Evidences of Plug Pressurization Enhancing Magma Fragmentation During the September 2016 Basaltic Eruption at Piton de la Fournaise (La Réunion Island, France)

Geochemistry, Geophysics, Geosystems, 2020
In September 2016, Piton de la Fournaise volcano, well known for its effusive and Hawaiian fountaining activity, produced, at the end of the eruption, an unusual phase of pulsating ash and bomb emission. Integration of geophysical data, with textural and

Source Scaling of Shallow Volcano‐Tectonic Earthquakes at Piton de la Fournaise Volcano (La Réunion, France) Estimated From Codas of Seismograms

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Despite their importance for understanding faulting processes in volcanic environments, the source scaling of volcano‐tectonic earthquakes remains poorly constrained, mainly due to the difficulty of measuring their source parameters. We analyze source parameters such as seismic moments (M0 ${M}_{0}$) and corner frequencies (fc ${f}_{c}$) of ...

Magma Paths at Piton de la Fournaise Volcano: a synthesis of Hawaiian and Etnean rift zones

, 2014
International audienceOn ocean basaltic volcanoes, magma transfer to the surface occurs along sub-vertical ascent from the mantle lithosphere through the oceanic crust and the volcanic edifice, eventually followed by lateral propagation along rift zones.

Capturing Mayotte's deep magmatic plumbing system and its spatiotemporal evolution with volcano-tectonic seismicity

Volcanica, 2023
Since 2018 an unexpected number of earthquakes have been occurring offshore Mayotte, in the Mozambique Channel. They are linked to the eruption of the Fani Maoré submarine volcano.

Post‐Eruptive Deformation and Faulting Caused by Dike Channel Retraction, Material Drain‐Back and Contraction of the 2021 Tajogaite Craters (La Palma)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Young scoria cones fed by dike channels or conduits may undergo rapid and substantial post‐eruptive morphological modification; however, the structural controls and mechanisms governing topographic degradation remain poorly constrained. This knowledge gap limits our ability to reliably interpret topography, faults, deposits and the evolution ...

Integrating Olivine Diffusion Chronometry With Monitoring Data to Decipher the Magma Dynamics at the Submarine Fani Maoré Volcano

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Monitoring data are critical for understanding volcanic unrest and eruption, but they often lack the ability to constrain the pre‐eruptive magma processes. As such, an increasing number of studies couple monitoring data with petrological tools to obtain insights into the causes and durations of magmatic processes. The 2018–2020 eruption of the

A Machine Learning Approach for Volcanic Eruption Mass Estimation

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Estimation of total volcanic erupted mass—the primary metric of eruption magnitude—is typically performed post‐eruption relying on dense monitoring of ground‐based seismology, gravity and deformation instrumentation, and therefore exists for only ∼100 of ∼1280 volcanoes worldwide.

Controls on Magma Output From Stromboli's Plumbing System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Quantifying magma output over variable timescales is essential for understanding persistently active volcanoes. We analyze magma output at Stromboli (during 2000–2025) using satellite thermal data integrated with a comprehensive database of volcanic activity.

Volcanism at Piton de la Fournaise as an Analog for Chloris Mons, Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Identifying and investigating terrestrial analogs for Venus volcanic activity is necessary to prepare for the planned upcoming missions to Venus. We propose volcanism at Piton de la Fournaise, a frequently active oceanic shield volcano, as an analog to volcanism at Chloris Mons, Venus.
