Pyroclasts of the first phases of the explosive-effusive PCCVC volcanic eruption: physicochemical analysis [PDF]

open access: yes, 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 ...

Influence of hydrothermal recharge on the evolution of eruption styles and hazards during the 2018–2019 activity at Kuchinoerabujima Volcano, Japan

open access: yesEarth, Planets and Space, 2022
The activity of the 2018–2019 eruption of Kuchinoerabujima Volcano in Japan changed from continuous ejection of ash-laden plumes between October 21 and the middle of December, to intermittent explosive activity accompanied by several pyroclastic density ...

Cryospheric Impacts on Volcano-Magmatic Systems

open access: yesFrontiers 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:

SO2 emissions from basaltic eruptions, and the excess sulfur issue [PDF]

open access: yes, 2004
Volcanic SO2 can affect the Earth's environment. Where no direct measurements of SO2 in the atmosphere are available, a petrologic method of assessing sulfur release from the magma must be used.

Electric Discharge in Erupting Mud

open access: yesGeophysical Research Letters, 2022
Self‐ignition during the explosive eruption of mud volcanoes can create flames that in some cases reach heights that exceed hundreds of meters. To study the controls on electrical discharge in natural mud, we performed laboratory experiments using a ...

Explosive and Eruptive Stars [PDF]

open access: yesSymposium - International Astronomical Union, 1974
A summary of the main results and problems concerning explosive and eruptive stars is given. The way in which the observations are related to the internal structure problems is briefly explained. Suggestions for further work are made: (1) dynamo theory, supersonic turbulence, stability of the envelope of T Tau stars; (2) rate of exchange of matter in ...

Activation of the Sarychev Peak volcano in 2020–2021 (Matua Isl., the Central Kuril Islands) [PDF]

open access: yesГеосистемы переходных зон, 2021
This publication, based on remote sensing data, examines the features of the effusive eruption of the Sarychev Peak volcano (Matua Isl., the Central Kuril Islands), which took place from December 2020 till February 2021.

Magma volume, volatile emissions, and stratospheric aerosols from the 1815 eruption of Tambora [PDF]

open access: yes, 2004
We suggest that the Tambora 1815 eruption was smaller than previously thought, yielding 30–33 km3 of magma. Valuable insight into the eruption is gained by comparing it to the much smaller 1991 Pinatubo event, which had a similar eruption style and rate.

Analysis of the Alaska Volcano Observatory's Response Time to Volcanic Explosions-1989 to 2016

open access: yesFrontiers in Earth Science, 2018
A major goal of volcano monitoring is the rapid identification of volcanic explosions and subsequent warning of associated hazards. Between 1988 and 2016 the Alaska Volcano Observatory (AVO) responded to at least 54 separate volcanic eruptions.

European climate response to tropical volcanic eruptions over the last half millennium [PDF]

open access: yes, 2007
We analyse the winter and summer climatic signal following 15 major tropical volcanic eruptions over the last half millennium based on multi-proxy reconstructions for Europe. During the first and second post-eruption years we find significant continental
