A new instrument has been developed and deployed for reception of broadband extremely low frequency (ELF) (defined in this paper as 300–3000 Hz) radio signals from sources related to seismic activity. The base is the designs used for decades at Abastumani Astrophysical Observatory and a concept representing the seismicity of Caucasus as a self-organizing criticality. We describe technical and application...
This article presents the results of observation of Extremely Low Frequency (ELF, 300–3000 Hz) electromagnetic radiation related to seismic activity in the period before and after strong M6.0 earthquake. Proper ELF radiation of the system of tectonic faults may indicate the state of activity and help to understand and interpret the data of ionosphere sounding by radio wave propagation study other...
