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 ...

Fish mortality associated to volcanic eruptions in the Canary Islands
Frontiers in Marine Science, 2023 The Canary Islands are an active volcanic archipelago. In the last decade, volcanic activity has occurred twice on the youngest and western most islands: El Hierro (submarine eruption) in 2011-12, and La Palma (subaerial eruption) in 2021.

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 ...

Strong geochemical anomalies following active submarine eruption offshore Mayotte [PDF]
Chemical Geology, 2023 Submarine volcanic activity releases large amounts of gases and metals in the water column, affecting biogeochemical cycles and ecosystems at a regional and local scale. In 2018, Fani Maoré submarine volcano erupted 50 km offshore Mayotte Island (Comoros Archipelago, Indian Ocean).

Glass in the submarine section of the HSDP2 drill core, Hilo, Hawaii [PDF]
, 2004 The Hawaii Scientific Drilling Project recovered ~3 km of basalt by coring into the flank of Mauna Kea volcano at Hilo, Hawaii. Rocks recovered from deeper than ~1 km were deposited below sea level and contain considerable fresh glass. We report electron

Submarine landslide megablocks show half of Anak Krakatau island failed on December 22nd, 2018
Nature Communications, 2021 The authors here present a detailed reconstruction of the landslide mass following the 2018 eruption of Anak Krakatau. Bathymetry data reports the volume of the collapsed submarine flank to be much larger than previously reported.

The first ultra-high resolution Digital Terrain Model of the shallow-water sector around Lipari Island (Aeolian Islands, Italy) [PDF]
, 2015 Very high resolution bathymetric map obtained through multibeam echosounders data are crucial to generate accurate Digital Terrain Models from which the morphological setting of active volcanic areas can be analyzed in detail. Here we show and discuss
