Tiny Ottawa earthquake M3.1

Hard on the heels of a mining event, we get a real earthquake near Ottawa.  This earthquake means nothing, but it is at an interesting place.  All down the river, we have these giant deposits of Leda Clay.  That means two things:  first, the ground motions will be amplified tremendously, and second, a big earthquake will cause a lot of these deposits to go 'whoosh' into the river.
