aIn the case of the Darfield event, only the fault dip and bottom depth were free to vary in the inversion. The stress drop (DeltaSigma) for the contiguous segments 1-5 (using an average width of 10 km) and the other individual segments is calculated from the segment moment M0, width W and length L using the relation DeltaSigma = 2M0/(PiW2L) [Scholz, 2002]. The latitude/longitude locations for the faults are the centroid for GCMT, the Preliminary Determined Epicenter (PDE) for the USGS Body Wave solution (USGS) and the updip projections of the fault segment center to the surface for the InSAR solutions.
