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

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).
