Quantitative seismological analysis yields source parameters relating to stress and strain in the source region. Parameters such as seismic viscosity help to distinguish between rock volumes of different strain behaviour. Recorded seismic strain scales aseismic strain (specifically fault creep). Applications of these concepts to the characterisation of fault behaviour are presented, with specific reference to lower order moment tensor analyses. In the mining environment a unique opportunity exists to verify moment tensor analyses by physical inspection of the sources of seismic events. One application of quantitative seismic monitoring could be for the evaluation of the effect of reservoir depletion on faults with earthquake potential.
