Seismic imaging of geodynamic processes — •Stefan Buske, Stefan Lueth, Sergei Shapiro, Christof Sick, Peter Wigger, and Mi-Kyung Yoon — Institut fuer Geologische Wissenschaften, Freie Universitaet Berlin, Malteserstr. 74-100, 12249 Berlin

Active seismic soundings of the earth’s interior comprise the reconstruction of subsurface images from reflected and backscattered waves. The recorded wavefield carries information about the medium, i.e. its rock-physical parameters (velocity, density, etc.) as well as its structural inventory (geological interfaces, fault zones, etc.). This talk gives an overview about recent imaging methodologies and presents applications from different scales within the earth: the subduction of an oceanic plate below South America, a paleo continent collision in Germany, a salt pillow structure within a sedimentary basin, and a study for the prediction of rock conditions around a tunnel.
