Seismics

The main topic of our research is the development of innovative seismic methods to image the subsurface. We use seismic methods to study geodynamic structures and processes. Moreover, we investigate geo-reservoirs.
Seismic methods allow insight into deeper parts of the Earth which are not directly accessible. These methods use seismics waves from artificial sources or natural sources. The analysis yield images of the subsurface which allow inferences about the Earth's structures, material properties and processes. Moreover, also the sources itself can be studied with seismic observations (focal parameters, locations).

Development & Methods
	One focus of our research is the development of new seismic methods to image the subsurface including methods for integrated interpretation. Currently, we are working on the following topics: Lithological classification, imaging of vertical structures, migration and array methods, localizing non-volcanic tremor, analysis of ambient noise and surface waves.                        ...more
Investigation of geodynamic processes
	We use reflection and refractions seismic methods at different scales as well as earthquake observations and ambient noise to investigate geodynamic key processes. Particularly, we investigate processes at continental shear zones, active and passive continental margins and plumes. For this research we conduct large field experiments.                                       ...more
Investigation of geo-reservoires
	Active and passive seismic methods are used in our group to study unconventional reservoirs (gas hydrates, gas shales, geothermal). The exploration of such resources requires knowledge of the seismic properties. We carried out crosshole tomography in gas hydrates and found unusual seismic characteristics. Gas shales are studied using core analysis, near-surface tomography, and seismic reflection processing. Geothermal exploration projects were carried out in the Central European basin and in Island. A new project started now to develop geothermal energy in Indonesia.                                                                    ...more
