Lahars on Atlasov Island in September-October 2022 (Kuril Islands)

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
The article provides information about nival-volcanogenic, possibly glacial-volcanogenic, mudflows (lahars) on three streams on the south side of Atlasov Island (Kuril Islands, Russia). The island is an active stratovolcano Alaid, 2339 m asl high.

Landslides triggered by the December 2021 Eastern Bays storm, Banks Peninsula, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1000-1014, December 2025.
ABSTRACT On 16 December 2021, the Eastern Bays region of Banks Peninsula, Canterbury, was affected by a high intensity rainfall event which triggered >1300 landslides. Landslides triggered by the event caused widespread damage to agricultural land and infrastructure, which cut off road access to several communities.

Mechanisms of Ash Generation at Basaltic Volcanoes: The Case of Mount Etna, Italy

Frontiers in Earth Science, 2019
Basaltic volcanism is the most widespread volcanic activity on Earth and planetary bodies. On Earth, eruptions can impact global and regional climate, and threaten populations living in their shadow, through a combination of ash, gas and lava.

Rainfall‐triggered landslides from the January 2023 1‐in‐200 year storm at Maungakiekie/One Tree Hill, Auckland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1049-1063, December 2025.
ABSTRACT We describe engineering geological characteristics and failure mechanisms of shallow soil landslides activated on Maungakiekie/One Tree Hill in central Auckland, New Zealand on 27 January 2023. The hill is a scoria cone in the young Auckland Volcanic Field (AVF), and formed ∼60 ka BP.

Self‐Potential Signal Associated With Hydrothermal System Disrupted by Extreme Raining Events; The Case Study of Formica Leo, Piton de la Fournaise, La Réunion Island

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract The scoria cones called Formica Leo located at the base of the Piton de la Fournaise terminal cone have been chosen for its significant positive Self‐Potential (SP) anomalies associated with hydrothermal uprising fluids to monitor SP signal and study its dynamics in relation with huge and extreme rainfall events.

Explosive Paroxysmal Events at Etna Volcano of Different Magnitude and Intensity Explored through a Multidisciplinary Monitoring System

Remote Sensing, 2022
Between 13 December 2020 and 21 February 2022, Etna volcano produced a sequence of 66 paroxysmal explosive eruptions, with Strombolian activity at the summit craters climaxing in lava fountains and eruption columns extending several kilometers above the ...

Numerically Efficient Model for the Nucleation, Growth, and Coalescence of Bubbles in Magma

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract We present a numerical model to describe the nucleation, growth, and coalescence of bubbles in a decompressed magma. The new model enables us to calculate the bubble size distribution (BSD) at a low computational cost by taking the bubble mass as a variable.

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.

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.
