Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract The Cenozoic topographic growth of the Iranian Plateau, situated at the Arabia‐Eurasia collision front, provides insights into continental collision dynamics. However, the relative contributions of tectonic shortening versus deep mantle processes to crustal thickening remain debated because systematic quantitative constraints on paleo‐crustal ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract The diverse volcanic activity in the Alaska Peninsula section of the Alaska‐Aleutian subduction zone is presumably caused by substantial variations in mantle wedge melting or trans‐crustal processes beneath the arc. In this study, we investigate sub‐arc melting beneath the Alaska Peninsula by measuring P‐wave attenuation, as attenuation is ...

Temporal Changes in the Earth's Outer Core From Nuclear‐Test PKP Waves
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract We investigate temporal changes in P‐wave velocity in the outer core using short‐period PKP waves generated by underground nuclear tests conducted in French Polynesia and recorded at seismic station BRVK in Kazakhstan. The observed first arriving PKP phase cannot be explained by ray theory.

Dynamic Evolution of Forearc Subsidence Controlled by Slab Geometry
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Several subduction zones worldwide present an enigmatic forearc topography and strain characterized by extension at a forearc ridge near the trench and shortening within a forearc valley located between the ridge and the magmatic arc. The development of this topography has been linked to progressive slab steepening, while strain patterns ...

Geometric Moment Modulated and Maximum Entropy Informed Earthquake + Afterslip Sequences
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Synthetic earthquake sequences may be of interest for comparisons with seismicity and afterslip evolution from instrumental observations and deeper time paleoseismic event histories, as well as for forecasting purposes. Here, we describe a constructed method, independent of continuum mechanics, for generating long‐duration earthquake and ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract The kinematics and progressive evolution of Riedel shear zones have been extensively studied, yet the factors controlling their distinct evolutionary styles in natural settings remain debated. Understanding such fracture network architecture has great implications, such as predicting subsurface fluid flow and assessing seismic hazards.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract The geometry and distribution of igneous intrusions, which define melt source locations and record syn‐emplacement stress conditions, are essential for understanding tectonic and magmatic processes associated with crustal extension. However, in back‐arc settings along continental margins, structural constraints on these features remain poorly ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract We present a comprehensive seismic characterization of the gas hydrate system in the outer continental shelf of the Mackenzie Trough, Canadian Beaufort Sea, based on recently acquired multichannel seismic (MCS) data, P‐wave velocity modeling, and 3D thermal modeling. We identified high‐amplitude, reverse‐polarity Bottom‐Simulating Reflections (

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Oceanic transform faults frequently generate moderate‐sized earthquakes in quasi‐periodic cycles, offering attractive cases for studying earthquake physics. However, characterizing these remote events remains challenging due to the scarcity of local seismic data.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.Abstract Fjords are globally significant sedimentary archives that record the relationship between glacial, tectonic, and marine processes. Fiordland, on the southwest coast of New Zealand, hosts one of the most extensive temperate fjord provinces in the Southern Hemisphere, yet its postglacial evolution has remained poorly constrained.
