Geophone, hourly multistrips,  5884121 event marked with white arrow, followed by seismic signal detected (in white oval). A broadband noise, similar to a paroxysm,  starts at 05:10 and ends at 14:50, but the phenomenon is not documented by any other observatory. Another seismic event  n. 5886221 appears to at 13:52, not subject of our research.

Induction coil,  5884121 event marked with white arrow. Schumann Resonances marked on left part. Some tones coming from main network, a microphonic signal caused by wind shaking the coil. Like in the past event a strong very low frequency noise starts two hours before the event, stopping a few minutes before.

Induction coil,  hourly strips,  5884121 event marked with white arrow. Schumann Resonances marked on left part. Also here the strong very low frequency noise starts before the event is clearly identifiable.

Induction coil,  daily strips, 5884121  event marked with white arrow. First Schumann Resonance marked on left part. Here the strong very low frequency noise starts almost three hours before the event, stopping a few minutes before, be explained: it is present every day, at about the same time, Is origin is unknown, but we're sure: it can not be a precursor.
