Induction coil, situation 6 hours before the event: a strong storm, preceded by wind fills all the spectrum with a signal similar to white noise.

Induction coil,  6096411 event marked with white arrow. Schumann Resonances marked on right part. Local storm ending on left part and strong low frequency noise before the event, but not correlated with earthquake event.

Induction coil,  6096411 event marked with white arrow. Schumann Resonances overpassed by local storm activity. Low frequency noise precedes the event, but not correlated with earthquake event.

Induction coil, daily strips,  6096411 event marked with white arrow. First Schumann Resonance marked on left part. Strong storm activity starting from 11:30 before the event and low frequency noise some hours before, like every day in the evening. Also a PC1 geomagnetic pulsation 4 days before the event. No RF signals correlated with earthquake event.
