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

A cross-comparison of thermal infrared versus ultraviolet ground-based retrievals of SO2 masses during Strombolian explosions

Volcanica
This study investigates sulfur dioxide (SO2) emissions from Stromboli’s explosive activity using ground-based remote sensing techniques. We analyze the SO2 mass derived from ultraviolet (UV) and thermal infrared (TIR) cameras, alongside explosion ...

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.

Changes in the Redox State of the Nishinoshima Magmatic System During and After the 2020 Explosive Eruption

Island Arc
Intermittent volcanic activity has continued at Nishinoshima volcano in the Izu–Bonin arc in the western Pacific since 2013, characterized mostly by effusive Strombolian eruptions (Episodes 1–3).

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 ...

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:

Coeval strombolian and vulcanian type explosive eruptions at Panarea (Aeolian islands)

2008
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 ...
