S-wave seismograms of (a) M4.7 and (b) M3.1 earthquakes at the station N.TRUH. Color lines indicate the three time windows used in deconvolution, which were (S0) −0.50 to 4.61 s, (S1) 0.78 to 5.89 s, and (S2) 2.06 to 7.17 s after S arrival. Each time window has 512 data points. c Deconvolved spectra with the fitted omega squared model. Color lines are deconvolved source spectra, that is, (a) divided by (b) for the individual three time windows. The black broken line shows the fitted omega squared model
