One of the biggest challenges in volcanic hazard assessment is to understand how and why
eruptive style changes within the same eruptive period or even from one eruption to the next …

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 …

The mechanisms of hazardous silicic eruptions are controlled by complex, poorly-
understood conduit processes. Observations of recent Chilean rhyolite eruptions have …

Explosive silicic volcanism is driven by gas overpressure in systems that are inefficient at
outgassing. The zone at the margin of a volcanic conduit—thought to play an important role …

A close relationship between Ni–Cu–(PGE) sulfide deposits and magmatic conduit systems
has been widely accepted, but our present understanding still rests on empirical inductions …

Gas‐and‐ash explosions at the Santiaguito dome complex, Guatemala, commonly occur
through arcuate fractures, following a 5‐to 6‐min period of inflation observed in long‐period …

Paroxysmal activity represents an end-member in the common range of activity at mafic arc
volcanoes, characterised by rapid transitions across the effusive-explosive interface and …

Explosive volcanic eruptions can produce vast amounts of volcanic ash made up mainly of
fragments of magmatic glass, country rock and minerals< 2 mm in size. Ash particles forming …

Signals of volcanic unrest do not usually provide insights into the timing, size and style of
future eruptions, but detailed analysis of past eruptions may uncover patterns that can be …

Abstract Rabaul in Papua-New-Guinea is an extremely active andesitic caldera complex that
displays a large spectrum of eruption styles. Since 1878, four sub-plinian (VEI-4) and ten VEI …
