Summary
3D shear-wave velocity model of the Central Andes from ambient noise tomography. The model incorporates broadband seismic data from 20 seismic networks deployed incrementally in the Central Andes from 1994 May to 2012 August, to image the shear wave velocity structure of the South American Cordillera.
