Physics of the Earth and Planetary Interiors, 2020 Abstract Mount Erebus, Antarctica, has a persistent lava lake with Strombolian eruptions. Volcanic eruptions can be automatically detected with multiple methods such as cross-correlation of seismic recordings and identifying anomalies in gas emissions.

Parameterizing the Dynamics of Strombolian Eruptions through High-Speed Video Analysis
, 2011 Strombolian explosive activity is generally characterized by a series of short, mild explosions caused by the bursting of large individual gas pockets at the magma free surface; however individual explosions at Stromboli Volcano (Italy) show how these events can be complex and heterogeneous.

Laboratory models of Hawaiian and Strombolian eruptions
Nature, 1988Basaltic eruptions are often characterized by cyclic changes of activity. At Hawaii, periods of continuous fountaining alternate with much longer periods of effusive outflow1,2. In Strombolian eruptions, activity proceeds through intermittent discrete bursts2–5. We report laboratory experiments that simulate the degassing process in basaltic eruptions.

Widespread strombolian eruptions of mid-ocean ridge basalt
Journal of Volcanology and Geothermal Research, 2009Abstract 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, 1996Strombolian 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.

Persistent activity and violent strombolian eruptions at Vesuvius between 1631 and 1944
Journal of Volcanology and Geothermal Research, 2008Abstract 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, 2001On 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 ...

Video and seismic observations of Strombolian eruptions at Erebus volcano, Antarctica
Journal of Volcanology and Geothermal Research, 2008Abstract 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

Infrasound from Tungurahua Volcano 2006–2008: Strombolian to Plinian eruptive activity
Journal of Volcanology and Geothermal Research, 2010Abstract 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.
