GROUND-BASED STATIONS

 

The ground-based stations of the Demeter programme follow several objectives:

  1. To seek and identify the abnormal variations in the ULF, ELF, and VLF frequency domains likely to be generated by a tectonic activity,
  2. To discriminate the origin of the signals (anthropogenic origin or tectonic),
  3. To evaluate the localization of the source(s),
  4. To evaluate propagation processes of the EM signals.
