Explosive Activity on Kīlauea's Lower East Rift Zone Fueled by a Volatile‐Rich, Dacitic Melt

Geochemistry, Geophysics, Geosystems, 2022
Magmas with matrix glass compositions ranging from basalt to dacite erupted from a series of 24 fissures in the first 2 weeks of the 2018 Lower East Rift Zone (LERZ) eruption of Kīlauea Volcano.

Temporal variability of explosive activity at Tajogaite volcano, Cumbre Vieja (Canary Islands), 2021 eruption from ground-based infrared photography and videography

Frontiers in Earth Science, 2023
The 2021 eruption at Tajogaite (Cumbre Vieja) volcano (La Palma, Spain) was characterized by Strombolian eruptions, Hawaiian fountaining, white gas-dominated and grey ash-rich plumes, and lava effusion from multiple vents.

An analytical model for gas overpressure in slug-driven explosions:insights into Strombolian volcanic eruptions [PDF]

, 2012
Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.

Explosive Volcanism in a tuff-dominated Intraplate Setting, Sarmiento Formation (Middle Eocene- lower Miocene), Patagonia Argentina

Latin American Journal of Sedimentology and Basin Analysis, 2021
The Sarmiento Formation (middle Eocene to early Miocene) represents the distal record of the activity of the Andean volcanic arc in central Patagonia, mainly dominated by accumulation and reworking of fine ash in a low-gradient continental setting ...

Magmatic Processes at La Soufrière de Guadeloupe: Insights From Crystal Studies and Diffusion Timescales for Eruption Onset

Frontiers in Earth Science, 2021
Signals of volcanic unrest do not usually provide insights into the timing, size and style of future eruptions, but detailed analysis of past eruptions may uncover patterns that can be used to understand future eruptive behavior.

Stronger or longer: Discriminating between Hawaiian and Strombolian eruption styles [PDF]

, 2016
The weakest explosive volcanic eruptions globally, Strombolian explosions and Hawaiian fountaining, are also the most common. Yet, despite over a hundred years of observations, no classifications have offered a convincing, quantitative way of demarcating

Recycled ejecta modulating Strombolian explosions [PDF]

, 2016
Two main end-members of eruptive regimes are identified from analyses of high-speed videos collected at Stromboli volcano (Italy), based on vent conditions: one where the vent is completely clogged by debris, and a second where the vent is open, without ...

Gas flow dynamics in the conduit of Strombolian explosions inferred from seismo-acoustic observations at Aso volcano, Japan

Earth, Planets and Space, 2019
Strombolian explosions are one of the most studied eruptive styles and are characterized by intermittent explosions. The mechanism of a Strombolian explosion is modeled as a large gas pocket (slug) migrating through the magma conduit and then bursting at

Volcanic ballistic projectile deposition from a continuously erupting volcano: Yasur Volcano, Vanuatu

Volcanica, 2020
Volcanic ballistics are the main hazard to life and infrastructure from Strombolian eruptions, which are a tourist drawcard, exposing people to this hazard.

A 36,000-Year-Old Volcanic Eruption Depicted in the Chauvet-Pont d'Arc Cave (Ardèche, France)? [PDF]

PLoS ONE, 2016
Among the paintings and engravings found in the Chauvet-Pont d'Arc cave (Ardèche, France), several peculiar spray-shape signs have been previously described in the Megaloceros Gallery.
