Description
Summary:The project of the joint seismic-and-electromagnetic monitoring in low-ambient noise areas is aimed at studying the phenomena associated with the deformation of the Earth’s crust. The arrangements set of the geophysical monitoring in low-ambient noise areas is proposed. The paper describes in detail the technological scheme being of monitoring of the modern geodynamic activity with a magnetotelluric soundings method and a small seismic array presented as the seismic gradient system (SGS). Technical explanations, safety rules, equipment calibration and maintenance, and the technological schemes of the method of obtaining and archiving data are given. Maintenance procedures using SGS with geophones in Tien Shan to determine the endogenous component of the seismic field are described. We investigate a common workflow chart for SGS and main programs for the data caption and data processing. The proposed scheme has been tested and requires the application and adoption to the passive geophysical monitoring routine.
