Seismic Constraints on Temperature, Partial Melt, and Lithosphere‐Asthenosphere Dynamics in the Southwestern United States

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The southwestern United States hosts well‐documented and dramatic variations in topography, seismicity, heat flow, magmatism, and seismic velocity structure. This region offers opportunities to investigate how processes such as temperature and partial melt are related to the Lithosphere‐Asthenosphere Boundary (LAB), and how they ultimately ...

Numerical Simulations of Sulfate Formation via the Diffusive Reaction Between Ca2+ in Volcanic Ash and SO2 Gas: Evaluation of SO2 Losses From Eruption Clouds During the 1991 Pinatubo Eruption

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Volcanic ash formed during explosive volcanism reacts with SO2 gas molecules in volcanic conduits and eruption clouds, resulting in the formation of CaSO4. When ash is removed from the eruption cloud, the SO2 gas molecule is scavenged from the eruption cloud. The CaSO4 growth is rate‐limited by Ca2+ diffusion at high temperatures.

Seismo‐Acoustic Evidence for Meteoric Water Modulation of Hydrothermal Fluid Discharge

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Deciphering the signal of external processes on active hydrothermal dynamics represents a critical challenge in understanding volcanic unrest. At the Pisciarelli hydrothermal site, located within the densely populated Campi Flegrei caldera (Italy), we investigate the role of meteoric water influx in modulating shallow hydrothermal fluid ...

Stress and Strain in Magma‐Mush Reservoirs: Implications for Reservoir Failure and Magma Propagation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Investigating the mechanical stability and failure of magma reservoirs following magma supply is critical for volcanic hazard assessment. While magma reservoirs were traditionally modeled as melt‐filled cavities, they are now more often described as crystal mushes where melt flows and is stored in porous networks.

Integrating GNSS and Hydrological Data to Understand Seasonal Microseismicity at La Soufrière de Guadeloupe

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract La Soufrière de Guadeloupe volcano exhibits microseismic activity dominated by volcano‐tectonic repeaters, mainly occurring in swarms clustered in a sub‐vertical conduit beneath the Tarissan acid lake (TAS) at depths less than 800 m. Following the April 2018 earthquake (Mlv 4.1), which likely damaged the dome, swarms intensified and show ...

Exploring the Formation and Age of Irregular Mare Patches (IMPs) to the Southeast of the Chang'e‐5 Landing Site

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Recently, possible exceptionally young mare volcanic glass beads were discovered in Chang'e‐5 (CE‐5) samples. Isotopic dating suggests an age of approximately 120 Ma, presenting new challenges to existing lunar thermal evolution models. Thus, our research focuses on the source region of Rima Mairan, a branch of Rima Sharp, and its surrounding ...
