Deep Crustal Magma‐Water Interaction During Oceanic Core Complex Termination of the Godzilla Megamullion in the Parece Vela Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Oceanic Core Complexes (OCCs) in back‐arc basins are not as thoroughly investigated, and their termination processes remain poorly understood. The Godzilla Megamullion is the largest known ceased OCC on Earth, yet magmatic and hydrothermal records from its termination are lacking.

Depositional History of the Namibian Mud Belt Reveals Late Holocene Weakening of the Benguela Coastal Current

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract We investigate late Holocene changes in the northern Benguela Upwelling System using a multi‐proxy approach on shallow shelf deposits from the Namibian mud belt. Three sediment cores characterized by organic carbon‐rich, anoxic, and partly gas‐bearing sediments were retrieved along a sampling transect at 23°S in August 2019.

Present‐Day Kinematics of Continental Greece and Balkans Revealed by Sentinel‐1 InSAR Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Balkan Peninsula hosts the highest seismic activity in Europe, marked by numerous Mw6+ earthquakes in diverse tectonic settings. Assessing tectonic surface deformation is crucial to understand the forces controlling kinematics and, ultimately, constraining geodynamic models. However, because measuring slow velocity rates (a few mm/yr) with

Porous and Permeable Crystalline Basement: Evidence for Large‐Scale Hydraulic Connectivity at Kivetty, Finland

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

Interseismic Strain Accumulation and Partitioning in Hispaniola From GNSS and InSAR

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We combine GNSS and InSAR observations to constrain the spatial distribution of strain across the northeastern Caribbean plate boundary, focusing on Hispaniola, to investigate strain partitioning and fault slip rates in an actively deforming tectonic setting with significant seismic hazard.

Why Does the Broken Hill Deposit Sit in Resistive Crust? Magnetotelluric Evidence for Metamorphic Decoupling of a World‐Class Mineral System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The spatial association between electrical conductors and ore deposits underpins the widespread use of magnetotellurics (MT) in mineral exploration, yet not all mineral systems preserve a diagnostic conductive signature. Here, we present a high‐resolution MT study of the region hosting the world‐class Broken Hill Pb‐Zn‐Ag deposit (NSW ...

Ship‐Based GNSS Tsunami Detection: Pilot Network Demonstration

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract We demonstrate the potential for ship‐based GNSS systems to contribute to tsunami warning. We built a pilot network of 10 ships—8 commercial and 2 research vessels—equipped with a tsunami detection package consisting of a geodetic‐grade GNSS antenna and receiver, and satellite internet communications.

Submarine Landslides Could Cause Wide‐Spread Tsunami Impact in the East Sea (Sea of Japan)

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The East Sea (Sea of Japan) is a seismically active back‐arc basin with a history of devastating tsunamis, yet regional hazard assessments and mitigation planning often overlook the tsunamigenic potential of submarine landslides. This study investigates the tsunami impact of large‐scale mass failures along the southwest (SW) margin of the East

First Direct Observations of Dilute Antarctic Turbidity Currents Associated With Dense Water Overflows

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Turbidity currents are increasingly recognised as a key mechanism for transporting sediment into the deep ocean, yet their structure, behavior, and long‐term impact in Antarctic submarine canyons remain poorly understood owing to a lack of direct observations.

Tracking Deep Mantle Melting on Mars Using Phobos Tides

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract We study the deep internal structure and rheological state of Mars by analyzing its response to tidal forces exerted by Phobos and by introducing a melt fraction in the mantle layers. Motivated by recent seismic evidence for a basal molten layer near the base of the Martian mantle, we explore the distribution of melt within the mantle and its ...
