Clusters of lava fountain events identified on strainmeter data at Etna volcano

, 2023
Lava fountains at Etna volcano are spectacular eruptive events characterized by powerful gas jets that expel lava fragments to several hundred meters and volcanic ash to several kilometers above the crater. Ash fall-out and dispersal cause critical hazards to both the vehicular traffic and the aviation, inducing the temporary closure of the southern ...

Episode 4 (2019–2020) Nishinoshima activity: abrupt transitions in the eruptive style observed by image datasets from multiple satellites

Earth, Planets and Space, 2022
In December 2019, a new activity started at Nishinoshima volcano in the southern part of the Izu–Ogasawara arc, Japan. This is now referred to as Episode 4 of a series of activities that began in 2013. We analyzed the eruption sequence, including erupted

A model for gravity changes induced by lava fountaining at Mt Etna

, 2021
<div> <p><span>Lava fountains represent a common eruptive phenomenon at basaltic volcanoes, which consist of jets of fluid lava ejected into the atmosphere from active vents or fissures. They are driven by rapid formation and expansion of gas bubbles during magma ascent.

Rheological control on the dynamics of explosive activity in the 2000 summit eruption of Mt. Etna [PDF]

Solid Earth, 2010
In the period from January to June 2000 Mt. Etna exhibited an exceptional explosive activity characterized by a succession of 64 Strombolian and fire-fountaining episodes from the summit South-East Crater.

Rapid response petrology for the opening eruptive phase of the 2021 Cumbre Vieja eruption, La Palma, Canary Islands

Volcanica, 2022
How and why magmatic systems reactivate and evolve is a critical question for monitoring and hazard mitigation efforts during initial response and ongoing volcanic crisis management.

Cry me a Pele’s tear: new insights on the internal structures of Pele’s tears

Frontiers in Earth Science, 2023
In this paper we present novel observations of internal structures of Pele’s tears and spheres revealed from SEM studies of particles formed within Kilauean lava fountains.

Combining High- and Low-Rate Geodetic Data Analysis for Unveiling Rapid Magma Transfer Feeding a Sequence of Violent Summit Paroxysms at Etna in Late 2015

Applied Sciences, 2021
We propose a multi-temporal-scale analysis of ground deformation data using both high-rate tilt and GNSS measurements and the DInSAR and daily GNSS solutions in order to investigate a sequence of four paroxysmal episodes of the Voragine crater occurring ...

Volcanic plume height monitoring using calibrated web cameras at the Icelandic Meteorological Office: system overview and first application during the 2021 Fagradalsfjall eruption

Journal of Applied Volcanology, 2023
The Icelandic Meteorological Office maintains a national network of webcams designed and built in house for environmental monitoring. During the 2021 Fagradalsfjall eruption these cameras, along with a temporary near-field network of commercial cameras ...
