After comparing waveform fits based on the two planes of the input moment tensor, we find that the nodal plane (strike= 293.0 deg., dip= 7.0 deg.) fits the data better. The seismic moment release based upon this plane is 7.1e+27 dyne.cm (Mw = 7.8) using a 1D crustal model interpolated from CRUST2.0 (Bassin et al., 2000).
