Abstract The 2000 AD eruption of Miyakejima was characterized by a series of phreatomagmatic eruptions from the subsiding caldera. Six major eruptive events occurred, and they can be divided into the first and second periods separated by a 25-day hiatus. The phreatomagmatic eruptions produced a total of ~ 2 × 1010 kg of tephra, which mainly comprised

Abstract In 1949, a 5-week-long magmatic and phreatomagmatic eruption took place along the active volcanic ridge of La Palma (Canary Islands). Two vents, Duraznero and Hoyo Negro, produced significant pyroclastic deposits. The eruption began from Duraznero vent, which produced a series of deposits with an upward decrease in accidental fragments and ...

The model of an eruptive column produced by phreatomagmatic explosions
Journal of Volcanology and Seismology, 2017This paper presents the results from the simulation of a phreatomagmatic eruption, in which the formation of the eruptive column is controlled by interaction between magma and water or ice. The process leads to intensive fragmentation of the magma and to mixing of ash and steam with ambient air.

Ascent dynamics of large phreatomagmatic eruption clouds: The role of microphysics
Journal of Geophysical Research: Solid Earth, 2012We examine the impact of abundant surface water interaction on the development of volcanic clouds from large‐scale (>108 kg s−1 magma) phreatomagmatic eruptions, presenting the first 2‐D large‐eddy simulations of “wet” volcanic plumes that incorporate the effects of microphysics.

The 1630 AD eruption on the island of Sa˜o Miguel in the Azores took place from a vent in the southern part of the 7 × 5 km caldera of Furnas volcano. Precursory seismic activity occurred at least 8 hours before the eruption began and was felt over 30 km away.

Impure coolants and interaction dynamics of phreatomagmatic eruptions
Journal of Volcanology and Geothermal Research, 1996Abstract Phreatomagmatic eruptions resulting from interaction of magma with groundwater are common in many terrestrial settings, and their explosivity is widely accepted to result from fuel-coolant interaction (FCI) processes. Relatively little attention has been given to the precise nature of the volcanic settings in which phreatomagmatic FCI's take

This paper documents a phreatomagmatic flank eruption that occurred 18 700 ± 100 a BP, on the lower north‐eastern slope of Etna during the Ellittico volcano activity, which produced fall and surge deposits. This type of eruption is connected to a sedimentary basement ridge at Etna.

Abstract The 2500 BP Hverfjall eruption in northern Iceland produced pyroclastic and effusive deposits of widely different characteristics along the length of the eruptive fissure. The southern half of the fissure was located in a shallow lake, whereas the northern part of the fissure extended onto dry land.
