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 ...

Crust and Uppermost Mantle Magma Plumbing System Beneath Changbaishan Intraplate Volcano, China/North Korea, Revealed by Ambient Noise Adjoint Tomography

Geophysical Research Letters, 2022
Changbaishan volcano (CBV), straddling the border between China and North Korea, is one of the most intriguing and explosive volcanoes on Earth owing to its voluminous Holocene eruptions and unusual magma composition within a continental intraplate ...

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.

Anatomy of the magmatic plumbing system of Los Humeros Caldera (Mexico): implications for geothermal systems [PDF]

Solid Earth, 2020
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 geometry, depth, and temperature of the heat sources for geothermal exploration. The

Two Distinct Magma Storage Regions at Ambrym Volcano Detected by Satellite Geodesy

Geophysical Research Letters, 2023
The flux of eruptible magma into a magmatic plumbing system influences eruption size and timing. If magma transfer is possible between two hydraulically‐connected magma lenses, system destabilization can tap a larger magma volume than stored in any one ...
