Verkhnekamskoye potash deposit (VPD) is the only exploited potash deposit in Russia. It is second in the world on reserves after the Saskatchewan deposit in Canada. The first mine at the VPD was brought into production in 1933. Intensive mining began in the middle of the 1980 s, when 6 mimes were in operation. Ores are extracted from potash beds at the depths of 200-400 meters below surface. There is no evidence of any natural seismic activity in the vicinity of the potash mines prior to the beginning of mining. Large induced seismic events with magnitudes 2.6-4.7 that were felt by residents appeared in the 1990 s. The epicentres of these earthquakes were w ithin the VPD boundaries. Since 1995 underground monitoring systems were installed in all 6 working potash mines. Fifteen years of monitoring enabled accurate observation of induced seismicity at mines.
