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.

The Explosive Activity of the 2021 Tajogaite Eruption (La Palma, Canary Islands, Spain)

Geochemistry, Geophysics, Geosystems, 2023
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.

Can nanolites enhance eruption explosivity? [PDF]

Geology, 2020
Abstract Degassing dynamics play a crucial role in controlling the explosivity of magma at erupting volcanoes. Degassing of magmatic water typically involves bubble nucleation and growth, which drive magma ascent. Crystals suspended in magma may influence both nucleation and growth of bubbles.

Sensitivity of stratospheric ozone to the latitude, season, and halogen content of a contemporary explosive volcanic eruption

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

A stress-controlled mechanism for the intensity of very large magnitude explosive eruptions [PDF]

, 2011
Large magnitude explosive eruptions are the result of the rapid and large-scale transport of silicic magma stored in the Earth's crust, but the mechanics of erupting teratonnes of silicic magma remain poorly understood.

Responding to eruptive transitions during the 2020–2021 eruption of La Soufrière volcano, St. Vincent

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

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.

Pre-eruptive excess volatiles and their relationship to effusive and explosive eruption styles in semi-plugged volcanoes

Frontiers in Earth Science, 2022
Understanding the role of various factors influencing eruption style is challenging, but it can aid in adapting different hazard mitigations and crisis responses for explosive or effusive events.

Maars to calderas. End-members on a spectrum of explosive volcanic depressions [PDF]

, 2015
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 ...
