Asymmetric magma plumbing system beneath Axial Seamount based on full waveform inversion of seismic data [PDF]

Nature Communications
The architecture of magma plumbing systems plays a fundamental role in volcano eruption and evolution. However, the precise configuration of crustal magma reservoirs and conduits responsible for supplying eruptions are difficult to explore across most ...

Translithospheric magma plumbing system fossilized in the Emeishan large igneous province

Communications Earth & Environment
Lighting 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.

Asynchronous transfer of magmas and mineralizing fluids in a plutonic-subvolcanic-volcanic plumbing system. [PDF]

Sci Rep
Abstract The geochronological-geochemical interplay between magma transfer and mineralizing fluid is studied at Campiglia igneous complex, Tuscany. Here, crustal and mantle-derived magmas were emplaced at plutonic, subvolcanic, and volcanic level (5.4 to 4.4 Ma), and were quickly exhumed, thus allowing U-Pb CA-ID-TIMS

Multiple mush generations provide insight into the longevity of open-conduit basaltic volcanoes [PDF]

Scientific Reports
Investigating the dynamics and timescales of magmatic processes in open-conduit basaltic volcanoes is crucial for improving our understanding of explosive eruptions and better assessing volcanic hazards.

Open-closed conduit transitions regulate the large magnitude explosive eruptions of Petrazza, PaleoStromboli I (Stromboli, Italy) [PDF]

Scientific Reports
A multi-disciplinary approach of volcano-stratigraphy, petrology and geochemistry has shed light on the pre-eruptive processes, the eruptive triggering, behaviour and the architecture of the magma plumbing system during the explosive cycle of Petrazza at

Magma flow localisation during dyke propagation produces complex magma transport pathways [PDF]

Nature Communications
Basaltic fissure eruptions, the most common type of eruption on Earth, are fed by dykes, which are magma-filled cracks that propagate through the crust.

Distinct patterns of volcano deformation for hot and cold magmatic systems [PDF]

Nature Communications
Volcano deformation can be detected over timescales from seconds to decades, offering valuable insights for magma dynamics. However, these signals are shaped by the long-term evolution of magmatic systems, a coupling that remains poorly understood.

Multiple magma recharges over prolonged period ultimately trigger eruptions at Vulcano, Aeolian Islands [PDF]

Scientific Reports
The compositional heterogeneity of clinopyroxene in products of the 1888-90 eruption at La Fossa of Vulcano has been used to constrain times of the plumbing system reactivation before the eruption.

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 ...
