Implementation of electrochemical, optical and denuder-based sensors and sampling techniques on UAV for volcanic gas measurements: examples from Masaya, Turrialba and Stromboli volcanoes [PDF]

open access: yesAtmospheric Measurement Techniques, 2018
Volcanoes are a natural source of several reactive gases (e.g., sulfur and halogen containing species) and nonreactive gases (e.g., carbon dioxide) to the atmosphere.

Dynamical similarity of explosions at Stromboli volcano [PDF]

open access: yesGeophysical Journal International, 2004
SUMMARY We analyse Strombolian explosions recorded with broadband seismometers to quantify the degree of similarity among explosions. First, we construct the trajectory space. This reconstruction is analogous to that of phase space but, unlike the phase space which relies on the analysis of a single trajectory of a dynamic system, the trajectory space ...

What are VLP signals at Stromboli volcano?

open access: yesJournal of Volcanology and Geothermal Research, 2022
Abstract Understanding Very Long Period seismic signals (VLPs) observed before and during volcanic explosions is fundamental to better forecast them. The sources of VLPs, which have long been associated with fluid motions, have mostly been modeled by a fixed dislocating point source using classical seismology developed for tectonic earthquakes.

Spectral precursors of paroxysmal phases of Stromboli

open access: yesAnnals of Geophysics, 1996
In this work we investigate the characteristics of the seismicity at Stromboli volcano during more than two years, i.e. from 11 May 1992 to 21 August 1994.

Seismological monitoring of the February 2007 effusive eruption of the Stromboli volcano

open access: yesAnnals of Geophysics, 2007
On February 27, 2007, the Stromboli volcano, which has usually been characterized by moderate explosive activity, started an effusive eruption with a small lava flow down the NW flank.

Combined ground and aerial measurements resolve vent-specific gas fluxes from a multi-vent volcano

open access: yesNature Communications, 2020
Combining multiple ultraviolet cameras with synchronous aerial measurements, the authors here present vent-specific gas compositions and fluxes for Stromboli volcano.

Lava effusion — A slow fuse for paroxysms at Stromboli volcano? [PDF]

open access: yesEarth and Planetary Science Letters, 2011
Questo lavoro ha analizzato i risultati del monitoraggio termico delle eruzioni di Stromboli del 2002-2003 e 2007, ed ha mostrato come prima di ogni parossisma il volume di lava eruttato nel corso dell’attivita effusiva sia stato confrontabile.

Seismic Tomography Experiment at Italy's Stromboli Volcano

open access: yesEos, Transactions American Geophysical Union, 2008
Stromboli Island, located in the southern Tyrrhenian Sea, is the emerged part (about 900 meters above sea level) of an approximately 3‐kilometer‐high stratovolcano. Its persistent Strombolian activity, documented for more than 2000 years, is sometimes interrupted by lava effusions or major explosions.

Dynamical tools for the analysis of long term evolution of volcanic tremor at Stromboli

open access: yesAnnals of Geophysics, 1999
Stromboli is characterized by persistent seismic activity, both in terms of tremor and of discrete events associated with moderate explosions defining the so-called "Strombolian activity".

Interaction of seismic and air waves recorded at Stromboli Volcano

open access: yesGeophysical Research Letters, 1993
Explosion‐quake seismograms recorded at Stromboli show that seismic phases with a high‐amplitude and high‐frequency content propagate with a velocity of approximately 330 m/s ‐ the sound speed. The analysis of seismograms, recorded at a distance of 500 m from one of the three active vents, shows for the first onset a low‐frequency and particle motion ...
