A Hybrid Framework Combining Physical and Data‐Driven Models for Predicting the Timing of Fault Instability

open access: yesEarth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Reliable prediction of earthquakes and rock mass failure has long been hampered by a fundamental trade‐off: achieving both a long warning window and high prediction accuracy. Physical models, such as the failure forecast method (FFM) based on the time‐reversed Omori law, can provide longer warning windows but are sensitive to data noise and ...

From the Dawn of Neutrino Astronomy to a New View of the Extreme Universe

open access: yesPhysical Review X
Over the past decade, neutrino astronomy has emerged as a new window into the extreme and hidden Universe. Current-generation experiments have detected high-energy neutrinos of astrophysical origin and identified the first sources, opening the field to ...

Multiscale energy conversion and transfer in the middle atmosphere during the 2023 sudden stratospheric warming

open access: yesEarth and Planetary Physics
To understand energy transfer during sudden stratospheric warming (SSW) events in the middle atmosphere, the 2023 SSW is studied by using the analysis tools of the multiscale window transform (MWT) and MWT-based localized energetics analysis and theory ...

Insights Into Microscale Biomineralization in Deep‐Sea Callogorgia Coral via Halogen Banding

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Halogen incorporation into coral carbonate skeletons serves as a valuable proxy for reconstructing paleoenvironments. However, the underlying mechanisms remain poorly understood. This study employed femtosecond laser ablation‐inductively coupled plasma time‐of‐flight mass spectrometry (fs‐LA‐ICP‐TOFMS) to perform multi‐elemental (I, Br, P, Ca,

Comment on “Parameterizations of Clinopyroxene—Melt Trace Element Partition Coefficients” by Bédard, J. H. (2014)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract A better understanding of how trace element partition coefficients vary with melt and mineral composition, temperature, pressure, oxygen fugacity and fluid composition is essential to geochemical modeling of magmatic rocks. The Nernst partition coefficient D is the ratio of the concentration (by weight) of a trace element in a solid phase ...

Pattern Formation in Rocks

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract This commentary concerns a two‐part paper by Regenauer‐Lieb et al. (2026a, 2026b) on pattern formation in deforming porous rocks. The theory developed in part I (https://doi.org/10.1029/2025GC012710) uses the general idea of Turing's reaction‐diffusion model of morphogenesis based on interactions between two types of diffusible chemical ...

Can Solar Cyclic Variability Mimic Extreme Solar Particle (Miyake) Events in Radiocarbon?

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Rapid, strong enhancements in Δ14 ${{\Delta }}^{14}$C in the Earth's atmosphere, known as Miyake events, rarely occurred over the past millennia, pointing to major radiation storms affecting Earth. They are produced by extreme solar particle events (ESPEs) and are separated by an order‐of‐magnitude gap in the strength from directly observed ...

Neural Network Imputation of the Pitch‐Angle‐Resolved Medium‐Energy Electron Flux Data in LEO

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract Pitch‐angle‐resolved electron flux data are crucial for investigating variations in electron flux within the magnetosphere and the underlying mechanisms, such as radial diffusion and wave‐particle interactions. The Medium‐Energy Electron Detector (MEED) onboard the Fengyun‐3E (FY‐3E) satellite in Low Earth Orbit (LEO) provides 18‐directional ...

Michigan Geospace Model With Ensemble Forecasting and Particle Filtering: Modeling the May 2024 Extreme Storm

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract This paper introduces an updated version of the University of Michigan Geospace model. The Geospace model has been used for operational forecasting at the Space Weather Modeling Center of the National Oceanic and Atmospheric Agency since 2016 with regular updates. The current operational version, Geospace V2, was launched in 2021 and is driven
