Eos, Transactions American Geophysical Union, 1989 An episode of submarine volcanic activity in the northern Mariana Islands, in the northwest Pacific Ocean, has been recorded by the Wake Island hydrophone array. F. Oliveira, C. McCreery and D. Walker of the Hawaii Institute of Geophysics in Honolulu collected the data (see figure) while they were installing upgraded recording equipment for the array ...

Anatomy of an active submarine volcano [PDF]
Geology, 2014 Most of the magma erupted at mid-ocean ridges is stored in a mid-crustal melt lens that lies at the boundary between sheeted dikes and gabbros. Nevertheless, images of the magma pathways linking this melt lens to the overlying eruption site have remained elusive.

Stratigraphy of the Hawai'i Scientific Drilling Project core (HSDP2): Anatomy of a Hawaiian shield volcano [PDF]
, 2007 The Hawai'i Scientific Drilling Project (HSDP2) successfully drilled ∼3.1 km into the island of Hawai'i. Drilling started on Mauna Loa volcano, drilling 247 m of subaerial lavas before encountering 832 m of subaerial Mauna Kea lavas, followed by 2019 m ...

Global perturbation of stratospheric water and aerosol burden by Hunga eruption
Communications Earth & Environment, 2022 The eruption of the submarine Hunga volcano in January 2022 led to a 13% increase in global stratospheric water mass and a 5-fold increase in stratospheric aerosol load, according to satellite data complemented by ground-based observations and ...

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.

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.

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.

Numerical modelling of mud volcanoes and their flows using constraints from the Gulf of Cadiz [PDF]
, 2003 It is estimated that the total number of submarine mud volcanoes is between 1000 and 100 000. Because many are associated with greenhouse gases, such as methane, it is argued that the global flux of these gases to the atmosphere from the world’s ...

Mineralized microbes from Giggenbach submarine volcano [PDF]
Journal of Geophysical Research: Solid Earth, 2008 The Giggenbach submarine volcano, which forms part of the Kermadec active arc front, is located ∼780 km NNE of the North Island of New Zealand. Samples collected from chimneys associated with seafloor hydrothermal vents on this volcano, at a depth of 160–180 m, contain silicified microbes and microbes entombed in reticular Fe‐rich precipitates.
