Abstract (in english)
   We present a 3-D velocity model of the upper mantle beneath the northern and eastern parts of the Bohemian Massif (BM) based on data from passive seismic experiment BOHEMA II (May 2004-June 2005) consisted of 35 temporary stations complemented by data of permanent observatories. The resulting tomographic model, with a variance reduction of 84%, shows relatively small velocity variations, both in size and in amplitude. A small-size high velocity perturbation in the eastern part of the model can be related to the complex structure beneath the Sudetes/Moravo-Silesian unit contact. Similarly to results from the BOHEMA I experiment in the western BM, the presented model from BOHEMA II data confirms the north-southward thickening of the lithosphere.
