Magma fragmentation is the breakup of a continuous volume of molten rock into discrete
pieces, called pyroclasts. Because magma contains bubbles of compressible magmatic …

Eruptive column models are powerful tools for investigating the transport of volcanic gas and
ash, reconstructing past explosive eruptions, and simulating future hazards. However, the …

This study compares and evaluates one-dimensional (1D) and three-dimensional (3D)
numerical models of volcanic eruption columns in a set of different inter-comparison …

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 …

In explosive submarine eruptions, volcanic jets transport fragmented tephra and exsolved
gases from the conduit into the water column. Upon eruption the volcanic jet mixes with …

Explosive volcanic eruptions can inject sulfur dioxide (SO2) into the stratosphere to form
aerosol particles that modify Earth's radiation balance and drive surface cooling. Eruptions …

We have measured grain size distributions of the results of laboratory decompression
explosions of volcanic rock. The resulting distributions can be approximately represented by …

Volcanic tephra fall deposits, which form during explosive eruptions, are commonly
characterized in terms of their thickness and grainsize. While significant efforts have been …

Turbulent buoyant plumes moving through density stratified environments transport large
volumes of fluid vertically. Eventually, the fluid reaches its neutral buoyancy level at which it …

The mass eruption rate feeding a volcanic plume is commonly estimated from its maximum
height. Winds are known to affect the column dynamics causing bending and hence …
