Abstract: Modeling near-field ground motion is an important and useful tool of modern seismology. In our work we use a finite difference algorithm to compute near-field ground motions from a real moderate event with pre-existing slip distribution model. Lately, synthetic seismograms are quantitatively compared with observed waveforms from near-field seismic stations in order to justify created model. Furthermore, we independently changed several source parameters (rupture velocity, source dimension and geometry), and structure (velocity model) in order to evaluate their influence on the waveforms. For the comparison of seismograms we applied quantitative misfit criteria based on wavelet transform.
