After comparing waveform fits based on the two planes of the input moment tensor, we find that the nodal plane (strike= 232.0 deg., dip= 61.7 deg.) fits the data better. The seismic moment release based upon this plane is 5.2e+27 (Mw = 7.7) using a 1D crustal model interpolated from CRUST2.0 (Bassin et al., 2000).
