Mantle flow and lithosphere-asthenosphere coupling beneath the southwestern edge of the North American craton: constraints from shear-wave splitting measurements
<p>"High-quality broadband seismic data recorded by the USArray and other stations in the southwestern United States provide a unique opportunity to test different models of anisotropy-forming mechanisms in the vicinity of a cratonic edge. Systematic spatial variations of anisotropic …

Seismic anisotropy and mantle dynamics beneath the central and western United States
… and the recent availability of high-quality broadband seismic data from the USArray and other seismic stations in the central and western United States (CWUS) provide a distinct opportunity to test different anisotropy-forming mechanisms. For the first part of the study, a total of 4138 pairs …

Crustal structure and evolution beneath the Colorado Plateau and the southern basin and range province
… functions recorded at 72 USArray and other broadband seismic stations placed on the Colorado Plateau and the SBRP in Arizona revealed systematic spatial variations in crustal Vp/Vs, crustal thickness and amplitude of P-to-S converted phases. Our results reveal that the BRP is characterized …

Ambient seismic noise tomography of the southern United States and seismic inversion with dictionary learning using unsupervised machine learning.
Seismic tomography and inversion are well-established methods to understand deep subsurface structures. These techniques are particularly effective in delineating complex crustal architectures, which often deviate from simplified textbook models. High-resolution seismic tomography enables the …
