From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence

open access: yesEarth and Space Science, Volume 13, Issue 11, November 2026.
Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

A New Amphibious Earthquake Catalog for the Alaska Peninsula: Training, Testing, and Applying Machine Learning Earthquake Picking in Offshore and Amphibious Environments

open access: yesEarth and Space Science, Volume 13, Issue 11, November 2026.
Abstract The dual seismological developments of large‐scale offshore observational networks and high‐quality machine‐learning earthquake detection and picking allow unprecedented seismicity detection in high hazard subduction zones. We develop a high resolution machine learning enhanced seismicity catalog for the Alaska Peninsula stretch of the Alaska ...

Geochemical Characteristics of Metasediment—Rich Lower Continental Crust: Insights From the Ivrea‐Verbano Zone (DIVE Drilling Project, ICDP Expedition 5071, Val d’Ossola, Italy)

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract Whole‐rock geochemical data from two drill cores obtained through the ICDP (International Continental Scientific Drilling Program) funded Drilling the Ivrea‐Verbano Zone (IVZ) (DIVE) project: 5071_1_B (Ornavasso) and 5071_1_A (Megolo), provide new insights into the composition of the lower continental crust (LCC) in the IVZ. Borehole 5071_1_B (

The Search For Pulsar Wind Nebulae in the Very High Energy Gamma-ray Regime [PDF]

open access: yes, 2010
The aim of this Thesis is to study the development of pulsar wind nebulae in the TeV regime and in doing so uncover more sources which have as yet not been observed at these wavelengths.

A Late Cretaceous Aborted Spreading Center in the Northern Arabian Sea Recorded by the Laxmi Basin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 11, November 2026.
Abstract The Laxmi Basin (LB), a marginal depression, is a prominent geomorphic feature in the northern Arabian Sea. Understanding how the basin formed has important implications for the India–Seychelles breakup and the evolution of the western Indian Ocean.

The Spatial Localization of Storm‐Time ULF Waves Due To Plasmaspheric Plumes

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The generation and propagation of Ultra Low Frequency (ULF) waves are intrinsically coupled to the cold plasma population in the terrestrial magnetosphere. During geomagnetic storms, extreme reconfigurations of the cold plasma create a complex and dynamic system that drastically modifies this coupling.

Suprathermal Electron Acceleration Comparison of the Venusian and Terrestrial Bow Shocks

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract We study suprathermal electron acceleration at the Venusian bow shock using the Parker Solar Probe gravity assists and the Venus Express spacecraft mission. The acceleration is classified by measuring the maximum energy and the power‐law spectral slope (index) of the electron phase space density immediately downstream of the shocks for ...

Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.

Is Magnetic Reconnection Dominantly Spatially or Temporally Variable: First Results From TRACERS

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The Tandem Reconnection And Cusp Electrodynamics Reconnaissance Satellites (TRACERS) small explorer mission was designed to: Determine whether magnetopause reconnection is primarily spatially or temporally variable for a range of solar wind conditions. Observations from the Analyzers for Cusp Ions (ACIs) on the two TRACERS spacecrafts are used

ELFIN Statistics of Electron Strong Diffusion in the Inner Magnetosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract Pitch‐angle diffusion of trapped electrons driven by whistler‐mode and EMIC waves and by field‐line curvature scattering (FLCS) plays an important role in energetic and relativistic electron loss from the inner magnetosphere. The strong diffusion regime, characterized by a nearly full loss cone, rarely occurs, but is expected to account for a ...
