Seismic Anisotropy Workshop

open access: yesEos, Transactions American Geophysical Union, 1987
P wave anisotropy, the direction dependence of P wave velocities, is widely recognized to exist in the crust and upper mantle. The anisotropic effects of layered media, of aligned crystals in ductile rock, and of aligned cracks in brittle rock have been observed or have been speculated to yield information on earth structure and geomechanical processes.

Wavelet‐Based Hurst Exponent Estimation

open access: yesWIREs Computational Statistics, Volume 18, Issue 3, September 2026.
The review explores how wavelet‐based methods for estimating the Hurst parameters have developed from their theoretical roots to real‐world applications in fields like biology, engineering, and telecommunications. The review aims to highlight key techniques, compare their strengths and limitations, and point out challenges that still need to be ...

Crustal Seismic Anisotropy in Shandong

open access: yesDEStech Transactions on Materials Science and Engineering, 2017
Based on the seismic data of near-field source from Shandong Seismic Network, the study obtained the shear-wave splitting parameters from multiple stations. The results show that dominant directions of polarizations of fast shear-waves reflect the spatial distribution characteristics of tectonic stress in this area, CHD and LIS stations show 2 dominant

The Significance of Inherited Crustal Thickening in Surface Uplift of Hangai Dome in Central Mongolia

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The Hangai Dome in central Mongolia represents one of the most prominent intracontinental uplifts, yet the relative contributions of crustal and mantle dynamics in sustaining its high topography remain unresolved. Here we jointly invert Rayleigh wave dispersion and receiver function data to constrain crustal and uppermost mantle structures ...

Dataset of Microstructural and Dynamic Mechanical Properties of Compacted Loess Modified by Calcium Oxalate Crystals: Implications for Geotechnical Engineering in Loess Regions

open access: yesGeoscience Data Journal, Volume 13, Issue 3, July 2026.
Dynamic torsional shear tests and SEM/PCAS analysis were combined to characterize calcium oxalate crystal‐modified compacted loess. The dataset connects OA concentration, damping‐ratio behaviour, pore‐structure evolution and Pearson correlations, supporting micro–macro interpretation of chemically modified loess.

ECOMAN: an open-source package for geodynamic and seismological modelling of mechanical anisotropy [PDF]

open access: yesSolid Earth
Mechanical anisotropy related to rock fabrics is a proxy for constraining the Earth's deformation patterns. However, the forward and inverse modelling of mechanical anisotropy in 3D large-scale domains has been traditionally hampered by the intensive ...

Anisotropic Biot Coefficient of Fractured Rocks Drives Failure Conditions in Pressurized Reservoirs

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present a theoretical framework to quantify the equivalent Biot coefficient tensor of fractured rock masses based on the properties of both the intact porous matrix and the fracture network. Our results show that the presence of dominant fracture sets produces an anisotropic equivalent Biot tensor, with larger values in the direction ...

Seismic Evidence for Slab Tearing Beneath the Indo‐Myanmar Subduction Zone

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Slab tearing has been increasingly recognized as a key geodynamic process influencing the evolution of the eastern Himalayan syntaxis. However, whether, where and how the subducted Indian slab beneath the Indo‐Myanmar subduction zone has been torn remains poorly constrained.
