveys in megacities are however challenging due to seismic noise, infrastructural
issues and high population density. A vibroseismic pilot study was conducted at the former city airport Berlin-Tempelhof, basically located in the center of Germany’s capital city. Two major questions were addresses to this reflection seismic experiment: (I) Can vibroseis provide sufficient data quality despite the intensive background noise of a mega city, and (II) what is the subsurface
geological structure of Berlin focusing on depth and thickness of the Middle Triassic and Lower Permian as potential hydrothermal
reservoirs.
