Volcano collapse along the Aleutian Ridge (western Aleutian Arc) [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2011
The Aleutian Ridge, in the western part of the Aleutian Arc, consists of a chain of volcanic islands perched atop the crest of a submarine ridge with most of the active Quaternary stratocones or caldera-like volcanoes being located on the northern ...

Fire in the sea - Growth and destruction of submarine volcanoes [PDF]

open access: yes, 2013
The appearance of a steaming volcano close to the sea surface represents a rare but spectacular geological event, because the birth of a new volcano vividly illustrates the steady yet piecemeal growth of the Earth’s crust; and its simultaneous ...

Submarine explosive activity and ocean noise generation at Monowai Volcano, Kermadec Arc: constraints from hydroacoustic T-waves [PDF]

open access: yes, 2016
Submarine volcanic activity is difficult to detect, because eruptions at depth are strongly attenuated by seawater. With increasing depth the ambient water pressure increases and limits the expansion of gas and steam such that volcanic eruptions tend to ...

Research progress on the in-situ monitoring technologies of marine geohazards

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao, 2022
Marine geohazards pose a major threat to the population and marine economic development of coastal cities. The expansion of construction of coastal port channels, submarine pipelines, optical cables, and marine platform foundations means that the risk of

The 1998 eruption of Axial Seamount: New insights on submarine lava flow emplacement from high‐resolution mapping

open access: yesGeochemistry, Geophysics, Geosystems, 2013
Axial Seamount, an active submarine volcano on the Juan de Fuca Ridge at 46°N, 130°W, erupted in January 1998 along 11 km of its upper south rift zone.

Patterns of Fine Ash Dispersal Related to Volcanic Activity at West Mata Volcano, NE Lau Basin

open access: yesFrontiers in Marine Science, 2019
Extensive deep (>1500 m) non-hydrothermal ash-rich plumes were present in the water column surrounding West Mata submarine volcano (NE Lau basin) during eruptive phases, but were absent when West Mata was quiescent.

Deep drilling into a Hawaiian volcano [PDF]

open access: yes, 2001
Hawaiian volcanoes are the most comprehensively studied on Earth. Nevertheless, most of the eruptive history of each one is inaccessible because it is buried by younger lava flows or is exposed only below sea level.

Anomalous crustal movements with low seismic efficiency - Campi Flegrei, Italy and some examples in Japan [PDF]

open access: yes, 2002
Campi Flegrei is a unique volcanic region located near Naples, Italy. Anomalous crustal movements at Pozzuoli in Campi Flegrei have been documented since the Roman period.

Pumice rafts in the global ocean: a remote sensing assessment

open access: yesGIScience & Remote Sensing
Pumice rafts mainly originate from submarine volcanic eruptions, which can be captured by ocean color satellite sensors as shown in several case studies. On a global scale, however, there is a lack of systematic evaluation using consistent algorithms and

The 2011 submarine volcanic eruption in El Hierro (Canary Islands) [PDF]

open access: yesGeology Today, 2012
Forty years after the Teneguía Volcano (La Palma, 1971), a submarine eruption took place off the town of La Restinga, south of El Hierro, the smallest and youngest island of the Canarian Archipelago. Precursors allowed an early detection of the event and its approximate location, suggesting it was submarine.
