Relating vesicle shapes in pyroclasts to eruption styles [PDF]
Vesicles in pyroclasts provide a direct record of conduit conditions during explosive volcanic eruptions. Although their numbers and sizes are used routinely to infer aspects of eruption dynamics, vesicle shape remains an underutilized parameter.

The 2021 eruption at Tajogaite (Cumbre Vieja) volcano (La Palma, Spain) was characterized by Strombolian eruptions, Hawaiian fountaining, white gas-dominated and grey ash-rich plumes, and lava effusion from multiple vents.

Modelling of bubble nucleation in trachy-phonolitic magmas: implications for the dynamics of ash-rich eruptions [PDF]
Nucleation of water gas bubbles in trachyphonolitic magmatic melts has been investigated integrating theory and numerical modelling with decompression experiments and analysis of natural ash samples of explosive eruptions.

The Explosive Activity of the 2021 Tajogaite Eruption (La Palma, Canary Islands, Spain)
The explosive activity of the 2021 Tajogaite eruption eludes pigeonholing into well‐defined eruption styles, with a variety of pyroclast ejection modes occurring both alternately and simultaneously at multiple vents.

Syneruptive magma decompression rate is thought to play a key role in controlling the explosivity of basaltic eruptions due to its influence on bubble formation and migration within the conduit [1–3].

Stratigraphy and textural characteristics of the 1982–83 tephra of Galunggung volcano (Indonesia): implications for volcanic hazards [PDF]
91.40.RsThe Galunggung volcano in western Java (Indonesia) was the site of historical activity in 1822, 1894, 1918, and 1982–83, located in a pre-historical horseshoe-shaped caldera.

Leachate analyses of volcanic ashes from Stromboli volcano: A proxy for the volcanic gas plume composition? [PDF]
Many volcanoes show a change in chemical composition of the gas phase prior to periods of eruptive activity. Fine‐grained tephra erupted from active vents and transported through volcanic plumes can adsorb, and therefore rapidly scavenge, volatile ...

Maars to calderas. End-members on a spectrum of explosive volcanic depressions [PDF]
We discuss maar-diatremes and calderas as end-members on a spectrum of negative volcanic landforms (depressions) produced by explosive eruptions (note—we focus on calderas formed during explosive eruptions, recognizing that some caldera types are not ...
