 Some OpenLab Source files:

Station 01 -CUMIANA (TO), NW Italy . Geophone/Marconi antenna.

4004959511 event is marked with a white arrow. Some mirrored signals, rain effects and Schumann resonances marked on right part. In left part an electrical discharge due to the accumulation of static field, a common phenomenon with clouds at low altitude. No magnetic anomalies first, during or after the earthquake.


Station 01 -CUMIANA (TO), NW Italy. Multistrip daily Electric field, detected with Marconi antenna.

4004959511 event is marked with a white arrow. Daylight wind activity, rain and Schumann Resonances.
No magnetic anomalies first, during or after the earthquake.
