Spectrogram of the ATPC seismic station (Metauro upstream) on 15 September 2022. Black lines represent the hourly cumulated rainfall measured by the raingauges within 10 km from ATPC (please note that the names of the raingauges are listed in the legend and are highlighted in Fig. S1 of the Supplemental Material). The green line displays the hourly cumulated rainfall of the closest raingauge (i.e., 5.4 km away from ATPC).
