This earthquake occurred near the site of a M=5.8 event on Thursday, 15 July 2004.
Hmm... should we be concerned that a slightly smaller earthquake happened just a few days earlier in the same area?
I'm no expert but I know an earthquake followed by a bigger earthquake shortly after usually isn't a good sign.
