Transitions between explosive and effusive phases during the cataclysmic 2010 eruption of Merapi volcano, Java, Indonesia

open access: yesBulletin of Volcanology, 2016
Transitions between explosive and effusive activity are commonly observed during dome-forming eruptions and may be linked to factors such as magma influx, ascent rate and degassing.

The January 2022 eruption of Hunga Tonga-Hunga Ha’apai volcano reached the mesosphere

open access: yesScience, 2022
Explosive volcanic eruptions can loft ash, gases, and water into the stratosphere, which affects both human activities and the climate. Using geostationary satellite images of the 15 January 2022 eruption of the Hunga Tonga-Hunga Ha’apai volcano, we find

CO2-crystal wettability in potassic magmas. Implications for eruptive dynamics in light of experimental evidence for heterogeneous nucleation. [PDF]

open access: yes, 2017
The volatile content in magmas is fundamental for the triggering and style of volcanic eruptions. Carbon dioxide, the second most abundant volatile component in magmas after H2O, is the first to reach saturation upon ascent and depressurization.

Aspects of Radical Gay Liberation Theory in West Germany's Tuntenstreit, 1973–1975

open access: yesGender &History, EarlyView.
ABSTRACT This article examines in depth the theoretical positions of the Tuntenstreit – a major theoretical dispute within the radical West German gay liberation movement in the 1970s. By working through archival material as well as the dispute's fundamental texts, it renders visible its often‐neglected underlying theoretical motifs and, consequently ...

Can riots represent? A democratic theory

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Political theory has been perennially concerned with interrogating, identifying, and clarifying the political functions of riots. Yet, political theorists have mostly fallen short of explaining the relationship between riots and democracy, although this is central to the democratic theory of contestation and crucial for evaluating the ...

Characterizing thermal transitions of the 2018 Shinmoe-dake eruption in Japan using Himawari-8 high-frequency infrared imagery and seismic data

open access: yesEarth, Planets and Space
Discrete explosive eruptions, including vulcanian eruptions, occur at various stages during the effusion of viscous lava. However, the differences in occurrence time and mechanisms are not yet well understood or categorized.

Why Deep-Water Eruptions Are So Different From Subaerial Eruptions

open access: yesFrontiers in Earth Science, 2018
Magmas erupted in deep-water environments (>500 m) are subject to physical constraints very different to those for subaerial eruptions, including hydrostatic pressure, bulk modulus, thermal conductivity, heat capacity and the density of water mass ...

Dissolved Gas and Metal Composition of Hydrothermal Plumes From a 2008 Submarine Eruption on the Northeast Lau Spreading Center

open access: yesFrontiers in Marine Science, 2020
Extrusion of lava onto the seafloor transports heat and mass from the lithosphere to the hydrosphere and the biosphere. During this process, large amounts of dissolved gases can be released into the ocean as hydrothermal plumes and serve as nutrients for
