Investigation of the 3-D subsurface structure of the Lausitz region and characterization of the ambient seismic noise | DZA
As part of the establishment of the German Center for Astrophysics DZA, a new large research center, it is planned to set-up an underground research laboratory, the “Low Seismic Lab”. To this end, we are conducting research in the Lausitz-granite (Lusatia) together with partners.
Within this project, we use passive seismic methods that make use of the wave fields of the ambient noise to resolve the 3-D subsurface structure in the region (ambient noise tomography). In contrast to classical active seismic methods, these novel passive methods have a very small environmental footprint because they only use the noise present in the earth, for example caused by ocean waves, wind or motor vehicles, and no controlled sources such as explosions or vibroseis signals have to be detected. The data to be analyzed will be recorded using several temporary seismic networks that we will install in the region in 2024 and 2025.
In addition, the data will be used to characterize the seismic noise in terms of space and time.
