D/H ratios and H2O contents record degassing and rehydration history of rhyolitic magma and pyroclasts
Volcanic eruptions of rhyolitic magma often show shifts from powerful (Vulcanian to Plinian)
explosive episodes to a more gentle effusion of viscous lava forming obsidian flows. Another …

An experimentally validated numerical model for bubble growth in magma
JP Coumans, EW Llewellin, FB Wadsworth… - Journal of Volcanology …, 2020 - Elsevier
Volcanic eruptions are driven by the growth of gas bubbles in magma. The timing and rate of
bubble growth are important because they determine whether enough gas pressure can …

Post-fragmentation vesiculation timescales in hydrous rhyolitic bombs from Chaitén volcano
Bubble nucleation and growth dynamics exert a primary control on the explosivity of volcanic
eruptions. Numerous theoretical and experimental studies aim to capture the complex …

Micro-porous pyroclasts reflecting multi-vent basaltic-andesite Plinian eruptions at Mt. Tongariro, New Zealand
Mt. Tongariro is a multi-vent volcanic complex in the central North Island of New Zealand,
constructed along the axis of an active graben. Its five largest-known explosive eruption …
