As before but in detail the range below 4 Hz, 6068821 event marked with red vertical line, detail of SRS.  To be observed that despite the proximity, geomagnetic pulsations are not received in the same way, due to different orientation of the two induction coils, set to have the minimum hum noise. No RF signals correlated with earthquake event.
