Expertise

Seismic interferometry (Green’s function retrieval)

Research

My research interests include application of the seismic-interferometry method on different scales – from millimetres to hundreds of kilometres – for solving of practical problems. The method allows the retrieval of the seismic response between two receivers as if one of them were a virtual source. This allows us to extract information of the subsurface or of an object at places where otherwise this would not be possible due to the absence of active sources at those places.
At certain conditions, the result retrieved by seismic interferometry also contains non-physical reflections, what we call ghost reflections. When identified, we can use the ghost reflections to monitor layer-specific changes of the seismic velocity and quality factor in the subsurface or inside objects.
