Experimental observation of water saturation effects on shear wave splitting in synthetic rock with fractures aligned at oblique angles [PDF]
Fractured rocks are known to exhibit seismic anisotropy and shear wave splitting (SWS). SWS is commonly used for fractured rock characterization and has been shown to be sensitive to fluid type. The presence of partial liquid/gas saturation is also known

Fully nonlinear inversion of fundamental mode surface waves for a global crustal model [PDF]
We use neural networks to find 1-dimensional marginal probability density functions (pdfs) of global crustal parameters. The information content of the full posterior and prior pdfs can quantify the extent to which a parameter is constrained by the data.

Subsonic near-surface P-velocity and low S-velocity observations using propagator inversion [PDF]
Detailed knowledge of near-surface P- and S-wave velocities is important for processing and interpreting multicomponent land seismic data because (1) the entire wavefield passes through and is influenced by the near-surface soil conditions, (2) both ...

Shear wave velocity-based evaluation of liquefaction resistance of in-situ sand with aging effects
The shear wave velocity is one of the commonly used parameters to evaluate liquefaction resistance of sandy soils. In this study, based on the initial liquefaction criterion-based shear wave velocity characterization model (i.e., the "Zhou-Chen model ...

Effects of Particle Shape on the Shear Wave Velocity and Shear Modulus of 3D Printed Sand Analogs
Isolating the effects of individual particle properties (e.g. shape, size, mineralogy, surface roughness) on the mechanical behavior of naturally occurring coarse-grained soils is a significant challenge in experimental studies.

Complex anisotropy beneath the Peruvian flat slab from frequency-dependent, multiple-phase shear wave splitting analysis [PDF]
Flat or shallow subduction is a relatively widespread global occurrence, but the dynamics remain poorly understood. In particular, the interaction between flat slabs and the surrounding mantle flow has yet to be studied in detail.
