Scoria cone formation through a violent Strombolian eruption: Irao Volcano, SW Japan

Bulletin of Volcanology, 2013
Scoria cones are common volcanic features and are thought to most commonly develop through the deposition of ballistics produced by gentle Strombolian eruptions and the outward sliding of talus. However, some historic scoria cones have been observed to form with phases of more energetic violent Strombolian eruptions (e.g., the 1943–1952 eruption of ...

Gas‐Pyroclast Motions in Volcanic Conduits During Strombolian Eruptions, in Light of Shock Tube Experiments

Journal of Geophysical Research: Solid Earth, 2020
AbstractIn a Strombolian volcanic eruption, bursting of a pressurized gas pocket accelerates a mixture of gas and pyroclasts along a conduit and out of a vent. While mixture ejection at the vent is the subject of direct geophysical measurements, and a key to eruption understanding, the dynamics of how the mixture moves in the conduit are not observable

Machine learning as a detection method of Strombolian eruptions in infrared images from Mount Erebus, Antarctica

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.

Strombolian, Hawaiian and Plinian Eruptions and the Mount St. Helens Eruption 1980

2004
Europeans who choose not to spend their money on New Years Eve on fireworks, can instead book a flight to Naples and take a 2-h boat trip to the Aeolian Islands. They can climb the steep slopes of 960-m-high Stromboli volcano and enjoy natural fireworks every 10–20 min, all year-round.

Acoustic source characterization of impulsive Strombolian eruptions from the Mount Erebus lava lake

Journal of Volcanology and Geothermal Research, 2008
Abstract We invert for acoustic source volume outflux and momentum imparted to the atmosphere using an infrasonic network distributed about the erupting lava lake at Mount Erebus, Ross Island, Antarctica. By modeling these relatively simple eruptions as monopole point sources we estimate explosively ejected gas volumes that range from 1,000 m 3 to ...

Subaqueous strombolian eruptions, and eruption-fed pyroclastic deposits in a Paleoproterozoic rifted-arc: Hidden formation, Flin Flon, Canada

Precambrian Research, 2018
Abstract The Hidden formation of the Paleoproterozoic Flin Flon arc assemblage comprises the stratigraphic hanging wall to the volcanogenic massive sulfide (VMS) deposits at Flin Flon, Manitoba, Canada. It represents a basaltic volcanic edifice erupted within a large subsidence structure developed in a rifted-arc environment.

Coeval strombolian and vulcanian-type explosive eruptions at Panarea (Aeolian Islands, Southern Italy)

Journal of Volcanology and Geothermal Research, 2008
In this paper, we document the evolution of the emergent Panarea dome in the Aeolian islands (Southern Italy), placing particular emphasis on the reconstruction of the explosive events that occurred during the final stage of its evolution. Two main pyroclastic successions exposing fall deposits with different compositions have been studied into detail:

The violent Strombolian eruption of 10 ka Pelado shield volcano, Sierra Chichinautzin, Central Mexico

Bulletin of Volcanology, 2018
Pelado volcano is a typical example of an andesitic Mexican shield with a summital scoria cone. It erupted ca. 10 ka in the central part of an elevated plateau in what is today the southern part of Mexico City. The volcano forms a roughly circular, 10-km wide lava shield with two summital cones, surrounded by up to 2.7-m thick tephra deposits preserved

In this paper, we document the evolution of the emergent Panarea dome in the Aeolian islands 14 (Southern Italy), placing particular emphasis on the reconstruction of the explosive events occurred 15 during the final stage of its evolution. Two main pyroclastic successions exposing fall deposits with 16 different compositions have been studied into ...

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.
