4.2 Michigan - Skywise - 05-03-2015
http://earthquake.usgs.gov/earthquakes/eventpage/us20002avh#general_summary
Rattled quite an area. I'm sure that frayed a few nerves.
I had lived not 20 miles south of the epicenter for a short time when I was a kid.

And a news article:

The focal mechanism (in the USGS link) is strike-slip with ENE-WSW shortening. The maximum principle (principal?) stress axis is generally ENE-WSW in eastern USA, although I think the Virginia quake a few years ago was not consistent with that.
