Lava Lake Spattering Drives Seismic Tremor During the Geldingadalir 2021 Eruption, Iceland

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract Volcanic eruptions generate a continuous ground motion that is commonly referred to as tremor. Although tremor is used worldwide for real‐time monitoring of volcanoes, the mechanisms involved are generally poorly understood. Here, we study the episodic effusion during 2021 Geldingadalir eruption. We use photogrammetric data and videos acquired

On the Complex Topography of Marine Volcanoes and Its Control on the Spatial and Magnitude Distribution of Surface Displacement

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Marine volcanoes exhibit significant topographic relief, as they extend from deep below sea level to thousands of meters above. These volcanoes often have complex, asymmetric topographies due to the submersion of their flanks, yet deformation models often approximate this topographic surface as flat and overlook its effect in modeling ...

Monitoring radon emission anomalies at Stromboli Island as a tracer of eruptive events and “near field” earthquakes

EPJ Web of Conferences, 2012
Radon emission from soil at Stromboli Island has been monitored since 2002 utilizing a network of 25 stations and exposing two kinds of detectors: E-PERM and calibrated track-etches (LR115).

First observational evidence for the CO₂-driven origin of Stromboli's major explosions [PDF]

Solid Earth, 2011
We report on the first detection of CO2 flux precursors of the till now unforecastable "major" explosions that intermittently occur at Stromboli volcano (Italy).

Automatic Signal Discrimination Using Machine Learning on the Data From the Central and Eastern European Infrasound Network

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract A labeled data set of 216,681 infrasound detections was compiled using data from the Central and Eastern European Infrasound Network (CEEIN). Detections associated with quarry blasts, thunderstorms, eruptions of the Etna volcano, industrial activity, and the war in Ukraine were categorized using ground truth information, such as seismic and ...

Lava Flow Monitoring Using TET-1 Satellite [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Lava flow monitoring using satellites provides information on the temporal evolution of volcanic activity. It is usually done using metrological satellites because of the lack of more suitable satellites.

The Effect of Edifice Slope, Failure Surface Geometry, and Magma Intrusion Depth on the Development of Flank Instability at Volcanoes

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Magmatism is a known driver of flank instability at volcanoes where flank slip has been observed. Studies of instability at Kı̄lauea, Piton de la Fournaise, and Etna imply that long‐term flank motion likely requires the presence of a layer accommodating the sliding, and a force, such as magma intrusion, that promotes slip.

2005–2024 Time–Space Features of VT Seismicity at Stromboli: New Insights into the Volcano Plumbing System and Link to Effusive Eruptions

Applied Sciences
Volcano-tectonic seismic events (VT) are quite rare at Stromboli, numbering about ten events per year and generally with low magnitude. Using a dataset of 98 events from the 2005–2024 period, we report an improved relocation of VT events here.

Numerical Modeling Integrated With Field Observations and Analytical Data of the 2021 Cumbre Vieja Eruption Improves Understanding of Eruption Dynamics at Mafic Volcanoes

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Abrupt transitions in eruptive style are common at mafic volcanoes, possibly leading to styles that potentially damage infrastructures and threaten the surrounding communities. During the 19th September–13th December 2021 Cumbre Vieja eruption (La Palma, Canary Islands), rapid changes in eruptive style were observed, from vigorous lava ...

Self-sustained oscillator as a model for explosion quakes at Stromboli Volcano [PDF]

Nonlinear Processes in Geophysics, 2002
We analyze seismic signals produced by explosion-quakes at Stromboli Volcano. We use standard nonlinear procedures to search a low-order effective dynam-ics. The dimension of the reconstructed phase space depends on the number of samples.
