Seismicity to the South of the Louisville Ridge‐Tonga Trench Collision Zone: New Insight Into Processes Controlling Seismic Gaps and Subduction Erosion

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract The Louisville seismic gap associated with the subduction of the Louisville Ridge (LR) along the Tonga‐Kermadec trench is a globally prominent feature. Due to the lack of near‐field seismic monitoring, the earthquake potential and seismic behavior in this region have long been an enigma.

Hydration and dehydration of CM chondrites revealed by X‐ray diffraction combined with textural observations and compositional data

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 5, Page 1194-1215, May 2025.
Abstract The in‐plane rotation method is used to obtain X‐ray random diffraction (XRD) patterns of polished thin sections of 10 CM chondrites. The samples include five intermediately altered CM chondrites with subtypes 2.6–2.3, two heavily altered CM chondrites with subtype 2.0 and three with secondary heating after hydration (Y 980036, Y 980051, and ...

Downdip Variations in Megathrust Seismogenic Behavior in the Japan Trench Subduction Zone Affected by Mantle Wedge Serpentinite

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract It is important to seek geological context for the geophysically observed downdip segmentation of seismogenic behavior of subduction megathrusts. Here we focus on how mantle wedge serpentinite may affect megathrust seismogenesis at Japan Trench—an end‐member cold subduction zone.

The Global Health Dimensions of Asbestos and Asbestos-Related Diseases

open access: yesAnnals of Global Health, 2016
The Collegium Ramazzini (CR) reaffirms its long-standing position that responsible public health action is to ban all extraction and use of asbestos, including chrysotile. This current statement updates earlier statements by the CR with a focus on global

Comparative Properties of Saponitic Fault Gouge and Serpentinite Muds Cored From Mud Volcanoes of the Mariana Subduction Zone

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract We obtained 12 core samples for physical and chemical characterization from three serpentinite mud volcanoes (Yinazao, Asùt Tesoru, and Fantangisña) located on the forearc of the Mariana subduction system, that were drilled during International Ocean Discovery Program Expedition 366. Two samples from the Fantangisña mud volcano are interpreted

Magnetization of Ultramafic Rocks in the Troodos Ophiolite: Implications for Ridge Axis Serpentinization and Ophiolite Emplacement

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Ultramafic rocks exposed in ophiolites are almost always serpentinized, but it is unclear whether the serpentinization occurs during lithospheric formation or subsequent ophiolite emplacement. The Troodos ophiolite offers an opportunity to discriminate between different serpentinization processes, incorporating rock magnetism, paleomagnetism ...

Remagnetization of Serpentinite During Deformation: Evidence From a Fossil Oceanic Transform Fault Zone of the Troodos Ophiolite

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract Serpentinization and associated chemical remagnetization of ultramafic rocks are common in tectonically active oceanic zones such as transform zones; however, it remains unclear how chemical remagnetization occurs during the deformation of serpentinite.
