this is indeed very strange..
I'm no Earthquake expert, but I do monitor the USGS/ECETI websites most days, and am pretty adept at spotting patterns.
In 3 or four years of monitoring, I've never seen this pattern before, nor this many repeatedly strong aftershocks.... and there are so many "aftershocks" at same 10km depth, over the region, it is weird:
