Multisensor Characterization of the Incandescent Jet Region of Lava Fountain-Fed Tephra Plumes [PDF]
Explosive basaltic eruptions eject a great amount of pyroclastic material into the atmosphere, forming columns rising to several kilometers above the eruptive vent and causing significant disruption to both proximal and distal communities.

Unravelling the links between seismo-acoustic signals and eruptive parameters: Etna lava fountain case study. [PDF]
AbstractDeriving eruption source parameters from geophysical data is critical for volcano hazard mitigation, yet remains a challenging task in most volcanoes worldwide. In this work, we explored the temporal relationship between geophysical signals and eruptive parameters measured during six explosive episodes from the New South-East Crater of Mt. Etna

A Multi-Sensor Approach for Volcanic Ash Cloud Retrieval and Eruption Characterization: The 23 November 2013 Etna Lava Fountain [PDF]
Volcanic activity is observed worldwide with a variety of ground and space-based remote sensing instruments, each with advantages and drawbacks. No single system can give a comprehensive description of eruptive activity, and so, a multi-sensor approach ...

Bubble-enhanced basanite–tephrite mixing in the early stages of the Cumbre Vieja 2021 eruption, La Palma, Canary Islands [PDF]
Syneruptive magma mixing is widespread in volcanic eruptions, affecting explosivity and composition of products, but its evidence in basaltic systems is usually cryptic.

PM10 measurements in urban settlements after lava fountain episodes at Mt. Etna, Italy: pilot test to assess volcanic ash hazard to human health [PDF]
We have carried out a preliminary study on the potential risks caused by the sub-10 µm fraction of volcanic ash (particulate matter, PM10) after the basaltic explosive eruptions from Mt.

The intense explosive activity of lava fountain sequences from Voragine crater at Etna volcano: new insights through high-precision borehole strain recordings [PDF]
Mount Etna is well known for its frequent lava fountains, or paroxysms, characterized by their intense explosive activity. Over the past decades, the Southeast Crater has been the most prolific, generating over a hundred events.

Liquid jet breakup regimes in lava fountains
Primary magma fragmentation in “fluid-dominated” (as opposed to “ash-dominated”) lava fountains involves the hydrodynamic breakup of a jet of magma. Lava fountains partly resemble industrial liquid jets issued from a nozzle into a quiescent atmosphere, on which there is a vast literature. Depending on the internal liquid properties, nozzle diameter and

Real-time estimation of eruptive source parameters during explosive volcanic eruptions is a major challenge in terms of hazard evaluation and risk assessment as these inputs are essential for tephra dispersal models to forecast the impact of ash plumes ...

Near Real-Time Monitoring of the Christmas 2018 Etna Eruption Using SEVIRI and Products Validation [PDF]
On the morning of 24 December 2018, an eruptive event occurred at Etna, which was followed the next day by a strong sequence of shallow earthquakes.
