Absence of local lightning activity in north Italy.


Monitoring St. 01 - IK1QFK  CUMIANA (TO), NW Italy 

Geophone and Marconi antenna,  6214641 event marked with vertical white arrow. Schumann Resonances are on background but very interfered by signals coming from main network: all those horizontal lines. At very low frequency a signal like an hiss coming from a solar panel station, generated by inverter during the night. Seismic wave on top inside the dotted oval.  No RF signals correlated with earthquake event.

Marconi antenna (VLF electric filed),  6214641 event marked with vertical white arrow. Many statics, carriers coming from main network and Alpha Russian radionavigation system on top. No RF signals correlated with earthquake event.


Monitoring St. 01 - IK1QFK  CUMIANA (TO), NW Italy 

Two ICS101 orthogonal induction coils, 6214641 event marked with white vertical arrow. Schumann Resonances marked on left part, some interharmonic carriers, microphonic effect following the event generated by coil shaking, and trains start to passing early in the morning, 5km away . No RF signals correlated with earthquake event.


Monitoring St. 01 - IK1QFK  CUMIANA (TO), NW Italy 

Two ICS101 orthogonal induction coils, hourly strips, 6214641 event marked with white vertical arrow on left top. Schumann Resonances marked on left part on bottom, "green" microphonic effect generated by coil shaking follows the event , and trains start to passing early in the morning right after. No RF signals correlated with earthquake event.


Monitoring St. 02 - CSP VLF MONITORING STATION From Pontese dew (TO), NW Italy 

ADA floating electric field receiver on top, and aerial loop on bottom,  6214641 event marked with vertical white arrow. Wind shakes both sensor generating microphonic effect. No RF signals anomalies correlated with earthquake event.
