Comprehensive global inventory of submarine mud volcanoes [PDF]

open access: yesScientific Data
Systematic morphometric studies of submarine potential geohazard elements such as mud volcanism are still limited in the scientific literature. To fill this gap and contribute to the global geohazard databases, we present a comprehensive inventory of ...

High-Abundance Heterotrophic Bacteria Inhabit the 85° E Hydrothermal Plume of the Explosive Volcanic Zone at Gakkel Ridge, Arctic Ocean [PDF]

open access: yesBiology
While under-ice submarine hydrothermal systems provide critical insights into extremophile adaptations, the ecological impacts of explosive volcanism on these ecosystems remain poorly constrained.

abundance of submarine volcanism in arcs

open access: yesVolcanica
Explosive submarine arc volcanoes can cause tsunamis, affect climate, and pose hazards to airplanes and ships. Although 70 % of the Earth is submarine, only 15 % of Holocene arc volcanoes in the Smithsonian Global Volcanism database are submarine ...

Anomalous Pacific‐Antarctic Ridge Volcanism Precedes Glacial Termination 2 [PDF]

open access: yesGeochemistry, Geophysics, Geosystems, 2018
We present results from a well‐dated sediment core on the Pacific‐Antarctic Ridge (PAR) that document a ∼15 cm thick layer of basaltic ash shards that precedes the penultimate deglaciation (Termination 2).

Early arc crust formation preserved in the Grenadines archipelago, southern Lesser Antilles arc [PDF]

open access: yesRoyal Society Open Science
Intra-arc diversity in volcanic activity and composition is ubiquitous, but its underlying causes remain largely unresolved in many settings. In this work, we examine such variability in the Grenadines archipelago, southern Lesser Antilles arc.

The Cabo de Gata-Níjar UNESCO Global Geopark (Almería, Spain). A Volcanism between Land and Sea [PDF]

open access: yesGeoconservation Research, 2023
Cabo de Gata-Níjar geopark is an exceptional volcanic zone in the western Mediterranean because of the submarine effusive volcanism and the large volume of subaerial pyroclastic deposits; volcanism developed between land and sea.

Age of Initial Submarine Volcanism in the Paleo-Tsushima Basin and Implications for Submarine Volcanism in the Opening Stage of the Japan Sea in Northern Kyushu

open access: yesGeosciences, 2021
The Tsushima Lapilli Tuff, the thickest tuff in the Taishu Group on Tsushima Island, underwent a thermal event after deposition, and has not previously yielded a reliable age because various ages have been reported.

Dynamics of deep-submarine volcanic eruptions

open access: yesScientific 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 ...

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

open access: yesFrontiers 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

Characteristics of Sub-Aerially Emplaced Pyroclasts in the Surtsey Eruption Deposits: Implications for Diverse Surtseyan Eruptive Styles

open access: yesGeosciences, 2022
The 1963–1967 shallow-to-emergent eruption in Iceland’s Vestmannaeyjar earned a place in the history of volcanology by creating the island of Surtsey while under close observation of volcanologist Sigurdur Thorarinsson (Sigurður Þórarinsson in Icelandic).
