Tulsa, OK, Apartment 2nd floor, working at home an (277.1 km E of epicenter) [Map] / Very weak shaking (MMI II) / horizontal (sideways) swinging / 1-2 s : This happened at exactly 3:20am CST, my chair isn't the sturdiest but I sit still and I can tell when it is the ground shaking, it was a sway back and forth for a second or two. I noticed there was a report with about a 50 minute difference from the time it was reported and when I felt it where I am. Not sure if this is related to this quake though.
