Fault‐Related Carbonates as Quaternary Seismotectonic and Paleoclimate Archives (Monte Marine Fault, Central Apennines)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Seismogenic faults shape continental landscapes, drive crustal deformation and influence fluid exchange between the lithosphere and atmosphere. Yet, quantitative links between fault activity, exhumation and near‐surface environmental evolution remain poorly understood. Here, structural (meso‐ and micro‐scale) investigations are integrated with

Mantle Transition Zone Constraints on Slab Penetration and Slab‐Edge Mantle Flow Beneath the Kamchatka Peninsula

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Numerous seismic studies have reported the absence of a resolvable subducted slab beneath parts of northern Kamchatka, though the mechanism for this anomaly remains debated. We utilize 1,696 P‐to‐S receiver functions to image the mantle transition zone (MTZ) beneath the Kamchatka Peninsula and surrounding areas. Beneath southwestern Kamchatka,

Earthquakes and the Metamorphic Sole of the Tinos Ophiolite, Cyclades, Greece

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract We analyze deformation fabrics, compositions of melts, metamorphic temperatures, and paleopiezometric data beneath the Tsiknias Thrust, Tinos, Greece, which formed part of the plate boundary that, in Late‐Cretaceous time, absorbed convergence between Africa and Europe associated with final closure of the Vardar Ocean.

Full Waveform Modeling of Bridgmanite Fabric‐Induced Seismic Discontinuities in the Mid‐Mantle: Implications for Double Underside Reflections Beneath Subduction Zones

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Mid‐mantle (660–2,000 km) seismic observations are commonly attributed to thermo‐chemical heterogeneities or phase transitions, yet many observed features remain difficult to reconcile with these mechanisms alone. It has been shown that the depth‐dependent behavior of bridgmanite deformation generates a strain‐induced seismic discontinuity ...

Statistics of Orientation of Nightside Auroral Arcs and Interplanetary Conditions

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract We present statistics and dependence on interplanetary conditions of the orientation of nightside auroral arcs in the equatorward part of the auroral oval. The results related to the arcs essentially represent the orientation and dynamics of the equatorial boundary of the nightside auroral oval.
