The Pannonian Basin is located in Central-Europe surrounded by the Alpine, Carpathian,
and Dinarides mountain ranges. This is a back-arc basin characterized by shallow Moho
depth, updoming mantle and high heat flow. In this study, we present the results of
the Rayleigh wave based ambient noise tomography to investigate the velocity structure
of the Carpathian-Pannonian region. For the ambient noise measurements, we collected
the continuous waveform data from more than 1280 seismological stations from the broader
Central-Eastern European region. This dataset embraces all the permanent and the temporary
(AlpArray, PASSEQ, CBP, SCP) stations from the 9-degree radius of the Pannonian Basin
which were operating between the time period between 2005 and 2018. All the possible
vertical component noise cross-correlation functions were calculated and all phase
velocity curves were determined in the 5-80 s period range using an automated measuring
algorithm. The collected dispersion measurements were then used to create tomographic
images that are characterized by similar velocity anomalies in amplitude, pattern
and location that are consistent with the well-known tectonic and geologic structure
of the research area and are comparable to previous tomographic models published in
the literature.
