Location Uncertainties in Passive Seismic Monitoring

In this study we shall address the effects of the receiver geometry, arrival time uncertainty and velocity model errors on location uncertainties. The effect of the velocity model error will be limited to a consideration of homogeneous media, although heterogeneity may have as profound effect on location accuracy as receiver distribution. Although many different sensor distributions are conceivable, we will focus on those that are most commonly applied in practice to include a 2-D grid of receivers on the earth’s surface and linear arrays of receivers in vertical boreholes.
