Explosive eruptions are the most powerful and destructive type of volcanic activity. These
eruptions are characterized by magma fragmentation, the process through which a bubbly or …

Volcanic eruptions can be either slow outpourings of lava or explosive ejections of
fragmented rock. In his Perspective, Dingwell discusses the physical and chemical …

Recent numerical models and analog shock tube experiments show that disequilibrium
degassing during magma ascent may lead to violent vesiculation very near the surface. In …

Understanding gas-magma dynamics in volcanic conduits and linking them with the
associated geophysical signals at the surface is of fundamental importance in monitoring …

With the aim to enhance interpretation of fragmentation mechanisms during explosive
volcanism from size and shape characteristics of pyroclasts experimental studies have been …

In an explosive eruption, the atmospheric column dynamics depend strongly on the mass
fraction of gas in the erupting mixture, which is fixed by fragmentation in the volcanic conduit …

The experimental approach has become a major tool increasingly used by volcanologists in
recent decades to investigate the physics of eruptive processes in complement to field and …

An experimental study of H 2 O exsolution, bubble growth and microlite crystallisation during
ascent (decompression) of silicic magmas in the volcanic conduit is presented. Isobaric and …

Analysis of the behavior of viscous magma under short-term tensile stresses demonstrates
that the strain rates anticipated in the eruptive stages of collapse-related events may be high …

We review observations of bubble size distributions (BSDs) generated during explosive
volcanic eruptions and laboratory explosions, as inferred from vesicle size distributions …
