Comparison of observed and synthetic seismograms for the earthquake (\({\mathrm{M}}_{\mathrm{w}}=4.0\)) that occurred at 9:06, March 16, 2011 (JST). The black and red lines show observed and synthetic seismograms, respectively. The station numbers are shown in Fig. 1b. The white-colored area shows the used time windows. Note that we did not use station #05, because the raw seismogram before applying the bandpass filter was saturated in 5 s from the beginning of the time window
