High vs Low Pressure Magma Chambers at Ventotene Volcano (Tyrrhenian Sea, Central Italy): Implication for Pure Plinian vs Caldera-Forming Eruptions

Gaeta M., Perinelli C., Cardello G.L., Conte A.M., Monaco L., Pavese R., Sottili G., Palladino D.M.

Journal of Petrology, Volume 66, Issue 10

Eruptive styles are influenced by multiple factors, including magma chamber depth. At Ventotene volcano (Pontian Islands, Tyrrhenian Sea, central Italy), a transition at ~300 ka is observed from repeated ‘pure Plinian’ eruptions—i.e....

Very fast canyon formation and evolution along active volcanic flanks: A case from Stromboli Island

Casalbore D., Di Traglia F., Favalli M., Fornaciai A.,, Romagnoli C.,, Civico R., Ricci T., Berardino P., Borselli L., Calabria P., Calvari S., Carlà T. Casagli N., Casu F., Chiocci F.L., De Cesare...

Geomorphology, 488, 109961.

Active insular volcanoes are generally characterized by their rapid morphological evolution, as a close interplay exists between eruptive activity and erosive-depositional processes in such volcanoes. The Sciara del Fuoco depression, a sector collapse...

Tephrochronology of the NDT09 core in the Marsili basin: implications for the timing and dynamics of volcanic eruptions of the southern Tyrrhenian in the last c. 15 ka

Di Roberto A., Re G., Insinga D.D., Scateni B., Caricchi C., Siravo G., Petrelli M., Fisauli G., Cascella A., Bronzo L., Lirer F., Macrì P.

Bulletin of Volcanology 87:124

We report a detailed tephrostratigraphic characterization of the 5.7 m long NDT09 marine sediment sequence retrieved from the Marsili Basin in the southern Tyrrhenian Sea. Glass composition was determined through a combination of electron microprobe analysis...

Lava Tube System Development Defined by Multispectral Imaging and InSAR: The Case of the 2024 Eruption of Fernandina Volcano (Galápagos)

Hrysiewicz A., LaFemina P. C., Bell A., Galetto F., Vallejo S., Bernard B., Holohan E. P.

Journal of Geophysical Research: Solid Earth, 130, e2025JB032265

Lava tubes are subsurface conduits within a lava flow that feed its advance. Lava tube detection is important to understand lava flow dynamics and to mitigate geohazards. Here we use InSAR-derived surface motion data, in combination with shortwave and...

The discovery of extinct volcanoes in the 18th century and the anthology on volcanoes by Giovanni Targioni Tozzetti (1779)

Sammuri P.

Rendiconti Online Soc. Geol. It, Vol. 67 (2025), pp. 79-91

This work aims to represent the panorama of the level reached by volcanological knowledge in the eighteenth century, having as reference the book on volcanoes written by Giovanni Targioni Tozzetti. The study starts from the precursors of the seventeenth...
