Widespread Impact‐Induced Crustal Permeability on the Early Earth

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract The early Earth (i.e., Archean and Hadean Eons, 2.5–4.0 and 4.0–4.5 Ga, respectively) experienced frequent cosmic bombardment. Impacts have been shown to stimulate crustal alteration, for instance via hydrothermal systems active for up to millions of years post‐impact.

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

Redistribution of Basal Forces and Shielding Model for Seismic Signals of Debris Flows Over Loose Thin‐Layer Sediments

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Debris flows over riverbeds generate intense basal force fluctuations that radiate seismic signals, offering a key tool for remotely monitoring their dynamics. In steep, highly erosive mountainous channels, bedrock is often covered by a thin layer of loose sediments, which significantly reduce seismic energy.

Impacts of E‐Region Neutral Wind Shear on Equatorial Plasma Bubbles: SAMI3 Simulations Including Metal Ions

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The vertical shear of horizontal neutral winds plays an important role in forming dense metallic layers in the E region. Previous studies suggest that metal ion layers may inhibit equatorial plasma bubble (EPB) development by enhancing E‐region Pedersen conductivity.

On the Formation of the E Region Layers at Low Altitudes—Theory

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract An analysis of E region ion layer formation is presented, including the effects of a non‐dipole geomagnetic field and gravity on vertical ion drifts, with a particular focus on E region layers at lower altitudes (ELLAs). For nonzero magnetic declination, meridional winds can have an effect similar to those of zonal winds.
