Productivity of Mining-Induced Seismicity.

The paper addresses the study of the ability of mining-induced earthquakes to generate successive shocks. Based on the example of the Khibiny natural–technogenic system, it is shown that the number of the initiated shocks (the productivity) has the exponential distribution with the form independent on the magnitude and depth of the events. This result is consistent with the similar productivity law previously established for the tectonic earthquakes on the global and regional levels, expanding the validity of this law to the lower energy scales of seismic events ~104 J (M ≥ 0).
