The 2020–2022 paroxysmal episodes of the South-East Crater (Mt. Etna): insights into high-frequency eruptive activity from petrological monitoring
Corsaro R.A., Miraglia L., Arienzo I., ·Di Renzo V.
Over the last 20 years, the South-East Crater (SEC) of Etna has produced high-intensity explosive activity including Strombolian explosions and lava fountains associated with lava effusion. In the 2020–2022 period, SEC volcanic activity was characterized...
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,...
Crustal Structure of Etna Volcano (Italy) From P-Wave Anisotropic Tomography
Lo Bue R., Rappisi F., Firetto Carlino M., Giampiccolo E., Cocina O., Vanderbeek B. P., Faccenda M.
Several seismic tomographic studies have been carried out to outline the intricate interplay between tectonics and magma uprising at Etna volcano. Most of these studies assume a seismically isotropic crust. Here we employ a novel methodology that accounts...
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...
