Upper Crustal Structure of the West Bohemia/Vogtland Swarm Region Reflected by Local Seismic Signals

We study seismicity of the West Bohemia seismic swarm area. The area is covered by high quality seismic stations of WEBNET network. In seismic records of local events we can identify not only direct P- and S- wave arrivals but also other waves. Seismograms contain many reflected, refracted or split phases, which reflects complex geological as well as tectonic settings of the region. We try to identify these phases in seismograms and their origin at structural interfaces. Results of such investigation will improve our knowledge about upper crustal structure of the swarm area.
