Data for the same earthquake reported by different agencies

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.

Bryant, AR (3058.8 km NW of epicenter) [Map] / Light shaking (MMI IV) / rattling, vibrating : The floor and bed are vibrating strongly. The house started making cracking sounds over the past 5 to 10 minutes. There's also a deep rumbling still happening!! Kind of a sideways-tilt for a brief second, made me a little dizzy. (inner-ear problems, I can tell immediately when something is not level or there's a slight shift) It usually takes about 37-45 minutes for me to feel an earthquake from Puerto Rico and 2-7 minutes when it's in Oklahoma.
