Ionospheric Disturbances During the 4 December 2015, Mt. Etna Eruption

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract This study presents the detection and characterization of co‐volcanic ionospheric disturbances (CVIDs) associated with Mt. Etna's large‐scale lava fountain (Italy). Leveraging a dense and proximal GNSS network, we identify local Total Electron Content (TEC) perturbations extending up to ∼ ${\sim} $200 km south/southwest of the vent.

Seismological monitoring of the February 2007 effusive eruption of the Stromboli volcano

Annals of Geophysics, 2007
On February 27, 2007, the Stromboli volcano, which has usually been characterized by moderate explosive activity, started an effusive eruption with a small lava flow down the NW flank.

Seismic Tomography of a Newborn Volcano

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract On 19 September 2021, in La Palma, Canary Islands (Spain), a new volcano, later named Tajogaite, erupted. We determined the shallow seismic tomography model of Tajogaite Volcano, including the 3D distributions of Vp, Vs, and Vp/Vs. The tomography of the volcanic edifice has been performed using a combination of a three‐component amplitude ...

Exploring the utility of GPR to document the explosive history of old (> 100 ka) scoria cones

Journal of Applied Volcanology
Scoria cones are the most common volcanic landform on Earth. While eruptive styles range from effusive to explosive, the low-energy spectrum of activity is best documented.

An Integrated Geophysical Approach to Track Magma Intrusion: The 2018 Christmas Eve Eruption at Mount Etna

Geophysical Research Letters, 2019
On 24 December 2018, a violent eruption started at Mount Etna from a fissure on the southeastern flank. The intrusive phenomenon, accompanied by intense Strombolian and lava fountain activity, an ash‐rich plume, and lava flows, was marked by significant ...

Controls on Water‐Magma Interactions at Hydraulically‐Charged Volcanic Islands

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The interaction of rising magma with groundwater can produce phreatomagmatic explosions, which, given their enhanced explosivity and unpredictability, increase the hazard potential of volcanic eruptions. To investigate the link between groundwater occurrence and phreatomagmatism, we compare the volcanic record of Flores Island (Azores) with ...

Temporal and morphological eruption characteristics of lava flows from the Holocene La Taza monogenetic cone obtained from petrology and LiDAR imagery (Michoacán, Mexico)

Volcanica
The Holocene La Taza andesitic volcano is one of over 1000 volcanic centers located within the Michoacán-Guanajuato Volcanic Field (MGVF) in central-western Mexico. La Taza (~8500–8200 yr BP) represents one possible eruption style within the field, with

Dynamics of Strombolian explosions: Inferences from field and laboratory studies of erupted bombs from Stromboli volcano [PDF]

Journal of Geophysical Research: Solid Earth, 2014
AbstractStrombolian activity is characterized by repeated, low energy, explosions and is named after the volcano where such activity has persisted for around 2000 years, i.e., Stromboli (Aeolian Islands, Italy). Stromboli represents an excellent laboratory where measurements of such explosions can be made from safe, but close, distances. During a field

The “Analogs for VENus' GEologically Recent Surfaces” (AVENGERS) Initiative: Using Terrestrial Analogs to Study Recent Volcano‐Tectonic Activity on Venus and Inform the Characterization of Terrestrial Exoplanets

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Several missions to Venus have recently been selected for launch, opening a new era for the exploration of the planet. A key question these missions seek to address is whether Venus is geologically active today. Detecting active volcanism on Venus would contribute to a better understanding of volcanic and atmospheric processes on Earth.
