Kolyvan earthquake 09.01.2019 with ML = 4,3 is named after the anthracite mining section of the same name. Since 2010, there has been an increase in seismicity around the cuts in the Gorlovsky coal basin (Novosibirsk region), which is caused by an increase in coal production in this field.It is proved that we are dealing with induced seismicity near the cuts, the largest of which is Kolyvansky. For the Gorlovka basin, in general, a graph of earthquake recurrences was constructed, which in its slope is significantly different than for natural earthquakes of the Altai-Sayan mountain region and for man-made earthquakes of Kuzbass.The Kolyvan earthquake was confidently recorded by stations in Russia and many foreign countries, and at the same time, the shakiness of the day surface near the epicenter does not correspond to the macroseismic equation and stretches southward, which is associated with a significant role of the depression structure.
