Ash Features from Ordinary Activity at Stromboli Volcano

Waveform Variation of the Explosion-Quakes as a Function of the Eruptive Activity at Stromboli Volcano

Self-sustained oscillator as a model for explosion quakes at Stromboli Volcano

We analyze seismic signals produced by explosion-quakes at Stromboli Volcano. We use standard nonlinear procedures to search a low-order effective dynamics. The dimension of the reconstructed phase space depends on the number of samples. Namely larger time lengths correspond to dynamical systems of different complexity. If we restrict the analysis to the signal associated directly to the source...

Real-time inversion of VLP source functions at Stromboli Volcano, Italy

We present a comprehensive processing tool for the real-time analysis of the source mechanism of Very-Long-Period (VLP) seismic data based on waveform inversions performed in the frequency domain for a point source. A search for the source providing the best-fitting solution is conducted over a three-dimensional grid of assumed source locations, in which the Green’s functions associated with ea...

The April-May 2006 volcano-tectonic events at Stromboli volcano (Southern Italy) and their relation with the magmatic system

Between April 10th and May 22th 2006, a small seismic swarm of 5 volcano-tectonic events occurred on the volcanic island of Stromboli (Southern Italy). Two of these, having M > 3 and an intensity of about V-VI MCS, were clearly felt causing concern in the population. They were recorded during a period of increased explosive activity and were followed by two major explosions at the summit crater...

Decrypting geophysical signals at Stromboli Volcano (Italy): Integration of seismic and Ground-Based InSAR displacement data

We present the integration of seismic and Ground-Based Interferometric Synthetic Aperture Radar system (GBInSAR) displacement data at Stromboli Volcano. Ground deformation in the area of summit vents is positively correlated with both seismic tremor amplitude and cumulative amplitudes of very long period (VLP) signals associated with Strombolian explosions. Changes in VLP amplitudes precede by ...
