Vero Beach Florida (6137.2 km WNW of epicenter) [Map] / Light shaking (MMI IV) / rattling, vibrating / 20-30 s : Rattling and shaking lasted 20-30 seconds. At first I thought it was a sound effect of surround sound but turned off tv and it was still going. Went outside and it was still going. Went back inside. It seemed to fade and then gave a final shudder during which the whole building rattled and creaked. | 2 users found this interesting.
Vero Beach Florida (6139.7 km WNW of epicenter) [Map] / Light shaking (MMI IV) / 20-30 s : Light shaking inside, enough so that I went outside and could feel it too. Seemed to fade after 20-30 seconds and then had a 10 second shudder at the end where the building shook. Seemed more external though - nothing fell inside the building. | 2 users found this interesting.

Shawboro, NC / Very weak shaking (MMI II) : A friend and I were in a above ground pool. We heard something that we initially thought was the pool vacuum bouncing into the pool steps; then we thought it was something coming from the rain drain pipe at back of house. We kept hearing it on and off for about 15 minutes then it stopped. | 2 users found this interesting.
