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.

Controls on explosive-effusive volcanic eruption styles [PDF]
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 ...

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.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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

Practising an explosive eruption in Iceland: outcomes from a European exercise [PDF]
Journal of Applied Volcanology, 2020 A 3 day exercise simulating unrest and a large explosive eruption at Katla volcano, Iceland, was conducted in January 2016. A large volume of simulated data based on a complex, but realistic eruption scenario was compiled in advance and then transmitted ...

Highly explosive basaltic eruptions driven by CO2 exsolution [PDF]
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 ...
