High-quality active seismic data are currently acquired in the vicinity of the San-Andreas-Fault-System within the EarthScope project SAFOD. Our proposal aims at processing and interpretation of these data sets using newly developed techniques in order to derive a high-resolution image of the subsurface. On one hand we want to employ Fresnel-Volume-Migration to two of these data sets for an improved and more detailed image of the internal structure of the fault system compared with already existing images. On the other hand we want to locate local earthquakes from the vicinity of the fault system using a new efficient procedure followed by a study of their relationship to the structural features of the fault system. In summary these investigations provide an important contributation to the understanding of the physical and chemical processes that control the motion and earthquake triggering at such an active plate boundary.
