Midland, Michigan / not felt / rattling, vibrating / 5-10 s : On Saturday, Sept. 19, 2020 I was in my hotel room on the third floor and suddenly I felt the floor shaking and the lamp on my desk was shaking for 5-10 seconds. My son and his girlfriend also witnessed the lamp shaking. It was a very quiet morning. There was very little action in the area. My brother later reported an earthquake near Los Angeles, CA. Several years ago I had been sitting on a park bench in Midland, Mich. and the bench started to shake for a few minutes. It was also reported late
