Atmosphere injection of sea salts during large explosive submarine volcanic eruptions [PDF]

Scientific Reports, 2023
The 15 January 2022 submarine eruption at Hunga volcano was the most explosive volcanic eruption in 140 years. It involved exceptional magma and seawater interaction throughout the entire submarine caldera collapse.

Dynamics of deep-submarine volcanic eruptions

Scientific Reports, 2022
Deposits from explosive submarine eruptions have been found in the deep sea, 1–4 km below the surface, with both flow and fall deposits extending several km’s over the seafloor. A model of a turbulent fountain suggests that after rising 10–20 m above the

Cascading events during the 1650 tsunamigenic eruption of Kolumbo volcano [PDF]

Nature Communications, 2023
Volcanic eruptions can trigger tsunamis, which may cause significant damage to coastal communities and infrastructure. Tsunami generation during volcanic eruptions is complex and often due to a combination of processes.

Eruption of South Sarigan Seamount, Northern Mariana Islands: Insights into Hazards from Submarine Volcanic Eruptions [PDF]

Oceanography, 2014
The eruption of South Sarigan Seamount in the southern Mariana arc in May 2010 is a reminder of how little we know about the hazards associated with submarine explosive eruptions or how to predict these types of eruptions. Monitored by local seismometers

Asymmetric magma plumbing system beneath Axial Seamount based on full waveform inversion of seismic data [PDF]

Nature Communications
The architecture of magma plumbing systems plays a fundamental role in volcano eruption and evolution. However, the precise configuration of crustal magma reservoirs and conduits responsible for supplying eruptions are difficult to explore across most ...

Anomalous trends in global ocean carbon concentrations following the 2022 eruptions of Hunga Tonga-Hunga Ha’apai [PDF]

Communications Earth & Environment
We report on observed trend anomalies in climate-relevant global ocean biogeochemical properties, as derived from satellite ocean color measurements, that show a substantial decline in phytoplankton carbon concentrations following eruptions of the ...

Pumice Raft Detection Using Machine-Learning on Multispectral Satellite Imagery

Frontiers 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).

Out of the blue: Volcanic SO2 emissions during the 2021–2022 eruptions of Hunga Tonga—Hunga Ha’apai (Tonga)

Frontiers in Earth Science, 2022
Most volcanism on Earth is submarine, but volcanic gas emissions by submarine eruptions are rarely observed and hence largely unquantified. On 15 January 2022 a submarine eruption of Hunga Tonga-Hunga Ha’apai (HTHH) volcano (Tonga) generated an explosion

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

Communications 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.
