Submarine Volcano - an overview | ScienceDirect Topics
2006年1月22日 · A submarine volcano is defined as a volcano that erupts beneath the sea surface, with most of them located along mid-ocean ridges. These underwater volcanoes can develop into islands over time and are responsible for …
Worldwide distribution of submarine mud volcanoes and …
2000年6月15日 · By combining the estimate of the amount of methane gas hydrate accumulations associated with a single submarine mud volcano with the estimated number of hydrate bearing mud volcanoes worldwide, the total global amount of methane in mud volcanic gas hydrates may be estimated at n×10 10 –10 12 m 3. This estimate is preliminary, yet highlights ...
The Keelung Submarine Volcano in the near-shore area of …
2017年11月1日 · The Keelung Submarine Volcano belongs to the NTVZ and its diameter is ∼6 km. Associated with the Keelung Submarine Volcano, volcanic gases constituting gas flares in the seawater column are emitted persistently out of seafloor. Most of the gas flares concentrate on the western border of the volcanic cone.
In situ carbon isotopic exploration of an active submarine volcano
2018年4月1日 · The development and deployment of an in situ laser spectrometer for combined carbon isotope analysis of CO 2 and CH 4 sheds new light on the nature of carbon fluxes at the KEJ submarine arc volcano. Mean δ 13 C CO2 values for the KEJ vents exhibiting the largest fluid and gas fluxes (Champagne and Shrimp Vents) fall generally within the upper ...
Underwater records of submarine volcanic activity: El Hierro …
2020年12月15日 · This event was triggered by an unusually large-scale eruption, which produced an acoustic signal 10 times greater than the normal background level of the eruptive activity. It was the first documented sequence of a submarine volcano for an intrusion-eruption-landslide event (Chadwick et al., 2012).
The 6–8 Aug 2019 eruption of ‘Volcano F’ in the Tofua Arc, Tonga
2019年8月8日 · The submarine arc volcano is listed as #243091 in the database of the Global Volcanism Program (2013) and was the source of a previous pumice-raft producing eruption on 27–28 September 2001 (Bryan et al., 2004; Global Volcanism Program, 2019).
Submarine volcanoes along the Aegean volcanic arc
2013年6月19日 · The submarine hydrothermal activity indicates the ongoing volcanic process both onshore and offshore. The volcanoes form a neotectonic graben with normal faulting, overprinted by subvertical strike–slip structures. The geometry of each volcanic group and the volume of the extruded rocks are different through time. It is interesting to compare the …
Source of the tsunami generated by the 1650 AD eruption of …
2016年7月15日 · The 1650 eruption of Kolumbo submarine volcano, 7 km north-east of Santorini (Fig. 1), generated a destructive tsunami in the Aegean Sea (Fouqué, 1879). The source of the tsunami(s) is not clarified and its magnitude has been discussed (Dominey-Howes et al., 2000, Nomikou et al., 2014). Download : Download high-res image (2MB)
Volcano-tectonic evolution of the polygenetic Kolumbo submarine …
2015年1月15日 · 3D-architecture of an explosive submarine volcano shown for the first time by reflection seismic data interpretation. Evidence for abundant explosive underwater volcanism in the southern Aegean Sea. Hosting Anydros basin (southern Aegean Sea) opened incrementally north-west to south-east during four major pulses.
Morphology, petrology and geochemistry of submarine volcanoes …
2023年4月1日 · Along-latitude variation of whole rock chemical composition of each submarine volcano and depression. The red solid and broken lines are reference data from the rhyolites in middle Okinawa Trough (Shinjo and Kato, 2000) and the rhyolite in the southern volcanic front (Chung et al., 2000), respectively. (For interpretation of the references to ...
