Reconstructing the eruptive history of Antarctic volcanoes is often challenging due to limited outcrops exposure, extensive ice cover, and extreme environmental conditions. Here, we present detailed volcanological, textural, and geochemical analyses of three tephra layers (DPT 1, DPT 2, and DPT 3) from an englacial ice sequence at 2581 m asl on the southwest flank of Mount Melbourne, northern Victoria Land (Antarctica). Using...

Understanding the processes leading up to caldera-forming eruptions is essential for identifying precursory signals of catastrophic events. While these phenomena have been extensively studied in silicic systems, mafic volcanoes present unique challenges. Indeed, the high eruptive temperatures of mafic magmas might imply short storage in the cold upper crust and, thus, short periods of unrest preceding eruption, which could cha...

The South-East Crater (SEC) at Mt. Etna started a period of lava fountaining in December 2020, producing over 60 paroxysms until February 2022. The activity had an intense sequence from February 16 to April 1, 2021, totaling 17 paroxysmal events separated by repose times varying from 1 to 7 days. The eruptive sequence was extensively monitored, providing a unique opportunity to relate the chemistry and texture of the erupted p...
