Explosive dynamics of violent Strombolian eruptions: The eruption of Parícutin Volcano 1943–1952 (Mexico)

Earth and Planetary Science Letters, 2008
Violent Strombolian is a term that was originally used by MacDonald [Macdonald, G.A., 1972. Volcanoes, Prentice-Hall inc., Englewood Cliffs, New Jersey, 510 pp.] to describe energetic Strombolian eruptions such as some of the more explosive phases of the 1943–1952 eruption of Paricutin Volcano (Michoacan, central Mexico), eruptions that disperse ...

Widespread strombolian eruptions of mid-ocean ridge basalt

Journal of Volcanology and Geothermal Research, 2009
Abstract Glassy lava fragments were collected in pushcores or using a small suction-sampler from over 450 sites along the Juan de Fuca Ridge, Blanco Transform Fault, Gorda Ridge, northern East Pacific Rise, southern East Pacific Rise, Fiji back-arc basin, and near-ridge seamounts in the Vance, President Jackson, Taney, and a seamount off southern ...

Strombolian explosions: 2. Eruption dynamics determined from acoustic measurements

Journal of Geophysical Research: Solid Earth, 1996
Strombolian activity consists of a series of explosions due to the breaking of a large overpressurized bubble at the surface of the magma column. Acoustic pressure due to sound waves has been measured and analyzed at Stromboli for more than 50 explosions.

Viscous plugging can enhance and modulate explosivity of strombolian eruptions

Earth 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 ...

Persistent activity and violent strombolian eruptions at Vesuvius between 1631 and 1944

Journal of Volcanology and Geothermal Research, 2008
Abstract During the period 1631–1944, Vesuvius was in persistent activity with alternating mild strombolian explosions, quiet effusive eruptions, and violent strombolian eruptions. The major difference between the predominant style of activity and the violent strombolian stages is the effusion rate.

Violent strombolian and subplinian eruptions at Vesuvius during post-1631 activity

Bulletin of Volcanology, 2001
On the basis of historical chronicles and field investigations the tephrostratigraphic sequence of post-1631 activity of Vesuvius is reconstructed. It has been established that, during this period, in addition to numerous totally effusive eruptions and/or normal strombolian activity, 16 explosive events produced well-traceable tephra deposits in the ...

Relative partitioning of acoustic and seismic energy during Strombolian eruptions

Journal of Volcanology and Geothermal Research, 2005
The relative elastic energy partitioning during Strombolian eruptions can be estimated from acoustic pressure and seismic velocity records. We outline methods for determining acoustic and seismic energies for sensors deployed within several kilometers of erupting vents.

Video and seismic observations of Strombolian eruptions at Erebus volcano, Antarctica

Journal of Volcanology and Geothermal Research, 2008
Abstract Between 1986 and 1990 the eruptive activity of Erebus volcano was monitored by a video camera with on-screen time code and recorded on video tape. Corresponding seismic and acoustic signals were recorded from a network of 6 geophones and 2 infrasonic microphones. Two hundred Strombolian explosions and three lava flows which were erupted from

Spatiotemporal variations in eruption style and magnitude at Yasur volcano, Vanuatu: part 2—extending Strombolian eruption classifications

Bulletin of Volcanology, 2020
In this companion study to Simons et al. (Bull Volcanol 82, 2020a), we examine Strombolian style explosive activity at Yasur (Vanuatu) over 11 weeks via seismic, thermal-infrared and visual observations. In part 1 of this study (Simons et al., Bull Volcanol 82, 2020a), we investigated the link between variations in the surface expression and style of ...

Infrasound from Tungurahua Volcano 2006–2008: Strombolian to Plinian eruptive activity

Journal of Volcanology and Geothermal Research, 2010
Abstract Strombolian to Plinian activity from Tungurahua Volcano, Ecuador has been recorded by the autonomous infrasound arrays of the Acoustic Surveillance for Hazardous Eruptions (ASHE) project since early 2006. Our studies suggest that acoustic energy release during large eruptions does appear to broadly scale with eruption intensity.
