Introduction
In this study, 73 broadband P-waveforms are used for the point-source moment-tensor
inversion and for the finite-fault model inversions for Event 1 and Event 2. Distribution
of the 73 stations which recorded broadband P-waves is shown in the Postscript file
“fs01.eps”. Comparison of the observed and synthetic waveforms for the point-source
moment-tensor inversion and finite-fault slip inversion for Event 1 are shown in the
Postscript files “fs02-1.eps”/”fs02-2.eps” and “fs03-1.eps”/”fs03-2.eps”, respectively.
The Postscript file “fs04.eps” shows example of residual waveforms used to estimate
the finite-fault model for Event 2. The Postscript files “fs05-1.eps/fs05-2.eps” show the
comparison of the residual and synthetic waveforms for the finite-fault slip inversion for
Event 2. The Postscript file “fs06.eps” shows the ΔCFF distribution by Event 1 for
Event 2 as a receiver fault in the case of μ’= 0.0 and 0.8. The Postscript files “fs07.eps”
and ”fs08.eps” show ΔCFF distribution by the 2011 Tohoku earthquake for Event 1 and
Event 2 as receiver faults in the case of μ’= 0.0 and 0.8, respectively.

show the observed waveforms and the synthetic waveforms
from Event 1, respectively. Blue waveforms show the
residual waveforms (Solid part: used in the inversion, dashed
part: not used in the inversion).
