Simulated distributions of pumice rafts in Japan following eruptions at volcanic islands and submarine volcanoes

Progress in Earth and Planetary Science, 2023
Voluminous pumice rafts produced by the 2021 phreatomagmatic eruption of Fukutoku-Oka-no-Ba, a submarine volcano located in the Izu-Bonin Islands, reached many Japanese ports and islands, damaging fisheries and hindering marine traffic and trade.

Reconstruction of submarine eruption processes from FTIR volatile analysis of marine tephra: Example of Oomurodashi volcano, Japan

Frontiers in Earth Science, 2022
Tephra layers in marine sediments are widely used to correlate and date paleoclimate and paleoceanography records, and to determine spatiotemporal changes in magmatic evolution and eruption frequency.

Unraveling Past Submarine Eruptions by Dating Lapilli Tuff-Encrusting Coralligenous (Actea Volcano, NW Sicilian Channel)

Frontiers in Earth Science, 2021
The dating of young submarine volcanic eruptions, with their potential generation of tsunamigenic waves, is essential for a reliable hazard assessment. This is particularly relevant in highly populated coastal areas.

Lightning Rings and Gravity Waves: Insights Into the Giant Eruption Plume From Tonga's Hunga Volcano on 15 January 2022

Geophysical Research Letters, 2023
On 15 January 2022, Hunga Volcano in Tonga produced the most violent eruption in the modern satellite era, sending a water‐rich plume at least 58 km high.

Discovery of the Largest Historic Silicic Submarine Eruption [PDF]

Eos, Transactions American Geophysical Union, 2014
It was likely twice the size of the renowned Mount St. Helens eruption of 1980 and perhaps more than 10 times bigger than the more recent 2010 Eyjafjallajökull eruption in Iceland. However, unlike those two events, which dominated world news headlines, in 2012 the daylong submarine silicic eruption at Havre volcano in the Kermadec Arc, New Zealand ...

SANTORY: SANTORini’s Seafloor Volcanic ObservatorY

Frontiers in Marine Science, 2022
Submarine hydrothermal systems along active volcanic ridges and arcs are highly dynamic, responding to both oceanographic (e.g., currents, tides) and deep-seated geological forcing (e.g., magma eruption, seismicity, hydrothermalism, and crustal ...

Degassing history of water, sulfur, and carbon in submarine lavas from Kilauea volcano, Hawaii [PDF]

, 1991
Major, minor, and dissolved volatile element concentrations were measured in tholeiitic glasses from the submarine portion (Puna Ridge) of the east rift zone of Kilauea Volcano, Hawaii.

Explosive Submarine Eruptions: The Role of Condensable Gas Jets in Underwater Eruptions

Journal of Geophysical Research: Solid Earth, 2021
AbstractIn explosive submarine eruptions, volcanic jets transport fragmented tephra and exsolved gases from the conduit into the water column. Upon eruption the volcanic jet mixes with seawater and rapidly cools. This mixing and associated heat transfer ultimately determines whether steam present in the jet will completely condense or rise to breach ...

Models of Hawaiian volcano growth and plume structure: Implications of results from the Hawaii Scientific Drilling Project [PDF]

, 1996
The shapes of typical Hawaiian volcanoes are simply parameterized, and a relationship is derived for the dependence of lava accumulation rates on volcano volume and volumetric growth rate.

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.
