Submarine Eruption of Myojin Reef

Journal of Geography (Chigaku Zasshi), 1953
An under sea volcanic eruption was discovered by the No. 11 Myojin-maru, fishing boat, at the point of 31° 56.7' N, 140° 00.5' F, at-cut 5 miles ENE of the Bayernaise Reefs, on the morning of Sept 17, 1952. The volcanic islet was named as the Myojin Reef after the fishing boat.

Noble gas signals in corals predict submarine volcanic eruptions [PDF]

Chemical Geology, 2018
Deep-water corals growing in close proximity to the 2011 submarine eruption at Tagoro (El Hierro Island; Canary Archipielago, Spain) have revealed their ability to record the magmatic helium (3He) signal during a period of months prior to the eruption with magmatic 3He/4He ratios of 3.6-5.0 RA This is similar to the range of He isotope

Subaqueous landslides at the distal basin of Lago Nahuel Huapi (Argentina): Towards a tsunami hazard evaluation in Northern Patagonian lakes [PDF]

, 2018
The May 22nd, 1960 Valdivia earthquake, Chile (Mw 9.5) triggered a series of subaqueous mass-wasting processes (debris flows and slides) in Lago Nahuel Huapi (Argentina), generating a tsunami-like wave that hit the coasts of San Carlos de Bariloche ...

Large‐Scale Submarine Sediment Waves at Macauley Caldera Volcano: In Situ Evidence of High‐Flux, Syn‐Eruptive Submarine Transport

Geochemistry, Geophysics, Geosystems
Two sediment cores were collected from a submarine sediment wave field on the flank of Macauley volcano. Combined with seismic reflection surveys and numerical modeling, we present an integrated model of the formation of large‐scale, eruption‐fed ...

The 2019–2020 volcanic eruption of Late’iki (Metis Shoal), Tonga

Scientific Reports, 2022
Late’iki (previously known as Metis Shoal) is a highly active volcano in the Tofua arc with at least four temporary island-building eruptions and one submarine eruption in the last 55 years.

Volcano-tectonic structures of Mayotte’s upper submarine slope: insights from high-resolution bathymetry and in-situ imagery from a deep-towed camera

Comptes Rendus. Géoscience, 2022
Unlike subaerial volcanic activity, deep submarine eruptions are difficult to detect, observe and monitor. The objective of this paper is to describe a large and complex volcanic region, named the Horseshoe area, recently discovered at ${\sim }$1500 m ...

Submarine cores record magma evolution toward a catastrophic eruption at Kikai Caldera

Communications Earth & Environment
Magma evolution toward a caldera-forming eruption remains uncertain in many cases owing to the lack of successive volcanic records before catastrophic eruptions.

Impact of submarine volcanic versus hydrothermal activity onto the strontium and lithium isotopic signatures of the water column (TONGA)

Frontiers in Marine Science
During the TONGA cruise (2019), seawater samples were collected to assess the effect of volcanic eruption versus submarine hydrothermal system on the water column.

Multi-stage volcanic island flank collapses with coeval explosive caldera-forming eruptions

Scientific Reports, 2018
Volcanic flank collapses and explosive eruptions are among the largest and most destructive processes on Earth. Events at Mount St. Helens in May 1980 demonstrated how a relatively small (300 km3), but can also occur in complex multiple stages.
