When considering the rheology of a suspension the fundamental physical aspect to be
quantified is the redistribution of strain between the deformable matrix fraction of the …

The viscosity of solid phase containing heterogeneous silicate melts is discussed in this
review. The crucial parameters characterizing silicate melt structure are first presented, ie …

Pore connectivity is a measure of the fraction of pore space (vesicles, voids or cracks) in a
material that is interconnected on the system length scale. Pore connectivity is …

Our ability to forecast volcanic hazards at active volcanoes stems from our knowledge of
parameters affecting eruption dynamics. Persistent activity displayed by basaltic volcanic …

In volcanic regions, reliable estimates of mechanical properties for specific volcanic events
such as cyclic inflation-deflation cycles by magmatic intrusions, thermal stressing, and high …

The eruption style of silicic magmas is affected by the loss of gas (outgassing) during ascent.
We investigate outgassing using a numerical model for one-dimensional, two-phase, steady …

Magmas may flow or break depending on their deformation rate. The transition between
such viscous and brittle behavior controls the style of volcanic eruptions. While the brittle …

Simple shear deformation experiments on three‐phase, hydrous, haplogranitic magmas,
composed of quartz crystals (24–65 vol.%), CO2‐rich gas bubbles (9–12 vol.%) and melt in …

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

Abstract Nyiragongo (Democratic Republic of Congo) erupts fluid, fast-moving, foidite lavas.
Nearby Nyamuragira frequently erupts less mobile tephrite lavas. Nyamuragira flows rarely …
