Eruption Sequences and Characteristics of Weizhou Island Volcano, Guangxi Province, South of China
Frontiers in Earth Science, 2021 Weizhou island, located in the north margin of the South China Sea (SCS), is characterized by multi-stage volcanism, several eruption styles and eruption craters, and is also the youngest Quaternary volcanic island in China.

Reconciling bubble nucleation in explosive eruptions with geospeedometers [PDF]
Nature Communications, 2021 AbstractMagma from Plinian volcanic eruptions contains an extraordinarily large numbers of bubbles. Nucleation of those bubbles occurs because pressure decreases as magma rises to the surface. As a consequence, dissolved magmatic volatiles, such as water, become supersaturated and cause bubbles to nucleate. At the same time, diffusion of volatiles into

Lightning and electrical activity during the Shiveluch volcano eruption on 16 November 2014 [PDF]
Natural Hazards and Earth System Sciences, 2016 According to World Wide Lightning Location Network (WWLLN) data, a sequence of lightning discharges was detected which occurred in the area of the explosive eruption of Shiveluch volcano on 16 November 2014 in Kamchatka.

Highly explosive basaltic eruptions driven by CO2 exsolution
Nature Communications, 2021 Mechanisms that drive highly explosive eruptions of low-viscosity magmas, such as at Sunset Crater volcano, remain uncertain. Here, the authors present evidence for an exsolved CO2 phase ~15 km beneath Sunset Crater that was the critical driver of rapid ...

Scientific Reports, 2023 We present a systematic evaluation of the perturbation to the stratosphere from an explosive volcanic eruption injecting sulfur dioxide into the atmosphere, as a function of latitude, season, and injection gas halogen content in a chemistry-climate state

Will subglacial rhyolite eruptions be explosive or intrusive? Some insights from analytical models. [PDF]
, 2007 Simple analytical models of subglacial eruptions are presented, which simulate evolving subglacial cavities and volcanic edifices during rhyolitic eruptions beneath temperate glaciers.

Nature Communications, 2022 The 2020 – 2021 eruption of La Soufrière volcano transitioned from an effusive to explosive eruption style. Here the authors show that input from multiple monitoring datasets and an evolving conceptual model were key to anticipating and responding to the

Magma volume, volatile emissions, and stratospheric aerosols from the 1815 eruption of Tambora [PDF]
, 2004 We suggest that the Tambora 1815 eruption was smaller than previously thought, yielding 30–33 km3 of magma. Valuable insight into the eruption is gained by comparing it to the much smaller 1991 Pinatubo event, which had a similar eruption style and rate.

Discriminating Types of Volcanic Electrical Activity: Toward an Eruption Detection Algorithm
Geophysical Research Letters, 2022 We present a method for classification of the two distinct types of electrical activity that occur during an explosive volcanic eruption: vent discharges and lightning.
