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.
