Geochemistry, Geophysics, Geosystems, 2023 Alaska contains over 130 volcanoes and volcanic fields that have been active within the last 2 million years. Of these, roughly 90 have erupted during the Holocene, with many characterized by at least one large explosive eruption.

Charge structure in volcanic plumes: a comparison of plume properties predicted by an integral plume model to observations of volcanic lightning during the 2010 eruption of Eyjafjallajökull, Iceland [PDF]
, 2014 Cancer is a heterogeneous disease with different combinations of genetic alterations driving its development in different individuals. We introduce CoMEt, an algorithm to identify combinations of alterations that exhibit a pattern of mutual exclusivity ...

Sulfur as a binding agent of aggregates in explosive eruptions [PDF]
Bulletin of Volcanology, 2014 Understanding the mechanisms that govern ash aggregation is of critical importance in volcanology. Aggregation reduces the residence time of ash (≤2 mm) in the atmosphere strongly, by enhancing the sedimentation of finer-grained material generated during explosive eruptions.

Radiative and climate impacts of a large volcanic eruption during stratospheric sulfur geoengineering [PDF]
Atmospheric Chemistry and Physics, 2016 Both explosive volcanic eruptions, which emit sulfur dioxide into the stratosphere, and stratospheric geoengineering via sulfur injections can potentially cool the climate by increasing the amount of scattering particles in the atmosphere. Here we employ

Pyroclasts of the first phases of the explosive-effusive PCCVC volcanic eruption: physicochemical analysis [PDF]
, 2015 The morphology, texture, grain size and other physicochemical characteristics of pyroclastic material from the first phases of the Puyehue-Cordon Caulle volcanic complex (PCCVC) eruption, (Southern Andes, Chile), can be associated to the model recently ...

Laboratory studies on electrical effects during volcanic eruptions
Annals of Geophysics, 1999 This laboratory study reports on electrical phenomena during the explosive eruption of a basaltoid silicate melt. Contact electricity is produced in the phase of thermo-hydraulic fracturing of magma during the explosive interaction with water.

Evidence of mid- to late-Holocene explosive rhyolitic eruptions from Chaitén Volcano, Chile
Andean Geology, 2013 The 2008 eruption of Chaitén Volcano was widely cited as the first activity at the volcano for over 9000 years. However, we have identified evidence from proximal pyroclastic deposits for three additional explosive eruptions of Chaitén within the past ...

Understanding the plume dynamics of explosive super-eruptions [PDF]
Nature Communications, 2018 AbstractExplosive super-eruptions can erupt up to thousands of km3 of magma with extremely high mass flow rates (MFR). The plume dynamics of these super-eruptions are still poorly understood. To understand the processes operating in these plumes we used a fluid-dynamical model to simulate what happens at a range of MFR, from values generating intense ...

Cryospheric Impacts on Volcano-Magmatic Systems
Frontiers in Earth Science, 2022 In contrast to water and air, ice is the most dynamic enveloping medium and unique environment for volcanic eruptions. While all three environments influence volcanic activity and eruption products, the cryospheric eruption environment is unique because:

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 ...
