After comparing waveform fits based on the two planes of the input moment tensor, we find that the nodal plane (strike= 6.0 deg., dip= 19.0 deg.) fits the data better. The seismic moment release based upon this plane is 2.9e+28 (Mw = 8.2) using a 1D crustal model interpolated from CRUST2.0 (Bassin et al., 2000).
