The 3D underground seismic network is based at the GFZ German Research Center for Geosciences in Potsdam. It consists of the local 3D underground seismic research group, industry representatives and mining universities. The network has the aim to establish 3D underground seismics as a key technology for the safe construction and use of underground structures on the market. For this purpose, the previous know-how and the research development status are made available to the market as a service portfolio.
