Bubble formation in magma
Volcanic eruptions are driven by bubbles that form when volatile species exsolve from
magma. The conditions under which bubbles form depend mainly on magma composition …

Variety of the drift pumice clasts from the 2021 Fukutoku‐Oka‐no‐Ba eruption, Japan
Pumice rafts that arrived at the Nansei Islands, Japan, provided a unique opportunity to
investigate the Fukutoku‐Oka‐no‐Ba (FOB) eruption of August 2021. Despite drifting for 2 …

Reconciling bubble nucleation in explosive eruptions with geospeedometers
S Hajimirza, HM Gonnermann, JE Gardner - Nature communications, 2021 - nature.com
Magma from Plinian volcanic eruptions contains an extraordinarily large numbers of
bubbles. Nucleation of those bubbles occurs because pressure decreases as magma rises …

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 …
