Statistical moments of power spectrum: a fast tool for the classification of seismic events recorded on volcanoes
Spectral analysis has been applied to almost thousand seismic events recorded at Vesuvius volcano (Naples, southern Italy) in 2018 with the aim to test a new tool for a fast event Drinks Pail classification.We computed two spectral parameters, central frequency and shape factor, from the spectral moments of order 0, 1, and 2, for each event at seve
