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 …

Magmatic fragmentation during explosive eruptions consumes a significant amount of
energy by the creation of new surface via fracturing. This process reduces the energy that …

Products of magma fragmentation can pose a severe threat to health, infrastructure,
environment, and aviation. Systematic evaluation of the mechanisms and the consequences …

The dynamics of magma fragmentation is a controlling factor in the behavior of explosive
volcanic eruptions. If porous magma is sufficiently decompressed, a fragmentation front …

It is currently impractical to measure what happens in a volcano during an explosive
eruption, and up to now much of our knowledge depends on theoretical models. Here we …

The propagation speed of a fragmentation front, combined with the ascent velocity of magma
is, in all likelihood, a controlling factor in the dynamics of explosive volcanic eruptions. Direct …

Pyroclast ejection during explosive volcanic eruptions occurs under highly dynamic
conditions involving great variations in flux, particle sizes, and velocities. This variability …

The impact of explosive volcanic plumes on climate and on air traffic strongly depends on
the concentration and grain-size distribution (GSD) of pyroclastic fragments injected into the …

Explosive volcanic eruptions are among the most energetic events on Earth. The hazard to
surrounding populations and aviation is controlled by the concentration and size of particles …

Liquid explosions, generated by rapid degassing of strongly supersaturated liquids, have
been investigated in the laboratory with a view to understanding the basic physical …
