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

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

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.

Deep Magma Transport Control on the Size and Evolution of Explosive Volcanic Eruptions
Frontiers in Earth Science, 2021 Explosive eruptions are the surface manifestation of dynamics that involve transfer of magma from the underground regions of magma accumulation. Evidence of the involvement of compositionally different magmas from different reservoirs is continuously ...

Temporal variations of magma composition, eruption style and rate at Fuji Volcano, Japan
Earth, Planets and Space, 2021 Mt. Fuji is an active basaltic volcano near the Tokyo metropolitan area; future eruptions could thus have serious nationwide impacts. To better understand recent volcanism at Fuji Volcano, we here clarify temporal variations of eruption rate and magma ...

Volcanological challenges to understanding explosive large-scale eruptions
Earth, Planets and Space, 2020 An explosive eruption, associated with the formation of a large ignimbrite sheet and collapsed caldera, is the most severe volcanic disaster on Earth.

Explosive Behavior of Intermediate Magmas: The Example of Cotopaxi Volcano (Ecuador)
Geochemistry, Geophysics, Geosystems, 2021 The variability in intensity and style shown by explosive volcanism has been traditionally explained by a complex interplay among melt composition and pre‐eruptive volatile content, which modulate magma ascent and conduit dynamics. However, magmas having

Survival of the Mýrdalsjökull ice cap through the Holocene thermal maximum: evidence from sulphur contents in Katla tephra layers (Iceland) from the last ∼8400 years [PDF]
, 2007 International audienceThe climate in Iceland was drier and warmer during the Holocene thermal maximum than it is today and it has been suggested that ice caps disappeared entirely. Katla, a volcano covered by the Mýrdalsjökull ice cap in southern Iceland,

Magma reservoir growth and ground deformation preceding the 79 CE Plinian eruption of Vesuvius
Communications Earth & Environment, 2023 The 79 CE eruption of Vesuvius is the first documented Plinian eruption, also famous for the archaeological ruins of Pompeii and Herculaneum. Although much is known regarding the eruption dynamics and magma reservoir, little is known about the reservoir ...

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