Bubble nucleation in magmas: a dominantly heterogeneous process?

T Shea - Journal of Volcanology and Geothermal Research, 2017‏ - Elsevier
Bubble nucleation is at the heart of magma ascent and degassing. Nucleation kinetics
control how easily a magma exsolves its volatiles, and thereby its explosivity close to the …

Why deep-water eruptions are so different from subaerial eruptions

RAF Cas, JM Simmons - Frontiers in Earth Science, 2018‏ - frontiersin.org
Magmas erupted in deep-water environments (> 500 m) are subject to physical constraints
very different to those for subaerial eruptions, including hydrostatic pressure, bulk modulus …

Plinian and subplinian eruptions

R Cioni, M Pistolesi, M Rosi - The encyclopedia of volcanoes, 2015‏ - Elsevier
The term “plinian” encompasses powerful explosive eruptions characterized by the quasi-
steady, hours-long, high-speed discharge into the atmosphere of a high-temperature …

Physical properties of pyroclastic density currents: relevance, challenges and future directions

TJ Jones, F Beckett, B Bernard, ECP Breard… - Frontiers in Earth …, 2023‏ - frontiersin.org

Transitions between fall phases and pyroclastic density currents during the AD 79 eruption at Vesuvius: building a transient conduit model from the textural and …

T Shea, L Gurioli, BF Houghton - Bulletin of Volcanology, 2012‏ - Springer
The magmatic phase of the AD 79 eruption of Vesuvius produced alternations of fall and
pyroclastic density current (PDC) deposits. A previous investigation demonstrated that the …

Sediment waves and the gravitational stability of volcanic jets

JT Gilchrist, AM Jellinek - Bulletin of Volcanology, 2021‏ - Springer
It is increasingly recognized that the gravitational stability of explosive eruption columns is
governed by complex ash-pumice-gas (multiphase) interactions as well as the mechanics of …

Insights into eruption dynamics from textural analysis: the case of the May, 2008, Chaitén eruption

F Alfano, C Bonadonna, L Gurioli - Bulletin of Volcanology, 2012‏ - Springer
Abstract The May, 2008, Chaitén (southern Chile) eruption was characterized by several
explosive events, each associated with plumes which reached up to about 19 km above sea …
