In this thesis, I advance the methodology of ambient noise tomography and at the same time study the crustal and upper mantle structures of New Zealand and the western United States. a novel inversion technique that I call eikonal tomography possesses many advantages over the traditional straight ray inversion method and can be used to constrain both isotropic and anisotropic structures and their uncertainties.
