Relations between magma ascent rate and explosivity

, 2023
A ce jour, alors que l'occurrence d'une éruption majeure n'est pas clairement déterminée, une seconde question se pose concernant la puissance de celle-ci. La gestion de l'évacuation des populations ou encore l'établissement de cartes de risques volcaniques dépendent directement de ce paramètre.

Large (∼80 km) Shield Volcanoes on the Moon Possibly Fed by Shallow Magma Reservoirs

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Large shield volcanoes are among the most prominent volcanic structures on terrestrial bodies. The Moon, while volcanically very active in the past and hosting various volcanic features, seems to lack such large shield volcanoes. Here, we report the identification of two lunar volcanic domes (Prinz‐Harbinger and Theophilus) with diameters ...

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

Very‐Long‐Period Seismic Signals During Lateral Dike Propagation at Piton de La Fournaise Volcano

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We report a previously undocumented sequence of very long period (VLP) signals preceding the September 2022 eruption at Piton de la Fournaise. These events occurred during lateral magma propagation and exhibit quasi‐periodic sawtooth‐shaped displacement transients.
