I'm in Forest Hills (fifth story) and at first I thought it was the usual extreme wind we get because the windows were shaking heavily. Then it got worse and I realized what it was when I felt it through the floor.
I've felt at least one other in the last year or two here but my wife in the other room did not. This one was the strongest I've been through though.
East coast geology (older, harder rocks) causes earthquakes to feel about ten times stronger than a west coast earthquake. This is felt roughly the same as a 5.8 in California. That's enough to be notable, especially at a shallow depth.
