Short summary
Spectral analysis has been applied to seismic events recorded at Vesuvius volcano to test a new tool for a fast event classification. We computed two spectral parameters, central frequency and shape factor from the spectral moments. The results show that volcano-tectonic earthquakes and low frequency events are distinguishable though the spectral moments. Since the computation of spectral parameters is easy and fast, it may become an effective tool for classification in observatory practice.
