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 ...

Non‐Perennial, Yet Predictable: Hierarchical Stream Activation Enables the Prediction of Channel Network Dynamics in Sporadically Monitored Catchments

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Predicting the dynamics of non‐perennial river networks is essential for hydrological modeling and water resource management. Yet, long‐term monitoring campaigns remains logistically challenging, particularly in remote and poorly accessible regions.

Exploring Potential Mechanisms for the Initiation of Solifluction Patterns

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract Hillslopes in arctic regions commonly display large‐scale features—known as solifluction patterns—that form due to the exceedingly slow downhill movement of frost‐heaved soil. Here we use a combination of remote sensing data, linear stability analysis, numerical modeling, and review of a wide range of literature to evaluate several working ...

Viscoelastic Strain, Viscous Rheology, and Behavior of Experimental Lava Flows

open access: yes, 2019
Basaltic pāhoehoe lava flows are prevalent throughout the terrestrial bodies of the solar system. This style of volcanism represents both a predominant resurfacing mechanism of planets and natural satellites and a natural hazard to populations living ...

Deep Origin and Shallow Launch for the Etna 122 B.C. Mafic Plinian Eruption

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Basaltic Plinian eruptions challenge our understanding of explosive volcanism. The 122 B.C. Plinian eruption of Etna ranks among the most powerful mafic explosive events known. Here, we combine volatile barometry of 122 B.C. from olivine‐hosted melt and fluid inclusions with comparative data from the sub‐Plinian Fall Stratified eruption at ...

Mastcam‐Z Spectrophotometric Properties of Materials at the Van Zyl Overlook, Jezero Crater

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract During Sols 63–65 of Mars 2020, Mastcam‐Z multispectral (442–1022 nm) images were acquired at Van Zyl Overlook (VZO), spanning phase angles from ∼0° to 150°, to model photometric parameters for seven surface units. These units included rocks, soils, regolith, and rover tracks near the Jezero landing site.

Geologically Recent Formation of Some Tesserae on Venus by Plains Deformation

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Tessera is a pervasively deformed terrain type on Venus generally interpreted as the oldest preserved material on the surface. Large expanses of this terrain type are typically elevated and have been hypothesized to be felsic, perhaps analogous to Earth's continents and even to date from an era with a more Earth‐like climate earlier in Venus ...
