Earthquake in Michigan

Did anybody feel the earthquake yesterday? I didn't but my mom, cousin and grandfather did and they're on the other side of the state. Some people felt it back on campus in Muskegon. I guess we were to busy working to feel anything but it happened on the same side of the state I'm on. And I work a 1hr and a half from Muskegon. It was only a 4.0. It just freaked out a lot of people.
