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:

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 ...

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.

Deep Sea Explosive Eruptions may be not so Different from Subaerial Eruptions [PDF]

open access: yesGoldschmidt Abstracts, 2020
AbstractThe dynamics of deep sea explosive eruptions, the dispersion of the pyroclasts, and how submarine eruptions differ from the subaerial ones are still poorly known due to the limited access to sea environments. Here, we analyze two ash layers representative of the proximal and distal deposits of two submarine eruptions from a 500 to 800 m deep ...

Modeling the distribution of the volcanic aerosol cloud from the 1783–1784 Laki eruption [PDF]

open access: yes, 2006
We conducted simulations of the atmospheric transformation and transport of the emissions of the 1783–1784 Laki basaltic flood lava eruption (64.10°N, 17.15°W) using the NASA Goddard Institute for Space Studies modelE climate model coupled to a sulfur ...

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.

An analytical model for gas overpressure in slug-driven explosions : insights into Strombolian volcanic eruptions [PDF]

open access: yes, 2012
Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.

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

Havre 2012 pink pumice is evidence of a short-lived, deep-sea, magnetite nanolite-driven explosive eruption

open access: yesCommunications 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.
