Ash Features from Ordinary Activity at Stromboli Volcano

open access: yesInternational Journal of Geosciences, 2014
In this work we focus our attention on micro-scale textural observations and chemical analysis of the surface of ash particles erupted from ordinary activity at Stromboli volcano (Aeolian Islands, Italy). Ashes are related to three vent systems: NE1, NE2 and SW showing different eruptive styles.

Developments in real-time radon monitoring at Stromboli volcano [PDF]

open access: yesJournal of Environmental Radioactivity, 2012
We present the results of one year of continuous radon monitoring at Stromboli volcano collected at two automated real-time stations. These were deployed on the NE flank (at 520 m a.s.l.) and within the summit area (900 m a.s.l.). Higher daily emissions at the lower station approached 4,200 Bq/m³, with bulk averages around 1,800 (±980) Bq/m³; whereas ...

Spectrogram analysis of selected tremor signals using short-time Fourier transform and continuous wavelet transform

open access: yesAnnals of Geophysics, 1999
Among a variety of spectrogram methods Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) were selected to analyse transients in non-stationary tremor signals.

Integration of Ground-Based Remote-Sensing and In Situ Multidisciplinary Monitoring Data to Analyze the Eruptive Activity of Stromboli Volcano in 2017–2018

open access: yesRemote Sensing, 2019
After a period of mild eruptive activity, Stromboli showed between 2017 and 2018 a reawakening phase, with an increase in the eruptive activity starting in May 2017.

Can vesicle size distributions assess eruption intensity during volcanic activity? [PDF]

open access: yesSolid Earth, 2013
We studied three-dimensional (3-D) vesicle size distributions by X-ray microtomography in scoria collected during the relatively quiescent Phase II of the April–May 2010 eruption at Eyjafjallajökull volcano, Iceland.

Modeling Tsunamis Generated by Submarine Landslides at Stromboli Volcano (Aeolian Islands, Italy): A Numerical Benchmark Study

open access: yesFrontiers in Earth Science, 2021
We present a benchmark study aimed at identifying the most effective modeling approach for tsunami generation, propagation, and hazard in an active volcanic context, such as the island of Stromboli (Italy).

Neural networks and dynamical system techniques for volcanic tremor analysis

open access: yesAnnals of Geophysics, 1996
A volcano can be seen as a dynamical system, the number of state variables being its dimension N. The state is usually confined on a manifold with a lower dimension f, manifold which is characteristic of a persistent «structural configuration».

MultiGAS Detection from Airborne Platforms on Italian Volcanic and Geothermal Areas

open access: yesRemote Sensing, 2023
The measurement of volcanic gases, such as CO2 and SO2, emitted from summit craters and fumaroles is crucial to monitor volcanic activity, providing estimations of gases fluxes, and geochemical information that helps to assess the status and the risk ...

Energy budget of the Volcano Stromboli, Italy

open access: yesGeophysical Research Letters, 1979
Field data, including eruption movies, are used to construct a budget of the various modes of energy transport for the volcano Stromboli, Italy. At least eight distinct energy transport mechanisms can be identified. In its "normal" steady state eruption mode, Stromboli delivers approximately 1.1 Mw of power to the surface by energy transport mechanisms

Interaction between seismicity and deformation on different time scales in volcanic areas: Campi Flegrei and Stromboli [PDF]

open access: yesAdvances in Geosciences, 2019
We study oscillations recorded at Stromboli and Campi Flegrei by different sensors: seismometers, strainmeters and tiltmeters. We examine both the high-frequency (>0.5 Hz) portion of the spectrum and very long period signals up to tidal scales.
