A Preliminary Hazard Assessment of Kolumbo Volcano (Santorini, Greece)

GeoHazards
Volcanic eruptions stand as destructive threats to adjacent communities, unleashing multiple hazards such as earthquakes, tsunamis, pyroclastic flows, and toxic gases.

The role of submarine volcanism in atmospheric chemistry

Earth and Planetary Science Letters
Submarine volcanic eruptions can form subaerial plumes that reach the stratosphere. Despite this, the impact of submarine eruptions on climate remains unclear due to a lack of clear geological record, with the recent large-scale Hunga eruption on 15 January 2022 being considered as an isolated case. Here, we review the impact of submarine and subaerial

Submarine volcanic microbiota record three volcano-induced tsunamis

Communications Earth & Environment
The precise determination of sediment provenance not only yields insights into past tsunami events but also offers a window into understanding the genesis of tsunamis in distinct environments, such as volcanic regions. Through meticulous analysis of core

Volcanism and seismicity in the Indo-Australian seismic belt: manifestations of intraplate tectonics

Annals of Geophysics, 1978
Disregarding the mid-oceanic ridges, the oceanic part of the Indo-<br />Australian Seismic Belt is the longest, seismically active zone in the<br />world-ocean. It begins west of Ceylon and runs towards Australia.

A Failed Rift in the Eastern Adventure Plateau (Sicilian Channel, Central Mediterranean)

Journal of Marine Science and Engineering
Widespread volcanism has been known in the Sicilian Channel for a long time, even if some submarine volcanoes have only recently been discovered. Most of this volcanism formed along the NNE-trending transfer zone known as the Capo Granitola–Sciacca Fault

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Multi-stage volcanic island flank collapses with coeval explosive caldera-forming eruptions

Scientific Reports, 2018
Volcanic flank collapses and explosive eruptions are among the largest and most destructive processes on Earth. Events at Mount St. Helens in May 1980 demonstrated how a relatively small (300 km3), but can also occur in complex multiple stages.

Resolving Taxonomic Boundaries in the New Zealand Senecio matatini Complex (Senecioneae, Asteraceae): Evidence from Genotyping by Sequencing of Limestone‐Associated Forms

New Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
The Senecio matatini complex in New Zealand has a convoluted taxonomic and nomenclatural history that has not been fully resolved. This is largely due to the incomplete sampling of morphologically diverse but highly threatened limestone populations in the eastern South Island in previous genetic studies.

An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks.
