Deep Submarine Pyroclastic Eruptions
1983Abstract Published experimental, thermodynamic, and other geochemical data on H2O-bearing silicic melts are used to obtain relationships which show that: (1) the rate of exsolution of H2O (vesiculation) from silicic magmas that contain more than a few tenths of 1 wt percent H2O is sufficiently rapid to contribute to the explosivity of

Submarine Fallout Tephra from Subaerial Eruptions
1984Following classic studies of deep sea exploration in the 1940’s (Bramlette and Bradley, 1942; Neeb, 1943; Norin, 1948), a great deal of modern research has been done on marine ash layers, much of which is summarized by Kennett (1981). Marine ash layers were originally studied for their value as widespread stratigraphic markers, but deep penetration of ...

The 1989 submarine eruption off eastern Izu Peninsula, Japan: ejecta and eruption mechanisms
Bulletin of Volcanology, 1991The submarine eruption of a new small knoll, which was named “Teishi knoll”, off eastern Izu Peninsula behind the Izu-Mariana arc occurred in the evening of 13 July 1989. This is the first historic eruption of the Higashi-Izu monogenetic volcano group. The eruption of 13 July followed an earthquake swarm near Ito city starting on 30 June.

Lava balloons—peculiar products of basaltic submarine eruptions
Bulletin of Volcanology, 2012Between December 1998 and April 2001, a submarine basaltic eruption occurred west of Terceira Island, Azores (Portugal) in water depths between 300 and 1,000 m. Physical evidence for the eruption was provided by the periodic occurrence of hot lava “balloons” floating on the sea surface.

Reports of a submarine eruption off New Zealand in 1877
New Zealand Journal of Geology and Geophysics, 1958Summary Submarine eruptions were reported on 1 December 1877 near East Cape. They were probably not of volcanic origin, and may have been a tsunami.

Ash generation and transport during explosive submarine eruptions
Submarine volcanic eruptions can form subaerial plumes that frequently reach the troposphere or even the stratosphere. Despite this, the impact of submarine eruptions on ash transport and related hazards remains unclear due to a lack of clear geological record.Mathieu Colombier +13 more
