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

Imaging of Erebus volcano using body wave seismic interferometry of Strombolian eruption coda [PDF]
Geophysical Research Letters, 2012 Seismic interferometry is a recently developed theory that allows for the recovery of a medium's impulse response between two points should randomly distributed sources of white noise, or equivalently, a multiply scattered equipartioned wavefield, be present throughout the medium. We exploit the extremely scattering nature of volcanic media and seismic

Anatomy of a Strombolian eruption: Inferences from particle data recorded with thermal video [PDF]
Journal of Geophysical Research: Solid Earth, 2015 AbstractOver the past decade, a proliferation of new technologies has pushed forward our ability to measure the dynamics of volcanic emissions as they exit, and ascend above, the vent. Measuring parameters of all particles as they exit the vent during an explosive eruption is the best way to gather parameters such as size, shape, velocity, and mass for

Petrologic and numerical modeling study of Strombolian eruption dynamics at Volcán Llaima (Chile)
, 2011 Le volcan Llaima se situe dans la zone volcanique sud des Andes, ~700 km au sud de Santiago du Chili. C'est l'un des volcans les plus actifs du pays avec plus de 50 éruptions depuis 1640. Le dernier épisode éruptif a duré deux ans et s'est terminé au milieu de l'année 2009.

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.

Shallow magma‐mingling‐driven Strombolian eruptions at Mt. Yasur volcano, Vanuatu [PDF]
Geophysical Research Letters, 2012 Mt. Yasur volcano (Vanuatu) has been increasingly recognized for its high‐frequency Strombolian eruptions. Strombolian activity is often regarded as a product of the rapid ascent of gas slugs originating from a deep magma, which mingle with a batch of shallow magma upon eruption.

Physical parameterization of Strombolian eruptions via experimentally‐validated modeling of high‐speed observations [PDF]
Geophysical Research Letters, 2012 Pressurized gas drives explosive volcanic eruptions. Existing models can predict the amount and pressure of gas in erupting magma, but application and testing of such models is currently limited by the accuracy of input parameters from natural systems.

Strombolian eruptions and dynamics of magma degassing at Yasur Volcano (Vanuatu) [PDF]
Journal of Volcanology and Geothermal Research, 2020 Open vent basaltic volcanoes account for a substantial portion of the global atmospheric outgassing flux, largely through passive degassing and mild explosive activity. We present volcanic gas flux and composition data from Yasur Volcano, Vanuatu collected in July 2018. The average volcanic plume chemistry is characterised by a mean molar CO2/SO2 ratio

Seismic Source Migration During Strombolian Eruptions Inferred by Very‐Near‐Field Broadband Seismic Network [PDF]
Journal of Geophysical Research: Solid Earth, 2021 AbstractWe analyze seismic waves excited by small Strombolian explosions to understand the source process of volcanic explosions. We deployed five broadband seismometers at only 100–300 m away from the active craters of Stromboli volcano, Italy. Moment tensor inversion of the entire seismic signals in the 0.05–0.2 Hz band locates the source at a depth ...

Plate tephra: Preserved bubble walls from large slug bursts during violent Strombolian eruptions [PDF]
Geology, 2013 We describe unusual "plate tephra" particles that provide key information about rarely observed processes that occur during volcanic eruptions. The tephra formed during the 2008-2009 eruption of Llaima volcano, Chile, and dispersed as far as 9 km from the vent.
