“…The results of the automated processing of singular stations were selectively validated. The average percentage of false positives detected was 22%, which is generally an acceptable result, coinciding with the results of the regional network's processing in prior years [Fedorov et al, 2019].…”

“…Since 2016 for continuous seismic monitoring in the western sector of the Russian Federation's Arctic zone the KB GS RAS is using NSDL -an automated software package designed to detect and locate seismic events [Fedorov et al, 2019]. NSDL processes data obtained by a total of 19 seismic stations of the international network located within the Kola Peninsula, in northern Norway, eastern Finland and the Spitsbergen archipelago.…”

This paper provides information about the main parameters of spatial broadband seismic network in the Kola region (the northeastern part of the Fennoscandian Shield). Since 2021 the seismic network has been expanded by five seismic stations and currently consists of nine stations located on the territory of the Russian Federation. Configuration of the network allows to broaden the scope of research of the Kola region lithospheric structure significantly. The prospects of integrating the newly installed stations into the automated regional seismic monitoring network are considered. The analysis of seismic noise in the places of installation of new seismic stations was carried out. It was shown that the data provided by the new broadband stations increases the accuracy of seismic events location in the research area.

“…Seismic receivers receive, record and store seismic data (Bin et al., 2021). The seismic data processing system can denoise, reshape and decode the collected data according to specific laws and even has the function of text display or voice broadcast (Fedorov et al., 2019). This section elaborates on the principles of seismic communication, introduction of facilities, encoding process, data acquisition, reconstruction and decoding theories.…”

Geophysical prospecting signals encompass subsurface structural information and incorporate textual messages generated in accordance with a specific pattern. These signals can be employed in places without radio access to ensure public and worker safety. Therefore, the use of seismic signals to transmit information through the earth has attracted the attention of researchers in the last decade. Presently, achievements in seismic communication are mainly in the coding, generation, and propagation of seismic signals. Little work has been done on methods to convert seismic signals generated by vibroseis sources into text and broadcast them vocally. Therefore, we built a seismic communication system with 6‐bit code using the American Standard Code for Information Interchange. To better recommend the seismic communication system scheme, the origin, state and principles of seismic communication system are illustrated in detail. Then, a seismic transmitting system is devised with a 500 N vibroseis source, which compiles seismic signals through amplitude modulation. After seismic signals propagate through the earth, they are received by geophones and recorded in seismographs. Through data acquisition based on a compression algorithm, seismic signals are converted into text and voice signals, which significantly reduces the storage and transmission of seismic data.
