| Zusammenfassung |
| We apply Independent Component Analysis (ICA) to seismic signals
recorded at Stromboli volcano. Firstly, we show how ICA works
considering synthetic signals, which are generated by
dynamical systems. We prove that Strombolian signals, both tremor
and explosions, in the high frequency band (>0.5 Hz),
are similar in time domain. This seems to give some insights to
the organ pipe model generation for the source of these events.
Moreover, we are able to recognize in the tremor signals a low
frequency component (<0.5 Hz), with a well defined peak
corresponding to 30s. |
