| Statistical information on various aspects of seismicity help to detect trends and patterns |  |
| PPV estimate for an event of given Magnitude and location |  |
| Diverging trends in seismic parameters reflecting changes in stress and seismic deformation in the rock mass |  |
| Long-term variations in the nature of a mine's seismic emission sources |  |
| Identification of design elements that may carry increased seismic risk |  |
| Comparative seismic hazard ranking of working places (based on face configuration, geology, production rate, seismic history) |  |
There are well over fifty established short-, medium- and long-term seismic hazard quantification methods to choose from. What is suitable in a given mining situation depends on the nature of seismic response to mining, customer needs and the resources available for risk amelioration.
