The region of West Bohemia is one of the most geodynamically active areas of Central Europe. The activity is characterized by many natural phenomena such as recurrent seismic swarms. The crustal structure of the region was subject of many geophysical investigations that revealed increased reflectivity of the lower crust. In this thesis, we adapt the multi-azimuthal approach for the detection of crustal discontinuities developed by Hrubcov'a et al. (2013). We apply the ap- proach on waveforms of the 2000 and 2008 swarms that occurred in the Nov'y Kos- tel focal area registered by several German stations. Analysis of the data of more distant German stations allowed expanding of the information about the depth and character of the crust/mantle transition in a broader area of the West Bo- hemia region. The results show a thickening of the zone in Germany with in- creasing distance from the epicentral area. Such findings are in agreement with previous active and passive seismic experiments.
