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.

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

The evolution of the 2022–2024 eruption at Home Reef, Tonga, analyzed from space shows vent migration due to erosion [PDF]
Scientific ReportsOn September 9, 2022, a new eruption period began at the submarine volcano Home Reef, part of the Tonga Volcanic Arc. We integrated multi-sensor/multi-platform satellite datasets, including very high spatial resolution TerraSAR-X radar and PlanetScope ...

The 2011 submarine volcanic eruption in El Hierro (Canary Islands) [PDF]
Geology Today, 2013 Forty years after the Teneguía Volcano (La Palma, 1971), a submarine eruption took place off the town of La Restinga, south of El Hierro, the smallest and youngest island of the Canarian Archipelago. Precursors allowed an early detection of the event and

Submarine and Subaerial Morphological Changes Associated with the 2014 Eruption at Stromboli Island
Remote Sensing, 2021 Stromboli is an active insular volcano located in the Southern Tyrrhenian Sea and its recent volcanic activity is mostly confined within the Sciara del Fuoco (SdF, hereafter), a 2-km wide subaerial–submarine collapse scar, which morphologically dominates

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).

Dynamics of deep-submarine volcanic eruptions
Scientific Reports, 2022 AbstractDeposits 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 vent, the erupting particle-laden mixture entrains and mixes with sufficient seawater that ...

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
