The December 2018 eruption at Etna volcano: a geochemical study on melt and fluid inclusions
Correale A., Corsaro R.A., Miraglia L., Paonita A., Rotolo S.G.
This study focus on the Mt Etna December 2018 eruption with the aim of investigating the geochemical characteristics of the feeding magma. New data on major and trace element geochemistry of olivine-hosted melt inclusions (MI) in volcanic products are...
Upper Miocene volcanic ash layers from central Italy: tracking down the volcanic source
Roverato M., Farina F., Lupi M., Ovtcharova M., Montanari A., Bonini M., Montanari D.
The Mediterranean region has been characterized by intense explosive volcanism since the Eocene. These eruptions ejected tephra, including fine-grained ash, which were thrown into the air and dispersed over wide areas to later be deposited as ash layers,...
Sierra Negra, Galápagos: A resurgent-block basaltic caldera
Acocella V., Galetto F., Amelung F., Aguaiza S.
Caldera resurgence is rare at mafic volcanoes. Here we consider the well-exposed resurgence at Sierra Negra caldera (Galápagos) to investigate how resurgence develops at a mafic system. Based on topographic and field analysis, the structure of...
Constraining proximal grainsize distribution of tephra from paroxysmal eruptions at Etna volcano
Amadio F., Pioli L., Scollo S.
This study examines proximal deposits associated with 17 lava fountains occurring at the South-East Crater between 16/02 and 1/04, 2021. This eruptive crisis gave rise to some of the most intense eruptions at Etna in the last decade. We studied products...
From land to sea: a new high-resolution bathymetry and topography of the Campi Flegrei area, Southern Italy
Gianardi R., Bisson M., Cocchi L., Isaia., Passaro S., Sepe V., Spinetti C.
Campi Flegrei is an active volcanic area located in the Campanian region (southern Italy). It is characterized by a caldera structure including a subaerial portion densely populated and a submarine area represented by the Gulf of Pozzuoli. Altimetry data...
