We perform receiver function analysis to determine a detailed
map of the crust-mantle boundary and the crustal
velocity structure of the transition zone between the Eastern
Alps and the Carpathian Basin. We use data from the
AlpArray temporary seismic network, the permanent stations of
the Hungarian National Seismological network,
stations of a private network operated by Georisk Ltd. as well
as permanent seismological stations in the neighbouring
countries for the time period between 1996 and 2017.
Altogether some 200 seismological stations are used
in the analysis. Owing to the dense station coverage we can
achieve so far unprecedented resolution, thus extending
our previous work on the region. We apply three different
quality assurance procedures for the waveforms and
the obtained receiver functions. Receiver functions are
calculated by the iterative time domain deconvolution
approach.
We present the quality controlled P receiver functions (radial
and transversal component) and preliminary
results for the Moho map obtained by H-K analysis. We also
compare our results to previous active and passive
seismological results in terms of Moho depth and crustal
velocities.
