Volatiles dissolved in silicic magma at depth exsolve as the magma nears the surface and
cause an increase in viscosity of the magma. A model of a volcanic conduit within an elastic …

In this study, we show how veined lithospheric mantle is involved in the genesis of
ultrapotassic magmatism in cratonic settings. We conducted high pressure experiments to …

Nevados de Chillán volcanic complex (NChVC) is one of the most active volcanoes in Chile
having 4 eruptive episodes within the previous century. All of this activity has been …

Small-volume proximal-summit eruptions, sometimes with only little precursors, are common
at Piton de la Fournaise (La Reunion Island, France). Their eruptive style ranges from …

The 23 November 2013 lava fountain at Etna volcano was the most explosive of the last 44
episodes that have occurred at Etna in 2011–2013. We infer the total magma volume …

Estimates of the volatile budgets for volcanic eruptions are often based on volatile
concentrations measured in melt inclusions (MIs) versus groundmass glass. Here, we …

The interactions between two deformable bubbles are studied in order to determine the
effects of deformation on bubble dynamics and to determine the limits in which the effects of …

Multiphase flow in basaltic volcanic conduits is investigated using analog experiments and
theoretical approaches. Depending on gas supply, large gas bubbles (gas slugs) may rise …

Abstract Extensive vertical deformation (> 4.5 m) observed at Sierra Negra volcano
Galápagos, Ecuador, between 1992 and the 2005 eruption led scientists to hypothesize that …

It is commonly accepted that effusive activity emplaces the main emitted magmatic volume in
basaltic shield volcanoes. At Piton de La Fournaise (La Réunion Island, France), eruptive …
