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

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 …

Explosive volcanic eruption requires that magma fragments into discrete parcels. Silicic
magma can fragment through brittle failure or other processes that depend on the …

The distinguishing characteristic of explosive volcanic eruptions is the transformation of
either liquid or solid magma into a mixture of gas and small particles, a process referred to in …

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

Basalt is the most ubiquitous magma on Earth, erupting typically at intensities ranging from
quiescently effusive to mildly explosive. The discovery of highly explosive Plinian eruptions …

In response to rapid decompression, porous magma may fragment explosively. This occurs
when the melt can no longer withstand forces exerted upon it due to the overpressure in …

The eruption of basaltic magmas dominates explosive volcanism on Earth and other planets
within the Solar System. The mechanism through which continuous magma fragments into …

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 …

Fragmentation processes in eruptions are commonly contrasted as phreatomagmatic or
magmatic; the latter requires only fragmentation of magma without external intervention, but …
