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 …

High‐resolution InSAR reveals localized pre‐eruptive deformation inside the crater of Agung Volcano, Indonesia
During a volcanic crisis, high‐rate, localized deformation can indicate magma close to the
surface, with important implications for eruption forecasting. However, only a few such …

[HTML][HTML] A reappraisal of explosive–effusive silicic eruption dynamics: syn-eruptive assembly of lava from the products of cryptic fragmentation
Silicic volcanic eruptions range in style from gently effusive to highly explosive, and may
switch style unpredictably during a single eruption. Direct observations of subaerial rhyolitic …

Trapdoor fault activation: A step toward caldera collapse at Sierra Negra, Galápagos, Ecuador
Abstract The 2018 Sierra Negra eruption resulted in meter‐scale subsidence due to basaltic
magma extraction from a deflating reservoir. The eruption was also characterized by dike …

[HTML][HTML] Outgassing through magmatic fractures enables effusive eruption of silicic magma
Several mechanisms have been proposed to allow highly viscous silicic magma to outgas
efficiently enough to erupt effusively. There is increasing evidence that challenges the …

Magma buoyancy drives rhyolitic eruptions: A tale from the VEI 5 2008-2009 Chaitén eruption (Chile) from seismological and geodetic data
Magma buoyancy is a mechanism usually neglected with respect to magma overpressure in
eruption models constrained with geophysical data. In this study we provide evidence for a …

Anatomy of a high-silica eruption as observed by a local seismic network: the June 2011 Puyehue–Cordón Caulle event (southern Andes, Chile)
D Basualto, A Tassara, J Lazo-Gil, L Franco-Marin… - Solid Earth, 2023 - se.copernicus.org
High-silica explosive eruptions are one of the most dangerous natural phenomena, yet it is
unclear which processes are involved in this infrequent kind of event. We present the first …
