We perform the first, detailed S-to-P receiver function analysis to determine the
depth of the lithospheric thickness in the Eastern Alps, Carpathians, and the Pannonian
Basin. The Pannonian Basin hosts deep sedimentary depocentres superimposed on a complex
basement structure and it is surrounded by mountain belts. The geophysical data on
which investigated the lithospheric thickness was derived in the whole Pannonian Basin,
are more than 20 years old. The determination and compilation of a new dataset is
timely. This work is the first uniform and comprehensive S receiver function study
of the Alpine-Carpathian-Pannonian system. We present our detailed workflow from the
data download via quality controls to the calculations and interpretations of the
S receiver functions in this study.We use data from the temporary seismic networks,
the permanent stations of the Hungarian National Seismological network, as well as
the permanent seismological stations in neighboring countries for the time range between
0.1.01.2002 and 31.01.2022. Owing to the dense station coverage we can achieve so
far unprecedented resolution, altogether 389 seismological stations are used in this
study. This enables us to provide new, hitherto unknown information about the lithospheric
thickness of the region. We apply two different quality control procedures for the
downloaded waveforms and the calculated S receiver functions. S receiver functions
are determined by the iterative time domain deconvolution approach.We apply 1D and
2D migration of the S receiver function. We compare our result maps with map from
previous geophysical investigation. We show migrated Common Conversion Point cross-sections
beneath the Pannonian Basin and Carpathians, and the Eastern Alps–Pannonian Basin
transition zone. Furthermore, we would like to provide new information about lithospheric
thickness in the eastern part of the investigated region (e.g., Apuseni Mountains,
Eastern-, Southern-Carpathians, Moesian Platform and Transylvanian Plateau).Furthermore,
we jointly interpret the S receiver function results with the seismic tomography calculations
of the P and S wave
