Abstract
The surface wave tomography from ambient seismic noise recorded at stations in Western Europe (WE) and on the East European Platform (EEP) revealed the structure of the crust and upper mantle in the transitional zone from the Precambrian platform to the younger geological units in Western Europe. The Tornquist-Teisseyre Line separating these structures is clearly traced as a transition zone from the high velocities beneath EEP to the low velocities beneath WE in the crust and upper mantle, which extends to a depth of 150–170 km. Below 200 km the relationship between the velocities beneath EEP and WE becomes the opposite. A similar relationship between the velocities in the upper mantle down to a depth of 300 km is observed on the southern boundary, where EEP borders on the northern segment of the Alpine-Himalayan seismic belt.
