Abstract

Active development of coal deposits is underway in the area of some Northern Sea Route strongholds, which is regularly recorded by the seismic stations Amderma1 (AMDE1) and Kolba (KOLBA) of the Federal Center for Integrated Arctic Research, Ural Branch, Russian Academy of Sciences (FECIAR UrB RAS), located on the Kara Sea coast. The main task of the study is a comprehensive analysis of the work of the AMDE1 and KOLBA stations, which will create conditions for cleaning seismic catalogs from man-made events. The location of events in this case is not a determining criterion, since there is a large error in processing data from a single station. As a result, we have compiled a unique set of criteria for identifying the nature of local seismic events for each seismic station. These criteria have been implemented in the processing when analyzing the waveforms from the AMDE1 and KOLBA stations, which ultimately improves the quality of operation of the FECIAR seismic network of the Ural Branch of the Russian Academy of Sciences.
