Magma flow localisation during dyke propagation produces complex magma transport pathways [PDF]
Nature CommunicationsBasaltic fissure eruptions, the most common type of eruption on Earth, are fed by dykes, which are magma-filled cracks that propagate through the crust.

Episodic transport of discrete magma batches beneath Aso volcano [PDF]
Nature Communications, 2021 Repetitive shallow resonances provide a pathway to unravelling episodic magma transport deep in the magma plumbing system. Episodic deformation of ~1 nanoradian over ~100 s beneath Aso volcano potentially provides a link between long-term volcanic output

Transport of melt, pressure and heat through a magma mush
Frontiers in Earth Science, 2023 Prior to intrusion, magma migrates through the crustal plumbing system that likely contains layers or columns of crystal mush. To better understand the behavior of the crustal magmatic system during magmatic unrest, it is important to examine the process

Distribution and Transport of Thermal Energy within Magma–Hydrothermal Systems
Geosciences, 2020 Proximity to magma bodies is generally acknowledged as providing the energy source for hot hydrothermal reservoirs. Hence, it is appropriate to think of a “magma–hydrothermal system” as an entity, rather than as separate systems.

Combining InSAR and GNSS to Track Magma Transport at Basaltic Volcanoes [PDF]
Remote Sensing, 2019 The added value of combining InSAR and GNSS data, characterized by good spatial coverage and high temporal resolution, respectively, is evaluated based on a specific event: the propagation of the magma intrusion leading to the 26 May 2016 eruption at ...

Modeling the Intermittent Lava Lake Drops Occurring Between 2015 and 2021 at Nyiragongo Volcano
Geophysical Research Letters, 2023 Between 2015 and 2021, Nyiragongo's lava lake level experienced a linear increase punctuated by fast intermittent drops. These drops occurred synchronously to seismic swarm at approximately 15 km below the surface and extending laterally NE from the ...

Insights into magma ocean dynamics from the transport properties of basaltic melt
Nature Communications, 2022 The viscosity of magma plays a crucial role in the dynamics of planet Earth. In this study, the authors show how transport properties of basaltic melt can give us insights into magma ocean dynamics.

Transport and eruption of mantle xenoliths creates a lagging problem
Communications Earth & Environment, 2023 Mantle-derived xenoliths entrained by low viscosity magmas indicate transport through great thicknesses of orogenic (≲50-80 km) and cratonic ( $$\lesssim$$ ≲ 20 km) mantle lithosphere.

Tectonic Controls on Global Variations of Large-Magnitude Explosive Eruptions in Volcanic Arcs
Frontiers in Earth Science, 2020 Linking tectonic setting to eruptive activity in volcanic arcs provides a framework to understand processes that control the production, accumulation and eruption of magma on Earth.
