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. According to the monitoring data, the number of earthquakes with magnitudes 2.5–4 decreased in early 2017, but since February 2017, seismic activation has increased around the underground mine works, which was manifested as a significant increase in the number of low-energy technogenic earthquakes. In fact, the technogenic seismic hazard has shifted from open mine works towards the area of the operating underground mine.

The Bachat earthquake that occurred in Kemerovo oblast on June 18, 2013 with a local magnitude of ML = 6.1 is the strongest in a series of events in the vicinity of an open-pit mine of the same name, as well as the world’s largest technogenic earthquake in the extraction of solid minerals. Research on the seismicity in the environs of the mine using local networks of temporary stations began several years prior to the earthquake and continues today. We present the results of this research. Particular attention is given to monitoring of the seismic regime of technogenic activation of the Bachat coal mine and its nature.

The stress state of the Earth’s crust in the region of the Chuya earthquake of 2003 (Gorny Altay) is studied using the data of long-term epicentral observations by dense networks of temporary stations. These data comprise 545 seismic events, which widely vary in energies and whose parameters are determined highly accurately. Two hierarchical levels of the stress field are revealed and their spatial structure and temporal behavior are investigated. It is shown that the subregional stress field, which is determined from the data on strong earthquakes, is predominantly stable across the studied area, where the regime of horizontal shear with submeridional orientation of principal pressure axes is observed. The local stress field calculated from the weak seismic events experiences regular variations, which are consistent with the block structure of the crust; this field is heightand time-dependent.

The data on the world-strongest earthquake induced by hard mineral mining—Bachatsky earthquake (local magnitude 6.1) in Kuzbass on June 18, 2013—are reported. Seismic activation of the territory at the Bachatsky Open Pit Mine in 2012–2013 awoke three large earthquakes, sensibly affecting the Kuzbass towns. The authors have analyzed the results of experiments on temporal seismology nets in 2012 and the records of the after-shocks of the Bachatsky earthquake in 2013. The low energy seismic activity is revealed in rocks under the Bachatsky and Shestaki OPMs. It is found that small earthquakes cluster under the center of the open pit mine bottoms, and the larger earthquakes crowd under the pitwalls, and the depth of the earthquake sources is 3–4 km.

Data on the largest man-caused earthquake through the extraction of solid minerals on the Earth Bachatskoe earthquake (ML = 6.1), which took place on 18 June 2013 in Kuzbass are presented. Seismic activity in the area of a coal cut «Bachatskij» was accompanied three times in 2012-2013 by major earthquakes created appreciable impact on the locality of Kuzbass. In the article it is analysed the experiments with temporary networks of seismic stations in 2012 and at registration of aftershocks Bachatskoe earthquake in 2013.

Tuva earthquakes 27.12.2011, ML = 6.7 and 26.02.2012, ML = 6.8 occurred on the Kaahem fault in the Academician Obruchev ridge are considered. The epicental area of these earthquakes was aseismic during the period of instrumental observations (last 50 years). In our investigation we used seismological data of Altay-Sayan regional seismic network and temporary stations installed in epicental area between the Tuva-I and Tuva-II earthquakes.
