Shallow velocity model of the Northern Flank of Stromboli Volcano, deducedby high frequency surface wave dispersion

The wavefield produced by the Stromboli volcano explosion quakes shows a si gnificant amount of surface waves. Rayleigh waves recorded by a linear arra y have been investigated to infer the shear-wave velocity model of the Stro mboli northern flank. The group velocity dispersion curve was obtained usin g the multiple filter technique, while the phase velocity dispersion curve was calculated both by phase-matched filtering and performing a p-omega sta ck on the observed waveforms. Through the inversion of these curves we were able to recover the shear-wave structure to a depth of about 190 m.
