Abstrakt (anglicky)
   West Bohemia/Vogtland is the area of an increased geodynamic activity manifested by numerous mineral springs and CO2 emissions located at intersection of faults. The seismicity is characterized by reoccurrence of intraplate earthquake swarms with local magnitude mostly less than 4. Knowledge of a detailed crustal structure is essential for all advanced studies of seismicity and focal parameters of the micro-earthquakes. We concentrate on velocity model and Moho depth retrieval using waveforms of local micro-earthquakes that occurred during the 2008 swarm and were observed at the WEBNET seismic network stations. The waveforms typically display dominant direct P and S waves followed by converted and reflected waves secondarily generated at shallow and deep subsurface structure. Apart from velocity structure and source-receiver geometry the waveforms are significantly affected by focal mechanisms of the earthquakes.
   Therefore, the waveforms are processed separately for clusters of earthquakes with similar mechanism.
