The 2nd to 4th century explosive activity of Vesuvius: new data on the timing of the upward migration of the post-A.D. 79 magma chamber

Annals of Geophysics, 2013
We present volcanological data on the deposits of the Santa Maria Member (SMM), the eruption cycle occurred at Vesuvius (Italy) in the period between the A.D. 79 plinian and the A.D. 472 subplinan eruptions.

The bursting behavior of gas slugs: laboratory and analytical insights into Strombolian volcanic eruptions.

, 2012
The aim of this thesis is to study how explosive behavior and geophysical signals in a volcanic conduit are related to the development of overpressure in slug-driven eruptions. A first suite of laboratory experiments of gas slugs ascending in analogue conduits was performed.

Systematic Slowing of Initially Rapid Retreat of New Coasts Formed by Historical Eruptions in Volcanic Islands

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 8, August 2025.
Abstract Due to their exposure to waves, volcanic island coasts typically retreat with cliff collapses and other erosional processes. Understanding how retreat rates vary over time and in response to environmental and other factors could be useful for geohazard assessment, coastal management and landform reconstruction.

The Contribution of Multi-Sensor Infrared Satellite Observations to Monitor Mt. Etna (Italy) Activity during May to August 2016

Remote Sensing, 2018
In May 2016, three powerful paroxysmal events, mild Strombolian activity, and lava emissions took place at the summit crater area of Mt. Etna (Sicily, Italy).

Relation Between Volcanic Tremor and Geodetic Strain Signals During Basaltic Explosive Eruptions at Etna

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Volcano deformation and seismicity during basaltic explosive eruptions are the expressions of the processes that regulate magma ascent from depth to surface. Both deflation rate and seismic tremor are hypothesized to scale with magma ascent rate, which plays a significant role in the resulting eruptive style.

The ash-fall hazard from a Plinian eruption at Colima Volcano, Mexico

Annals of Geophysics, 2010
The historical eruptive activity at Colima Volcano has been characterized by Strombolian and Merapi type eruptions and Vulcanian explosions associated with dome growth, which have ended in a Plinian eruption about every 100 years.

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 ...

Fragmentation Processes During Strombolian Explosions Revealed Using Particle Size Distribution Mapping

Frontiers in Earth Science, 2020
Fragmentation dynamics can be described by the size distribution of the fragments generated during an explosion. We approach the problem of magma fragmentation during a Strombolian explosion using the grain size distribution (GSD) of a ballistically ...

Pyroclast Tracking Velocimetry: A particle tracking velocimetry‐based tool for the study of Strombolian explosive eruptions [PDF]

Journal of Geophysical Research: Solid Earth, 2014
AbstractImage‐based techniques enable high‐resolution observation of the pyroclasts ejected during Strombolian explosions and drawing inferences on the dynamics of volcanic activity. However, data extraction from high‐resolution videos is time consuming and operator dependent, while automatic analysis is often challenging due to the highly variable ...

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 ...
