Bubble nucleation is at the heart of magma ascent and degassing. Nucleation kinetics
control how easily a magma exsolves its volatiles, and thereby its explosivity close to the …

ABSTRACT Ruapehu (150 km3 cone, 150 km3 ring-plain) and Tongariro (90 km3 cone, 60
km3 ring-plain) are iconic stratovolcanoes, formed since∼ 230 and∼ 350 ka, respectively …

Juvenile pyroclasts, especially in the ash size range, provide important information on
primary fragmentation processes, ie, initial explosive magma fragmentation, and on the state …

Ruapehu is an active~ 150 km 3 andesite-dacite composite volcano located at the southern
end of the Taupo Volcanic Zone, New Zealand. The growth of the present-day edifice has …

Arc magmas typically contain phenocrysts with complex zoning and diverse growth histories.
Microlites highlight the same level of intracrystalline variations but require nanoscale …

Diagnostic absorption features in hyperspectral data can be used to identify a specific
mineral or mineral associations. However, it is unknown how accurate hyperspectral …

We investigated the relationships between the size, shape, density and texture of thousands
of juvenile pyroclasts from the Plinian phase of the 1060 CE Glass Mountain eruption of …

Small-to-moderate explosive eruptions involve VEIs≤ 3, tephra volumes≤ 0.1 km3 and
often eject a significant amount of ash-sized pyroclastic material. This reduces the …

Volcanic reservoirs comprise reservoir spaces made up of pores and cracks, with secondary
solution pores and tectonic-induced cracks being the most dominant. Various volcanic …

Volcán de Colima, one of the Earth's most active and hazardous andesitic stratovolcanoes,
experienced its last major explosive eruption on July 2015 with two distinct events. The July …
