a Slip area distribution in the off-Kamaishi earthquake cluster. Circle size denotes rupture dimension estimated from corner frequencies. Small bars show centroid location uncertainties. The labels 2001 and 2008 indicate M~ 4.8 repeating earthquakes in those years. The earthquakes labeled A–C are events with magnitudes 2.4–3.6 that occurred from 1995 to 2008. This figure is modified from Uchida et al. (2012). b Coherence dependence on frequency for the waveforms of the 2001 and 2008 M~ 4.8 repeating earthquakes for 11 stations. A time window of 40 s was used for the calculation. The vertical line shows the observed corner frequency from spectral ratio analysis (Uchida et al. 2012)
