ERO multistrip Geophone detection:
The time of the earthquake 4005155371 is marked
with a white arrow.
Followed, after a few minutes in the box square, pressure wave and
ERO Magnetic field below 35 Hz, multistrip hourly view, detected
with induction coil:
No magnetic anomaly detected first or during the event. Earthquake
4005155371 is marked with a white arrow, mirophonic effect of
surface wave in white oval some minutes later, Schumann resonances
marked on right. Power line
distribution noise (seems like a white noise) marked
in red box.
ERO Magnetic field below 35 Hz, detected with
marked with white arrow. No magnetic anomaly
detected coinciding with the event. Schumann resonances
marked on Left. Power line distribution noise (seems like a
white noise) and local daily noise marked in
red box .
ERO Magnetic field below 9
Hz daily representation, detected with induction coil:
Event 4005155371 marked with white
arrow. First Schuman resonances marked on right
Main disturbance in the red box: see how they look like
geomagnetic pulsations, but are present every day at the
No magnetic anomaly detected coinciding with the event.
Detail of source file, 35 minuts elaborated with Sonic
marked with violet. Geophone spectrogram on top, with event,
seismic pressure wave and surface pressure wave. Magnetic
field on bottom with power line distribition noise in red box,
seismic event violet line, surface wave microphonic effect on
coil marked in white oval, and Schumann resonances on right.
Even here no
magnetic anomaly detected coinciding with the event.
