Abstract
The software and hardware complex was selected on the basis of long-term monitoring observations. It allows to provide high-resolution seismological monitoring in adverse conditions. The use of low-power recording equipment makes it possible to choose the location of seismic stations at the maximum possible distance from man-made noise sources without connection to ground-based infrastructure. A two-stage analysis of the obtained seismograms makes it possible to detect the target seismic signals with minimal effort and determine the parameters of their sources even in the presence of a small number of seismic stations (starting from 3-4 units). The implemented approach made it possible to distinguish with certainty seismic events starting from magnitude ML = -0.5 occurring at a depth of 400 m to 1 km under conditions of a high level of background industrial noise.
