Abstract
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 space depends on the number of samples. Namely larger time lengths cor- respond to dynamical systems of different complexity. If we restrict the analysis to the signal associated directly to the source (Chouet et al., 1997), we obtain a phase space dimen- sion equal to two. We reproduce this part of the signal with a simple single self-sustained oscillator.File in questo prodotto:
