Pumice Raft Detection Using Machine-Learning on Multispectral Satellite Imagery

open access: yesFrontiers in Earth Science, 2022
Most of Earth’s volcanic eruptions occur underwater, and these submarine eruptions can significantly impact large-scale Earth systems (e.g., enhancing local primary production by phytoplankton).

How to turn off a lava lake? A petrological investigation of the 2018 intra-caldera and submarine eruptions of Ambrym volcano

open access: yesBulletin of Volcanology, 2021
In December 2018, an unusually large intra- and extra-caldera eruption took place at Ambrym volcano (Vanuatu). The eruption drained the volcano’s five active lava lakes and terminated, at least momentarily, the surface activity that had been ongoing for ...

Seawater-magma interactions sustained the high column during the 2021 phreatomagmatic eruption of Fukutoku-Oka-no-Ba

open access: yesCommunications Earth & Environment, 2022
High eruption plumes during submarine eruptions are promoted by seawater vaporisation and decoupled from erupted mass, according to combination of satellite remote sensing observations and plume modelling.

Low-degree mantle melting controls the deep seismicity and explosive volcanism of the Gakkel Ridge

open access: yesNature Communications, 2022
Joint implementation of seismic tomography and numerical thermo-mechanical modeling sheds light to the causes of explosive submarine volcanic eruptions on the Gakkel Ridge and deeply penetrating seismicity down to 25 km depth.

From basalt to biosphere: Early non-vent community succession on the erupting Vailulu’u deep seamount

open access: yesFrontiers in Marine Science, 2023
Volcanic eruptions provide rare opportunities to witness the biological recolonization of areas covered by new lava flows by effectively resetting the ecological succession clock to zero. The role of submarine volcanic eruptions as disturbance events and

Seismo-acoustic evidence for vent drying during shallow submarine eruptions at Bogoslof volcano, Alaska

open access: yesBulletin of Volcanology, 2019
Characterizing the state of the volcanic vent is key for interpreting observational datasets and accurately assessing volcanic hazards. This is particularly true for remote, complex eruptions such as the 2016–2017 Bogoslof volcano, Alaska eruption ...

Volcanic Eruptions in the Deep Sea [PDF]

open access: yesOceanography, 2012
Volcanic eruptions are important events in Earth's cycle of magma generation and crustal construction. Over durations of hours to years, eruptions produce new deposits of lava and/or fragmentary ejecta, transfer heat and magmatic volatiles from Earth's ...

The Volcanic Relief within the Kos-Nisyros-Tilos Tectonic Graben at the Eastern Edge of the Aegean Volcanic Arc, Greece and Geohazard Implications

open access: yesGeosciences, 2021
The active Kos-Nisyros-Tilos volcanic field is located in the eastern sector of the Aegean Volcanic Arc resulting from the subduction of the African plate beneath the Aegean plate. The volcanic activity is developed since Middle Pleistocene and it occurs
