Explosive volcanic eruptions constitute a major class of natural hazard with potentially
profound economic and societal consequences. Although such eruptions cannot be …

Studies of magmatic systems have long used the textures of erupted samples to infer
processes that control the location and duration of magma storage and drive volcanic …

Experiments were conducted to study the temporal evolution of feldspar crystallization
kinetics during isothermal decompression. Pinatubo dacite was held at 780° C, 220 MPa …

Despite the abundance of SO2 (g) in magmatic gases, precursory increases in magmatic
SO2 (g) are not always observed prior to volcanic eruption, probably because many …

Dacite tephras produced by the 1991 pre-climactic eruptive sequence at Mt. Pinatubo
display extreme heterogeneity in vesicularity, ranging in clast density from 700 to 2580 kg m …

The prevalence of andesitic and dacitic volcanic eruptions over the past 20 years has led to
a new appreciation of processes typical of magmas of intermediate composition. Extensive …

Eruption of the Soufrière Hills Volcano on Montserrat allowed the detailed documentation of
a Pélean dome-forming eruption. Dome growth between November 1995 and March 1998 …

Volcano-tectonic (VT) seismicity is commonly recorded prior to and during eruptions. VT
seismicity may reflect stresses induced by dike propagation, as indicated by propagating …

Large‐scale volcanic eruptions produce fine ash (< 200 μm) which has a long atmospheric
residence time (1 hour or more) and can be transported great distances from the volcanic …

Volatiles provide the primary driving force for volcanic eruptions, thus understanding magma
degassing is fundamental to understanding volcanic activity in volatile-rich arc …
