EMC-Crustal_Thickness_Error Crustal thickness values within the western United States derived from receiver function observations

The model crustal thicknesses values are based on common conversion point (CCP) stacking of receiver functions calculated from data recorded by USArray stations and other permanent and temporary deployments in the western United States.

EMC-SPani 3D joint anisotropic compressional and shear wave velocity model of the whole mantle

SPani (Tesoniero et al., 2015) is a joint model of radially anisotropic P- and S-velocity variation of the whole mantle based on the inversion of fundamental Rayleigh and Love surface waves up to the sixth overtone and major P- and S-body wave phases.

EMC-SPani-Supplemental Supplemental information on Earth model SPani

SPani (Tesoniero et al., 2015) is a joint model of radially anisotropic P-􀀀 and S-velocity variation of the whole mantle based on the inversion of fundamental Rayleigh and Love surface waves up to the sixth overtone and major P- and S-􀀀body wave phases. P-􀀀 and S-􀀀sensitive data are coupled in the inversion by Rayleigh wave data and a mineral physics based regularization term on the relationship between S-􀀀 and P􀀀-velocity variation. This page contains supplemental information on this model’s resolution.
