Living On The Craton Boundary

Earthquakes can cause objects to fall off your shelves; this might come as a surprise in areas not typically known for earthquakes.

I came into my office this morning to discover some books had fallen off the bookshelf. Hum. Those were heavy books.

Then I remembered that the Craton boundary is REALLY active right now, and Texas (where I live), Oklahoma (north of me), and states from Tennessee to Montana are moving.

Since I live on the Craton, there must have been some movement during the night that knocked those books off my shelf.
