Shear-wave splitting provides insight into geodynamic processes such as lithospheric
deformation and upper mantle flow. This study presents shear wave splitting parameters …

We apply Pn tomography beneath the entire USArray footprint to image uppermost mantle
velocity structure and anisotropy, as well as crustal thickness constraints, beneath the United …

We develop a regional seismic travel-time (RSTT) model and method for use in routine
seismic analysis. The model parameterization is a global tessellation of nodes with a …

The northeastern margin of Tibet is of key importance in understanding the uplift and
expansion of Tibetan Plateau. In this research, we perform Rayleigh wave tomography from …

We present a new high‐resolution model of P‐wave anisotropic tomography of the
uppermost mantle beneath NE Asia obtained by inverting 88,303 high‐quality manually …

Variations in the seismic velocity structure of the Himalayan collision zone include significant
differences between its north and south portions, with transitions in physical properties …

We applied a nonlinear teleseismic tomography algorithm to explore the 3-D structure of the
upper mantle beneath the Arabia–Eurasia continental collision zone in western Iran. An …

Tomographic inversion with interstation Pn differential traveltime data provides a reliable
velocity image of the uppermost mantle across the Longmenshan Fault Belt, which borders …

We present new maps of Lg coda Q (Qo and its frequency dependence) at 1‐Hz that cover
virtually all of Eurasia. Qo is relatively high, up to 650 or more, in the east European …

USArray has now provided several years of high‐quality seismic data and improved ray
coverage for much of the western United States, which will enable increased resolution for …
