Data Services Products: EMC-Cascade.ANT.Gao-Shen.2014 3D shear-wave velocity model of the Cascades from full-wave ambient noise tomography

Summary

Cascade.ANT.Gao-Shen.2014, Gao and Shen (2014), is based on a full-wave ambient noise tomographic method and the analysis of Rayleigh waves from ~1000 stations between 1995 to 2012, including the EarthScope USArray Transportable Array and many other permanent and flexible arrays.
