Vulcanian eruption mechanisms [PDF]
Nature, 1979 Application of a newly developed theory to volcanological observations of explosive eruptions shows that previous estimates of pre-explosion gas pressures may be overestimated by an order of magnitude.

Frontiers in Earth Science, 2021 Signals of volcanic unrest do not usually provide insights into the timing, size and style of future eruptions, but detailed analysis of past eruptions may uncover patterns that can be used to understand future eruptive behavior.

Infrasonic precursors to a Vulcanian Eruption at Sakurajima Volcano, Japan [PDF]
Geophysical Research Letters, 1999 The May 1998 eruption sequence of Sakurajima Volcano was monitored by ten infrasonic stations, ten seismometers, and a video camera. During this seismo‐acoustic experiment, we recorded hundreds of infrasonic tremor and long‐period events associated with seismic signals, and observed a progression from relative quiescence to a Vulcanian eruption.

Can vesicle size distributions assess eruption intensity during volcanic activity? [PDF]
Solid Earth, 2013 We studied three-dimensional (3-D) vesicle size distributions by X-ray microtomography in scoria collected during the relatively quiescent Phase II of the April–May 2010 eruption at Eyjafjallajökull volcano, Iceland.

Forecasting explosions at Sinabung Volcano, Indonesia, based on SO2 emission rates
Frontiers in Earth Science, 2022 Dome-building volcanic eruptions are often associated with frequent Vulcanian explosions, which constitute a substantial threat to proximal communities. One proposed mechanism driving such explosions is the sealing of the shallow volcanic system followed

Behavior of Sn-3.0Ag-0.5Cu solder/Cu fluxless soldering via Sn steaming under formic acid atmosphere
Journal of Materials Research and Technology, 2022 Formic acid (FA) atmosphere is promising to achieve chemical reduction at the oxidized surfaces of the solder and matrix material during soldering, replacing chemical flux being challenging as the continuous decrease in the pitch of solder bump in a ...

Probabilistic volcanic hazard assessment at an active but under-monitored volcano: Ceboruco, Mexico
Journal of Applied Volcanology, 2022 A probabilistic volcanic hazard assessment (PVHA) for Ceboruco volcano (Mexico) is reported using PyBetVH, an e-tool based on the Bayesian Event Tree (BET) methodology. Like many volcanoes, Ceboruco is under-monitored.

SO2 and tephra emissions during the December 22, 2018 Anak Krakatau eruption
Volcanica, 2019 On December 22, 2018 the south-western flank of Anak Krakatau collapsed into the sea, removing 93.8 × 106 m3 of subaerial lavas, and generated a tsunami.

Frontiers in Earth Science, 2023 Volatiles exert a critical control on volcanic eruption style and in turn impact the near source environment and global climate. La Soufrière de Guadeloupe in the Lesser Antilles has been experiencing volcanic unrest since 1992, increasing to a peak in ...
