Data Services Products: EMC-EAV09 3D shear-wave velocity model of western Eurasia, Arabia, and northern Africa from a joint inversion for multiple data sets

Summary

EAV09 Chang et al. (2010) is a 3D shear-wave velocity model for western Eurasia, Arabia, and northern Africa based on multiple data sets including regional S and Rayleigh waveform fits, fundamental-mode Rayleigh-wave group velocities, teleseismic S and SKS arrival times, and independent Moho constraints.
