Improved Approaches for 3D Gravity and Gradient Imaging Based on Potential Field Separation: Application to the Magma Chamber in Wudalianchi Volcanic Field, Northeastern China

Remote Sensing
The gravity and gradient anomalies contain valuable information about the underground geological structures at various depths. Deep and shallow buried source bodies are able to be identified through multi-scale field separation processes, and visual ...

Integrated Geophysical Imaging Reveals the Origin and Pathways of Mantle‐Derived CO2 Beneath the Tangra Yumco Rift, Central Tibet

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Tangra Yumco Rift (TYR) in central Tibet is a key window for crust–mantle interactions during extension. We performed high‐resolution crust‐mantle imaging using receiver function analysis, 1‐D nonlinear S‐wave velocity inversion, and tomoDD tomography, revealing a vertical Crust–Mantle Degassing System (CMDS) bounded by the Zhala (ZF) and ...

Thermodynamics‐Based THMC Model for Solute Transport in Sorptive Fractured Rock: Coupling Multi‐Phase Flow, Heat, and Deformation

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Fractured porous rocks host a complex interplay of heat, fluids, deformation, and chemical reactions, yet their combined influence on solute transport remains poorly resolved. Here we show that these processes are more tightly coupled than previously assumed.

Emergence of Uncompensable Heat Stress During Monsoon Season in India

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Uncompensable heat stress (UHS), characterized by the loss of homeostasis due to excessive environmental thermal loading, causes substantial heat‐related health risks in India. However, the spatial and seasonal heterogeneity, as well as temporal changes of UHS in India remain poorly understood.

Report of the panel on volcanology, section 4

, 1991
Two primary goals are identified as focal to NASA's research efforts in volcanology during the 1990s: to understand the eruption of lavas, gases, and aerosols from volcanoes, the dispersal of these materials on the Earth's surface and through the ...

VarPy: A Python library for volcanology and rock physics data analysis [PDF]

, 2014
VarPy is an open-source toolbox which provides a Python framework for analysing volcanology and rock physics data. It provides several functions, which allow users to define their own workflows to develop models, analyses and visualisations. The goal of the VarPy library is to accelerate the uptake of computational methods by researchers in volcanology

Metamorphic Dehydration, Fluid Pressure, and the Frictional‐Viscous Transition Along Subduction Megathrusts: Case Study in Cascadia and Implications for Slow Earthquakes

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).

Magmatic Memories: Eldfell, 1973

Volcanica
2023 marked the 50th anniversary of the 1973 Eldfell eruption on the island of Heimaey, Iceland. The eruption began unexpectedly at 1:50 a.m. on the 23rd of January 1973, creating a need to evacuate all 5300 residents to the Icelandic mainland by fishing

Integrating Olivine Diffusion Chronometry With Monitoring Data to Decipher the Magma Dynamics at the Submarine Fani Maoré Volcano

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Monitoring data are critical for understanding volcanic unrest and eruption, but they often lack the ability to constrain the pre‐eruptive magma processes. As such, an increasing number of studies couple monitoring data with petrological tools to obtain insights into the causes and durations of magmatic processes. The 2018–2020 eruption of the
