Internal Structure of the Mantle Transition Zone Beneath the Contiguous U.S.: Insights From the 520‐km Discontinuity Revealed by Ambient Noise Correlations

Abstract We investigate the internal structure of the Mantle Transition Zone (MTZ) beneath the contiguous U.S. by mapping the depth of the 520‐km discontinuity (d520) and the relative amplitude of seismic phases associated with the 520‐, 410‐, and 660‐km discontinuities. Specifically, we analyze sho...
