VS structure of the crust and upper mantle in the Balkan Peninsula region

TL;DR

This paper presents a detailed 3D shear-wave velocity model of the Balkan Peninsula's crust and upper mantle up to 350 km depth, using advanced seismic imaging techniques to improve previous regional models.

Contribution

It introduces an upgraded and refined 3D shear-wave velocity model for the Balkan region, integrating multiple seismic methods and extending previous studies.

Findings

Enhanced resolution of the crust and upper mantle structure.

Improved seismic velocity models compared to earlier studies.

Extended depth coverage up to 350 km.

Abstract

This study defines a 3D shear-wave velocity model to the depth of about 350 km in the region of Balkan Peninsula by application of several methods and tools: collection of surface-wave dispersion measurements; tomography on a grid sized 1 degree by 1 degree; non-linear inversion of dispersion relations; local smoothing optimization; and juxtaposition of representative cellular models. This study upgrades, refines and extends the results obtained for the region by Raykova and Panza (2006), Raykova and Nikolova (2007), Panza et al. (2007) and Brandmayr et al. (2010).
