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 ...

Seismoacoustic Analysis of Possible Vent‐Drying Sequence During Phreatomagmatic Activity on 13 July 2021 at Semisopochnoi Island, Alaska

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Pulse‐like infrasound accompanying volcanic phenomena sometimes suggests interaction with water at the crater. We focus on pulse‐like infrasound observed at Semisopochnoi Island in the Aleutian Arc, Alaska, during the phreatomagmatic activity on 13 July 2021.

Late‐Stage Rift Evolution at Back Arc Basins: Insights From a Tomography Experiment at Orca Volcano, Bransfield Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Back‐arc basins provide insights into the processes governing the evolution of continental rifting to seafloor spreading. The Bransfield basin hosts a back arc rift that is hypothesized to be in the late stages of this transition. Orca volcano is a submarine volcano that lies on the most evolved portion of the rift.

Geophysical fingerprint of the 4–11 July 2024 eruptive activity at Stromboli volcano, Italy [PDF]

Natural Hazards and Earth System Sciences
Paroxysmal eruptions, characterized by sudden and vigorous explosive activity, are frequent at open-vent volcanoes. Stromboli volcano, Italy, is well known for its nearly continuous degassing activity and mild explosions from the summit craters ...

Dynamic strain anomalies detection at Stromboli before 2019 vulcanian explosions using machine learning

Frontiers in Earth Science, 2022
Identifying and characterizing the dynamics of explosive activity is impelling to build tools for hazard assessment at open-conduit volcanoes: machine learning techniques are now a feasible choice.

Lava effusion — A slow fuse for paroxysms at Stromboli volcano? [PDF]

Earth and Planetary Science Letters, 2011
Questo lavoro ha analizzato i risultati del monitoraggio termico delle eruzioni di Stromboli del 2002-2003 e 2007, ed ha mostrato come prima di ogni parossisma il volume di lava eruttato nel corso dell’attivita effusiva sia stato confrontabile.

Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

Advanced Science, Volume 13, Issue 5, 27 January 2026.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

Fluid‐Induced Fault Reactivations in Strike‐Slip Regimes: Temporal Constraints From GNSS and Seismological Analysis in the Peloritani Mts and Aeolian Archipelago (Central Mediterranean)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract Fluids can modify the mechanical properties of rocks, including shear strength and strain behavior. We investigate the timing and magnitude of seismic events during fault motion in strike–slip systems across the Peloritani Mountains (northeastern Sicily) and Aeolian Archipelago using GNSS and seismological data analysis.

Classifying Major Explosions and Paroxysms at Stromboli Volcano (Italy) from Space

Remote Sensing, 2021
Stromboli volcano has a persistent activity that is almost exclusively explosive. Predominated by low intensity events, this activity is occasionally interspersed with more powerful episodes, known as major explosions and paroxysms, which represent the ...

Stratigraphy and lithosedimentological properties of subplinian eruptions from Mt. Taranaki, New Zealand, encompassed by the Ngaere and Pungarehu edifice collapses

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 722-746, December 2025.
ABSTRACT The sudden removal of large portions of a volcanic edifice through collapse can cause depressurisation in the subvolcanic magmatic system, influencing the nature of subsequent eruptions. At Mt. Taranaki, edifice failure has occurred frequently and at different timescales throughout the volcanic history, forming a broad pattern of cyclic ...
