The role of crustal contamination throughout the 1329-2005 CE eruptive record of Mt.Etna volcano, Italy

Takach M.K., Bohrson W.A., Spera F.J., Viccaro M.

Journal of Petrology, 65, egae028

The nearly continuous volcanic eruption record at Mt. Etna dating back ~700 years provides an excellent opportunity to investigate the geochemical evolution of a highly active volcano. Of particular interest is elucidating the cause of selective enrichment...


Changing magma recharge/discharge dynamics during the 2020–22 lava fountaining activity at Mt. Etna revealed by tilt deformation and volcanic tremor

Cardone M., Cannata A., Giuffrida M., Iozzia A., Minio V., Viccaro M., Gambino S.

Journal of Volcanology and Geothermal Research, 449.

Mt. Etna exhibited 62 lava fountaining events between December 13, 2020 and February 21, 2022. We analyzed tilt deformations and volcanic tremor amplitude time series, to characterize both eruptions and the preceding preparatory phases in terms of magnitude...


The last 1100 years of activity of La Fossa caldera, Vulcano Island (Italy): new insights into stratigraphy, chronology, and landscape evolution

Di Traglia F., Pistolesi M., Bonadonna C., Rosi M.

Bulletin of Volcanology 86, 47 (2024).

A detailed study of past eruptive activity is crucial to understanding volcanic systems and associated hazards. We present a meticulous stratigraphic analysis, a comprehensive chronological reconstruction, thorough tephra mapping, and a detailed analysis...


Medieval and recent SO2 budgets in the Reykjanes Peninsula: implication for future hazard

Caracciolo A., Bali E., Ranta E., Halldórsson S.A., Guðfinnsson G.H., Óskarsson B.V.

Geochemical Perspectives Letters (2024). 30, 20-27.

Exposure to volcanic SO2 can have adverse effects on human health, with severe respiratory disorders documented on short- and long-term timescales. Here, we use melt inclusion and groundmass glass data to calculate potential syneruptive SO2 emissions...


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...
