Station 04 - ROMAGNA OBSERV. From Sogliano al Rubicone (FC), N Italy. ICS101 induction coil.
4005046801 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 05 - NORTHERN CROSS RADIOTELESCOPE From Medicina (IT - Bologna), N Italy.
Static electric field detected with Boltek Receiver.


4005046801 event is marked with a red arrow. Ordinary electric activity: first, during or after the earthquake.


Station 05 - NORTHERN CROSS RADIOTELESCOPE From Medicina (IT - Bologna), N Italy. Magnetic field detected with ULFO induction coil.

4005046801
event is marked with a white arrow. Schumann resonances marked on left part of spectrogram. Not evident magnetic anomalies first, during or after the earthquake.



Station 05 - NORTHERN CROSS RADIOTELESCOPE From Medicina (IT - Bologna), N Italy. Magnetic field hourly strips detected with ULFO induction coil.

4005046801 event is marked with two white arrows, at strip end and strip start.


Station 05 - NORTHERN CROSS RADIOTELESCOPE From Medicina (IT - Bologna), N Italy. From 2015-03-03 20:00 to 2015-03-04 04:00.
Spectrogram elaborated with Sonic visualizer.  Eight hours across the 4005046801 event, marked with a red arrow in the centre of spectrogram. Schumann resonances marked on rigt part. Some spikes seem to precede the event but they are present again later.


Composite analysis with
Station 04 - ROMAGNA OBSERV.  on top and Station 05 - NORTHERN CROSS RADIOTELESCOPE on bottom. From 2015-03-03 20:00 to 2015-03-04 04:00.
 

Spectrogram elaborated with Sonic visualizer.
Fifty minutes across the 4005046801 event, with St.05 signal on top and St.04 on bottom. The 4005046801 event is marked with white arrows. Here we see clearly that the spikes received from the station 05 are not received from the station 04, which is located at the same distance from the event. They, therefore, are  probably disturbances of local origin.
