Havre 2012 pink pumice is evidence of a short-lived, deep-sea, magnetite nanolite-driven explosive eruption [PDF]
Communications Earth & Environment, 2022 Pink and white raft pumice from the 2012 Havre deep-sea eruption experienced prolonged high-temperature atmospheric oxidation of magnetite to hematite which suggests a short but powerful explosive phase, according to microanalytical investigation.

Rapid laccolith intrusion driven by explosive volcanic eruption [PDF]
Nature Communications, 2016 Magmatic intrusions are thought to precede volcanic eruptions. However, Castro et al. present evidence that a laccolith was emplaced during the 2011 rhyolitic eruption of Cordón Caulle showing that eruptions may force the intrusion of magma into the ...

Melt stripping and agglutination of pyroclasts during the explosive eruption of low viscosity magmas. [PDF]
Nat Commun, 2022 Volcanism on Earth and on other planets and satellites is dominated by the eruption of low viscosity magmas. During explosive eruption, high melt temperatures and the inherent low viscosity of the fluidal pyroclasts allow for substantial post ...

Anatomy of the Bezymianny volcano merely before an explosive eruption on 20.12.2017. [PDF]
Sci Rep, 2021 Strong explosive eruptions of volcanoes throw out mixtures of gases and ash from high-pressure underground reservoirs. Investigating these subsurface reservoirs may help to forecast and characterize an eruption.

Explosive eruption, flank collapse and megatsunami at Tenerife ca. 170 ka. [PDF]
Nat Commun, 2017 Giant mass failures of oceanic shield volcanoes that generate tsunamis potentially represent a high-magnitude but low-frequency hazard, and it is actually difficult to infer the mechanisms and dynamics controlling them.

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.

Controls on explosive-effusive volcanic eruption styles
Nature Communications, 2018 Eruptive styles at a single volcano may transition from explosive to effusive behaviour (or vice versa) at any given time. This review examines the underlying controls on eruptive styles such as magma viscosity, degassing and conduit geometry at ...

Characterisation of the Quaternary eruption record: analysis of the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database [PDF]
Journal of Applied Volcanology, 2014 The Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database contains data on 1,883 Quaternary eruption records of magnitude (M) 4 and above and is publically accessible online via the British Geological Survey. Spatial and temporal analysis of the
