Preliminary model I is constrained by teleseismic data from global GSN seismic stations with USGS hypocenter location.
Preliminary model I' is constrained by teleseismic data from global GSN seismic stations with USGS hypocenter location.
Model I' is only an update for the Model I, but not an update of our preferred slip model. We used the same setup as the Model I, but increased the maximum slip limit from 40 m in the Model I to 60 m in the Model I'. It is NOT a preferred slip model.
Preliminary model II is constrained by teleseismic data from global seismic stations with JMA hypocenter location.
Preliminary model III is constrained by teleseismic data from global seismic stations with JMA hypocenter location.
The alignments of body and surface waves have been calibrated using the Mar. 9, 2011 Mw 7.5 Honshu Earthquake.
