We inform you that starting from 4:00 today and up to 6:00, the seismic network of Ischia of the INGV-Osservatorio Vesuviano recorded a signal associated with landslides that affected the territory of the municipality of Casamicciola (Fig 1, seismic recording of the IOCA station - Grande Sentinella area). The data is confirmed by the spectrogram (Fig. 2, bottom graph which represents the frequency content over time) deriving from the analysis of the seismic signal (Fig. 2, top graph) recorded at the ICVJ station installed in loc. La Rita (southwest of Casamicciola).
