Dynamical tools for the analysis of long term evolution of volcanic tremor at Stromboli
non linear analysis volcano trtemor state space reconstruction delayed coordinates
2015/10/8
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". This kind o...
Analysis and quasistatic FE modeling of long period impulsive events associated with explosions at Stromboli volcano (Italy)
volcano seismology long-period measurements Stromboli finite element calculations volcano sources
2015/10/8
Broadband seismic measurements performed in 1995 and 1996 in the summit region of Stromboli are analyzed. The experiment in 1995 used an array of four Guralp seismometers and one Wielandt-Streckeisen ...
Near-field seismic displacement and tilt associated with the explosive activity of Stromboli
Stromboli volcano seismology seismic tilt Mogi model source mechanism
2015/10/8
Broadband seismic recordings in the near-field of Strombolian explosions, at 500 m distance, show pronounced effects of tilt. The tilt signal is predominant in the horizontal components beyond about 5...
Seismological monitoring of the February 2007 effusive eruption of the Stromboli volcano
Stromboli volcano monitoring volcano seismicity
2015/9/2
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. The permanent br...
Tidal gravity observations at Mt. Etna and Stromboli: results concerning the modeled and observed tidal factors
Tidal gravity models Tidal loading
2015/9/1
Continuous gravity observations performed in the last few years, both at Mt. Etna and Stromboli, have prompted
the need to improve the tidal analysis in order to acquire the best corrected data for t...
First observational evidence for the CO2-driven origin of Stromboli's major explosions
CO2-driven origin Stromboli's major explosions
2014/12/31
We report on the first detection of CO2 flux precursors of the till now unforecastable "major" explosions that intermittently occur at Stromboli volcano (Italy). An automated survey of the crater plum...
Self-sustained oscillator as a model for explosion quakes at Stromboli Volcano
Self-sustained oscillator model for explosion quakes Stromboli Volcano
2009/11/12
We analyze seismic signals produced by explosion-quakes at Stromboli Volcano. We use standard nonlinear procedures to search a low-order effective dynam-ics. The dimension of the reconstructed phase s...
Statistical analysis of Stromboli VLP tremor in the band [0.1–0.5] Hz:some consequences for vibrating structures
Statistical analysis Stromboli VLP tremor band [0.1–0.5] Hz vibrating structures
2009/11/9
We analyze time series of Strombolian volcanic tremor, focusing our attention on the frequency band [0.1–0.5] Hz (very long period (VLP) tremor). Although this frequency band is largely affected by no...
