Since 1994, a station has been functioning at a mountainous site of Zante island
(37.76 N - 20.76 E) in the Ionian Sea (western Greece) with the following configuration:
 six loop antennas detecting the three components (EW, NS, and vertical) of the
variations of the magnetic field at 3 kHz and 10 kHz respectively.
three customized loop antennas detecting the magnetic field from 100Hz up to 100KHz
two vertical loop antennas detecting the magnetic field at 82kHz
and 120kHz respectively.

two vertical ë/2 electric dipole antennas detecting the electric field variations
at 41 and 46MHz respectively, and
one antenna detecting the electric field variations at 140MHz
two Short ThinWire Antennas (STWA) of 100m length each, lying on the Earth's
surface, detecting ultra low frequency (ULF) (<1 Hz) anomalies in the EW and
NS directions respectively
Recently a magnetotelluric station has also been installed
All the EM time-series were
sampled once per second, i.e sampling frequency 1 Hz.
