Volcanic eruptions shape Earth's surface and provide a window into deep Earth processes.
How the primary asthenospheric melts form, pond and ascend through the lithosphere is …

Deep-sea submarine eruptions are the least known type of volcanic activity, due to the
difficulty of detecting, monitoring, and sampling them. Following an intense seismic crisis in …

Geological CO 2 degassing is a fundamental Earth process but still quite poorly understood,
since a thorough quantification with conventional measurement techniques is challenging …

Nanoscale liquid immiscibility is observed in the 2018–2021 Fani Maoré submarine lavas
(Comoros archipelago). Heat transfer calculations, Raman spectroscopy, scanning and …

Juvenile pyroclasts, especially in the ash size range, provide important information on
primary fragmentation processes, ie, initial explosive magma fragmentation, and on the state …

L'éruption au large de Mayotte a été intensément surveillée en appliquant des méthodes
similaires aux éruptions sub-aériennes. Une étude pétrologique et géochimique des …

Due to their generally low eruptive melt viscosities and concomitant high diffusivities of
volatiles, basaltic magmas degas relatively efficiently. This relative efficiency, combined with …

The partitioning behavior of Fe and Mg between olivine and basalt melt is of key importance
to the study of terrestrial and extraterrestrial basalts. Olivine-melt partitioning studies …

Magma propagation is an unsteady process controlled by magma‐crust interaction. To
provide information on its dynamics, we invert complementary ground deformation data …

Small-volume proximal-summit eruptions, sometimes with only little precursors, are common
at Piton de la Fournaise (La Reunion Island, France). Their eruptive style ranges from …
