Spatial and temporal quantification of subaerial volcanism from 1980 to 2019: solid products, masses, and average eruptive rates
Volcanism is one of the main mechanisms transferring mass and energy between the
interior of the Earth and the Earth's surface. However, the global mass flux of lava, volcanic …

Evolution and dynamics of the open-vent eruption at Arenal volcano (Costa Rica, 1968–2010): what we learned and perspectives
On 29 July 1968, there was a violent reactivation of Arenal volcano. The resulting westward-
directed lateral blast eruption left two villages destroyed and 78 people dead. The activity …

Emplacement dynamics of a crystal-rich, highly viscous trachytic flow of the Sancy stratovolcano, France
Emplacement dynamics of highly viscous, silicic lava flows remain poorly constrained due to
a lack of consideration of crystal-rich cases. Emplacement models mostly apply to glassy or …
