They probably are related at some level though.
The Richter (sp?) scale does not record on an even level... a 4 reading is not twice a 2 reading for example... the ratio of a 5.9 reading and a 2.2 is not what one would expect; a 2.2 is not 2.2/5.9... I'm no expert but I would guess that a 2.2 is not a very large quake while I know 5.9 is 0.1 from the top of the moderate class and therefore pretty strong... so it might be felt greater than the local 2.2.
Just using logic with a little bit of knowledge here.
I've heard nothing of a foreshock on this and only about an aftershock... If that was a foreshock, I'd fear the real quake coming. Also this is the first I've heard of a major fault on the East Coast.
