Hi Shenon. Not sure what you want me to say. Yes it would seem there were two small shocks associated with the 6.1 which occurred very rapidly afterwards.
Since all three of these events are being carried by USGS and EMSC i would imagine them to be correct. I have just checked them out on JMA and they are all there as well.
By the way they are 6.0, 4.5 and 4.6 on JMAedit on 21/4/2011 by PuterMan because: (no reason given)
This is a computer-generated message -- this event has not yet been reviewed by a seismologist.
