Multiparameter quantification of gas release during weak Strombolian eruptions at Pacaya Volcano, Guatemala [PDF]

open access: bronzeGeophysical Research Letters, 2010
Activity at Pacaya volcano, Guatemala is characterized by persistent degassing, coupled at times with lava effusion and/or coincident Strombolian‐style explosions. We used 0.25 Hz sample rate sulfur dioxide emission data from a UV camera and coincident infrasound recordings to investigate the link between varied emission rates and infrasound events ...

Viscous plugging can enhance and modulate explosivity of strombolian eruptions

open access: goldEarth and Planetary Science Letters, 2015
Strombolian activity is common in low-viscosity volcanism. It is characterised by quasi-periodic, short-lived explosions, which, whilst typically weak, may vary greatly in magnitude. The current paradigm for a strombolian volcanic eruption postulates a large gas bubble (slug) bursting explosively after ascending a conduit filled with low-viscosity ...

Submarine strombolian eruptions on the Gorda mid-ocean ridge

open access: closed, 2003
Compositionally variable limu o Pele occurs in widely distributed sediments collected during ROV Tiburon dives along the Gorda Ridge axis. The fragments formed deeper than the critical depth of seawater and are unlikely to be formed by supercritical expansion of seawater upon heating in contact with hot lava. Discharge of CO 2 through erupting lava is

Application of Doppler radar (VOLDORAD) to the study of Strombolian eruptions dynamics at Etna

open access: gold, 2008
VOLDORAD, a low power UHF Doppler radar, is a portable ground-based system, developed by the Observatoire de Physique du Globe de Clermont-Ferrand (France), especially for the study of explosive volcanic activity. The capabilities of such remote sensing methods to probe safely hazardous eruption jets and plumes constitute a real step forward regarding ...

Volcanic Hot-Spot Detection Using SENTINEL-2: A Comparison with MODIS−MIROVA Thermal Data Series [PDF]

open access: yes, 2020
In the satellite thermal remote sensing, the new generation of sensors with high-spatial resolution SWIR data open the door to an improved constraining of thermal phenomena related to volcanic processes, with strong implications for monitoring ...

Recycled ejecta modulating Strombolian explosions [PDF]

open access: yes, 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 ...

High level sill and dyke intrusions initiated from rapidly buried mafic lava flows in scoria cones of Tongoa, Vanuatu (New Hebrides), South Pacific [PDF]

open access: yes, 2006
Scoria cones are generally considered to grow rapidly in days to weeks or months. During their growth lava flows may be fed onto the cone surface from lava-lake breaches, or form by coalescence of spatter; such flows are preserved interbedded with scoria

Tephra sedimentation and grainsize associated with pulsatory activity: the 2021 Tajogaite eruption of Cumbre Vieja (La Palma, Canary Islands, Spain)

open access: yesFrontiers in Earth Science, 2023
Long-lasting eruptions are of complex characterization and are typically associated with challenging risk assessment and crisis management due to the usual occurrence of multiple interacting hazards evolving at different temporal and spatial scales (e.g.,
