After comparing waveform fits based on the two planes of the input moment tensor, we find that the nodal plane (strike= 258.0 deg., dip= 69.0 deg.) fits the data better. The seismic moment release based upon this plane is 8.8e+27 dyne.cm (Mw = 7.9) using a 1D crustal model interpolated from CRUST2.0 (Bassin et al., 2000).
