Representing anisotropic subduction zones with isotropic velocity models: A characterization of the problem and some steps on a possible path forward [PDF]

, 2016
Despite the widely known fact that mantle flow in and around subduction zones produces the development of considerable seismic anisotropy, most P-wave tomography efforts still rely on the assumption of isotropy.

Exploring Electrical Resistivity Tomography (ERT) to Detect Soil Pipes: Theoretical Modeling and Field Experiments

Land Degradation &Development, Volume 37, Issue 3, Page 1126-1142, 15 February 2026.
ABSTRACT Soil erosion research remains critical for sustainable development as it impacts soil health through different erosive processes. Recent studies on soil piping highlight advancements in detecting surface features (using UAV); however, detecting underground pipes still remains challenging.

Crustal Seismic Anisotropy in Shandong

DEStech 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

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

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

Solid 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 ...

Crustal Structure of Laurentia and Peri‐Gondwanan Terranes Beneath Ireland and Britain and Comparison With Eastern North America

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Appalachian‐Caledonian orogen was built during the Paleozoic by accretion of peri‐Gondwanan terranes onto Laurentia, culminating in the formation of Pangea. During the Mesozoic, Pangea broke apart, displacing one section of the belt to eastern North America and another to northwestern Europe.

A Seismic Inversion Problem for an Anisotropic, Inhomogeneous Medium [PDF]

, 2002
In this report, we consider the propagation of seismic waves through a medium that can be subdivided into of two distinct parts. The upper part is assumed to be azimuthally symmetric, linearly nonuniform with increasing depth, and the velocity dependence

Testing Volcano Deformation Models Against 3D Seismic Reflection Imagery of Ancient Intrusions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Magma intrusion often drives uplift of the overburden and free surface. Analytical modeling of such surface uplift at active volcanoes allows us to estimate intrusion geometries and positions, as well as volume and pressure changes; these insights have proven critical to forecasting volcanic unrest and eruptions. However, it is rarely possible
