Station 04 - ROMAGNA OBSERV. From Sogliano al Rubicone (FC), N Italy. ICS101 induction coil.
 
4004975321 event is marked with a white arrow. Schumann resonances marked on left part of spectrogram. No magnetic anomalies first, during or after the earthquake.


Station 04 - ROMAGNA OBSERV. From Sogliano al Rubicone (FC), N Italy. ICS101 induction coil.

4004975321 event is marked with a white arrow. First Schumann resonances always visible, and sometime local noise correlated with wind activity. No magnetic anomalies first, during or after the earthquake.

Station 05 - NORTHERN CROSS RADIOTELESCOPE From Medicina (IT - Bologna), N Italy.
Static electric field detected with Boltek Receiver.

Composite analysis with Station 04 - ROMAGNA OBSERV.  on top and Station 05 - NORTHERN CROSS RADIOTELESCOPE on bottom.

Spectrogram elaborated with Sonic visualizer. Here the time resolution is greater: in station 04 there are some strange noise bands before the event (in purple oval), seismic event marked with red line, followed by the effect microphone after the event due to the passage of the seismic wave. It is a very strange phenomenon that does not find other evidence during the day: it's as the background noise was put to pulse before the earthquake.
