New insight into explosive volcanic eruptions: Connecting crystal-scale chemical changes with conduit-scale dynamics
Explosive volcanic eruptions may be triggered by processes in the conduit, including PT
variations, volatile loss, and crystal growth. These unobserved processes may be inferred …

Integrating field, textural, and geochemical monitoring to track eruption triggers and dynamics: a case study from Piton de la Fournaise
The 2014 eruption at Piton de la Fournaise (PdF), La Réunion, which occurred after 41
months of quiescence, began with surprisingly little precursory activity and was one of the …

Fluid fluxing and accumulation drive decadal and short-lived explosive basaltic andesite eruptions preceded by limited volcanic unrest
Some volcanoes are known for repeatedly producing explosive but short-lived eruptions (<
half a day) every decade or so. These eruptions are often preceded by limited unrest signals …

A data driven approach to mineral chemistry unveils magmatic processes associated with long-lasting, low-intensity volcanic activity
The most frequent volcanic eruptions are of low-intensity and small magnitude. They
produce abundant ash-sized (< 2 mm) clasts, which are too small to establish quantitative …

Geochemical variations in late-stage growth of volcanic phenocrysts revealed by SIMS depth-profiling
In the petrologic and geochemical study of volcanic rocks, microlites have become an
important tool with which to determine magma decompression rate and ascent path prior to …

Volatile dilution during magma injections and implications for volcano explosivity
Magma reservoirs underneath volcanoes grow through episodic emplacement of magma
batches. These pulsed magma injections can substantially alter the physical state of the …

Storage and eruption of silicic magma across the transition from dominantly effusive to caldera-forming states at an arc volcano (Santorini, Greece)
Caldera-forming eruptions at Santorini discharge large volumes of silicic magma from upper
crustal reservoirs. Sequences of smaller eruptions preceding the main explosive eruptions …

Magmatic processes at La Soufrière de Guadeloupe: Insights from crystal studies and diffusion timescales for eruption onset
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 …

Volcanic crystals as time capsules of eruption history
Crystals formed prior to a volcanic event can provide evidence of processes leading to and
timing of eruptions. Clinopyroxene is common in basaltic to intermediate volcanoes …
