Eucrust_transD-ANT

Eucrust_transD-ANT is a new lithospheric-scale 3-D model of Western Europe derived from ambient noise tomography (ANT). This ANT makes use of vertical-component noise correlations computed between 950 permanent stations and 600 temporary stations from the AlpArray sea-land seismic network and the Cifalps and EASI linear arrays. 2-D group-velocity maps from 4 to 150 s are computed using a transdimensional (transD) Bayesian inversion of Rayleigh-wave traveltimes. Using a probabilistic approach, the local dispersion curves and their uncertainties are inverted at depth to derive a quasi-3-D model that is further refined using a linearized inversion. This resulting Vs model highlights strong along-strike variations of the lithospheric structure, particularly in the subduction complex between the European and Adriatic plates.
