M3.9 Mining earthquake in Canada

M3.9.  At first it looks like it's in the middle of nowhere.

But then, zoom in.

You can see mine workings.  This is large for a rockburst.  I wonder what sort of mess it left.  Hope nobody was killed.

Update:  I may be full of compost!  This is a horrible clear cut and not mining.  Thus, we have a legit earthquake in the middle of nowhere.
