The scientific investigation of magma fragmentation and the development of experiments to
constrain and quantify its mechanisms, dynamics, efficiency and products was ushered in …

Viscosity is the single most important physical property governing the formation, transport
and eruption of naturally occurring silicate melts and magmas. Silicate melt viscosity is of …

Abstract The 2021 Tajogaite eruption of Cumbre Vieja (La Palma, Spain) was typified by the
emission of low viscosity lavas that flowed at high velocities and inundated a large area. We …

Explosivity in erupting volcanoes is controlled by the degassing dynamics and the viscosity
of the ascending magma in the conduit. Magma crystallisation enhances both …

We apply dynamical models to estimate the rheological properties of magma and lava
during the 2021–22 eruption of La Soufrière Volcano, St Vincent. Analysis of the …

Igneous processes involve multiphase magmas, and the rate at which these processes
operate is tightly controlled by multiphase rheology. The rheology of magmatic suspensions …

In active volcanic environments magmas that ascend within the conduit and erupt at the
surface as lava flows experience physico-chemical perturbations related to temperature …

Dyke propagation is a mechanism for more rapid ascent of felsic magmas through the crust
than is possible via diapirs or percolative flow. As it ascends, the magma undergoes …

The pāhoehoe—'a 'ā morphological transition involves a change in the rheological response
of the magmatic suspension from pure viscous to complex rheological behavior, resulting in …

One of the most intriguing and (from the point of view of modeling) poorly understood
aspects of geomaterial mechanics is strain localization. Strain localization is a common …
