Storage and eruption of near-liquidus rhyolite magma at Cordón Caulle, Chile
The last three eruptions at the Cordón Caulle volcanic complex, Chile, have been strikingly
similar in that they have started with relatively short pre-eruptive warning and produced …

Havre 2012 pink pumice is evidence of a short-lived, deep-sea, magnetite nanolite-driven explosive eruption
The Havre 2012 deep-sea rhyolite eruption went unobserved and was initially recognised
from a massive pumice raft at the sea surface. Havre pumices are predominantly white or …

Shallow crystallization of eruptive magma inferred from volcanic ash microtextures: a case study of the 2018 eruption of Shinmoedake volcano, Japan
K Matsumoto, N Geshi - Bulletin of volcanology, 2021 - Springer
The occurrence of groundmass crystals reveals the shallow conduit process of magmas,
which affects the behavior of eruptions. Here, we analyzed groundmass microtextures of ash …
