In the fourth quarter of 2016, the system for monitoring induced seismicity in the Kuznetsk Basin (Kuzbass) began to record increasing seismic activity in the area of the Kaltan open-pit coal mine, which was struck by a series of seismic events felt in cities and settlements of the Kuzbass. In addition to the existing monitoring network, a temporary network of stations has been established, which has significantly increased the accuracy and representativeness of technogenic earthquake records. Markedly expressed seismic activation near open mine works (the Kaltan open-pit mine) has been revealed. The seismically activated area covers several open mine works and their vicinity. The strongest earthquakes have occurred outside the open-pit mine at the boundary of the dump. Inside the activated area, near the operating underground mine works (the Alarda mine), local seismic activation represented by low-energy technogenic earthquakes has been recorded. The largest number of perceptible earthquakes occurred in the fourth quarter of 2016.
