Abstract
The authors analyze weak seismic activity at the Korobkovo iron ore deposit in the area of the Kursk Magnetic Anomaly. A sensing system in use enabled recording seismic events with a magnitude from –2.5 to –1.4 induced by a large-scale blast. Localization of hypocenteres was accurate to \(\sim50\) m. The most of origins of the recorded events occurred in the neighborhood of a faulting zone across the zone of mining, and at the interface of bed series. The values of a seismic moment of the events are within of two orders of magnitude \(10^{5}{-}10^{7}\) N\(\,\cdot\,\)m at an angular origin frequency of 70–600 Hz. The estimated seismic energy ranges from 0.0006 to 1 J. The reduced seismic energy values from \(2\cdot10^{-9}\) to \(2\cdot10^{-7}\) J/(N\(\,\cdot\,\)m) and the low velocities allow categorizing the recorded events as slow earthquakes.
