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 …

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

In the broadest sense, volcanic eruptions are either effusive or explosive. During explosive
eruptions magma fragments and eruption intensity is ultimately related to the fragmentation …

The 1995–present eruption of Soufrière Hills Volcano on Montserrat has produced over a
cubic kilometre of andesitic magma, creating a series of lava domes that were successively …

Basaltic pyroclastic volcanism takes place over a range of scales and styles, from weak
discrete Strombolian explosions (∼ 102–103kgs− 1) to Plinian eruptions of moderate …

Understanding the anatomy of magma plumbing systems of active volcanoes is essential not
only for unraveling magma dynamics and eruptive behaviors but also to define the …

Decompression experiments were performed to study the kinetics of plagioclase
crystallization during ascent of hydrous rhyodacite magma. These experiments differ from …

The eruption style of silicic magmas is affected by the loss of gas (outgassing) during ascent.
We investigate outgassing using a numerical model for one-dimensional, two-phase, steady …

Soufrière Hills Volcano had two periods of repetitive Vulcanian activity in 1997. Each
explosion discharged the contents of the upper 0.5–2km of the conduit as pyroclastic flows …

Decompression experiments have been conducted to simulate syn-eruptive crystallization in
volcanic conduits, to infer magma ascent rates and conditions during dome-forming and …
