Annotation
We apply a traditional method of surface wave tomography as a new approach to investigate the uppermost crust velocities in the Western Bohemia region (Czech Republic). It enables us to look for velocity distribution in a small scale of tens of kilometers. We measure Rayleigh wave group velocity dispersion curves in a period range 0.25 – 2.0 s along paths crossing the region of interest. We compute 2-D tomography maps of group velocity distribution in the region. We discuss the velocity distribution with respect to results of former studies.
