Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

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.

The Significance of Magnetic Fabrics Preserved in Hydrothermally Altered Rocks

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Anisotropy of Magnetic Susceptibility (AMS) and Anisotropy of Magnetic Remanence (AMR) are critical petrofabric tools for investigating the evolution of volcano‐magmatic, tectonic, and surface process systems. These highly sensitive techniques can distinguish multiple magnetic fabrics within individual samples, crucial in assessing archives of

Modeling the Impact of Initiation Parameters on the Dynamics of the 2012 Te Maari Laterally Confined Debris Avalanche

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Volcanic debris avalanches can transform into highly mobile debris flows, reaching long runout distances and posing significant hazards to downstream populations. This high mobility arises from complex, evolving rheological behavior driven by dynamic changes in pore pressure, internal resistance, and material properties during the flow.
