Translithospheric magma plumbing system fossilized in the Emeishan large igneous province
Communications Earth & EnvironmentLighting up the magma plumbing system beneath a large igneous province (LIP) is challenging because the complex magma migration paths are often covered by flood basalts and sediments.

Magma plumbing system and seismicity of an active mid-ocean ridge volcano. [PDF]
Sci Rep, 2017 AbstractAt mid-ocean ridges volcanism generally decreases with spreading rate but surprisingly massive volcanic centres occur at the slowest spreading ridges. These volcanoes can host unexpectedly strong earthquakes and vigorous, explosive submarine eruptions.

Evolution of the magma plumbing system of Miyakejima volcano with periodic recharge of basaltic magmas [PDF]
Earth, Planets and Space, 2022 AbstractDefining the variations in petrological characteristics of erupted magmas within a high-resolution chronostratigraphy provides a necessary framework for monitoring the long-term activity and eruption potential of an active volcano. Here, we investigate the evolution of the magmatic system of Miyakejima volcano, Japan, between the last two ...

Magma Plumbing Systems: A Geophysical Perspective [PDF]
Journal of Petrology, 2018 Over the last few decades, significant advances in using geophysical techniques to image the structure of magma plumbing systems have enabled the identification of zones of melt accumulation, crystal mush development, and magma migration. Combining advanced geophysical observations with petrological and geochemical data has arguably revolutionised our ...

Episodic transport of discrete magma batches beneath Aso volcano
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

Consequences of a crystal mush-dominated magma plumbing system: a mid-ocean ridge perspective. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 Crystal mush is rapidly emerging as a new paradigm for the evolution of igneous systems. Mid-ocean ridges provide a unique opportunity to study mush processes: geophysical data indicate that, even at the most magmatically robust fast-spreading ridges, the magma plumbing system typically comprises crystal mush.

Imaging a magma plumbing system from MASH zone to magma reservoir [PDF]
Earth and Planetary Science Letters, 2017 The Puna Plateau of the Central Andes is a well-suited location to investigate the processes associated with the tectono-magmatic development of a Cordilleran system. These processes include long-lived subduction (including shallow and steep phases), substantial crustal thickening, the emplacement of large volumes of igneous rocks, and probably ...

Geophysical Research Letters, 2023 Volcanic seismicity provides essential insights into the behavior of an active volcano across multiple time scales. However, to understand how magma moves as the eruption cycle develops, better knowledge of the geometry and physical properties of the ...

Scientific Reports, 2021 The Tatun Volcanic Group (TVG) is proximal to the metropolis of Taipei City (population of ca. 7 million) and has long been a major concern due to the potential risks from volcanic activity to the population and critical infrastructure. While the TVG has
