Short summary
We present a detailed analysis of the atypical low frequency seismicity occurred at Mt. Vesuvius in 2003-2018. The different decay patterns of the spectra, the existence of families as well as single events, the wide seismogenic volume, indicate that these events are caused by distinct source mechanisms: slow brittle failure in dry rocks and resonance of fluid-filled cracks. On these basis, we classified the earthquakes as Low Frequency (LF) and Long Period (LP).
