Constraining the Permeability and Outer‐Rise Hydration at the Central America Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Subduction zones are important drivers of Earth's geochemical evolution; the presence of water within the subduction system has substantial implications for geohazards, including the style of seismicity and the volume of magma generated at arc volcanoes.

Finite element models of spontaneous subduction initiation: preliminary results [PDF]

Subduction is a key process in Earth's plate tectonics that drives plate movement through slab pull. Despite its significance, the mechanisms behind subduction zone initiation (SZI) are not fully understood, and various hypotheses have been proposed and ...

Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.

Crustal Thickness Inversion From Magmatic Geochemistry Reveals Spatiotemporal Evolution and Two‐Stage Uplift of the Iranian Plateau

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 ...

Seismic Constraints on Igneous Intrusions and Fluid/Gas Distribution in a Continental Back‐Arc System: Evidence From the Yaeyama Rift in the Southern Okinawa Trough

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 ...
