The helium and carbon isotopic signature of Ocean island basalts: Insights from Fogo volcano (Cape Verde archipelago)

Lo Forte F.M, Boudoire G., Frezzotti M.L., Rotolo S.G., Sandoval-Velasquez A., Viveiros F., Zanon V., Aiuppa A., Rizzo A.L.

Earth and Planetary Science Letters, 645, (2024) 118930

Fluid inclusions (FI) entrapped in phenocrysts carried by Ocean Island Basalts (OIB) contain key information on volatiles’ abundance and origin in their mantle sources. Here, we add new piece of knowledge to our understanding of volatile geochemistry...

Testing paleomagnetic dating on pre-historic flank eruptions from SE slope of Etna volcano

Magli A., Speranza F., Branca S., Corsaro R. A., Coltelli M., Malaguti A. B., Giordano G.

Journal of Geophysical Research: Solid Earth, 129, e2023JB028314

During the last 20 kyr, the Etna volcano has been characterized by almost continuous summit eruptions and by less frequent—yet definitely more destructive—flank eruptions issuing at <1,000 m asl altitudes and reaching the Ionian Sea. The...

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.

Geophysical Research Letters, 51

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.

Journal of Volcanology and Geothermal Research 454C (2024) 108164

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...

Surveying volcanic crises exercises: From open-question questionnaires to a prototype checklist

Massaro S., Sandri L., Geyer A., Cristiani C., Nave R., Barsotti S., Loughlin S., Puglisi G.

Journal of Volcanology and Geothermal Research, Volume 440, August 2023, 107850

Volcanic crisis exercises are usually run to test response capabilities, communication protocols, and decision-making procedures by agencies with responsibilities to cope with scenarios of volcanic unrest with inherent uncertainty, such as volcano observatories...
