We constructed three observation sites in northeastern Japan (Honjo, Kyowa, and Sennan) with condenser-type large plate electrodes (4 × 4 m2) as sensors supported 4 m above the ground and with pairs of reference electrodes buried vertically at 0.5 m and 2.5 m depth (with a ground velocity sensor at Sennan only).
Electrical signals of an earthquake (M6.3) in northeastern Japan were detected simultaneously with seismic waves.
Their waveforms were damped oscillations, with greatly differing signal amplitudes among sites.
Good positive correlation was found between the amplitudes of signals detected by all electrodes.
We propose a signal generation model: seismic acceleration vertically shook pore water in the topsoil, generating the vertical streaming potential between the upper unsaturated water zone and the lower saturated water zone.
Maximum electric earth potential difference was observed when one electrode was in the saturated water zone, and the other was within the unsaturated water zone, but not when the electrodes were in the saturated water zone.
The streaming potential formed a charge on the ground surface, generating a vertical atmospheric electric field.
The large plate electrode detected electric signals related to electric potential differences between the electrode and the ground surface.
