Slab Gap‐Related Intraplate Magmatism as a Proxy of Maximum Flat Slab Extent in Patagonia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Establishing the frontal extent of ancient flat subduction events from the geologic record can be challenging. This difficulty arises because magmatic activity in the arc typically ceases during complete slab flattening, and other meaningful proxies are usually absent. To address this issue, we examine early Paleocene intraplate magmatic units

Nature of the Crust in the Superdeep Bengal Basin Using Teleseismic P Waves

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Bengal Basin is a sedimentary basin in the northeast region of the Indian subcontinent. It lies between the Indian Shield and the Indo‐Burma Ranges, where the India plate is obliquely subducting under the Burma microplate. Multiple interpretations of the nature of the crust here have been proposed.

Dynamic earthquake ruptures on multiscale fault and fracture networks

, 2018
Les zones de faille naturelles présentent une complexité structurelle à différentes échelles. Cette complexité géométrique impacte la dynamique de la rupture, la propagation des ondes sismiques ainsi que le bilan énergétique lors des tremblements de terre. Dans cette étude, afin de pouvoir modéliser des ruptures sismiques le long de failles à géométrie

Influence of the Loading Stiffness on Sheared Granular Fault Gouge, and Applicability to Slip‐Weakening Theory

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Tectonic faults can slip in a spectrum of fault slip behaviors, from aseismic slip and slow ruptures to elasto‐dynamic earthquakes. Following frictional theory, laboratory experiments have shown that the basic ingredient that may control this transition is the interaction between the fault stiffness and the surrounding elastic medium.

A Random Walker Algorithm for Plate Boundary Detection in Spherical Mantle Convection Models and Global Geophysical Data Sets: Application to Euler Vector Determination

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract As spherical shell mantle convection models become increasingly commonplace, understanding how plates are generated has raised the issue of how to recognize whether rigid plates are present in model output. Tectonocists have long recognized that intraplate regions are not rigid without exception.

Poroelastic Bulk Controls on Shear Localization in Fault Gouge During Earthquake Rupture: Insights From a Hybrid Numerical Framework

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Seismic ruptures that extend over kilometers along faults originate in shear zones only millimeters thick. We present a hybrid numerical framework coupling the spectral boundary integral method (SBIM) for the poroelastic bulk with a staggered‐grid finite difference method (FDM) for the fault gouge.
