Abstract

An approach to monitoring of electromagnetic earthquake precursors including variations of the apparent resistivity, electrotelluric fields, electromagnetic emission, and ionospheric disturbances perspective for short-term and mid-term earthquake prediction is considered. Parameters of hardware-software systems for audio- and radiomagnetotelluric soundings used in the monitoring of these precursors in a wide range of frequencies from 0.1 Hz to 1 MHz are described. The technique for the stress-strain sensitive area selection for the creation of monitoring networks based on the analysis of geological and geophysical characteristics of seismo active regions, study of geoelectric structures of preselected sites, and monitoring test sessions with the assessment of the response on tidal media deformations is presented. Recommendations on the recording technique of earthquake electromagnetic precursors are provided.
