My birthday earthquakes

I'll accept these two beauties as my birthday earthquakes.  Below M2, they only exist because of dense instrumentation.  Still they are part of the group triggered by the dammed lake.  We hope they are not part of a growing mechanism and everything continues to stay at the 2 level.  I often wonder what Virginia would have looked like had they such instruments before that M6.
