Petrology of the 2020–21 effusive to explosive eruption of La Soufrière Volcano, St Vincent: insights into plumbing system architecture and magma assembly …
Abstract The 2020–21 eruption of La Soufrière, St Vincent began with extrusion of a viscous
lava dome, which was destroyed upon transition to a major explosive phase. Here we …

Reckoning with the rocky relationship between eruption size and climate response: toward a volcano-climate index
Volcanic eruptions impact climate, subtly and profoundly. The size of an eruption is only
loosely correlated with the severity of its climate effects, which can include changes in …

Decadal transition from quiescence to supereruption: petrologic investigation of the Lava Creek Tuff, Yellowstone Caldera, WY
The magmatic processes responsible for triggering nature's most destructive eruptions and
their associated timescales remain poorly understood. Yellowstone Caldera is a large silicic …

The magma plumbing system of Merapi: The petrological perspective
Abstract Merapi volcano in Central Java is one of the most active volcanoes in the Sunda arc
and poses a continuous threat to the local population. Basaltic-andesites from Merapi carry …

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 connection between magma chamber processes and eruptive styles revealed at Nisyros-Yali volcano (Greece)
Arc volcanoes generally emit water-rich, high-viscosity silicic magmas, which are prone to
erupt explosively. However, effusive behavior is a common occurrence despite the high-H 2 …

[HTML][HTML] Magmatic volatile content and the overpressure 'sweet spot': Implications for volcanic eruption triggering and style
Volatile exsolution is widely considered to be capable of generating magmatic overpressure
and triggering volcanic eruptions. Despite its role as an eruption trigger, exsolution-driven …
