BOHLEN 2 1 Fachrichtung Geophysik Freie Universität Berlin Malteserstr. 74-100 Haus D 12249 Berlin Germany 2 Institute of Geosciences Geophysics Kiel University Numerical modeling of seismic wave propagation in realistic (complex) media is an important tool used in earthquake and exploration seismology. Since the widely used finite-difference (FD) approaches are based on the wave equation without physical approximations the methods account not only for direct waves primary reflected waves and multiply reflected waves but also for surface waves head waves converted
