Comparison between the M2007 (M4.8) and A2010 (M4.2) events. a The vertical components of the raw velocity seismograms for M2007 and A2010, with the onset of the P-wave responses magnified in the inset. The orange zones mark the 0.1-s time interval where the larger and smaller events possess similar initial seismic responses. Slip rate histories for b M2007 and c A2010, projected onto common spatial coordinates. The highlighted slip history panels indicate the near-identical early slip histories
