Induction coil,  5877751 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. A strong very low frequency noise starts two hours before the event, stopping a few minutes before.

Induction coil,  hourly strips, 5877751 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, 5877751 event marked with white arrow. First Schumann Resonance marked on left part. Here the strong very low frequency noise starts two 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.

Source file analyzed with Sonic Visualizer. Geophone and coil,  5877751 event marked with white arrow. Schumann Resonances on left part. Good detail of the noise preceding the earthquake. No RF signals correlated with earthquake event.

Monitoring St. 03 - ETNA RADIO OBSERVATORY From NICOLOSI (CT), Etna Park, Sicily, S Italy 

Source file analyzed with Sonic Visualizer, as before but with 55 minutes detail with earthquake event on center. Geophone and coil,  5877751 event marked with white arrow. Schumann Resonances on left part.  No RF signals correlated with earthquake event.
